<p>For Most Outfielders, Luck Has Nothing to Do with Catching Flies</p>

<p>New research from Brown University supports a long-standing theory about how outfielders catch fly balls. The eye continuously tracks the ball as its visual velocity increases or decreases, and the outfielder runs backward or forward to compensate. Details are online at the <em>Journal of Vision.</em></p>

<p>Tavis Smiley to Deliver Martin Luther King Jr. Lecture</p>

<p>Noted broadcaster and author Tavis Smiley will deliver the Martin Luther King Jr. Lecture at Brown University on Thursday, Feb. 4, 2010, at 5 p.m. in the Salomon Center for Teaching, De Ciccio Family Auditorium. His talk is free and open to the public.</p>

<p>Researchers Find Cells Move in Mysterious Ways</p>

<p>Scientists at Brown University and the California Institute of Technology have for the first time tracked how cells move in three dimensions by measuring the force exerted by them on their surroundings. The scientists' experiments revealed that cells move in a push-pull fashion, such as probing at depth, redistributing weight at various points and coiling and elongating. Results appear online in the <em>Proceedings of the National Academy of Sciences</em>.</p>

<p>RI Poll Finds Moderate Support for Health Care Reform, War in Afghanistan</p>

<p>A new Brown University poll finds moderate support among Rhode Island voters on the issues of health care reform and the war in Afghanistan. A large majority of respondents describes the nation and state's economy as poor. The survey, conducted Dec. 4-6, 2009, is based on a sample of 442 registered voters in Rhode Island.</p>

<p>Sucker-Footed Bats Don’t Use Suction After All</p>

<p>In first-time experiments in the wild, a researcher at Brown University has discovered that a species of bat in Madagascar, <em>Myzopoda aurita,</em> uses wet adhesion to attach itself to surfaces. The finding explains why the bat — unlike almost all others — roosts head-up. It also helps to explain how it differs from a similar head-up roosting species. Results appear in the <em>Biological Journal of the Linnean Society.</em></p>

<p>Controlling Key Enzyme in Brain Offers Clue For Future Obesity Treatment</p>

<p>Researchers from Brown University, Rhode Island Hospital and elsewhere have determined that inhibiting the Sirt1 enzyme in the brain appears to help control food intake. Activating Sirt1 elsewhere in the body — by fasting or with red wine — is thought by some to help people live longer. Details of the new Sirt1 brain finding will be published online Dec. 15, 2009, in the journal PLoS ONE.</p>

<p>Newly Discovered Mechanism Allows Cells To Change State</p>

<p>By looking at yeast cells, Jeffrey Laney, assistant professor of biology, has figured out one way in which cells can transform themselves: a cellular “machine” removes a regulatory “lid.” Details are published online in <em>Nature Cell Biology.</em></p>

<p>Achebe Colloquium to Focus on 2010 Nigerian Elections</p>

<p>An international gathering of scholars, government officials, and civil society groups from Nigeria, Europe, and the United States will explore the problems and prospects of the upcoming Nigerian elections during the 2009 Achebe Colloquium Friday, Dec. 11, 2009.</p>

<p>Oceanic Crust Formation Is Dynamic After All</p>

<p>Earth scientists at Brown University have found strong evidence that the geological processes that lead to the formation of oceanic crust are not as uniformly passive as believed. The team found centers of dynamic upwelling in the shallow mantle beneath spreading centers on the seafloor. Findings are published in this week’s <em>Nature</em>.</p>

<p>Possible Link Studied Between Childhood Abuse and Early Cellular Aging</p>

<p>Researchers from Brown University and Butler Hospital have determined that children who suffer physical or emotional abuse may be faced with accelerated cellular aging as adults. The findings are published online in the journal <em>Biological Psychiatry.</em> A print version of the articled is also expected.</p>
