BILOXI, Miss. - The lead singer of 3 Doors Down is recovering at home from injuries sustained in a one-car accident on a rain-soaked Mississippi road earlier this month.

Brad Arnold, 27, was a passenger in the car driven by his wife, Terika, when the accident occurred on Feb. 1, according to the band's Web site.

Terika Arnold reportedly wasn't injured.

"They were coming back from a casino, hit some kind of water on the road. The car hydroplaned, went down a high embankment and they hit a tree. I guess if Brad hadn't been wearing his seat belt, he'd probably be dead now," band member Todd Harrell said Thursday.

Harrell said Arnold has "35 or 40 stitches in the side of his face."

"He had a plastic surgeon come in and work on him, sewed his ear back on," Harrell said. "He's going to be all right. He was hit hard, though."

Harrell said the band, originally from Escatawpa, plan to tour Europe next month. They have been promoting their third studio album, "Seventeen Days."

Their hits include "Let Me Go," "Kryptonite," "When I'm Gone" and "Here Without You."

Actor Who Played 'Jeffersons' Neighbor Dies

Actor Who Played 'Jeffersons' Neighbor Dies

By Associated Press
4 hours ago

LOS ANGELES - Franklin Cover, who became a familiar face as George and Louise Jefferson's white neighbor in the long-running TV sitcom "The Jeffersons," has died, his publicist said Thursday. He was 77.

Cover died of pneumonia Sunday at the Lillian Booth Actor's Fund of America home in Englewood, N.J., said publicist Dale Olson. He had been living at the home since December 2005 while recuperating from a heart condition.

In his nearly six decades in show business, Cover made numerous appearances on television shows, including "The Jackie Gleason Show," "All in the Family," "Who's the Boss?" "Will & Grace," "Living Single," "Mad About You" and "ER."

He began his career on the stage, appearing in Shakespeare's "Hamlet" and "Henry IV," and later in numerous Broadway productions, including "Any Wednesday," "Wild Honey and "Born Yesterday."

But Cover was best known for his role as Tom Willis, who was in an interracial marriage with a black woman, in "The Jeffersons."

He and his wife lived in the same "deluxe apartment building" that Sherman Hemsley moved his family to after making money in the dry-cleaning business. There, Cover often played a comic foil to Hemsley's blustering, opinionated black businessman. The show ran from 1975 to 1985.

Cover also appeared in several films, including "The Great Gatsby," "The Stepford Wives" and "Wall Street."

He is survived by his widow, Mary, a son and a daughter.

Barry Manilow's New Album Opens at No. 1

Barry Manilow's New Album Opens at No. 1

By Associated Press
Fri Feb 10, 9:29 AM

NEW YORK - Barry Manilow has landed on the top of the charts with a just-released album for the first time in 29 years. Manilow's "The Greatest Songs of the Fifties," debuted at No. 1 on the Billboard 200 chart, followed by Mary J. Blige's "The Breakthrough" and Andrea Bocelli's "Amore."

The album, 13 standards such as "Are You Lonesome Tonight?" and "Unchained Melody," has sold more than 156,000 copies in the United States since it arrived Jan. 31st.

His previous debut chart-topper was the 1977 concert recording, "Live." His last album, "Scores: Songs From Copacabana and Harmony," had a weak debut in 2004, peaking at No. 47.

Manilow, 62, said he was inspired to sing the 1950s pop classics because he feels they deserve more attention.

"The reason I connected with it is when I looked at the list of songs that came out of the '50s, it seemed to me that they had been neglected," he told Associated Press Television.

"Nobody seems to have done `Unchained Melody' or `It's Not for Me to Say' or `Beyond the Sea,' any of these songs that were wonderfully written that came out of the '50s. So that turned me on. I dove in."

Adult Stem Cell Research Overwhelmingly Beats Human Embryonic In Scientific Race


Diseases Treated with Stem Cells

Stem cell transplants have been used since the 1960’s to treat a variety of diseases. In 1988 cord blood stem cells were used for the first time in hematopoietic (blood) stem cell transplantation. Umbilical cord blood stem cells have now been used in over 3,500 transplants worldwide as a valuable alternative to traditional sources of hematopoietic stem cells. Utilizing the process of stem cell banking, cord blood stem cells also show great promise for potential future applications including treatment and repair of non-hematopoietic tissues, gene therapies, mini-transplants, among others.

A localized retinoblastoma of the left eye in a 7-year-old girl, was treated by enucleation. She received no additional therapy. Four months later, metastases of retinoblastoma in the lymph nodes, bone and bone marrow were diagnosed. Relapse chemotherapy consisting of three courses of vincristine, cyclophosphamide, etoposide and carboplatin led to a second complete remission. Subsequent high-dose chemotherapy with thiotepa, etoposide and carboplatin and autologous stem cell transplantation with CD34-selected stem cells were successful, with no
adverse effects. No radiotherapy was given and the girl remains in continuous second
remission with a follow-up of more than 4 years.

Umbilical Cord Blood Effective At Treating Adult Blood Disorders
A new report shows that umbilical cord blood can provide effective treatment of various blood disorders in adults. It had previously been assumed that there were too few stem cells in cord blood to treat adults, and only children were treated. The results of this study show that cord blood stem cells can proliferate extensively and provide sufficient numbers of cells for adult treatments.

This retrospective study included 21 children with acute lymphoblastic leukaemia, 15 with acute myelogenous leukaemia and one each with chronic myelogenous leukaemia, refractory anaemia with myelodysplastic syndrome (MDS) and juvenile myelomonocytic leukaemia (JMML). These data confirm that HLA-mismatched, unrelated Cord Blood Transplant is a feasible procedure to cure a significant proportion of children with leukaemia, especially if conducted in a favourable phase of the disease.

Angioimmunoblastic lymphadenopathy with dysproteinemia (or dysgammaglobulinemia) (AILD) is a lymphoproliferative disorder with abnormalities characteristic of malignant T-cell lymphoma (angioimmunoblastic T-cell lymphoma -- AITL). We report the clinical course of a 58-year-old male patient with unusually aggressive AILD, At relapse, treatment with high-dose chemotherapy followed by autologous peripheral stem cell transplantation (APSCT) with CD34 selected cells was shown to be successful. The patient is alive and disease-free 3 years after diagnosis and 32 months after APSCT. Considering the poor prognosis of the majority of patients with AILD, intensive treatment followed by APSCT, may be a subject for further studies.

Patients given high-dose chemotherapy followed by allogeneic stem cell transplants. Peripheral blood stem cells rather than bone marrow results in higher rates of overall and disease- free survival, and restores blood counts faster. Patients in whom the benefit of peripheral-blood cells was most apparent were those with advanced hematologic cancer. Other studies have also shown that the use of peripheral-blood cells is associated with fewer days of hospitalization and lower overall costs.

