*Habitats overlap at Jaco Scar in depths off Costa Rica*
Decades ago, marine scientists made a startling discovery in the deep sea. They found environments known as hydrothermal vents, where hot water surges from the seafloor and life thrives without sunlight. (more…)
Normative support for equality can make the difference
Countries that more strictly uphold their cultural norms are less likely to promote women as leaders, unless those norms support equal opportunity for both sexes, shows a new paper from the University of Toronto’s Rotman School of Management.
“Cultural tightness can prevent the emergence of women leaders because tighter cultures may make a society’s people more resistant to changing the traditionally-held practice that placed men in leadership roles,” said Professor Soo Min Toh, who is cross-appointed to the Rotman School and the University of Toronto Mississauga, and co-wrote the paper with Professor Geoffrey Leonardelli at the Rotman School and U of T’s Department of Psychology.

*Tree trunks, leaves, and kukui nuts indirectly feed bottom fish in submarine canyons off Moloka’i*
Scientists from UH Mānoa’s School of Ocean and Earth Science and Technology (SOEST) recently discovered that land-based plant material and coastal macroalgae indirectly support the increased abundances of bottom fish in submarine canyons, like those off the north shore of Moloka’i. Less than a few miles from the shore, these underwater canyons connect to deep river valleys that cut across the landscape of north Moloka’i. The high elevation and forested landscapes along Moloka’i’s north shore provide plant material, including decomposing tree trunks, leaves and tons of kukui nuts, which enter the ocean via river valleys and “pile up” on submarine canyon floors.

A team of academic researchers has identified the intracellular mechanisms regulated by vitamin D3 that may help the body clear the brain of amyloid beta, the main component of plaques associated with Alzheimer’s disease.
Published in the March 6 issue of the Journal of Alzheimer’s Disease, the early findings show that vitamin D3 may activate key genes and cellular signaling networks to help stimulate the immune system to clear the amyloid-beta protein. (more…)
AUSTIN, Texas — A team of American and Chinese researchers has revealed the detailed feather pattern and color of Microraptor, a pigeon-sized, four-winged dinosaur that lived about 120 million years ago. A new specimen shows the dinosaur had a glossy iridescent sheen and that its tail was narrow and adorned with a pair of streamer feathers, suggesting the importance of display in the early evolution of feathers, as presented in the March 9 edition of the journal Science.
The research was conducted by scientists at the Beijing Museum of Natural History, Peking University, The University of Texas at Austin, the University of Akron, and the American Museum of Natural History. (more…)
ANN ARBOR, Mich.— When faced with job loss, people who consider themselves poor may limit employment prospects by believing they have a smaller social network than they actually do, says a University of Michigan business professor.
“Social networks help explain people’s outcomes in the labor market by determining how people seek help,” said Ned Smith, assistant professor of strategy at the Michigan Ross School of Business. “Network contacts offer two primary resources for job search—information, which provides job seekers with knowledge about where to find employment, and influence, whereby network contacts affect people’s success in actually securing employment by swaying the hiring process.” (more…)
*As the proliferation of devices and cloud services expands the amount of data becoming available globally, Microsoft’s chief privacy officers have focused on developing policies, processes and technologies to help protect users’ personal information.*
REDMOND, Wash. — A mountain climber turned database whiz. A customer loyalty manager for one of the world’s largest banks. A quality assurance and risk management consultant.
The career arcs that led Richard Purcell, Peter Cullen and Brendon Lynch to Microsoft couldn’t have been more different. Yet, in their own unique way, each path was preparation for serving as the corporate privacy officer of one of the world’s largest software and services companies. (more…)
Thanks to the presence of a natural “zoom lens” in space, University of Chicago scientists working with NASA’s Hubble Space Telescope have obtained a uniquely close-up look at the brightest gravitationally magnified galaxy yet discovered. (more…)
