...estations." The machine blows warm air through a flexible hose, which has a rake-like hand piece on the end. It kills lice and nits by drying them out, not by heating them. It works in one 30-minute treatment. Comparatively, chemical treatments require multiple applications 1 to 2 weeks apart. "This resea......ce." The device blows warm air through a flexible hose, which has a rake-like hand piece on the end. It apparently kills lice and nits by drying them out, not by heating them.

"Since we have now shown Paranthropus was flexible in its eating habits over both short and long intervals, we probably need to look to other biological, cultural or social differences to explain its ultimate fate."

...for swallowing their catch whole.

It may look like mistletoe wrapped around a flexible candy cane. But this molecular model shows how some proteins form loops in DNA when they chemically attach, or bind, at separate sites to the double-helical molecule that carries lifes genetic blueprint.
