A new Brown study finds that bats take advantage of their flexibility by folding in wings on the upstroke to save inertial energy.
The research suggests that engineers looking at flapping flight should account for wing mass and consider a folding design.

In a study in The New England Journal of Medicine, authors including biostatisticians from Brown report that coronary computed tomographic angiography (CCTA) is a safe way to screen patients coming to the ER with chest pains who are not at high risk for acute coronary syndrome.
Patients who got CCTA and tested negative were more likely to be discharged home and spend less time at the hospital.

Brown University biologists have found a new molecule in fruit flies that is key to the information exchange needed to build wings properly.
They have also uncovered evidence that an analogous protein may exist in people and may be associated with problems such as cleft lip, or premature ovarian failure

Researchers at Brown University have created an implant that appears to deter breast cancer cell regrowth.
Made from a common federally approved polymer, the implant is the first to be modified at the nanoscale in a way that causes a reduction in the blood-vessel architecture that breast cancer tumors depend upon, while also attracting healthy endothelial cells for breast tissue.
Results are published in Nanotechnology.

Many environmental and public health officials are concerned about the potential health effects of phthalates, which are common chemicals used to make plastics softer and more pliable. In the first study to examine what effect in utero doses of phthalates have on the reproductive system of mice, Brown University toxicologists found that extremely high doses were associated with significant changes, such as a shortened reproductive lifespan and abnormal cell growth in mammary glands.

According to a new analysis of hundreds of recorded office visits, doctors and nurse practitioners typically issued orders and asked closed or leading questions when talking to their HIV-positive patients about adherence to antiretroviral therapy. Attempts at problem-solving with patients who had lapsed occurred in less than a quarter of visits.

The Choices Program, an initiative developed at Brown’s Watson Insitute for International Studies, has received the Franklin R. Buchanan Award. Established in 1995 by the Association for Asian Studies Committee on Educational Issues and Policy and the Committee on Teaching about Asia, the Buchanan Award is awarded annually to recognize an outstanding curriculum publication on Asia designed for any educational level, elementary through university.
The curriculum that won the award, The United States in Afghanistan, was published in September 2011 and designed for secondary-school social studies classrooms. The curriculum provides students with primary source documents, readings, and new media sources and asks them to engage in role playing to help them consider the future of U.S. policy in Afghanistan. The curriculum development was funded by a grant from the Carnegie Corporation of New York.
