RNA molecule behind behavior changes cued by environment

Quick changes in behavior – in worms, at least – can be triggered by a unique form of the molecule RNA acting within the nucleus of a cell, UC San Francisco researchers have discovered.

The developmental on-switch

German researchers have demonstrated for the first time why the molecular cocktail responsible for generating stem cells works. Sox2 and Oct4 are proteins whose effect on cells resembles that of an eraser: They remove all ...

Rethinking the value of sewage sludge 

Researchers from the Plant Nutrition Group at ETH Zurich have been evaluating methods to develop an efficient and environmental friendly phosphate fertilizer from sewage sludge ashes. A new thermo-chemical process that extracts ...

Preventing the spread of repression

Scientists at the Friedrich Miescher Institute for Biomedical Research have identified a novel and unexpected regulatory activity of RNA at the edge of inactive chromosomal regions. In their publication in Nature Structural ...

Scientists solve a 14,000-year-old ocean mystery

At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, ...

Bioluminescence reveals deep-water motion in the Mediterranean

In 2009 and 2010, the underwater neutrino telescope ANTARES detected an unusual phenomenon: the bioluminescence of deep-sea organisms suddenly increased, revealing an unexpected connection between biological activity-bioluminescence-and ...
