When a batch of bright cosmic objects first appeared in maps in 2008 made with data from the South Pole Telescope, astronomers at the University of Chicago’s Kavli Institute for Cosmological Physics regarded it only as an unavoidable nuisance.
The light sources interfered with efforts to measure more precisely the cosmic microwave background—the afterglow of the big bang. But the astronomers soon realized that they had made a rare find in South Pole Telescope’s large survey of the sky. The spectra of some of the bright objects, which is the rainbow of light they emit, were inconsistent with what astronomers expected from the well-known population of radio galaxies. (more…)
History has long denied the political genius of the Black Panther Party. At worst, its members have been cast as unconscionable criminals. At best, such seminal figures as party founders Huey Newton and Bobby Seale and early supporter Stokely Carmichael have been portrayed as outlaw folk heroes who, propelled by the progressive winds of the late 1960s, dared to take on the establishment.
But a UCLA graduate student in sociology who worked alongside former Panthers a decade ago as a community organizer in Oakland, Calif., didn’t buy the conventional wisdom. (more…)
Better science communication could lead to a more informed American public.
Public acceptance of climate change’s reality may have been influenced by the rate at which words moved from scientific journals into the mainstream, according to anthropologist Michael O’Brien, dean of the College of Arts and Science at the University of Missouri. A recent study of word usage in popular literature by O’Brien and his colleagues documented how the usage of certain words related to climate change has risen and fallen over the past two centuries. Understanding how word usage affects public acceptance of science could lead to better science communication and a more informed public.
“Scientists can learn from this study that the general public shouldn’t be expected to understand technical terms or be convinced by journal papers written in technical jargon,” O’Brien said. “Journalists must explain scientific terms in ways people can understand and thereby ease the movement of those terms into general speech. That can be a slow process. Several words related to climate change diffused into the popular vocabulary over a 30-50 year timeline.” (more…)
Charles Wright, hailed as one of the leading American poets of his generation, has been named the winner of Yale’s 2013 Bollingen Prize for American Poetry.
The Bollingen Prize in American Poetry is among the most prestigious prizes given to American writers.

Taking into consideration its size, an ancient relative of piranhas weighing about 20 pounds delivered a bite with a force more fierce than prehistoric whale-eating sharks, the four-ton ocean-dwelling Dunkleosteus terrelli and – even – Tyrannosaurus rex.
Besides the force of the bite, Megapiranha paranensis appears to have had teeth capable of shearing through soft tissue the way today’s piranhas do, while also being able to pierce thick shells and crack armoring and bones, according to Stephanie Crofts, a University of Washington doctoral student in biology.

Moustaches from the classic handlebar to the dramatic Dali are soon to be cut short as the month of Mo’vember draws to a close, and clean shaven faces return from their period of charitable exile.
Research by a historian at the University of Exeter into the history of shaving and masculinity in eighteenth century Britain shows the advancement of new technologies in steel and the connection between advertising are inextricably linked to a closer shave.
Shaving chimed in with the Age of Enlightenment, where the advance of knowledge through science was encouraged and notions of gentility, polish, and proper self-presentation were hailed. Numerous middle and upper class men in the 18th century known as dandy’s or fops placed a great deal of emphasis on physical appearance, were clean shaven and considered themselves elegant gentlemen. To sport a beard or any form of facial hair was considered to be barbarous or associated with a rustic country cousin, rather than a fashionable man about town. In fashionable circles the period between the Stuarts and the Victorians was a beardless age. (more…)
ANN ARBOR — The fossilized fangs of saber-toothed cats hold clues to how the extinct mammals shared space and food with other large predators 9 million years ago.
Led by the University of Michigan and the Museo Nacional de Ciencias Naturales in Madrid, a team of paleontologists has analyzed the tooth enamel of two species of saber-toothed cats and a bear dog unearthed in geological pits near Madrid. Bear dogs, also extinct, had dog-like teeth and a bear-like body and gait. (more…)
Lecturer explores the imperatives of environmental ethics
Speaking to University of Delaware faculty and students and community members in Brown Lab on Monday night, Oct. 15, environmental philosopher Kathleen Dean Moore discussed how important it is for humans to realize their ethical responsibility to save the world from a climate crisis.
In a lecture titled “Why It’s Wrong to Wreck the World: Climate Change and the Moral Obligation to the Future,” Moore reflected on the relationship humans have with the environment and argued that once humans realize the impact of their actions, they will naturally feel a moral obligation to care for the planet.
