DNA variations signal lupus risk
Scientists have pinpointed a set of common variations in human DNA that signal a higher risk for lupus in women who carry them.

Scientists identify genes linked to lupus in women
An international consortium of scientists has identified multiple genes that are linked to systemic lupus erythematosus, a devastating autoimmune disease that affects between 1 million and 2 million Americans.

Global corporate giants ask suppliers to volunteer CO2 emissions information
The Carbon Disclosure Project, the world's largest collaboration of institutional investors -- 315 entities managing over US $41 trillion -- announces an alliance with a group of the world's largest corporations to measure the CO2 emissions of several hundred firms in their supply chains.

First evidence of under-ice volcanic eruption in Antarctica
The first evidence of a volcanic eruption from beneath Antarctica's most rapidly changing ice sheet is reported this week in the journal Nature Geosciences.

NEJM editorial on significance and limitations of new lupus gene expression research
This week marks a significant step forward in understanding how lupus works with the publication of four new studies identifying genes involved in this often debilitating chronic disease.

Stem-cell transplantation improves muscles in MD animal model, UT Southwestern researchers report
Using embryonic stem cells from mice, UT Southwestern Medical Center researchers have prompted the growth of healthy -- and more importantly, functioning -- muscle cells in mice afflicted with a human model of Duchenne muscular dystrophy.

Ultrasound operator expertise crucial to decreasing the number of major ovarian cancer operations
Improving the quality of pre-operative ultrasound examination could lead to a significant decrease in the number of unnecessary major surgical operations done on women with suspected ovarian cancer, who in fact have benign ovarian disease, according to an article to be published early online and in the February issue of the Lancet Oncology.

Steps toward stopping autoimmune disease
Alliance for Lupus Research International SLEGEN Consortium publishes results of study in Nature Genetics.

A study by the University of Exeter has highlighted the problems of reintroducing animals to the wild for conservation projects.

New technology sharpens X-ray vision
Researchers at the Paul Scherrer Institute and the EPFL in Switzerland have developed a novel method for producing dark-field X-ray images at wavelengths used in typical medical and industrial imaging equipment.

Lupus in women: New genetic risk factors identified
An international consortium of clinical scientists and genomics experts, including researchers from the Montreal Heart Institute and Université de Montréal, have uncovered multiple new genetic risk factors for systemic lupus erythematosus, commonly known as lupus.

Genes linked with lupus are revealed, giving hope for new treatments
Scientists have identified a number of genes involved in lupus, a devastating autoimmune disease, in new research published today in the journal Nature Genetics.

Study: Brain connections strengthen during waking hours, weaken during sleep
New research from the University of Wisconsin School of Medicine and Public Health supports the idea that sleep plays a critical role in the brain's ability to change in response to its environment.
