A new species of plant-eating dinosaur with tiny, 1-inch-long jaws has come to light in South African rocks dating to the early dinosaur era, some 200 million years ago.
This “punk-sized” herbivore is one of a menagerie of bizarre, tiny, fanged plant-eaters called heterodontosaurs, or “different toothed reptiles,” which were among the first dinosaurs to spread across the planet. (more…)
A current focus in global health research is to make medical tests that are not just cheap, but virtually free. One such strategy is to start with paper – one of humanity’s oldest technologies – and build a device like a home-based pregnancy test that might work for malaria, diabetes or other diseases.
A University of Washington bioengineer recently developed a way to make regular paper stick to medically interesting molecules. The work produced a chemical trick to make paper-based diagnostics using plain paper, the kind found at office supply stores around the world. (more…)
Through a new Multidisciplinary University Research Initiative (MURI) awarded by the Air Force Office of Scientific Research, Brown will lead an effort to study new optical materials and their interactions with light at the quantum scale. The initiative, which includes six other top universities, will receive $4.5 million over three years, with a possible two-year extension.
Harnessing the power of light at the quantum scale could clear the way for superfast optical microprocessors, high-capacity optical memory, securely encrypted communication, and untold other technologies. But before any of these potential applications sees the light of day, substantial obstacles must be overcome — not the least of which is the fact that the wavelength of light is larger than quantum-scale objects, limiting the range of possible light-matter interactions.

GAINESVILLE, Fla. — By analyzing the genes of bacteria, University of Florida researchers have moved a step closer to pinpointing how two brain disorders common in small-breed dogs occur.
The researchers found that the bacteria, known as Mycoplasma canis, invade dog’s cells and suppress their immune system responses. (more…)
Created on recommendation of the 2006 Report of the Brown University Steering Committee on Slavery and Justice, the new Center for the Study of Slavery and Justice will expand upon the work of that committee, creating a space for student and faculty research and public discussion of the history and legacies of these issues. Here, inaugural director B. Anthony Bogues shares his vision for the Center.
PROVIDENCE, R.I. [Brown University] — In 2003, a University steering committee undertook a three-year project on slavery and justice. One of the committee’s recommendations was the creation of a center that would continue to expand upon that work. Earlier this year, Anthony Bogues was named director of the new center. He is hiring staff and finding the center a permanent home on campus, which he expects to have within the next two years. For now, the Center will be located in Alumnae Hall.
Part of the center’s mission will be to act as a public forum for the discussion of the history of slavery and its legacy. On Wednesday, Oct. 3, the center and the Office of the Dean of the College will sponsor the 2012 First Readings Lecture, which will take place at 5 p.m. in the Salomon Center for Teaching. Author Charles Rappleye will discuss his book Sons of Providence: The Brown Brothers, the Slave Trade and the American Revolution. (more…)
Trees Face Rising Drought Stress and Mortality as Climate Warms
LOS ALAMOS, N.M. — Combine the tree-ring growth record with historical information, climate records, and computer-model projections of future climate trends, and you get a grim picture for the future of trees in the southwestern United States. That’s the word from a team of scientists from Los Alamos National Laboratory, the U.S. Geological Survey, University of Arizona, and other partner organizations.
The research, published in Nature Climate Change this week, concluded that if the Southwest is warmer and drier in the near future, widespread tree mortality likely will cause substantial changes in forest and species distributions. (more…)
Students use tornado-chasing technology to research rain’s impact on stream
COLUMBIA, Mo. – With advances in meteorology technology, predicting storms is becoming easier than in the past. While most meteorology students learn about these new technologies in the classroom and don’t get a chance to use sophisticated equipment until they are on the job, a group of University of Missouri students were able to test a mobile weather tracking device, Doppler on Wheels (DOW), made famous by shows such as Discovery Channel’s Storm Chasers.
The DOW visiting MU is one of a fleet of radar trucks maintained by the Center for Severe Storm Research. Each radar truck is mounted with a Doppler weather radar dish. The fleet also consists of a support vehicle and three trucks that deploy instruments to track weather patterns in tornadoes and hurricanes. One of the radar trucks was brought to MU so that students could learn about the technology first-hand. (more…)
As the U.S. presidential election approaches, many voters become voracious consumers of online political news. A tool by a University of Washington researcher tracks whether all those articles really provide a balanced view of the debate – and, if not, suggests some sites that offer opinions from the other side of the political spectrum.
Balancer, a free plug-in for Google’s Chrome browser, was developed this summer by Sean Munson, a new UW assistant professor of Human Centered Design and Engineering. The tool analyzes a person’s online reading habits for a month and calculates the political bias in that behavior. It then suggests sites that represent a different point of view and continues to monitor reading behavior and offer feedback. (more…)
