On an animal-breeding farm in Siberia are cages housing two colonies of rats. In one colony, the rats have been bred for tameness in the hope of mimicking the mysterious process by which Neolithic farmers first domesticated an animal still kept today. When a visitor enters the room where the tame rats are kept, they poke their snouts through the bars to be petted.
The other colony of rats has been bred from exactly the same stock, but for aggressiveness instead. These animals are ferocious. When a visitor appears, the rats hurl themselves screaming toward their bars.
“Imagine the most evil supervillain and the nicest, sweetest cartoon animal, and that’s what these two strains of rat are like,” said Tecumseh Fitch, an animal behavior expert at the University of St. Andrews in Scotland who several years ago visited the rats at the farm, about six miles from Akademgorodok, near the Siberian city of Novosibirsk. Frank Albert, a graduate student at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, is working with both the tame and the hyperaggressive Siberian strains in the hope of understanding the genetic basis of their behavioral differences.
The two strains of rat are part of a remarkable experiment started in the former Soviet Union in 1959 by Dmitri K. Belyaev and his brother, who were geneticists who believed in Mendelian theory.Human self-domestication, if it occurred, would probably not have exactly the same genetic basis as tameness in animals. But Mr. Albert said that if he could pinpoint the genetic difference between the tame and ferocious rats, he would compare the chimp genome and the human genome to see if they showed a similar difference.
One possibility is that a handful of genes — perhaps even just one — underlie all the changes seen in domestication. A structure in the embryo of all vertebrates, known as the neural crest, is the source of cells that constitute much of the face, skull and pigment cells, and many parts of the peripheral nervous system and endocrine system. If the genes in the neural crest cells were delayed just a little in coming into action, a whole range of tissues could be affected, including the maturation of the adrenal glands that underlies the first fear response of young animals, Dr. Fitch has written.
Researchers at Columbia University are combining the processing power of the human brain with computer vision to develop a novel device that will allow people to search through images ten times faster than they can on their own.
The technology would allow hours of footage to be very quickly processed, so security officers could identify terrorists or other criminals caught on surveillance video much more efficiently.
The "cortically coupled computer vision system," known as C3 Vision, is the brainchild of professor Paul Sajda, director of the Laboratory for Intelligent Imaging and Neural Computing at Columbia University. He received a one-year, $758,000 grant from Darpa for the project in late 2005.
The system harnesses the brain's well-known ability to recognize an image much faster than the person can identify it.
"Our human visual system is the ultimate visual processor," says Sajda. "We are just trying to couple that with computer vision techniques to make searching through large volumes of imagery more efficient."
The brain emits a signal as soon as it sees something interesting, and that "aha" signal can be detected by an electroencephalogram, or EEG cap. While users sift through streaming images or video footage, the technology tags the images that elicit a signal, and ranks them in order of the strength of the neural signatures. Afterwards, the user can examine only the information that their brains identified as important, instead of wading through thousands of images.
In interviews, several experts said that although they did not know the details of the case, they suspected that it had to be more complicated than the “plain and simple homicide” asserted by the attorney general, Charles C. Foti.
One possibility is that the patients were suffering and the only way to keep them comfortable was with high drug doses that may, incidentally, have hastened their deaths. It is not known, though, how much the patients were suffering.
Charo, a professor of law and bioethics at the University of Wisconsin, said: “The real dilemma here is in getting at the very precise facts of the case. I can say that, as a general matter, if you have a patient who is in distress and who needs pain relief and if the only level of painkillers that will relieve the pain also poses a high risk of death then it is permissible to give the pain relievers, provided the patient has consented to the risk of death.”
Even if the patient can no longer give consent, Professor Charo said, it is still ethical for doctors to treat the pain if they believe it is what the patient would want.
“If that was the case, then this is not simple homicide, and I can only hope the investigators were attentive to this,” she said.
For Caplan, No. 1 on his list is whether suffering was involved. "So I want happy chickens, no veal, no foie gras. After that comes environmental impact, and then labor. I have an ethical guide in my head that helps me through the store."
He also points out that, in a way, we should be grateful we are even considering all these ethical questions. "These are the dilemmas of abundance," he says. "If we were living in Darfur, the only answer to 'what to eat?' would be 'anything I can find.' "
Blue Brain researchers say they believe the simulation will provide fundamental insights that can be applied by scientists who are trying to simulate brain functions. Researcher Robert Hecht-Nielsen is seeking to build an electronic butler called Chancellor that would be able to listen, speak and provide in-home concierge services. He contends that with adequate resources, he could create such a machine within five years. (ooh, wouldn't you like one of those?)
Attempts in Congress to override the veto, which would require a two-thirds vote, were expected to fail.
According to the Christian Science Monitor, analysts agree that President Bush's veto was risky but unavoidable. Since the issue of stem-cell research arose early in his presidency, when Mr. Bush approved federal funding of preexisting stem-cell lines, he has remained adamant that no federal monies be used on newer cell colonies. The president believes the killing of human embryos, from which stem cells are harvested, is murder, says press secretary Tony Snow.From R. Alta Charo just off the presses:
Rumor has it that the president's veto of the stem cell bill will take
place around 2 pm today.