“Actuarial survival and disease-free survival at 34 months are 56% and 50% respectively, with 95% confidence interval (25-78%).These results suggest that nonmyeloablative conditioning significantly reduces transplant-related toxicity, thus making a second transplant feasible.”

Review of autologous stem cell treatment strategies. “Controlled clinical trials have demonstrated a long-term disease- free survival of 40%-50% for patients treated with at least two courses of HIDAC. Other studies have demonstrated that postremission autologous bone marrow transplantation results in a disease-free survival equal to or better than conventional chemotherapy. However, autotransplantation with mobilized peripheral blood stem cells (PBSC) would now be preferred instead of autologous bone marrow, due to the shorter hematopoietic reconstitution period.”

There are striking differences in the prognosis of patients with progressive HD and aggressive NHL. The prognosis of progressive NHL patients is dismal. Most patients have rapidly progressive disease after salvage treatment and are, therefore, excluded from HDCT programs. In contrast, progressive HD patients can achieve long-term survival after HDCT.”

Adult Stem Cells Treat Potentially Fatal Skin Disorder
A man with scleromyxedema, a rare and potentially fatal skin disease, is reported free of symptoms after receiving a transplant of adult stem cells taken from his own bone marrow. Like scleroderma, scleromyxedema causes the skin to thicken and become hard. Prior to the adult stem cell treatment, the patient could not completely close his eyes, and had lost the ability to eat. Three months after treatment the patient could once again close his eyes and open his mouth to eat. The results are reported in the August issue of Archives of Dermatology.

Adult Stem Cells Show Success in Treating Another Autoimmune Disease—Crohn’s Disease
Physicians at Chicago's Northwestern Memorial Hospital report initial success in using adult stem cells to treat two patients with Crohn's disease, a potentially disabling inflammatory bowel disease. One patient was said to be doing "phenomenally well" 2 ½ months after undergoing the procedure using the adult stem cells, which were extracted from her blood, leading doctors to try it on a second patient. Results in both patients were very encouraging, according to Dr. Richard Burt, who performed the procedures. Burt noted that results of similar procedures on multiple sclerosis patients have also shown progress, and that adult stem cell therapy on patients with lupus had repaired damage to their organs. According to Burt: " 'If you're able to use your own stem cells,' the embryonic stem cell issue is 'not just ethically moot, it's practically moot.' "
"Adult Stem Cells Hold Hope for Autoimmune Patients," Reuters Health, Aug. 13, 2001.

High-dose chemotherapy followed by autologous HSCT is feasible and safe, and can result in longterm improvement of disease activity in patients whose condition previously did not respond to conventional antirheumatic drugs or TNF blocking agents. The persistence of active disease in some patients may reflect the heterogeneity of the underlying disease process.

“Autoimmune diseases that are resistant to conventional treatment cause severe morbidity and even mortality. In the present study we demonstrate that complete remissions can be achieved in refractory polychondritis and systemic lupus erythematosus (SLE), even at advanced stage, with the use of autologous stem-cell transplantation (SCT). Remissions persisted after reconstitution of the immune system. In the treatment of advanced systemic sclerosis (SSc), stable disease may be achieved with autologous SCT.”

Nineteen patients (14 female, 5 male) with severe autoimmune diseases were treated. Nine had a rheumatologic disorder (5 juvenile chronic arthritis, 1 rheumatoid arthritis, 1 systemic vasculitis, 1 Sjogren's syndrome, 1 Behct's disease), 4 a neurologic disorder (3 multiple sclerosis, 1 myasthenia), 3 a haematologic disease (2 pure red cell aplasia, 1 autoimmune thrombocytopenia), 2 had a gastrointestinal disease (1 Crohn's disease, 1 autoimmune enteropathy) and 1 had a multiple autoimmune disorder. There was no regimen-related toxicity and no opportunistic infections occurred. Ninety percent of the patients improved and/or had a complete remission after the procedure. Fifty percent of the subjects went into complete or partial remission after a median follow-up of 15 months. A non- myeloablative conditioning regimen was able to induce persistent remission in some patients with severe autoimmune diseases. There was no mortality or morbidity related to the procedure. The extent of remission remains to be established.

Allogeneic peripheral blood stem cell transplantation (PBSCT) is rarely applied for the treatment of severe aplastic anemia (SAA) because of questionable durability of engraftment and increased risk of graft versus host disease (GVHD). We performed allogeneic PBSCT in 3 SAA patients from their human leukocyte antigen (HLA)- identical siblings. In 2 cases, no graft failure has been observed, and a successful and complete hematological recovery was achieved and maintained for 28 and 25 months, respectively. In conclusion, PBSCT provides a quick and complete hematological recovery in SAA patients.

Cartilage and Bone Diseases

Biopsies removed from 57 patients considered for cartilage transplantation were grown. Explant cultures allowed cell number expansion. Fifty- four out of 57 biopsies grew cells. Fanning out of the cells began after 5-15 days in culture. Two passages later, cell numbers in the 10(7) range were achieved. Explants of articular chondrocytes cultured in vitro consistently yield monolayer cultures. The cells appear to revert to dedifferentiated chondrocytes, expressing a mesenchymal stem cell protein profile. Simultaneously, these cells regained their capacity to proliferate.

Confluent sheets of cultured corneal epithelial cells, suitable for grafting, can be produced from limbal tissue taken from eye bank organ-cultured corneas, although it takes longer, on average, to reach confluence (17–21 days) than an equivalent sample from a fresh eye (9–12 days).
James SE et al.; “The Potential for Eye Bank Limbal Rings to Generate Cultured Corneal Epithelial Allografts”; Cornea 20, 488-494; July 2001

Fifteen of 16 eyes (93.7%) achieved epithelialization with a mean time to epithelial healing of 15.2 days. The only eye that failed to heal was subsequently diagnosed with total limbal stem cell deficiency. Visual acuity improved in five of nine (44%) sighted eyes. No patient experienced any major surgical or medical complication after the procedure. Amniotic membrane transplantation represents a safe and effective method to restore a stable corneal epithelium in eyes after primary surgical removal of band keratopathy arising from ocular causes.
Anderson DF et al.; “Amniotic Membrane Transplantation After the Primary Surgical
Management of Band Keratopathy”; Cornea 20(4), 354-361; May 2001

Amniotic membrane transplantation appears to be a safe and effective method of restoring a stable corneal epithelium for cases of partial limbal stem cell deficiency and can be considered as an alternative to limbal autograft or allograft. 17 eyes of 15 patients; All eyes exhibited a stable, intact corneal epithelial surface after a mean follow up period of 25.8 months with no eyes developing recurrent erosion or persistent epithelial defect. The mean time to re-epithelialisation was 22.8 days. Overall improvement in visual acuity was observed in 92.9% of 14 eyes with visual potential.
Anderson DF et al.; “Amniotic membrane transplantation for partial limbal stem cell
deficiency”; Br J Ophthalmol 85(5), 567-575; May 2001

An objective long term benefit from the procedure (improved Snellen acuity, reduced frequency of epithelial defects, reduced vascularisation, and scarring) was recorded for four out of five patients. Some subjective benefit was also reported. However, in no instances were donor cells recovered from the ocular surface at 3-5 years post-graft. Initial experiments to examine sensitivity indicated that any surviving donor cells must have constituted less than 2.5% of cells sampled. Limbal stem cell allotransplantation can provide long term benefits, as measured by objective criteria. However, such benefits do not necessarily correlate with survival of
measurable numbers of donor cells on the ocular surface.

