Sensor gloves detect obstacles for firefighters in smoky rooms

University of Minnesota researchers have taken a step toward providing first responders with a new means of finding their way through dark or smoky buildings.

Lucy Dunne, an assistant professor in the College of Design’s Department of Design, Housing & Apparel, and graduate student Tony Carton, working with funding from the U’s Minnesota Agricultural Experiment Station to augment the sensory awareness of first responders like firefighters, designed gloves that use ultrasonic sensors to detect walls and other objects.

New research shows fungi living beneath the seafloor are widespread

Fungi living beneath the seafloor are widespread in ocean environments around the world, according to a new paper by scientists at the University of Delaware and Woods Hole Oceanographic Institution.

“They’re ubiquitous,” said co-author Jennifer Biddle, assistant professor of marine biosciences at UD’s College of Earth, Ocean, and Environment. “They are everywhere.” (more…)

Tendency to Fear is Strong Political Influence

Fear can play a role in influencing political attitudes on hot-button issues like immigration, according to new research co-authored by Brown political scientist Rose McDermott. The study, published in the American Journal of Political Science, shows that individuals who are genetically predisposed to fear tend to have more negative out-group opinions, which play out politically as support for policies like anti-immigration and segregation.

PROVIDENCE, R.I. [Brown University] — It’s no secret that fear is a mechanism often used in political campaigns to steer public opinion on hot-button issues like immigration and war. But not everyone is equally predisposed to be influenced by such a strategy, according to new research by Rose McDermott, professor of political science, and colleagues published in the American Journal of Political Science.

Student’s Curiosity Produces Ecological Buzz

Students studying what they love is a well-established principle at Brown. For Tyler Coverdale, that meant the outdoors, the environment, and, ultimately, some provocative research on Cape Cod salt marshes through GIS-assisted analysis of historical aerial photography. He loves it.

Tyler Coverdale’s newly published study in Frontiers in Ecology and the Environment on the collapse of salt marsh habitats along Cape Cod tells an intriguing, if unfortunate, tale of how three different human activities spanning 70 years finally added up to a problem that no one anticipated. The story of how he made the discovery — which is generating some buzz in ecology — while a Brown undergraduate is a tale of happier serendipities. (more…)

Learn about the reasons why social media can be efficient and easy tool in education process!

Students breathe social media; it’s like a drug spreading its tentacles over the younger generation. However, parents and teachers have begun to realize the importance of social media for the younger generation. For instance, they use the Internet databases and social media collaboration as homework writing help tools.

In fact, here is a latest Infographic released by Project Information Literacy on how college students rely on online resources for qualitative study. (more…)

PASADENA, Calif. — NASA’s Mars rover Curiosity is driving toward a flat rock with pale veins that may hold clues to a wet history on the Red Planet. If the rock meets rover engineers’ approval when Curiosity rolls up to it in coming days, it will become the first to be drilled for a sample during the Mars Science Laboratory mission.

The size of a car, Curiosity is inside Mars’ Gale Crater investigating whether the planet ever offered an environment favorable for microbial life. Curiosity landed in the crater five months ago to begin its two-year prime mission. (more…)

Helping Patients Navigate New Cancer Drugs

As cancer treatment in pill form transforms how care is delivered, a new Michigan State University study underscores the challenges patients face in administering their own chemotherapy outside the supervised environment of a cancer clinic.

Chemotherapy pills can target specific cancers better than some traditional intravenous drugs, said Sandra Spoelstra, the MSU assistant professor of nursing who led the study. But they also can be difficult for patients to take. (more…)

UMass Amherst Biochemists Trap a Chaperone Machine in Action, Opening Pathway to Possible New Cancer Treatment

AMHERST, Mass. – Molecular chaperones have emerged as exciting new potential drug targets, because scientists want to learn how to stop cancer cells, for example, from using chaperones to enable their uncontrolled growth. Now a team of biochemists at the University of Massachusetts Amherst led by Lila Gierasch have deciphered key steps in the mechanism of the Hsp70 molecular machine by “trapping” this chaperone in action, providing a dynamic snapshot of its mechanism.

She and colleagues describe this work in the current issue of Cell. Gierasch’s research on Hsp70 chaperones is supported by a long-running grant to her lab from NIH’s National Institute for General Medical Sciences. (more…)
