<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>
