Nicotine addiction depends on a healthy insula

Smokers with a damaged insula - a region in the brain linked to emotion and feelings - quit smoking easily and immediately, according to a study in the Jan. 26 issue of the journal Science.

SH2B1 protein plays a key role in controlling body weight, response to insulin and leptin

A single protein in brain cells may act as a linchpin in the body's weight-regulating system, playing a key role in the flurry of signals that govern fat storage, sugar use, energy balance and weight, University of Michigan Medical School researchers report.

Cellular mechanism linked to inflammation and cancer

A team led by biochemists at the University of California, San Diego has found what could be a long-elusive mechanism through which inflammation can promote cancer. The findings may provide a new approach for developing cancer therapies.

UK backpackers drinking their way across Australia

The perception that UK backpackers do a lot of drinking while they are travelling across Australia has been supported by new research. Forty per cent reported drinking five or more times a week when in Australia, compared to only just over 20% when they were at home.

Retinoblastoma gene may play a critical role in the development of the placenta

An important cancer-related gene may play a critical role in the development of the placenta, the organ that controls nutrient and oxygen exchange between a mother and her fetus during pregnancy, and perhaps in miscarriages.

Test to detect drug-resistant HIV strains could help provide earlier treatment

A test to detect drug-resistant HIV strains in people with low levels of drug-resistant viral loads could help physicians provide more effective treatment earlier to HIV-positive people, according to a study published on Sunday in the online edition of the journal Nature Methods, BBC News reports.

Optical and magnetic resonance imaging of cell death and platelet activation using annexin A5-functionalized quantum dots

By combining a quantum dot with a novel carrier of the magnetic resonance imaging (MRI) agent gadolinium, a team of investigators at the University of Maastricht, in The Netherlands, has developed a nanoparticle that can spot apoptosis, or programmed cell death, using both MRI and fluorescence imaging.
