Termites feed through good vibrations

...termites use their ability to detect vibrations to determine which food source is most suitable. The termites can also detect how the vibrations are made. This ability could be likened to a form of sonar. Dr Evans says different termite species are known to prefer eating particular sizes of wood; certain dryw...

UCLA Study Shows One-Third of Drug Ads in Medical Journals Do Not Contain References Supporting Medical Claims

Researchers also determined the funding sources of research cited in the ads. The study is published in the Feb. 15 issue of the Canadian Medi...

Elusive HIV shape change revealed; Key clue to how virus infects cells

... answer." One of the lab's first steps will be to determine which shape of gp120 ?bound to the CD4 receptor, or unbound ?is recognized by a person's antibodies. gp120's shape change is an important "escape mechanism" for HIV, allowing the virus to bind to and enter a cell before the immune system can "see" it...
