Rapidly growing trees like poplars and willows are candidate “biofuel crops” from which it is expected that cellulosic ethanol and higher energy content fuels can be efficiently extracted. Domesticating these crops requires a deep understanding of tree… Continue reading

People living in Arctic areas can be more sensitive to pollutants due to their genetics. This is unfortunate since the northernmost areas of Europe are receiving more harmful chemicals. Scientists believe climate change may be a culprit as air and wate… Continue reading

New work expands the understanding of how Th17 cells develop, and how their growth influences the development of immune responses. By figuring out how these cells are “wired,” the researchers make a surprising connection between autoimmunity and salt c… Continue reading

A team of political scientists and neuroscientists has shown that liberals and conservatives use different parts of the brain when they make risky decisions, and these regions can be used to predict which political party a person prefers. The new study… Continue reading

The general response to gravity in plants is well known: roots respond positively, growing down, into the soil, and stems respond negatively, growing upward, to reach the sunlight. But how do plants sense gravity and direct or signal their cells to gro… Continue reading

Genetics researchers have identified 25 copy number variations (CNVs) that occur in some patients with autism. While individually rare, these CNVs are “high impact,” strongly increasing a person’s autism risk. Continue reading