Adult Stem Cells Used to Grow New Corneas
Researchers in the United States and Taiwan have used corneal adult stem cells to grow new corneas for patients with previously untreatable eye damage. Adult stem cells were taken from the patients themselves in 16 cases, or a family member for 4 other patients. The cells were then grown in culture before transplantation onto the damaged eyes. Sixteen of the 20 patients had improved vision. Dr. Ivan Schwab, professor of ophthalmology at the University of California at Davis Medical School, leader of the U.S. team, said “We think this is the beginning of a very exciting change in terms of how we manage surface disease of many kinds, not just in the eye.”

Stem Cell- Rich Cord Blood Successfully Treats Often Fatal Blood Disorder
In a joint statement, doctors at Singapore's National Hospital and Singapore General Hospital announced a "medical first" in transplanting umbilical cord blood from a non-related donor to successfully treat thalassaemia. Thalassaemia is a hereditary blood disorder that often causes severe anemia and is usually fatal to children if untreated. The statement noted that umbilical cord blood is rich in "haemopoietic stem cells" from which the different types of blood cells evolve.

Successful treatment of heart disease using adult stem cells
Doctors in Germany reported the successful use of a patient’s own adult stem cells from bone marrow for regenerating tissue damaged after a heart attack. They injected the man’s own bone marrow stem cells into his damaged heart muscle. Ten weeks after treatment, the damaged area of heart tissue had been reduced, replaced by new cells, and the function of the patient’s heart had increased by 20-30 %. The authors note that their results demonstrate that “transplantation of human autologous adult stem cells is possible under clinical conditions and that it can lead to regeneration of the myocardial scar after… infarction.” They also point out that the therapeutic
benefits can be ascribed to the adult stem cells. They plan to perform the same operation on 20 more patients in the coming months. The use of the patient’s own adult stem cells from bone marrow or muscle to treat damage from heart attack is also in clinical trials in France and the U.S. (Reuters Health, July 23, 2001)

First successful human stem cell treatment for heart disease uses adult stem cells
The first reports of successful treatment for heart disease using the patient’s own adult muscle stem cells are encouraging news regarding therapy after heart attack. French physicians implanted skeletal muscle stem cells back into the patient; the encouraging result after eight months’ follow- up underlines the potential of this new approach using adult stem cells. Further clinical trials are now underway in Europe and the U.S. for other patients with heart disease. No embryonic stem cells have ever been reported to be used in human trials. A review of potential heart treatments notes that cell transplantation is a potential therapeutic approach for patients with chronic heart failure. Experimental transplantation of muscle cells showed that the grafted cells can functionally integrate with and augment the function of the recipient heart. The scientists note that skeletal stem cells are abundant and can be grafted successfully into the animal’s own heart even after genetic manipulation in vitro.

General References Related to Clinical Uses of Adult Stem Cells
Recent studies have revealed that much of this remarkable developmental potential of embryonic stem cells is retained by small populations of cells within most tissues in the adult. Intercellular signals that control the proliferation, differentiation and survival of stem cells are being identified and include a diverse array of growth factors, cytokines and cell adhesion molecules. Intracellular mechanisms that regulate stem cell fate are also emerging and include established second messenger pathways, novel transcription factors and telomerase. The possibility that a decline in the numbers or plasticity of stem cell populations contributes to aging and age-related disease is suggested by recent findings. The remarkable plasticity of stem cells suggests that endogenous or transplanted stem cells can be 'tweaked' in ways that will allow them to replace lost or dysfunctional cell populations in diseases ranging from neurodegenerative and hematopoietic disorders to diabetes and cardiovascular disease.

Mesenchymal stem cells (MSCs) are the first non-hematopoietic progenitors to be isolated from the bone marrow and extensively characterized. In addition to their ability to support hematopoiesis, MSCs can differentiate into osteocytes, chondrocytes, tenocytes, adipocytes and smooth muscle cells. This article will review our current understanding of bone marrow stroma and MSCs and their potential therapeutic role in the setting of hematopoietic stem cell transplantation.

It appears that basal haematopoiesis is maintained throughout life, yet, the capacity to cope with haematological stress is decreased in advanced age. In principle, stem cells derived from aged donors can be used for autologous transplantation, when needed to recover basic haematopoiesis. Current methods for expansion and maintenance of stem cells in vitro enable examination of stem cell potential for long-term expansion and function. Understanding of the mechanisms underlying these processes will enable the fidelity of stem cell expansion and maintenance of their potential for long-term function.

This study examined whether cryopreservation following expansion has a detrimental effect on the ability of cells to engraft, using the NOD-SCID mouse model. Cord blood (CB) CD34(+) cells were incubated for 7 days with stem cell factor (SCF), flt-3 ligand (FL), and megakaryocyte growth and development factor (MGDF). Expanded CD34(+) cells were transplanted into NOD-SCID mice either fresh or following cryopreservation and thawing. Thawed expanded CD34(+) cells had significantly higher SCID Engrafting Potential (SEP) than freshly expanded CD34(+) cells. Results suggest that prior cryopreservation does not prevent expanded cells engrafting in NOD-SCID mice.

General review of growth factors using in hematopoietic stem cell transplants. Recently, EPO has been shown to significantly accelerate hematopoietic reconstitution after peripheral blood stem cell transplantation (PBSCT) resulting in reduced infection rates. Both, GCSF and GM-CSF have been shown, in numerous trials, to shorten the period of chemotherapy-induced neutropenia, with reduction in attendant morbidity and to mobilize PBSC. In addition, administration of both cytokines after PBSCT significantly reduced the use of antibiotics and duration of hospitalization suggesting an economic benefit.

Treating Parkinson’s with Adult Stems Cell and Other Alternatives

Using adult neural stem cells, Dr. Michel Levesque, at the Cedars-Sinai Medical Center in Los Angeles, reports a total reversal of symptoms in the first Parkinson’s patient treated. The patient, a 57-year old former fighter pilot, is still without symptoms three years after the adult neural stem cells were removed from his brain, coaxed into becoming dopamine-producing cells, and then reimplanted. Because the stem cells came from the patient, there was no need for immunosuppression to overcome rejection. "I think transplantation of the patient's own neural stem cells and differentiated dopaminergic neurons is more biologically and physiologically compatible - more efficacious and more elegant," said Levesque. In addition to its use for Parkinson’s, the technique is under study for juvenile diabetes, stroke, brain tumors, spinal cord injury, and other conditions.
Results presented April 8th, at the meeting of the American Association of Neurological Surgeons.

