...ext to land plants in terms of diversity. To their surprise they found that over long periods of time, 'gaps', or differences in their life histories, opened up between the evolving parasitoid wasp species, which are not filled by others. They suggest this may explain the great diversity of wasps seen in natu...Faces age due to fat loss, skin changes - not gravity
PHILADELPHIA To the surprise of many people, the loss of fat and sun exposure play a bigger role than gravity in aging the face, according to a study presented today at the American Society of Plastic Surgeons (ASPS) Plastic Surgery 2004 conference in Philadelphia.

"This suggests how we might change an inhibitor molecule to make it fit the enzyme more perfectly and hence be more effective in blocking that enzyme's action in destroying anticancer drugs," said Dr. Richard V.

In cells lacking Mcm10, the catalytic subunit of the complex--the part that attaches to DNA--was degraded so it could not attach." If the complex cannot attach to DNA, cell division is stop...Global warming: Informal networking is the key to a swift response

"If we take the risk of rapid climate change seriously we must be sure that organisations are able to change and adapt," says Dr Mark Pelling, who led the research.

Scientists have found living archaebacteria only in very extreme conditions, such as surrounding hot hydrothermal vents at the ocean bottom.

"The surprise of this study is that the molecules used to signal development of the organ in the squid are the same that signal for pathogenesis in the case of whooping cough or gonorrhea."

What did surprise Stephens was that the birds that went for the immediate reward were able to "earn" as much or more food in the long run as birds that were forced to wait for the larger reward or to follow a mixed strategy.
