Coming out of a recession is a tricky thing. Companies feel like it might be time to start ramping production back up, but demand hasn't fully returned, so they hesitate to hire. The conundrum: demand in the U.S. is overwhelmingly consumer-driven and people need to have jobs to feel like it's once again safe to spend money. It's a classic chicken-or-egg problem.

The question then becomes whether such a program creates more economic benefit than it does economic inefficiency by having the government dictate...

...Preventive Services Task Force's new recommendations advised women to begin routine mammograms at age 50 instead of 40 and to switch from yearly to biennial screenings; it also advised women to eliminate breast self-exams altogether.

That concern was put to rest in December, however, when the Senate cast its first votes on health care reform, approving an amendment to guarantee coverage...
...involve embryonic cells. That deserves to be called a breakthrough. The new pups, whose creation in two separate labs in China was announced in July, were the first to be bred from induced pluripotent stem (iPS) cells. These are adult cells (usually skin cells) that scientists reprogram back to their embryonic state by introducing four genes. The reprogrammed stem cells are then programmed again to develop into mice, a feat that has been accomplished before only using embryonic stem cells. Breeding an entire mouse that is itself capable of reproducing - as the mice did in one of the Chinese labs...
...abundant in rodents and newborns, who need it to keep warm right out of the womb, those brown-fat stores shrink and white fat emerges as people age. But now it seems that adults retain more brown fat than previously thought, in deposits in the front and back of the neck, according to a study by Swedish researchers, published in the New England Journal of Medicine in April. Two other studies published in the same journal found that lean people tend to have more of these deposits than obese folks and that brown-fat cells are more active...