Retinal Cell Implants Improve Parkinson’s
A team at Emory University School of Medicine has shown that implanting retinal cells into the brains of people with advanced Parkinson's disease can improve motor function by almost half, according to a follow-up study of six patients. The team noted: "We've been following these six participants for over a year, and we've found they've improved, on average, nearly 50 per cent in motor function." The retinal cells used were taken from deceased donors and grown in the lab. The team is not using immunosuppressants.
Result presented April 18 at the annual conference of the American Academy of Neurology in Denver and reported in the New Scientist , April 18, 2002.

N.B: There are no clinical treatments for Parkinson’s based on cloning or embryonic stem cells.

Adult Skin Cells Reprogrammed Without Cloning
A team of scientists from Norway has succeeded in coaxing one type of adult cell to start behaving like a completely different type of adult cell. The scientists have made human skin cells in a test tube behave as if they were immune system cells, by bathing the skin cells in extracts of the immune cells. In other work, they have been able to get skin cells to behave as if they were nerve cells.
"We can take a skin cell from your body and turn it directly into a cell type that you need to treat a particular disease," said Dr. Philippe Collas, the leader of the team, whose work was published 5/1/02 in the respected journal Nature Biotechnology.

The technique being developed would allow skin cells from a patient to be turned directly into other types of cells without having to revert first to an embryonic state and without needing women's eggs. They told Reuters, "That's the beauty of our system -- we are not working with embryos or dealing with stem cells at all. You get around all these issues." "It would be a one-day procedure, in principal. The patient would come in and give a skin biopsy to the lab to reprogram and the day after you could put the cells back into the patient." The technique would have immediate applications in cancer. The group is also looking at making insulin-secreting pancreatic cells.

The approach will aid investigation of the mechanisms by which adult stem cells revert to cells capable of differentiating into other types of cells with potential use in therapies for conditions like diabetes, Parkinson's disease, and heart disease. From a clinical perspective, approaches based on this technology would allow replacement cells to be generated that are compatible with a patient's immune system, without the ethical problems of generating or destroying embryos.

Adult Bone Marrow Stem Cells Transformed Into Functional Liver Cells
Dr. Catherine Verfaillie’s group at Minnesota continues to show more and more uses for the multipotent adult progenitor cells (MAPC) from bone marrow. The team has now shown that these adult stem cells can transform into functional liver cells. The adult stem cells also were grown in culture for over 100 generations, twice the length of time previously thought possible with adult cells.

“Therapeutic” Cloning No Longer Needed, Says Leading Embryonic Stem Cell Scientist
Alan Trounson, Australian embryonic stem cell expert and a leader in the field worldwide, says that stem cell research (both adult and embryonic) has advanced so rapidly in the past few months that therapeutic cloning is now unnecessary. “My view is there are at least three or four other alternatives that are more attractive already,” he said. Professor Trounson said therapeutic cloning faces logistical problems, and that other techniques are showing great promise and offer better options.

Adult Stem Cells More Effective Than Embryonic Stem Cells in Blood Formation
Because hematopoietic (blood forming) stem cells (HSCs) can restore and maintain blood formation following transplantation into immune deficient hosts, growth of HSCs in culture is important for many clinical applications. Previously, researchers in Sweden used a gene therapy technique to add a growth gene to embryonic stem cells to get adequate growth in culture. According to the authors, however, “HSCs of early embryonic origin, including those derived from differentiated embryonic stem cells, are inefficient in engrafting adult recipients upon transplantation.” The researchers have now shown that adding the same growth gene, Lhx2, to adult bone marrow stem cells allows unlimited growth of the cells. These adult stem cells efficiently rescued immune-compromised mice and generated all blood cells.

Adult Bone Marrow Stem Cells Show Immune Tolerance, Not Rejected
Researchers in Canada and Japan have shown in animal studies that adult stem cells from bone marrow have a unique immunity tolerance. When selected bone marrow stem cells of mice were injected into rats, without immunosuppression, the injected cells survived and thrived without being rejected by the host immune system. The cells incorporated not only into bone marrow but also into damaged heart to aid repair.

Adult stem cells stimulated to form insulin-secreting pancreatic cells
Scientists at Massachusetts General Hospital have successfully turned adult stem cells into insulin-producing cells that could reverse diabetes. They found that treating adult stem cells in the pancreas with a naturally occurring hormone can transform the stem cells into beta cells, which secrete insulin. This means new beta cells could be made from a patient’s own pancreatic stem cells to treat their diabetes.

Adult Bone Marrow Stem Cells Can Repair Retina
Adult bone marrow stem cells injected into the eyes of rats with damaged retinas formed new retinal cells. The bone marrow stem cells incorporated and differentiated into retinal neural cells in the injured retina. Bone marrow stem cells may be useful in repair of damaged retinal cells.

Adult Bone Marrow Stem Cells Could Prevent Blindness, Grow New Blood Vessels
Scientists at Scripps Research Institute used bone marrow stem cells to grow new blood vessels in the eyes of mice, a development researchers say could lead to treatments for some forms of blindness in humans, including diabetic retinopathy and macular degeneration. The injected adult stem cells homed in on the parts of the eye where they were needed, grew new blood vessels, and prevented blindness in the mice. Diabetic retinopathy is the leading cause of blindness in working age Americans, and age-related macular degeneration is a common cause of vision loss in people over age 60. Both conditions are caused by damaged retinal blood vessels.

Adult Bone Marrow Stem Cells Stimulate Growth in Children With Bone Disease
Adult bone marrow stem cells implanted into children with osteogenesis imperfecta, a severe bone and cartilage disease, have stimulated growth of bone in these patients. During the 6 months immediately following the transplant, the children’s growth reached 60% to 94% of expected normal values for children their age.

Let’s Be Adult About This
Politics can be free of embryonic entanglements.


O nce upon a time, you were an embryo. Had researchers “harvested” your stem cells, you never would have learned to read or kissed your mom and dad good night. Indeed, you never would have been born, and your life would have been squandered for nothing. Embryonic stem-cell research has yet to produce a single cure, while adult stem-cell research already treats 65 diseases and benefits human patients, not just lab rats.

Embryonic-stem-cell research (ESCR) suffered a severe blow last month as one of its most promising proponents, South Korean researcher Hwang Woo-Suk, turned out to be a monumental fraud. The stem-cell lines he claimed to have created from cloned human embryos now have been exposed as utter fabrications. Donald Kennedy, editor of the journal Science has ordered “an immediate and unconditional retraction” of two papers in which Dr. Hwang discussed these bogus stem cells. Hwang — who had credited his earlier “successes” to “his workers’ dexterity with chopsticks,” the Associated Press reports — has resigned from Seoul National University with his reputation and “work” in tatters.

