No matter what novel objects we come to behold, our brains effortlessly take us from an initial "What's that?" to "Oh, that old thing" after a few casual encounters. In research that helps shed light on the malleability of this recognition process, Brown University neuroscientists have teased apart the potentially different roles that two distinct cell types may play. In a study published in the journal Neuron, the researchers document that this kind of learning is based in the inferior...

Researchers at Brown University and Hasbro Children´s Hospital have traced the molecular interactions that allow the protein survivin to escape the nucleus of a breast cancer cell and prolong the cell´s life. The study may help in the development of better therapies and prognostics. If the fight against breast cancer were a criminal investigation, then the proteins survivin, HDAC6, CBP, and CRM1 would be among the shadier figures. In that vein, a study to be published in the March...

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 breast cells. Results are published in Nanotechnology. One in eight women in the United States will develop breast cancer. Of those, many will...

An article released by Social Forces indicates that voter identification requirements have a substantially negative impact on the voting of all groups except for Asians. Particularly strong negative effects are seen for Blacks and Hispanics: a decrease in voting by 18 percent and 22 percent respectively. Even Whites show dampened turnout associated with voter ID policies. Yet for Asians, strikingly, voter ID has the opposite effect, boosting turnout by nearly 30 percent. This is an intriguing...

Chemists at Brown University have created a triple-headed metallic nanoparticle that reportedly performs better and lasts longer than any other nanoparticle catalyst studied in fuel-cell reactions. The key is the addition of gold: It yields a more uniform crystal structure while removing carbon monoxide from the reaction. Results published in the Journal of the American Chemical Society. Advances in fuel-cell technology have been stymied by the inadequacy of metals studied as catalysts....

The evolution of plants and animals generally has been thought to occur through the passing of genes from parent to offspring and genetic modifications that happen along the way. But evolutionary biologists from Brown University and the University of Sheffield have documented another avenue, through the passing of genes from plant to plant between species with only a distant ancestral kinship. How this happened is unclear. But the researchers show that not only did a grouping of grasses...

Weight Loss Can be Contagious

[ Watch the Video ] Is weight loss “contagious”? According to a new study published online in the journal Obesity, teammates in a team-based weight loss competition significantly influenced each other´s weight loss, suggesting that shedding pounds can have a ripple effect. Researchers from The Miriam Hospital´s Weight Control and Diabetes Research Center and The Warren Alpert Medical School of Brown University found that team members not only achieved similar...

Moderate Air Pollution Linked To Stroke, Cognitive Decline
2012-02-14 06:06:21

Chronic exposure to air pollution, even at levels typically considered safe by federal regulations, increases the risk of stroke by 34 percent and may accelerate cognitive decline in older adults, according to two separate studies published this week in the Archives of Internal Medicine. In one study, researchers studied more than 1,700 stroke patients in the Boston area over a 10-year period, and found exposure to ambient fine particulate matter (PM), generally from vehicle traffic, was...

Strategy for maximizing uncertain rewards shows in MRI, math models Life shrouds most choices in mystery. Some people inch toward a comfortable enough spot and stick close to that rewarding status quo. Out to dinner, they order the usual. Others consider their options systematically or randomly. But many choose to grapple with the uncertainty head on. "Explorers" order the special because they aren't sure they'll like it. It's a strategy of maximizing rewards by discovering whether as yet...
