Polarized microscopy technique shows new details of how proteins are arranged
By harnessing the unique properties of polarized light, Rockefeller scientists have developed a new technique that can help deduce the orientation of specific proteins within a cell.

Scientists develop compound that effectively halts progression of multiple sclerosis
Scientists from the Florida campus of the Scripps Research Institute have developed the first of a new class of highly selective compounds that effectively suppresses the severity of multiple sclerosis in animal models.

Ancestors of land plants revealed
It was previously thought that land plants evolved from stonewort-like algae.

Fatal overdose rate reduced by over one third in area near Canada's supervised injecting facility
North America's first supervised injecting facility (SIF) in Vancouver, Canada has helped to reduce the number of fatal overdoses in the community by 35 percent.

Arctic coasts on the retreat
The coastline in Arctic regions reacts to climate change with increased erosion and retreats by half a meter per year on average.

Successful strategy developed to regenerate blood vessels
Researchers at the University of Western Ontario have discovered a way to stimulate the formation of highly functional new blood vessels.

Researchers inject nanofiber spheres carrying cells into wounds to grow tissue
For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue.

Missing the gorilla
University of Utah psychologists have learned why many people experience

L-lysine may help schizophrenia sufferers cope
Schizophrenia is a serious mental disorder that currently affects about one in every 200 people.

La Jolla Institute identifies new therapeutic target for asthma, COPD and other lung disorders
Michael Croft, Ph.D., a researcher at the La Jolla Institute for Allergy & Immunology, has discovered a molecule's previously unknown role as a major trigger for airway remodeling, which impairs lung function, making the molecule a promising therapeutic target for chronic asthma, chronic obstructive pulmonary disease (COPD) and several other lung conditions.

Sugarcane cools climate
Brazilians are world leaders in using biofuels. About a quarter of their automobile fuel consumption comes from sugarcane, which significantly reduces carbon dioxide emissions.

Researchers get a first look at the mechanics of membrane proteins
In two new studies, researchers provide the first detailed view of the elaborate chemical and mechanical interactions that allow the ribosome -- the cell's protein-building machinery -- to insert a growing protein into the cellular membrane.
