A new study provides fascinating insight into the underlying pathology associated with the autoimmune disease, systemic lupus erythematosus (SLE). The research, published by Cell Press in the December issue of the journal Immunity, reveals an unexpected role for a key type of immune cell and provides a potential new therapeutic strategy for SLE and, potentially, other autoimmune diseases.

Challenging students take up more of their teachers' time—and the difference between a tougher student and an easier one appears to be genetic, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. The study looked at young twins in the U.K. and asked their teachers how much of a handful they are.

INDIANAPOLIS –While many studies have looked at the treatment of chronic pain from the patient's perspective, there has been little research on those who provide care for chronic pain.

Modesto, CA (Dec. 16, 2010) – With nearly 16 million Americans living today with prediabetes, a condition that is the precursor to type 2 diabetes, and half of all Americans expected to have either prediabetes or type 2 diabetes by the year 2020, nutritional approaches to maintaining healthy blood sugar levels are essential.1,2 The findings of a scientific study examining the health promotion and disease prevention benefits of almond consumption were published in the June, 2010 Journal of the American College of Nutrition.

Through a complex analysis of protein interactions, researchers from IRB Barcelona and the Joint Programme IRB-BSC have discovered new molecular mechanisms that may be involved in the development of Alzheimer's disease. The study, a collaboration between bioinformaticians and cell biologists, was led by IRB Barcelona group leader and ICREA researcher Patrick Aloy and appears today in the Genome Research, a reference journal in the field of genomics.

In a new report that bucks the concerns raised by the Food and Drug Administration, a Boston University School of Public Health (BUSPH) (sph.bu.edu) researcher concludes that electronic cigarettes are much safer than real cigarettes and show promise in the fight against tobacco-related diseases and death.

A new study by German researchers found that a variation in the PNPLA3 (adiponutrin) gene was associated with cirrhosis of the liver and elevated transaminase (liver enzyme) levels in alcoholic Caucasians. The risk of cirrhosis in alcoholics in the genetic high risk group might be as high as 25% to 50%. Full findings are published in the January 2011 issue of Hepatology, a journal of the American Association for the Study of Liver Diseases.

DURHAM, N.C. -- Scientists now know that some cancer cells spread, or metastasize, throughout the body the old-fashioned way -- by using their feet. But researchers at Duke Cancer Institute have discovered a way to short-circuit their travels by preventing the development of these feet, called invadopodia. This discovery is even more important because preventing the development of these "feet" also eliminates the action of proteins present in the feet that burn through intact tissue and let cancer cells enter new cells.

Researchers from Italy determined that radiofrequency ablation (RFA) is a safe and effective therapy for managing hepatocellular carcinoma (HCC) in cirrhotic patients. The high repeatability of RFA is advantageous in controlling recurrences of cancerous tumors in the liver. Results of this 10-year retrospective study are available in the January 2011 issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases (AASLD).

Washington, DC – The Presidential Commission for the Study of Bioethical Issues today released its first report—a wide-ranging review of the emerging field of synthetic biology—issuing 18 recommendations including a call for coordinated federal oversight of scientists working in both large institutions and smaller settings.

If everyone in the UK ate their "five a day," and cut their dietary salt and unhealthy fat intake to recommended levels, 33,000 deaths could be prevented or delayed every year, reveals research published online in the Journal of Epidemiology and Community Health.

Eating five portions of fruit and vegetables a day accounts for almost half of these saved lives, the study shows. Recommended salt and fat intakes would need to be drastically reduced to achieve similar health benefits, say the authors.
