Long known for promoting the health the expectant mothers
and others, folate also helps moderate oxidative stress, which is linked to aging and disease.

Researchers at the MIT-Harvard Division of
Health Sciences and Technology have come up with a new way to encapsulate living cells in cubes and arrange them into 3-D structures, just as a child would construct buildings out of blocks.

'Votes' of Sub-cellular Variables Control Cell Fate

Members of a population of identical cells often "choose"
different fates, even though they exist in identical conditions. The difference may rest with the "hidden variables" within the cells, said researchers from Baylor College of Medicine in a report that appears in the current issue of the journal Cell.

Baby Corals Dance Their Way Home
Tue, 18 May 2010 12:58:00 -0500
Baby corals find their way home in their first days as free-swimming larvae by
listening to the noise of animals on the reef and actively swimming towards it, an international team of researchers working in the Caribbean has discovered. These findings raise new concerns for the future of coral reefs as increasing human noise pollution in the world's oceans is masking reef sounds.

Hammerhead Sharks of All Sizes Evolved from Single Large Ancestor
Tue, 18 May 2010 12:58:00 -0500
The ancestor of all hammerhead sharks probably appeared abruptly in Earth's oceans about 20 million years ago and was as big as some contemporary hammerheads, according to a new study led by the University of Colorado at Boulder. But once the hammerhead evolved, it underwent divergent evolution in different directions, with some species becoming larger, some smaller, and the distinctive hammer-like head of the fish changing in size and shape.

Kudzu is Major Factor in Surface Ozone Pollution
Tue, 18 May 2010 14:02:00 -0500
Kudzu, an invasive vine that is spreading across the southeastern United States and northward, is a major contributor to large-scale increases of the pollutant surface ozone, according to a study published this week in the journal Proceedings of the National Academy of Sciences. Native to parts of Asia, kudzu produces chemicals which, when combined with nitrogen in the air, form ozone, an air pollutant that causes significant health problems for humans.

Prehistoric Fish Extinction Paved the Way for Modern Vertebrates
Mon, 17 May 2010 15:13:00 -0500
A mass extinction of fish 360 million years ago hit the reset button on Earth's life, setting the stage for modern vertebrate biodiversity. The mass extinction scrambled the species pool near the time at which the first vertebrates crawled from water towards land.
Those few species that survived the bottleneck were the evolutionary starting point for all vertebrates--including humans--that exist today, according to results of a study published this week in the journal Proceedings ...
