Study of antibody evolution charts course toward HIV vaccine
In an advance for HIV vaccine research, a scientific team has discovered how the immune system makes a powerful antibody that blocks HIV infection of cells by targeting a site on the virus called V1V2.

Plants convert energy at lightning speed
A new way of measuring how much light a plant can tolerate could be useful in growing crops resilient to a changing climate, according to scientists from Queen Mary University of London.

Research reveals first glimpse of brain circuit that helps experience to shape perception
Scientists from CSHL demonstrate for the first time a way to observe how our experiences shape sensory information in awake animals.

A highly sensitive small molecule probe to evaluate potential risk for Parkinson's disease
A team of researchers from National University of Singapore have created the first two-photon, small molecule fluorogenic probe that can serve as a useful tool for the rapid assessment of an individual's potential risk for Parkinson's disease.

Newly discovered catalyst could lead to the low-cost production of clean methanol
An international research team has discovered a potentially clean, low-cost way to convert carbon dioxide into methanol, a key ingredient in the production of plastics, adhesives and solvents, and a promising fuel for transportation.

European flood risk could double by 2050
Losses from extreme floods in Europe could more than double by 2050, because of climate change and socioeconomic development.

Imaging dynamics of small biomolecules inside live cells
Researchers at Columbia University have made a significant step toward visualizing small biomolecules inside living biological systems with minimum disturbance, a longstanding goal in the scientific community.

Optical nano-tweezers take over the control of nano-objects
Researchers at the Institute of Photonic Sciences have invented nano-optical tweezers capable of trapping and moving an individual nano-object in three dimensions using only the force of light.

Global warming felt to deepest reaches of ocean
A new study led by researchers from McGill University suggests that the the 1970s polynya in the Antarctic sea ice pack of the Weddell Sea may have been the last gasp of what was previously a more common feature of the Southern Ocean, and which is now suppressed due to the effects of climate change on ocean salinity.

In first moments of infection, a division and a decision
Using technologies capable of tracing the destiny of a single cell, researchers at the University of California, San Diego School of Medicine describe for the first time the earliest stages of fate determination among white blood cells called T lymphocytes, providing new insights that may help drug developers create more effective, longer-lasting vaccines against microbial pathogens or cancer.

Mandatory arrest in domestic violence call-outs causes early death in victims
A Cambridge-Maryland team follows up on a landmark domestic violence arrest experiment and finds that African-American victims who had partners arrested rather than warned were twice as likely to die young.

Detecting levels of antibiotics in blood paves the way to individualized treatment
A new methodology for rapidly measuring the level of antibiotic drug molecules in human blood serum has been developed, paving the way to applications within drug development and personalized medicine.

Eskitis Institute signs beautiful deal with Japanese skin care company
Natural drug discovery research center, Griffith University's Eskitis Institute, has signed a new three year deal with a Japanese skin care company which is searching for biological properties to form the basis of new cosmetic, skin care and functional food products.

Study pinpoints protective mutations for type 2 diabetes
An international team led by researchers at the Broad Institute and Massachusetts General Hospital has identified mutations in a gene that can reduce the risk of developing type 2 diabetes, even in people who have risk factors such as obesity and old age.

As one food allergy resolves, another may develop
Some children who outgrow one type of food allergy may then develop another type of allergy, more severe and more persistent, to the same food.

Entomologists update definitions to tackle resistance to biotech crops and pesticides
The current jumble of terms about insects and weeds that are resistant to pesticides has fostered confusion among scientists.
