Just how bad Is the new bird flu?
Water birds, to an influenza researcher, are more than majestic swans and charming mallards. They are instead stealthy vectors of novel influenza viruses, some of nature's bioterrorist agents, chauffeuring dangerous microbes from place to place without showing symptoms of infection themselves. Wild waterfowl are reservoirs for every imaginable combination of influenza viruses, though the vast majority of those viral cocktails don't seem to infect humans.

Fossils show ancient ancestor had unique anatomy for tree-climbing, walking
The fossilized remains of a human- like species that lived 2 million years ago suggest the ancestor ate forest food and used its unique anatomy to climb trees and walk upright on the ground to fetch it.

Invisibility cloak is a visible burden on physicists
Invisibility cloaks seem to be an enduring staple of science fiction and fantasy. When I was growing up, this was most evident in "Star Trek." For the last decade or so, it's been Harry Potter. The allure is not surprising — I expect that everyone has had a fantasy, at some time or another, about being invisible. Whether the motivation is to get a free peep show or escape out of, or into, dangerous situations, the freedom offered by disappearing into the background is compelling. The real question, of course, is: Will it ever be possible?

A new reason why red meat, and some energy drinks, may be bad for our heart
Our guts are awash in bacteria, and now a new study fingers them as culprits in heart disease. A complicated dance between the microbes and a component of red meat could help explain how the food might cause atherosclerosis. The work also has implications for certain energy drinks and energy supplements, which contain the same nutrient that these bacteria like chasing after.

Problem Child? Early Puberty May Not Be the Cause
Puberty has always been a time of stress and emotional turmoil for adolescents and for their parents. And scientists have long recognized that kids who start puberty ahead of their peers are particularly likely to have trouble getting along with other children and with adults. New research suggests that those difficulties can be traced back to even earlier ages, indicating that early puberty may not be the root cause.

Flushed Drugs May Threaten River Slime
Most streams that flow near cities and towns are laced with drugs that escape from sewage treatment plants or pharmaceutical factories. Although often occurring at concentrations of a few parts per trillion, these compounds can nevertheless hurt aquatic life, turning male fish into female fish with hormones or giving them the munchies with antianxiety medication. Now comes the first study that shows an effect of drugs on the base of the food web-the nutritious microbial slime that covers the streambed. Experts caution, however, that the work is
