...Canadian researchers' findings were somewhat unexpected, given that previous studies on the issue have typically focused on aerobic exercise, which experts believe enhances cognitive function by promoting blood flow to the brain. Liu-Ambrose says her team speculated that anaerobic weight training would have a similar effect for other reasons. First, a resistance-training regimen requires a considerable amount of learning, especially for elderly people who may not be accustomed to the equipment. To learn how to use dumbbells, a leg press or a latissimus pull-down machine correctly, for example, the volunteers were required to focus on the task...
...AIDS field. As a physician at the University of California, Los Angeles, in the early 1980s, he began keeping a diary of patients who were rushed to the emergency room with a mysterious amalgam of symptoms such as pneumonia, cancer and, most important, a devastating drop in immune function. After a few months, he noticed a pattern: most of the patients were gay men. Intrigued, he became nearly obsessive about chronicling the growing wave of cases. Within two years, Ho and the rest of the world would know that they were seeing the first cases of AIDS...
...docks; HIV berths in one, and ibalizumab in another, leaving the cell free to fight other pathogens. "If CD4's binding site to HIV is with its nose, then this antibody is binding to the back of CD4's neck," Ho says. That means the cell's ability to function as a pathogen troller is not impaired by being coupled to ibalizumab. "There is a solid scientific rationale for what they are attempting to do," says Harvard's Walker...
...accurate. With the flurry of consumer complaints out there, most of the companies seem to be responding. HP has offered instructions on how to adjust its webcam's sensitivity to backlighting. Nikon says it's working to improve the accuracy of the blink-warning function on its Coolpix cameras. (Sony wouldn't comment on the performance of its Cyber-shot cameras and said only that it's "not possible to track the face accurately all the time.") Perhaps in a few years' time, the only faces cameras won't be able to pick up will be those of the blue...
...draw on near-death experiences to reach conclusions about life after actual death. But is that comparing apples and oranges? Scientifically speaking, interviewing people that have permanently died is challenging. Obviously, given that impossibility, we have to do the next best thing. If these people have no brain function, like you have in a cardiac arrest, I think that is the best, closest model we're going to have to study whether or not conscious experience can occur apart from the physical brain. The research shows the overwhelming answer is absolutely...
