Diatom genome reveals key role in biosphere's carbon cycle

...s diatom species uses fats, or lipids, which it is known to store in huge amounts. "Learning the actual pathways they use to metabolize their fats helps explain the ability of diatoms to withstand long periods with little sunlight--even to overwinter--and then start growing really rapidly once they return...

Don't stand so close to me: A new view on how species coexist

...by laying eggs in them, account for a fifth of all known multi-celled species. Their 200,000 species places them approximately next 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 evolvi...

Penn receives grant for initiative to help understand genes' effects on medications

...ariability in the response to medications has been known for decades to play a critical role in limiting the efficacy and safety of drugs. The Penn project seeks to pave the way for a complete understanding of the genetic basis for these sometimes unpredictable responses to medications, as well as the appr...
