...Higgins Professor of Microbiology and Molecular Genetics David Knipe, who has been developing a vaccine for 15 years, said he discovered it unexpectedly after testing mice with mutant viruses...
...after taking cinnamon for 40 days. In a separate study, however, scientists at the University of California at Santa Barbara and the Sansum Medical Research Institute found that not all cinnamon is created equal. While some varieties had no impact, others lowered blood-glucose levels in studies of obese mice...
...pair of lab-mice studies roared in the world of reproductive biology. In the first, scientists created a mouse born by the fusion of two eggs. In the natural world this is known as parthenogenesis (from the Greek for "virgin birth"), a reproductive strategy used by some insects, invertebrates and the odd fish or reptile but unheard of in mammals. Given the technical difficulty, it's unlikely that you'll see this offered at the local IVF clinic anytime soon...
...hold more immediate promise. Conventional wisdom has long held that when a baby girl is born, her ovaries hold all the eggs she will ever have, and that by age 50 or so, they are essentially gone. But that may not be the case, at least not in mice. Researchers discovered that specialized stem cells in the ovaries make new eggs throughout the mouse's life--and there is a hint the same might be true for humans. In theory, that could someday lead to new treatments for infertility and perhaps a new way to stave off menopause...
...addition to refueling the brain, sleep seems to detoxify it. Animals with a high metabolic rate, like field mice and bats, use a lot of calories and generate a lot of destructive molecules called free radicals. "The brain is particularly susceptible to this because neurons, by and large, don't regenerate," says Jerome Siegel, a neuroscientist at UCLA and the Veterans Affairs Medical Center in Los Angeles. Maybe sleep provides necessary downtime so that the brain can deal with all those free radicals...