For the broader ESCR community, Hwang’s phony findings are akin to learning in 1879 that Thomas Edison’s light bulb was made of nothing more than candles, mirrors, and lies.

“The bottom line is that it’s a major disaster for our whole field,” Israeli researcher Joseph Itskovitz told the Associated Press, adding: “Now we are back to square one.”

For these reasons, among others, Congress, should abandon its foolish quest to use taxpayer dollars to dissect embryos.

Impracticality aside, this technology is bathed in moral problems. ESCR fatally divides microscopic humans (or at least pre-humans) into clumps of cells. The cells that would have been some child’s gleaming eyes some day might help make Alzheimer’s a memory. But that kid would not be here to see that happen.

Harvard scientists on August 22 announced a technique to make adult cells mimic embryonic cells without harming the latter. This eventually may do wonders. However, “Our technology is not ready for prime time yet,” assistant professor Kevin Eggan told the Boston Globe. “Our results do not offer an alternative now.”

Thankfully, medical innovation does not require Frankencells to be created by destroying Microscopic Americans. The Coalition of Americans for Research Ethics in Washington and Comment on Reproductive Ethics in London are among the organizations trumpeting the triumphs of embryo-free alternatives

* Since 1993, 1,801 individuals have received stem-cell-rich umbilical-cord blood from New York Blood Center alone. These have included 66 with lymphoma and 1,150 leukemia patients. NYBC supplies non-embryonic cord blood to 90 transplant facilities across America and 86 overseas.

* “I haven’t felt better in myself for 30 years,” Englishman Richard Lane told London’s Guardian newspaper last March. “I have to pinch myself to ensure I am not dreaming.” After receiving three transplants of normal pancreatic islet cells from a deceased donor, Lane’s type-1 diabetes stopped, as did his insulin injections. “It’s almost like being a totally different person,” he said. According to King’s College Hospital professor Stephanie Amiel, “Eventually this could mean the end of insulin dependence for all type-1 diabetes sufferers.”

The Lancet, a British medical journal, reported last April on a 56-year-old Japanese mother whose donated pancreatic islet cells have healed her 27-year-old daughter’s insulin-dependent diabetes.

* The August 2004 Lancet discussed the replacement of a German mouth-cancer patient’s removed jawbone. Using his own stem cells, doctors spent seven weeks growing him a new mandible around wire mesh. Once implanted, he tested it by biting into a Frankfurter. He soon resumed eating normally.

* Adult stem cells have helped some 60 paraplegics and quadriplegics regain sensation and movement. Stem cells from their own nasal cavities helped spinal-injury victims Laura Dominguez, Susan Fajt, and Erica Nader stand up and walk with braces.

“I am now preparing to shed the shell of this wheelchair,” Fajt told the Senate Science, Technology, and Space Subcommittee on July 14, 2004. “This is something my doctors in America told me would never be possible with my level of injury and to accept my fate.” Americans Dominguez, Fajt, and Nader have advanced under the care of Dr. Carlos Lima in Lisbon, Portugal.

Similar treatments empowered six Russians to boost their mobility. Bedridden for 19 years, South Korea’s Hwang Mi-Soon stepped gingerly with a walker one month after doctors injected cord blood into her damaged spine. “This is already a miracle for me,” she said in the November 30, 2004 London Daily Telegraph.

* Blind people now can see, thanks to doctors who extract stem cells from patients’ own eyes, then culture healthy tissue to repair their corneas. “I feel like a human being again,” Deborah Catlyn told the Telegraph last April. She regained her sight after losing it in 2002 when a woman at a nightclub threw acid in her face. Catlyn is one of 20 Britons who this adult-stem-cell-research procedure has enriched. It was developed at Hyderabad, India’s Prasad Eye Institute, where some 200 blind people have been treated, most of them successfully.

Adult-stem-cell and cord-blood successes render inexcusable congressional efforts to fund embryonic-stem-cell research. With dilemma-free treatments already curing patients, why on Earth did the GOP House of Representatives last May 24 vote 238-194 to approve federal funds to slice tiny boys and girls into laboratory specimens? Before bumbling into his own insider-trading probe, Senate Majority Leader Bill Frist, M.D., of Tennessee enraged many fellow Republicans by flip-flopping and endorsing the same ESCR legislation he previously opposed and President Bush justifiably promises to veto. Republicans have no business initiating subsidies for homicidal medical research. For now, pharmaceutical companies remain free to finance this activity, if they must.

When it comes up for a vote, the U.S. Senate should defeat this measure and let adult stem cells work their magic. Taxpayers should not be forced to sponsor the destruction of Microscopic Americans, especially when “surplus” embryos are being adopted, implanted, and are being born alive as so-called "Snowflakes" babies — 99 of them so far. Washington should let these souls on ice live happily ever after.

EFF FAQ: The Foreign Intelligence Surveillance Act (FISA)


Prepared by Lee Tien, Electronic Frontier Foundation Senior Counsel, Sep. 27, 2001

1. What is FISA?

FISA is the Foreign Intelligence Surveillance Act, which establishes a legal regime for "foreign intelligence" surveillance separate from ordinary law enforcement surveillance. Foreign Intelligence Surveillance Act of 1978, Pub. L. No. 95- 511, 92 Stat. 1783 (codified as amended at 50 U.S.C. §§ 1801-1811, 1821-1829, 1841-1846, 1861-62).

2. What is the purpose of FISA?

FISA is aimed at regulating the collection of "foreign intelligence" information in furtherance of U.S. counterintelligence, whether or not any laws were or will be broken. See 50 U.S.C. § 401(a)(3) (defining "counterintelligence" as information gathered and activities conducted to protect against espionage, other intelligence activities, sabotage, or assassinations conducted by or on behalf of foreign governments or elements thereof, foreign organizations, or foreign persons, or international terrorist activities). Department of Defense (DOD) guidelines state that the purpose of counterintelligence collection is to detect espionage, sabotage, terrorism, and related hostile intelligence activities to "deter, to neutralize, or to exploit them."

In short, counterintelligence and criminal prosecution are different.

3. How does FISA fit with regulation of electronic surveillance?

Given the "tendency of those who execute the criminal laws . . . to obtain conviction by means of unlawful seizures," the Supreme Court has viewed commumications interception as an especially grave intrusion on rights of privacy and speech. Berger v. New York, 388 U.S. 41, 50 (1967) (quotation and citation omitted). "By its very nature eavesdropping involves an intrusion on privacy that is broad in scope," and its "indiscriminate use . . . in law enforcement raises grave constitutional questions." Id. at 56 (quotation and citation omitted). "Few threats to liberty exist which are greater than those posed by the use of eavesdropping devices." Id. at 63.

