New genomics tool could help predict tumor aggressiveness, treatment outcomes Posted: 16 Apr 2015 04:27 PM PDT A new method for measuring genetic variability within a tumor might one day help doctors identify patients with aggressive cancers that are more likely to resist therapy, according to a study. Researchers used a new scoring method they developed called MATH (mutant-allele tumor heterogeneity) to measure the genetic variability among cancer cells within tumors from 305 patients with head and neck cancer. High MATH scores corresponded to tumors with many differences among the gene mutations present in different cancer cells.

Facebook users' wishful thinking: Cyberbullying, depression won't happen to me Posted: 16 Apr 2015 04:27 PM PDT Facebook users with so-called optimistic bias think they're less likely than other users to experience cyberbullying, depression and other negative social and psychological effects from using the site, a study finds. The study suggests that optimistic bias, or an intrinsic tendency to imagine future events in a favorable light that enhances positive self-regard -- in other words, wishful thinking -- leaves those Facebook users vulnerable to the negative realities of social media.

Ophthalmologists uncover autoimmune process that causes rejection of secondary corneal transplants Posted: 16 Apr 2015 04:27 PM PDT Ophthalmologists have identified an important cause of why secondary corneal transplants are rejected at triple the rate of first-time corneal transplants. The cornea -- the most frequently transplanted solid tissue -- has a first-time transplantation success rate of about 90 percent. But second corneal transplants undergo a rejection rate three times that of first transplants.

Professional golfers live a lonely life in the midst of rivalries on a meager income Posted: 16 Apr 2015 04:27 PM PDT Many professional golfers live a lonely isolated life in the midst of intense rivalries and on a meager income, new research shows.

Poll: Massachusetts police chiefs favor discretion in issuing concealed gun permits Posted: 16 Apr 2015 04:27 PM PDT Who decides who can carry concealed firearms legally? Should local police chiefs have a say? Massachusetts police chiefs think so. A new survey finds that a majority of Massachusetts police chiefs favor continuing to give local police discretion in whether or not to grant concealed carry hand gun permits in their jurisdiction. Massachusetts is one of nine states with a 'may-issue' concealed carry permit law, which gives a police chief discretion in issuing a gun permit.

Repeated marine predator evolution tracks changes in ancient and Anthropocene oceans Posted: 16 Apr 2015 11:55 AM PDT Scientists synthesized decades of scientific discoveries to illuminate the common and unique patterns driving the extraordinary transitions that whales, dolphins, seals and other species underwent as they moved from land to sea.

After prostate cancer, start walking, experts say Posted: 16 Apr 2015 05:43 AM PDT Walking at an easy pace for about three hours every week may be just enough physical activity to help prostate cancer survivors reduce damaging side effects of their treatment, according to a new study. "Non-vigorous walking for three hours per week seems to improve the fatigue, depression and body weight issues that affect many men post-treatment," said the lead author of the study. "If you walk even more briskly, for only 90 minutes a week, you could also see similar benefits in these areas."

Breastfeeding may prevent postpartum smoking relapse Posted: 16 Apr 2015 05:43 AM PDT While a large number of women quit or reduce smoking upon pregnancy recognition, many resume smoking postpartum. Previous research has estimated that approximately 70 percent of women who quit smoking during pregnancy relapse within the first year after childbirth, and of those who relapse, 67 percent resume smoking by three months, and up to 90 percent by six months. A new study indicates the only significant predictor in change in smoking behaviors for women who smoked during pregnancy was in those who breastfed their infant, finding that women who breastfed their infants for at least 90 days smoked less in the months following childbirth than women who breastfed for a shorter period of time or who did not breastfeed at all.

Increasing evidence points to inflammation as source of nervous system manifestations of Lyme disease Posted: 16 Apr 2015 05:43 AM PDT About 15 percent of patients with Lyme disease develop peripheral and central nervous system involvement, often accompanied by debilitating and painful symptoms.