Wallis showed few outward signs of consciousness, but his brain was methodically rebuilding the white-matter infrastructure necessary for him to interact with the outside world, researchers reported yesterday in the Journal of Clinical Investigation.
``I believe it's a very, very slow self-healing process of the brain," said Henning Voss, lead author of the study and a physicist at Weill Cornell Medical College's
Wallis emerged from a minimally conscious state in 2003 at the age of 39 and uttered his first word since Ronald W. Reagan was in the White House: ``Mom." Since then, the onetime mechanic from Big Flat, Ark., has regained the ability to form sentences and recovered some use of his limbs, though he still can't walk or feed himself.
Using both PETscans (Positron Emission Tomography scans) and an advanced imaging technique called diffusion tensor imaging, the researchers examined Wallis's brain after he regained full consciousness, and found that cells in the relatively undamaged areas had formed new axons, the long nerve fibers that transmit messages between neurons.
``In essence, Terry's brain may have been seeking out new pathways to reestablish functional connections to areas involved in speech and motor control -- to compensate for those lost due to damage," said the study's senior author, Dr. Nicholas Schiff, a neurologist at the Weill Cornell Medical College in New York.From guest blogger, Peter J.

Routine HIV testing in the District of Columbia
I have often wondered if blood samples taken for laboratory tests or during hospitalization are screened for human immunodeficiency virus (HIV). One could argue that routine screening of blood samples would be a good laboratory safety precaution; or that it could help catch infections in unsuspecting individuals, allowing early treatment and slowing the spread of the disease overall. A battery of questions flows: Could it also be argued that routine lab and hospital screening is too costly to be practical? Are there a set of guidelines for when HIV screening is performed? Are HIV screenings only performed when they must be ruled out as part of an explanation for a set of symptoms? Was my blood screened for HIV when I was hospitalized? Would I have been told only if my test was positive? Would routine hospital screening for HIV be considered a violation of privacy or other rights without patient consent?
Now the city of Washington, DC, which is believed to have the highest rate of HIV infection in the country (179.2/100,000 people), is urging mandatory HIV testing as part of routine health screening for all patients between the ages of 14 and 84. The Centers for Disease Control (CDC) has been pushing for physicians to routinely screen patients, but this is the first local effort of its kind. Starting tomorrow, the city will distribute 80,000 tests to community groups, doctors' offices, emergency rooms, and STD clinics. These are oral swab tests that produce results in twenty minutes, as opposed to blood tests that can take two weeks to process. According to Jason DeParle of the New York Times, this is "significant because many people who underwent the earlier tests never returned to learn the results, meaning those with the virus remained unaware of the risk they posed to others." I would take a guess that any test that can be processed in twenty minutes is also much less costly than one that gets sent to the lab for two weeks.
While the practicality of an oral test and the idea of routine testing potentially dissolve a few barriers toward HIV detection, there are still many questions to be addressed. Firstly, in a city of more than 550,000, how far will 80,000 tests go, and what happens when they run out? Susan Levine of the Washington Post reported on Saturday that the aim is to use up that supply by the end of the year, "which would mean reaching a fifth of their key population in the next six months." Both Patricia Nalls of the Women's Collective in Northwest Washington and Walter Smith of the DC Appleseed Center for Law and Justice expressed concerns about not having heard any detail about planning for necessary counseling and follow-up care for a newly diagnosed HIV-positive population.
It is also unclear as to whether routine screening does present a privacy issue. Alan Cross reported that the "recommendation met with some resistance from privacy advocates who felt that such a testing might end up stripping HIV-positive people of their privacy and a breach of confidentiality would make it difficult for them to lead normal lives."

Brain deposits of a small protein known as amyloid beta long have been associated with Alzheimer's. But scientists have been unable to determine whether the body begins producing too much of the protein or loses the ability to clear it away.
Now, a research team led by Dr. Randall J. Bateman at Washington University in St. Louis is poised to find that answer with a test that for the first time can monitor the protein.
An initial test of the new technique on six healthy volunteers determined that the protein is quickly produced and quickly cleared, keeping it in balance in the central nervous system, the researchers report in Monday's online issue of the journal Nature Medicine.