Thus, the Court outlined seven constitutional requirements: (1) a showing of probable cause that a particular offense has been or is about to be committed; (2) the applicant must describe with particularity the conversations to be intercepted; (3) the surveillance must be for a specific, limited period of time in order to minimize the invasion of privacy (the N.Y. law authorized two months of surveillance at a time); (4) there must be continuing probable cause showings for the surveillance to continue beyond the original termination date; (5) the surveillance must end once the conversation sought is seized; (6) notice must be given unless there is an adequate showing of exigency; and (7) a return on the warrant is required so that the court may oversee and limit the use of the intercepted conversations.

Indeed, the Court said that if "neither a warrant nor a statute authorizing eavesdropping can be drawn so as to meet the Fourth Amendment's requirements . . . then the Ôfruits' of eavesdropping devices are barred under the Amendment." Id., at 63.

Where intelligence operations are concerned, however, the bounds of the Fourth Amendment are less clear than they are for ordinary criminal investigations. FISA creates a special court and legal regime for counterintelligence surveillance orders.

Executive Order 12,333 (1981) provides the general framework for U.S. intelligence activities, and it also addresses electronic surveillance. "[A]gencies are not authorized to use such techniques as electronic surveillance, unconsented physical searches, mail surveillance, physical surveillance, or monitoring devices unless they are in accordance with procedures established by the head of the agency concerned and approved by the Attorney General." EO 12,333, para. 2.4. Dep't. of Defense (DOD) Directive 5240.1-R implements FISA and EO 12,333 within DOD. These authorities govern the collection of intelligence by the U.S. government against United States persons, whether they are located within the United States or outside the United States.

FISA does not regulate the use of electronic surveillance outside of the United States. For instance, electronic surveillance of electronic communications like e-mail is only governed by §1801(f)(4) if the surveillance device is installed "in the United States." When e-mail sent by a U.S. person to a foreign person is intercepted outside the United States, that interception does not meet this definition.

4. Why is there a special legal regime for "foreign intelligence" surveillance?

The path to FISA has two branches, political and judicial.

The government had long maintained that it had extensive discretion to conduct wiretapping or physical searches in order to protect national security. In Katz v. United States, 389 U.S. 347 (1967), the Supreme Court acknowledged that the President had claimed special authority for warrantless surveillance in national security investigations, and explicitly declined to extend its holding to cases "involving the national security." Id. at 358 n. 23. Similarly, Congress in Title III stated that "nothing in Title III shall . . . be deemed to limit the constitutional power of the President to take such measures as he deems necessary to protect the United States against the overthrow of the Government by force or other unlawful means, or against any other clear and present danger to the structure or existence of the Government."

On the political front, such executive branch activities, charitably described as "some degree of domestic overreaching of intelligence into domestic areas," had long been tolerated. Staff of House Permanent Select Comm. on Intelligence, 104th Cong., Staff Study, IC21: Intelligence Community in the 21st Century at 272 (comm. print 1996).

But in the 1970s the political winds changed. The 1975-76 Church Committee hearings documented extraordinary federal government abuse of surveillance powers. Examples included the the NSA's Operation Shamrock and Operation Minaret, CIA's Operation CHAOS, the FBI's COINTELPRO domestic harassment of dissenters and anti-war protesters that included illegal wiretapping, and the illegal burglaries of the Nixon White House "plumbers."

The Church Committee Report found that covert action had been excessive, had circumvented the democratic process, and had violated the Constitution. It concluded that Congress needed to prescribe rules for intelligence activities.

On the judicial front, the Supreme Court first confronted the tension between unmonitored executive branch surveillance and civil liberties in United States v. U.S. District Court, 407 U.S. 297 (1972), in which the United States charged defendants with conspiracy to destroy government property. Defendants sought electronic surveillance information, held by the prosecution, that the CIA obtained during a potentially illegal wiretap, wanting to ascertain whether the government had relied on information in the indictment or the case for conviction and to suppress any tainted evidence at trial. The Attorney General admitted that a warrantless wiretap had intercepted conversations involving the defendants.

Before the Supreme Court, the government defended its actions on the basis of the Constitution and the Title III national security disclaimer. The Court rejected the statutory argument, saying that "Congress . . . simply did not legislate with respect to national security surveillances." As for the constitutional argument, the Court accepted that the President had the power "to protect our Government against those who would subvert or overthrow it by unlawful means" and that this power justified electronic surveillance of would-be subversives.

Invoking the "broader spirit" of the Fourth Amendment and "the convergence of First and Fourth Amendment values" in national security wiretapping cases, however, the Court was especially wary of possible abuses of the national security power. The Court then balanced "the duty of Government to protect the domestic security, and the potential danger posed by unreasonable surveillance to individual privacy and free expression," and found that waiving the Fourth Amendment probable cause requirement could lead the executive to "yield too readily to pressures to obtain incriminating evidence and overlook potential invasions of privacy and protected speech." Justice Powell wrote that the inconvenience to the government is "justified in a free society to protect constitutional values."

The Court emphasized that this case involved only the domestic aspects of national security: "We . . . express no opinion as to, the issues which may be involved with respect to activities of foreign powers or their agents." It invited Congress to act: "Given these potential distinctions between Title III criminal surveillances and those involving the domestic security, Congress may wish to consider protective standards for the latter which differ from those already prescribed for specified crimes in Title III. Different standards may be compatible with the Fourth Amendment if they are reasonable both in relation to the legitimate need of Government for intelligence information and the protected rights of our citizens."

These two paths, political and judicial, converged in the enactment of FISA.

5. Can FISA be used for ordinary criminal investigation?

Yes, but with qualifications. Under current law, any FISA investigation must have FII collection as its "primary purpose." Crossing the "primary purpose" line for information collection (from counterintelligence to law enforcement) subjects the investigation and evidence to extensive legal scrutiny and policy concerns. For instance, under DOD Dir. 5240.1-R, procedure 1, A, 3, DOD components cannot use the procedures for collecting intelligence information as a subterfuge for collecting evidence for a prosecutorial purpose.

This would change under draft Anti-Terrorism Act of 2001 (ATA).

6. Is there really a secret FISA court?

Yes. FISA established a special court, composed of seven federal district court judges appointed by the Chief Justice for staggered terms and are from different circuits. See 50 U.S.C.A. § 1803. Individual judges of the FISC review the Attorney General's applications for authorization of electronic surveillance aimed at obtaining foreign intelligence information. The proceedings are nonadversarial and are based solely on the DOJ's presentations through its Office of Intelligence Policy and Review.

The records and files of the cases are sealed and may not be revealed even to persons whose prosecutions are based on evidence obtained under FISA warrants, except to a limited degree set by district judges' rulings on motions to suppress. 50 U.S.C. §1803(c). There is no provision for the return of each executed warrant to the FISC, much less with an inventory of items taken, nor for certification that the surveillance was conducted according to the warrant and its "minimization" requirements.

The FISC meets two days monthly, and two of the judges are routinely available in the Washington, D.C. area on other days. Statement of Mary C. Lawton, Counsel for Intelligence Policy, Before the House Subcommittee on Courts, Civil Liberties, and the Administration of Justice, June 8, 1983, at 8.

