Velvet spiders include some of the most beautiful arachnids in Europe and some of the world's most cooperative species. Social species can be very abundant in parts of tropical Africa and Asia with conspicuous colonies dotting the landscape. Social colonies may consist of hundreds of closely-related individuals that participate in dramatic mass attacks on prey (Figure 1) and care for their young. The ecology of these social species is fascinating and has been the subject of several landmark scientific papers.

Scientists are reporting development of a healthy "designer fat" that, when added to infant formula, provides a key nutrient that premature babies need in high quantities, but isn't available in large enough amounts in their mothers' milk. The new nutrient, based on hazelnut oil, also could boost nutrition for babies who are bottle-fed for other reasons. The report appears in ACS' Journal of Agricultural and Food Chemistry.

Millions of teenagers suffer from acne, and they deal with the embarrassing skin blemishes by taking popular prescription medications such as Accutane or Roaccutane. Now, however, research from Tel Aviv University shows that these pills can also cause eye infections such as conjunctivitis (pink eye) or sties.

DURHAM, N.C. – Women receiving care for breast cancer have significantly impaired cardio-pulmonary function that can persist for years after they have completed treatment, according to a study led by scientists at Duke University Medical Center.

The findings, reported online in the Journal of Clinical Oncology, also provide initial evidence that poor cardio-pulmonary function may be a strong predictor of survival among women with advanced breast cancer.

(Boston) - New studies led by researchers from Boston University School of Medicine (BUSM) shows specific genetic traits may predispose people to their preferences for social, spiritual and political behaviors. The findings, which will be published in the X issue of Genetic Syndromes and Gene Therapy, also suggests that a voter's genetic information may predict presidential outcomes more than the actual issues at hand or the presidential candidates themselves.

The hordes of bark beetles that have bored their way through more than 6 billion trees in the western U.S. and British Columbia since the 1990s do more than damage and kill stately pine, spruce and other trees. A new study finds that these pests can make trees release up to 20 times more of the organic substances that foster haze and air pollution in forested areas. It appears in ACS' journal Environmental Science & Technology.

Army scientists and industry collaborators have successfully protected laboratory animals from lethal hantavirus disease using a novel approach that combines DNA vaccines and duck eggs. The work appears in a recent edition of the online scientific journal PLoS ONE, published by the Public Library of Science.

PITTSBURGH, May 23 – In one of the most comprehensive analyses to date of the cost of robotic-assisted, laparoscopic surgery for prostate cancer, researchers at UPMC found that this now-dominant surgical approach is significantly more costly than standard open surgery, despite little scientific evidence of long-term improved patient outcomes. The results of the study are available online and will appear in the July issue of the journal Urology.

PROVIDENCE, R.I. – Blame it on your genes? Researchers from The Miriam Hospital's Weight Control and Diabetes Research Center say individuals with variations in certain "obesity genes" tend to eat more meals and snacks, consume more calories per day and often choose the same types of high fat, sugary foods.

London, UK (May 23, 2012) – The British Association for Psychopharmacology (BAP) has released fresh guidelines on the best methods to treat substance abuse and addiction in the Journal of Psychopharmacology, published by SAGE. A panel of experts has carefully researched the new, comprehensive guidelines, offering practitioners a detailed review of the evidence to help them optimise their clinical decisions.

The diagnosis of male fertility is usually performed through the observation of the sperm in the microscope. However, a normal quality semen does not guarantee an adequate fertility. In fact, there is a considerable proportion of cases of unexplained infertility and data suggest that abnormal sperm function may have a genetic or molecular origin.

Malformed desmin proteins aggregate with intact proteins of the same kind, thereby triggering skeletal and cardiac muscle diseases, the desminopathies. This was discovered by researchers from the RUB Heart and Diabetes Center NRW in Bad Oeynhausen led by PD Dr. Hendrik Milting in an interdisciplinary research project with colleagues from the universities in Karlsruhe, Würzburg and Bielefeld. They report in the Journal of Biological Chemistry.

One defective gene is enough

A team from the Institute of Photonic Sciences (ICFO) has developed a technique to measure internal cell temperatures without altering their metabolism. This finding could be useful when distinguishing healthy cells from cancerous ones, as well as learning more about cellular processes.

ATS 2012, SAN FRANCISCO –Weight loss improved both metabolic parameters and sleep-disordered breathing (SDB) in obese children in a new study from researchers in Belgium, confirming links between metabolic dysregulation, SDB and obesity.

ATS 2012, SAN FRANCISCO –The severity of sleep disordered breathing and nocturnal hypoxemia independently predict both glycosylated hemoglobin (HbA1c) levels and type 2 diabetes mellitus (T2DM), according to a new study.
