ANN ARBOR, Mich.—It’s a message no one wants to hear: To slow down global warming, we’ll either have to put the brakes on economic growth or transform the way the world’s economies work. (more…)
Stephen Roach is a respected authority on Asia — China in particular — and an often-cited and widely recognized prophet on the global economy.
Until recently chair of Morgan Stanley Asia and long the firm’s chief economist, Roach came to Yale in 2010 as a senior fellow in the newly inaugurated Jackson Institute for Global Affairs, with a joint appointment at the School of Management (SOM). This spring Roach announced he would be retiring from Morgan Stanley after 30 years with the firm to teach full time at Yale.
YaleNews recently met with the economist in his office to discuss his new career as a teacher and to get his prognosis on the future of the world economy. (more…)
UD researchers discover that JAM-A protein keeps blood clots in check
Cut your toe, and platelets — those disc-shaped cells circulating in your blood — rush to the scene, clumping together to plug the leak. (more…)
PASADENA, Calif. – Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. NASA’s Galaxy Evolution Explorer, a space-based observatory, and the Pan-STARRS1 telescope on the summit of Haleakala in Hawaii were among the first to help identify the stellar remains.
Supermassive black holes, weighing millions to billions times more than the sun, lurk in the centers of most galaxies. These hefty monsters lie quietly until an unsuspecting victim, such as a star, wanders close enough to get ripped apart by their powerful gravitational clutches. (more…)
EAST LANSING, Mich. — The use of stun guns by police significantly increases the chances of citizen injury, yet also protects the officers more than other restraint methods, according to the most comprehensive research to date into the safety of stun guns in a law enforcement setting. (more…)
Wind pushes plastics deeper into oceans, driving trash estimates up
Decades of research into how much plastic litters the sea may have only skimmed the surface. A new study reveals that wind drives confetti-sized pieces of plastic debris deeper underwater than previously believed, more than doubling earlier estimates of the pollutant’s presence in oceans.
“In windy conditions the traditional approach to measuring plastic marine debris captures only a small fraction of plastic pieces,” said Tobias Kukulka, assistant professor of physical ocean science and engineering in the University of Delaware’s College of Earth, Ocean, and Environment. “Our study helps to better understand how much plastic there is and where, as well as the complexity of the ocean dynamics at work.” (more…)

Berkeley Lab scientists demonstrate the promise of synchrotron infrared spectroscopy of living cells for medical applications
Knowing how a living cell works means knowing how the chemistry inside the cell changes as the functions of the cell change. Protein phosphorylation, for example, controls everything from cell proliferation to differentiation to metabolism to signaling, and even programmed cell death (apoptosis), in cells from bacteria to humans. It’s a chemical process that has long been intensively studied, not least in hopes of treating or eliminating a wide range of diseases. But until now the close-up view – watching phosphorylation work at the molecular level as individual cells change over time – has been impossible without damaging the cells or interfering with the very processes that are being examined.
“To look into phosphorylation, researchers have labeled specific phosphorylated proteins with antibodies that carry fluorescent dyes,” says Hoi-Ying Holman of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). “That gives you a great image, but you have to know exactly what to label before you can even begin.” (more…)
