Public Release: 13-Jun-2013
Oysters could rebound more quickly with limited fishing and improved habitat A new study shows that combining improved oyster restoration methods with limits on fishing in the upper Chesapeake could bring the oyster population back to the Bay in a much shorter period of time. The study led by Michael Wilberg of the University of Maryland Center for Environmental Science's Chesapeake Biological Laboratory assessed a range of management and restoration options to see which ones would have the most likelihood of success.

'Self-cleaning' pollution-control technology could do more harm than good, study suggests Research by Indiana University environmental scientists shows that air-pollution-removal technology used in "self-cleaning" paints and building surfaces may actually cause more problems than they solve. The study finds that titanium dioxide coatings, seen as promising for their role in breaking down airborne pollutants on contact, are likely in real-world conditions to convert abundant ammonia to nitrogen oxide, the key precursor of harmful ozone pollution.

Study: Context crucial when it comes to mutations in genetic evolution New research led by evolutionary biologist Jay Storz of the University of Nebraska-Lincoln has found that whether a given mutation is good or bad is often determined by other mutations associated with it. In other words, genetic evolution is context-dependent. Contact: Jay Storz Public Release: 13-Jun-2013
Gene variants may predict who will benefit from breast cancer prevention drugs In women at high risk for breast cancer, a long-term drug treatment can cut disease risk in half. Researchers have now identified two gene variants that may predict which women are most likely to benefit -- and which should avoid this therapy. There is nearly a six-fold difference in disease risk depending on which gene variants a woman carries. The work represents a major step toward truly individualized breast cancer prevention in high-risk women. Contact: Alisa Z Machalek Public Release: 13-Jun-2013
Warm ocean drives most Antarctic ice shelf loss, UC Irvine and others show Ocean waters melting the undersides of Antarctic ice shelves, not icebergs calving into the sea, are responsible for most of the continent's ice loss, a study by UC Irvine and others has found.

Universal paid sick leave reduces spread of flu, according to Pitt simulation Allowing all employees access to paid sick days would reduce influenza infections in the workplace by nearly 6 percent, according to a first-of-its-kind analysis by University of Pittsburgh Graduate School of Public Health modeling experts. The researchers simulated an influenza epidemic in Pittsburgh and surrounding Allegheny County and estimated it to be more effective for small, compared to large, workplaces. The results are reported in the American Journal of Public Health. Contact: Allison Hydzik Public Release: 13-Jun-2013
Putting flesh on the bones of ancient fish Scientists present for the first time miraculously preserved musculature of 380 million year old armored fish discovered in north-west Australia.

Volunteering reduces risk of hypertension in older adults, Carnegie Mellon research shows It turns out that helping others can also help you protect yourself from high blood pressure. New shows that older adults who volunteer for at least 200 hours per year decrease their risk of hypertension, or high blood pressure, by 40 percent. The study suggests that volunteer work may be an effective non-pharmaceutical option to help prevent the condition. Hypertension affects an estimated 65 million Americans and is a major contributor to cardiovascular disease. Contact: Shilo Rea Public Release: 13-Jun-2013
Austerity cuts to Spanish healthcare system are 'putting lives at risk' A series of austerity reforms made by the Spanish government could lead to the effective dismantling of large parts of the country's healthcare system, with potentially detrimental effects on the health of the Spanish people, according to new research from the London School of Hygiene & Tropical Medicine.

Could novel drug target autism and fetal alcohol disorder? A surprising new study reveals a common molecular vulnerability in autism and fetal alcohol disorder. Both have social impairment symptoms and originate during brain development. The study found male offspring of rat mothers given alcohol during pregnancy have social impairment and altered levels of autism-related genes found in humans. But the damage was reversed with a thyroid hormone given to the mothers during pregnancy. Contact: Marla Paul Public Release: 13-Jun-2013
Be gone, bacteria A team of researchers led by the University of Iowa is recommending clinical guidelines that will cut the post-surgical infection rate for staph bacteria (including MRSA) by 71 percent and 59 percent for a broader class of infectious agents known as gram-positive bacteria. The recommendations come after an extensive review of hospital practices in the US and are published in the British Medical Journal. Contact: Richard Lewis Public Release: 13-Jun-2013
Gustatory tug-of-war key to whether salty foods taste good As anyone who's ever mixed up the sugar and salt while baking knows, too much of a good thing can be inedible. What hasn't been clear, though, is how our tongues and brains can tell when the saltiness of our food has crossed the line from yummy to yucky -- or, worse, something dangerous. Now researchers at the Johns Hopkins University School of Medicine and the University of California, Santa Barbara report that in fruit flies, at least, that process is controlled by competing input from two different types of taste-sensing cells: one that attracts flies to salty foods, and one that repels them.
