Preparing for a thaw: How Arctic microbes respond to a warming world
The Arctic permafrost keeps an estimated 1,672 billion metric tons of carbon out of the Earth's atmosphere but rising global temperatures lead to concerns about potential carbon cycle impacts when the frozen soils thaw.

University of Toronto engineers solve energy puzzle
University of Toronto materials science and engineering researchers have demonstrated for the first time the key mechanism behind how energy levels align in a critical group of advanced materials.

ICRISAT-led team cracks pigeonpea genome
Once referred to as an

Combined arterial imaging technology reveals both structural and metabolic details
A new device that combines two microimaging technologies can reveal both the detailed anatomy of arterial linings and biological activities that, in coronary arteries, could indicate the risk of heart attacks or the formation of clots in arterial stents.

Scripps research team achieves critical step to opening elusive class of compounds to drug discovery
A group of Scripps Research Institute scientists has successfully achieved a major step toward the goal of synthetically producing Taxol® and other complex taxanes on a quest to harness chemical reactions that could enable research on previously unavailable potential drugs.

Sea life 'must swim faster to survive'
Fish and other sea creatures will have to travel large distances to survive climate change, international marine scientists have warned.

Model of enzyme's structure could spur new therapies
Scientists have determined the structure of an enzyme complex that regulates vital cell functions.

HIV study identifies key cellular defence mechanism
Scientists have moved a step closer to understanding how one of our body's own proteins helps stop the human immunodeficiency virus (HIV-1) in its tracks.

Study identifies factors linked with better medication response for treatment of juvenile arthritis
Among patients with juvenile idiopathic arthritis who initiated treatment with the drug etanercept, one-third achieved an excellent response, and this response was associated with low measures of disability at study entry, younger age at the onset of JIA, and fewer disease-modifying antirheumatic drugs used before initiating etanercept, according to a study appearing in JAMA.

Metabolic protein plays unexpected role in tumor cell formation and growth
The embryonic enzyme pyruvate kinase M2 (PKM2) has a well-established role in metabolism and is highly expressed in human cancers.

'Weak evidence' to support exercise referrals
Research commissioned by the NIHR Health Technology Assessment program and carried out by research teams from the Peninsula College of Medicine and Dentistry and the universities of Exeter and Brunel, has called into question the effectiveness of exercise referral schemes as they are delivered at present.

Process important to brain development studied in detail
Knowledge about the development of the nervous system is of the greatest importance for us to understand the function of the brain and brain disorders.

Researchers discover genes involved in colorectal cancer
A jumping gene has helped to unlock vital clues for researchers investigating the genetics of colorectal cancer.

USC microbiologists identify two molecules that kill lymphoma cells in mice
Researchers at the University of Southern California have identified two molecules that may be more effective cancer killers than are currently available on the market.