7. What kind of surveillance can be authorized under FISA?

Originally, FISA was limited to electronic eavesdropping and wiretapping. 50 U.S.C. § 1801(f). In 1994 it was expanded to permit covert physical entries in connection with "security" investigations. 50 U.S.C. §§ 1821-1829. In 1998, it was amended to permit pen/trap orders, 50 U.S.C. §§ 1841-1846. FISA can also be used to obtain certain business records. §§ 1861-62.

8. How is surveillance authority different under FISA?

Although orders issued under FISA are sometimes called FISA "warrants," this is misleading because it suggests that the FISA order is like an ordinary search warrant or Title III intercept order -- and it isn't. Under the Fourth Amendment, a search warrant must be based on probable cause to believe that a crime has been or is being committed. This is not the general rule under FISA.

9. What is the basic "trigger" for permitting FISA surveillance?

Under FISA, surveillance is generally permitted based on a finding of probable cause that the surveillance target is a foreign power or an agent of a foreign power -- not whether criminality is in any way involved. §1801(b)(1).

10. What is a "foreign power"?

Examples of groups that would likely meet the definition of "foreign power" are the Irish Republican Army, Hezbollah, the PFLP, the ANC, and the FMLN. Note that a "foreign power" need not engage in activities hostile to U.S. interests.

A "foreign power" is

* a foreign government or a component thereof, whether or not recognized by the United States, 50 U.S.C. § 1801(a)(1).
* a "faction" of a foreign nation or nations, not substantially composed of United States persons, 50 U.S.C. § 1801(a)(2). The term "substantially" is not defined.
* any entity that a foreign government acknowledges it controls and directs, such as government trading or business corporations, § 1801(a)(3). It is unclear whether general regulation of a foreign corporation constitutes control and direction.
* any entity that in fact is controlled and directed by a foreign government. § 1801(a)(6). Given FISA's structure, it appears that this is decided by the FISA court.
* any group engaged in international terrorism or "activities in preparation therefor," not only governments or their components. § 1801(a)(4).
* any "foreign-based political organization, not substantially composed of United States persons." § 1801(a)(5). What do "foreign-based," "political," "organization," and "substantially" mean? Would FISA include a group of foreign college or graduate students that engages in political activism? A group of people who exchange opinions about world affairs by e-mail, some of whom live in the United States and others abroad?

11. What is an "agent of a foreign power"?

FISA §1801(b) defines this phrase in two ways, depending on whether the target is a U.S. person. §1801(b)(1) covers non-U.S. persons, while § 1801(b)(2) covers "any person."

Non-U.S. persons are "agents" under FISA if they

* act in the United States as an officer or employee of a foreign power, or as a member of a terrorist organization, § 1801(b)(1)(A)
* act for or on behalf of a foreign power that engages in clandestine intelligence activities in the United States contrary to U.S. interests when (1) the circumstances of such persons' presence in the United States "indicate that such person may engage in such activities, or (2) when such person knowingly aids or abets any person, or conspires with any person to engage in such activities." 50 U.S.C. § 1801(b)(1)(B).

So, for instance, a British national who works for the British embassy in the United States is an agent of a foreign power.

American citizens and permanent residents are "agents" if they knowingly engage in espionage for a foreign power or intelligence service, and such activities "are about to involve" a violation of U.S. laws--any criminal laws, not just espionage. §1801(b)(2)(B).

12. So FISA doesn't treat aliens and U.S. citizens equally?

If the target is a "U.S. person," which includes permanent resident aliens and associations and corporations substantially composed of U.S. citizens or permanent resident aliens, 50 U.S.C.A. § 1801(i), there must be probable cause to believe that the U.S. person's activities "may" or "are about to" involve a violation of the criminal statutes of the United States. § 1801(b)(2)(A),(B); see also § 1801(b)(2)(C) (knowingly engages in activities in preparation for sabotage or "international terrorism" on behalf of a foreign power); § 1801(b)(2)(D) (knowingly enters the United States under a false or fraudulent identity for or on behalf of a foreign power or, while in the United States, knowingly assumes a false or fraudulent identity for or on behalf of a foreign power).

A "United States person" may not be determined to be an agent of a foreign power "solely upon the basis of activities protected by the first amendment to the Constitution of the United States." 50 U.S.C. § 1805(a)(3)(A).

13. What is "foreign intelligence" information (FII)?

Under 50 U.S.C. §1801(e)(1), FII is information that "relates to" U.S. ability to protect against:

1. possible hostile acts of a foreign power or an agent of a foreign power,
2. sabotage or terrorism by a foreign power or agent, and
3. clandestine intelligence activities by a foreign power or agent.

FII includes information with respect to a foreign power or foreign territory that "relates to" the national defense, national security, or conduct of foreign affairs of the United States. § 1801(e)(2),

Under both sections, if the intended surveillance target is a U.S. person, the information must instead be "necessary to" U.S. self-protective ability or U.S. national defense, national security, or foreign affairs.

The difference between "relates to" and "necessary to" is undefined in the statute, although there may exist a secret FISA "case law."

Note that because the key FISA definitions are not tied to criminal conduct or even conspiracies, FISA can extend to FII in plain public view or in open archives (such as legal photographs of a city, a facility, or a public street, or newspaper clippings copied from a "morgue").

14. Can the FBI use FISA surveillance to get evidence for criminal prosecution?

FISA surveillances must have an intelligence purpose. 50 U.S.C. §1804 (a) (7)(B). But courts allow FISA-obtained information to be used in criminal trials. See, e.g., Exec. Order No. 12,333, 3 C.F.R. 200, 211 (1982), reprinted in 50 U.S.C. § 401 note (1994) (allowing the dissemination of information incidentally obtained during intelligence gathering that indicates activities potentially violating any law).

Courts that have allowed evidence gathered during the surveillance to support a criminal conviction have required that intelligence be the "primary" purpose of the surveillance. United States v. Humphrey, 456 F. Supp. 51 (E.D. Va. 1978), aff'd sub nom. United States v. Truong Dinh Hung, 629 F.2d 908, 913 (4th Cir. 1980), ("the Executive Branch need not always obtain a warrant for foreign intelligence surveillance"), cert. denied, 454 U.S. 1144 (1982); United States v. Megahey, 553 F. Supp. 1180, 1189-90 (E.D.N.Y. 1982), aff'd sub nom. United States v. Duggan, 743 F.2d 59 (2d Cir. 1984).

In the Megahey litigation, the district court found that the phrase "primary purpose" is the guidepost for FISA-derived surveillance, given that "Congress clearly viewed arrest and criminal prosecution as one of the possible outcomes of a foreign intelligence investigation." The Second Circuit agreed, noting that, it is foreseeable that collected intelligence may be used in a criminal proceeding and "Congress recognized that in many cases the concerns of government with respect for foreign intelligence will overlap with those with respect to law enforcement." See also United States v. Johnson, 952 F.2d 565, 572 (1st Cir. 1991) (holding that the fact that the terrorist activity was directed at Northern Ireland was of no consequence to the legality of the FISA surveillance); United States v. Pelton, 835 F.2d 1067, 1076 (4th Cir. 1987) (concluding that "FISA surveillance is not tainted simply because the government can anticipate that the fruits of the surveillance may later be used... in a criminal trial").