Imagine being able to order a genetic test over the Internet -- to see if you have inherited a predisposition to cancer or whether there might be a genetic component to your infertility -- without having to get approval from your doctor, consult a genetic counselor or risk the fallout that might result from filing an insurance claim.
Now imagine sitting alone at your home computer and receiving devastating news: test results that will forever change your life -- and your family's -- in ways you never anticipated.
Those are the promises and perils of the nascent, growing and largely unregulated phenomenon of direct-to-consumer (DTC) genetic tests. For the price of a mail order test kit containing swabs to scrape cells inside the cheek, nearly a dozen companies now offer curious consumers the chance, without ever seeing a doctor, to learn whether they carry genes for cancer, blood disorders or other diseases. Some companies are marketing personalized diet or skin care recommendations based on DNA analysis using tests that are not widely accepted in the scientific community.

I was immediately reminded of an issue I worked on when I was an advocate for artists and cultural organizations. In 2001, the United States Immigration and Naturalization Service (now the U.S. Citizenship and Immigration Services) implemented a $1000 premium processing fee for non-immigrant visa applications. This service worked in favor of businesses who could pay the fee to have the applications of new foreign employees processed in 15 days, but it significantly lengthened the time it took to process non-premium application (to as much as 120 days). As a result, the visa applications of international artists who could not pay the fee were delayed enough that some missed their own performances in the
I was a little groggy when I heard this news and I had missed the first half of the story, so I later Googled around for a matching news article with the information I missed. I didn't find an exact match, but I did find a number of other articles about the phenomenon—that is, concierge medicine or “pay-for-care” services. Concierge-style medical practices charge an annual fee of anywhere from $700 to $6000 for the patient conveniences mentioned above, and additional per-visit fees of $50 to $200 depending on the service provided. Many patients who utilize concierge medical services claim that these fee-based conveniences save them aggravation in obtaining care, provide them with better quality health care, and save them money and time in the long-run. Many of these patients also keep their regular health insurance to cover major and emergency medical needs.
I couldn't help but wonder, if I as a patient could pay the extra fees, why should I, on principle, have to pay anything on top of what I'm already shelling out for health insurance and copays, just to get decent service? Furthermore, would it not be selfish of me to opt for premium service knowing that medical care resources are limited and I would in effect be taking away a level of service from patients who can not afford extra costs?
Should a line be drawn between different kinds of services, those for which premium service is stratified by cost and those for which levels of service must be prioritized by something else? I thought to myself, it's one thing to charge extra fees for a service that does not directly infringe on the rights of an individual. I don't have a problem with the idea of stratefying cost according to speed of package delivery, as it is unlikely to affect any critical aspect of my life (like my health), and the use of premium services do not strain the resources of the delivery company. Health care services are sometimes prioritized by urgency of medical need, for example, in the emergency room, or when my physician will give me a same-day appointment because I have been running a high fever for several days. But once someone else can out-prioritize me by paying more, medical urgency goes out the window.
It then occurred to me that it may be more ethical to run a purely pay-for-service practice, as opposed to a practice that offered fee-based services for those who could afford them but still accepted patients who could not. (I'm not sure exactly how the practice on the news operated.) Some doctors who run concierge-style medical practices in fact claim that they are better able to care for their patients because they see fewer patients without sacrificing revenue and save time by not having to submit health insurance claims for patients. Declining rates of insurance reimbursements for providers was also cited as incentive to run concierge practices.
Still, the existence of a few concierge-style medical practices creates the potential for skew in who gets the better medical care and an environment of “you get what you pay for.” I can imagine that as things currently stand only a very small percentage of the population could or would be willing to pay several thousand more dollars a year for medical care. I am reminded of a conversation I had with a Philadelphia-based psychotherapist about the administrative and cost issues of insurance supplementation for mental health services: she told me that many of her colleagues had chosen to move their practices to

This falls under the category of 'no big surprise' : The federal government should guarantee that all Americans have basic health insurance coverage, says a committee set up by Congress to find out what people want when it comes to health care.
"Assuring health care is a shared social responsibility," says the interim report of the Citizens' Health Care Working Group, a 14-member committee that went to 50 communities and heard from 23,000 people.
The committee describes its recommendations as a framework. The recommendations don't say who would pay for universal health coverage or how much it would cost. The concept of government-guaranteed coverage runs counter to the Bush administration's position that consumers should bear more responsibility for their initial medical expenses.
When Camille Walters plays soccer, her normally brown eyes have a spooky red tint – that’s because of the contact lens designed to give this athlete an edge.
But does these lenses give some athletes an unfair advantage? The associations that govern high school and college sports don't think so, but they're keeping an eye on the lenses.

The federation allows the lenses and puts them in the same category as sunglasses or corrective lenses. The NCAA also allows the sports lenses because it considers them similar to sunglasses.
But Diehl said he's worried about the perception of an unfair advantage.
"If one affluent team can get this, it forces everybody else to go out and do that," Diehl said. "Is it really something that makes a difference? In this instance, at this juncture anyway, it doesn't seem to be any better or any worse than allowing what is already under the rule."
