Barone is taking his lead from nature to find potential solutions to these performance requirements. He is investigating the properties of polymers created from poultry feather keratin. The protein, keratin, is a m...

Huddling and a drop in metabolism allow penguins to survive the South Pole cold

...) temperature would be in direct conflict with the requirements for successful egg incubation. Therefore, energy savings accrued from huddling might rely on mechanisms other than a lower body temperature. To better understand this mechanism, the researchers conducted the first recordings of deep body tempera...

If so, it would provide an illustration of the potential for studies of diverse species, even those that at first glance may appear to be of ...

A silent pandemic: Industrial chemicals are impairing the brain development of children worldwide

...ire a high level of proof. At present in the U.S., requirements for toxicity testing of chemicals are minimal. "The human brain is a precious and vulnerable organ. And because optimal brain function depends on the integrity of the organ, even limited damage may have serious consequences," says Philippe Grandje...