15. Why is FISA dangerous?

Most important, FISA powers are broad and vague, and the secrecy of FISA proceedings makes FISA powers susceptible to abuse.

FISA power extends well beyond spies and terrorists. It can be used in connection with ordinary criminal investigations involving United States citizens who live in this country and who may be charged with offenses such as narcotics violations or breaches of an employer's confidentiality. 50 U.S.C. §§ 1806, 1825.

For instance, electronic surveillance under § 1801(f)(1) only reaches wire or radio communications "sent by or intended to be received by a particular, known United States person who is in the United States, if the contents are acquired by intentionally targeting that United States person" and a warrant would ordinarily be required. If the U.S. person is not "known," or more important, not "intentionally" targeted, it simply isn't "electronic surveillance" under § 1801(f)(1).

Note also that FISA expressly contemplates that it will produce "unintentionally acquired information." § 1806(i). But while this section requires the destruction of such information, it only applies to "the contents of any radio communication," only if a warrant would have been required, and only if both the sender and intended recipients are within the United States.

Given these limits, one may presume that "unintentionally acquired information" outside these lines is not destroyed. That would include all "unintentionally acquired"wire or electronic communications.

16. How does FISA work?

Under FISA, requests for counterintelligence warrants are funneled through the Justice Department, which reviews applications by the CIA as well as other agencies before submitting them to the FISA court. 50 U.S.C. §§ 1804(a), 1822(a)(1) (1994). Each application to the FISA court must first be personally approved by the Attorney General. See 50 U.S.C. § 1804(a).

The application must contain, among other things,

a statement of reasons to believe that the target of the surveillance is a foreign power or agent of a foreign power, specified information on the implementation of the surveillance, and a "certification" from a high-ranking executive branch official stating that the official "deems the information sought to be foreign intelligence information" and that the information sought "cannot reasonably be obtained by normal investigative techniques."

See generally 50 U.S.C. §§ 1804(a)(7), 1805(a) (setting forth the findings necessary to support the issuance of an order authorizing surveillance).

Particular facts or representations required include: statements regarding all previous applications involving the target; "detailed description of the nature of the information sought and of the type of communication or activities to be subject to the surveillance," § 1804(a)(6); the length of time surveillance is required, § 1804(a)(10); whether physical entry into a premises is necessary, and proposed procedures to minimize the acquisition, use, and retention of information concerning nonconsenting U.S. persons. § 1804(b).

On the basis of the application, a FISC judge must find probable cause that the target is a foreign power or agent of a foreign power, and that the facilities where the surveillance is directed are or will be used by the target.

For U.S. persons, the FISC judge must find probable cause that one of four conditions has been met: (1) the target knowingly engages in clandestine intelligence activities on behalf of a foreign power which "may involve" a criminal law violation; (2) the target knowingly engages in other secret intelligence activities on behalf of a foreign power pursuant to the direction of an intelligence network and his activities involve or are about to involve criminal violations; (3) the target knowingly engages in sabotage or international terrorism or is preparing for such activities; or (4) the target knowingly aids or abets another who acts in one of the above ways.

Courts have attached conditions to the executive's use of warrantless surveillance, including the requirement that the President or Attorney General authorize the search, the search targets a foreign power or its agents, and the primary purpose of the search is to gather foreign intelligence information. See Exec. Order No. 12,333, § 2.5, 3 C.F.R. 200 (1982), reprinted in 50 U.S.C. § 401 note (1994) (requiring approval of attorney general for warrantless searches).

An order of the FISC may approve electronic surveillance of an agent of a foreign power for ninety days and of a foreign power for a year. Extensions may be granted on the same terms, except that targets who are foreign powers may be subject to surveillance for an additional year if there is probable cause to believe that no communication of any U.S. person will be acquired.

17. What happens if a criminal defendant challenges the validity of FISA surveillance?

Suppose a defendant moves to suppress evidence obtained via FISA surveillance. FISA provides that the district court must review in camera and ex parte the FISA application and other materials necessary to rule upon a defendant's suppression motion "if the Attorney General files an affidavit under oath that disclosure or an adversary hearing would harm the national security of the United States." 50 U.S.C. § 1806(f). See United States v. Belfield, 692 F.2d 141, 147 (D.C.Cir.1982) ("The language of section 1806(f) clearly anticipates that an ex parte, in camera determination is to be the rule. Disclosure and an adversary hearing are the exception, occurring only when necessary.").

In such circumstances, neither defendant nor defendant's counsel is likely to have access to the underlying information. 50 U.S.C. § 1806(f) (The district court "may disclose to the aggrieved person, under appropriate security procedures and protective orders, portions of the application, order, or other materials relating to the surveillance only where such disclosure is necessary to make an accurate determination of the legality of the surveillance.").

18. Does FISA authorize surveillance without a court order?

Yes. In general, the Justice Department may engage in electronic surveillance to collect FII without a court order for periods up to one year. 50 U.S.C. § 1802. There must be no "substantial likelihood" that the intercepted communications include those to which a U.S. person is a party. § 1802(a)(1)(B).

Such electronic surveillance must be certified by the Attorney General and then noticed to the Senate and House intelligence committees. § 1802(a)(2). A copy of the certification must be filed with the FISC, where it remains sealed unless (a) an application for a warrant with respect to it is filed, or (b) the legality of the surveillance is challenged in another federal district court under § 1806(f). § 1802(a)(3). Common carriers must assist in the surveillance and maintain its secrecy. § 1802(a)(4).

In emergencies, the Attorney General may authorize immediate surveillance but must "as soon as practicable, but not more than twenty-four hours" later, seek judicial review of the emergency application. § 1805(e).

19. Is FISA really constitutional?

Lower courts have found FISA constitutional. See e.g., United States v. Duggan, 743 F.2d 59(2d Cir. 1984); United States v. Belfield, 692 F.2d 141 (D.C.Cir 1982); United States v. Nicholson, 955 F.Supp. 588 (E.D. Va. 1997).

In United States v. U.S. District Court, the Supreme Court used a two-part Fourth Amendment reasonableness test. It is doubtful whether the FISA review process satisfies the Court's first measure of the reasonableness of warrantless surveillance -- whether the citizens' interest in privacy and free expression are better served by a warrant requirement.

The second element --whether a judicially imposed law enforcement warrant requirement would "unduly frustrate the efforts of Government to protect itself" -- may be more easily met in the foreign intelligence setting. But Title III has for more than 30 years required more stringent procedures for criminal investigatory wiretaps.
