Evolution: Crabs go deep to avoid hot water

Researchers from the National Oceanography Centre, Southampton, have drawn together 200 years' worth of oceanographic knowledge to investigate the distribution of a notorious deep-sea giant the king crab. The results, published this week in the Journal of Biogeography , reveal temperature as a ...

Our brains make their own marijuana: We're all pot heads deep inside

U.S. and Brazilian scientists have just proven that one of Bob Dylan's most famous lines"everybody must get stoned" is correct. That's because they've discovered that the brain manufactures proteins that act like marijuana at specific receptors in the brain itself. This discovery, published online...

Nature publishes new evidence about the deep biosphere written by biogeoscientists

Biogeoscientists show evidence of 90 billion tons of microbial organismsexpressed in terms of carbon massliving in the deep biosphere, in a research article published online by Nature , July 20, 2008. This tonnage corresponds to about one-tenth of the amount of carbon stored globally in tropical ...

New study shows shallow water corals evolved from deep sea ancestors

New research shows that the second most diverse group of hard corals first evolved in the deep sea, and not in shallow waters. Stylasterids, or lace corals, diversified in deep waters before launching at least three successful invasions of shallow water tropical habitats in the past 40 million yea...

Climate influence on deep sea populations

In an article published in the January 16 issue of PLoS ONE, Joan B. Company and colleagues at the Institut de Cincies del Mar (CSIC) in Spain describe a mechanism of interaction across ecosystems showing how a climate-driven phenomenon originated in shelf environments controls the biological proc...

Planting carbon deep in the earth -- rather than the greenhouse

STORING carbon dioxide deep below the earths surface could be a safe, long-term solution to one of the planets major contributors to climate change. University of Leeds research shows that porous sandstone, drained of oil by the energy giants, could provide a safe reservoir for carbon dioxide. ...

If you want more babies, find a man with a deep voice

Hamilton, ON. Sept. 24, 2007 Men who have lower-pitched voices have more children than do men with high-pitched voices, researchers have found. And their study suggests that for reproductive-minded women, mate selection favours men with low-pitched voices. The study, published in Biology Lett...

Metagenomics of the deep Mediterranean

Metagenomics is a revolutionary approach to study microbes. Rather than isolating pure cultures, the power of high-throughput sequencing is applied directly to environmental samples to obtain information about the genomes of the prokaryotic cells present in a specific habitat studied.

Feather color is more than skin deep

Carotenoids have important physiological functions, including antioxidant, immunomodulating, and photoprotectant properties. Carotenoid pigments are also used by many bird species as colorants, and are responsible for most of their red, orange and yellow coloration. In particular, carotenoid-red c...

From the deep -- Researchers find new species of sea anemone

Researchers cruising for creatures that live in the deepest parts of the Pacific Ocean found a new species of sea anemone living in the unlikeliest of habitats ?the carcass of a dead whale. A marine biologist would say that discovering a new sea anemone isn't so unusual. But finding one that call...

Scientists discover new life in the Antarctic deep sea

Scientists have found hundreds of new marine creatures in the vast, dark deep-sea surrounding Antarctica. Carnivorous sponges, free-swimming worms, crustaceans, and molluscs living in the Weddell Sea provide new insights into the evolution of ocean life. Reporting this week in the journal Nature...

Nanoparticles can track cells deep within living organisms

To the delight of researchers at Washington University School of Medicine in St. Louis, living cells gobbled up fluorine-laced nanoparticles without needing any coaxing. Then, because of the unusual meal, the cells were easily located with MRI scanning after being injected into mice. Developed i...

Researchers now able to look deep into heart to view triggers of a heart's beat

Scientists have long known that the social insects in the order Hymenoptera--which includes ants, bees, and wasps--have an unusual mechanism for sex determination: Unfertilized eggs develop into males, while fertilized eggs become females. But the development of an unfertilized egg into an adult (c...
