Stories of athletes bravely “playing through the pain” are relatively common and support the widespread belief that they experience pain differently than non-athletes. Yet, the scientific data on pain perception in athletes has been inconsistent, and sometimes contradictory. Investigators from the University of Heidelberg have conducted a meta-analysis of available research and find that in fact, athletes can indeed tolerate a higher level of pain than normally active people…

One-letter switches in the DNA code occur much more frequently in human genomes than anticipated, but are often only found in one or a few individuals. The abundance of rare variations across the human genome is consistent with the population explosion of the past few thousand years, medical geneticists and evolutionary biologists report in the advanced online edition of Science…

People have more and more chances to participate in genetic testing that can indicate their range of risk for developing a disease. Receiving these results does not appreciably drive up – or diminish – test recipients’ demand for potentially costly follow-up health services, according to a new study in the early online issue of Genetics in Medicine…

Checking the heart of the unborn baby usually involves a stethoscope. However, an inexpensive and accurate Bluetooth fetal heart rate monitoring system has now been developed by researchers in India for long-term home care. Details are reported in a forthcoming issue of the International Journal of Computers in Healthcare. Vijay Chourasia of the LNM Institute of Information Technology in Jaipur and Anil Kumar Tiwari of the Indian Institute of Technology Rajasthan, in Jodhpur, explain how fetal phonocardiography is the modern equivalent of the stethoscope in ante-natal baby care…

A change in the formulation of tenofovir gel, an anti-HIV gel developed for vaginal use, may make it safer to use in the rectum, suggests a study published online this week in the Journal of Antimicrobial Chemotherapy. In laboratory tests of rectal tissue, researchers from the Microbicide Trials Network (MTN) found that the reformulated gel was less harmful to the lining of the rectum than the original vaginal formulation, and just as effective in protecting cells against HIV…

Defects in the gene that encodes the XIAP protein result in a serious immune malfunction. Scientists used biochemical analyses to map the protein’s ability to activate vital components of the immune system. Their results have recently been published in Molecular Cell, a journal of international scientific repute…

Researchers at the Indiana University School of Medicine have developed a test that can predict how likely an individual is to develop schizophrenia. The scientists combined data from several different types of studies in order to identify and prioritize a group of genes most associated with the disease. Combined, these genes can generate a score, and determine whether an individual is at lower or higher risk of developing schizophrenia. The study, which was conducted along with a group of national and international collaborators, is published online in the journal Molecular Psychiatry…

The size of a baby’s head is often related to neurological disorders, such as autism – which affects 1 in 88 children. Now, researchers at Duke University Medical Center have identified genes responsible for head size at birth by inserting human genes into zebrafish. The study is published online in the journal Nature. Nicholas Katsanis, Ph.D., Jean and George Brumley Jr. M.D…

8.3 million (14.85%) seniors in the United States face the threat of hunger, say researchers at the University of Illinois. From 2001 to 2010, the incidence of hunger among seniors has risen by 78%, and by 34% since the onset of the recession in 2007. Craig Gundersen, University of Illinois associate professor of agricultural and consumer economics and executive director of the National Soybean Research Laboratory, said: “In 2005, we reported that one in nine seniors faced the threat of hunger…

Researchers at the University of Chicago have found an association between anxiety disorders and the gene that encodes Glyoxylase 1 (GLO1). However, the mechanism underlying this association is unclear. The most prevalent psychiatric diseases in the United States are anxiety disorders, which range from post-traumatic stress disorder to social phobia. Using a mouse model, Margaret Distler and her team set out to determine whether the primary substrate of GlO1, methylglyoxal, might have unproven neurological effects…
