A year after the BP explosion and oil spill, those trying to find someone to blame are misguided, says psychological scientist E. Scott Geller, Alumni Distinguished professor at Virginia Tech, and author of a new paper published in Current Directions in Psychological Science, a journal of the Association for Psychological Science. Geller has spent much of his 42-year career developing interventions to keep people safe, particularly helping companies develop a culture that promotes occupational safety. (more…)
Scientists have captured and studied the collision of two asteroids for only the second time in the history of astronomy. In the May 20 edition of the Astrophysical Journal Letters (currently online), UCLA’s David Jewitt and colleagues report on observations from NASA’s Hubble Space Telescope of a large asteroid that was hit by a much smaller one.
On Dec. 11, 2010, astronomers noticed that an asteroid known as (596) Scheila had unexpectedly brightened and was sporting short-lived dust plumes. Data from NASA’s Swift satellite and Hubble Space Telescope showed that these changes likely occurred after Scheila was struck by a much smaller asteroid, probably in late November or early December. The shape, evolution and content of the plumes enabled the scientists to reconstruct what occurred. (more…)
The size and shape of the human cerebral cortex, an evolutionary marvel responsible for everything from Shakespeare’s poetry to the atomic bomb, are largely influenced by mutations in a single gene, according to a team of researchers led by the Yale School of Medicine and three other universities.(more…)
ANN ARBOR, Mich.— Companies involved in merger talks manipulate their stock prices during negotiations by releasing more news than usual, according to a University of Michigan study.
“Media coverage has a significant effect on stock trading and returns,” said Kenneth Ahern, assistant professor of finance at U-M’s Ross School of Business. “Even stale news, if widely publicized, can dramatically raise short-term returns and influence prices of large and widely followed stocks in the S&P 500.”
In their study, “Who Writes the News? Corporate Press Releases during Merger Negotiations,” Ahern and Ross School colleague Denis Sosyura examined more than 500 completed stock mergers of large U.S. publicly traded firms from 2000 to 2008. They studied the frequency and content of news releases issued by acquiring firms, and analyzed more than 617,000 articles in 421 newspapers and newswires worldwide. (more…)
*Strong enterprise and Xbox momentum drive revenue growth of 13% and earnings per share of $0.61.*
REDMOND, Wash. — Apr. 28, 2011 — Microsoft Corp. today announced third-quarter revenue of $16.43 billion for the quarter ended Mar. 31, 2011, a 13% increase from the same period of the prior year. Operating income, net income, and diluted earnings per share for the quarter were $5.71 billion, $5.23 billion, and $0.61 per share, which represented increases of 10%, 31%, and 36%, respectively, when compared with the prior year period. Diluted earnings per share included a $0.05 tax benefit primarily related to an agreement with the U.S. Internal Revenue Service to settle a portion of their audit of tax years 2004 to 2006.
“We delivered strong financial results despite a mixed PC environment, which demonstrates the strength and breadth of our businesses,” said Peter Klein, chief financial officer at Microsoft. “Consumers are purchasing Office 2010, Xbox and Kinect at tremendous rates, and businesses of all sizes are purchasing Microsoft platforms and applications.” (more…)
The brain is apparently programmed from birth to develop the ability to determine sunrise and sunset, new research on circadian rhythms at the University of Chicago shows.
The research sheds new light on brain plasticity and may explain some basic human behaviors, according to Brian Prendergast, associate professor in psychology, and co-author of a paper published April 27 in the journal PLoS One. The lead author is August Kampf-Lassin, an advanced graduate student at the University. (more…)
*Increased Agulhas “leakage” significant player in global climate variability*
The Agulhas Current which runs along the east coast of Africa may not be as well known as its counterpart in the Atlantic, the Gulf Stream. But now researchers are taking a closer look at this current and its “leakage” from the Indian Ocean into the Atlantic Ocean–and what that may mean for climate change.
In results of a study published in this week’s issue of the journal Nature, a team of scientists led by University of Miami Rosenstiel School of Marine & Atmospheric Science Oceanographer Lisa Beal, suggests that Agulhas leakage could be a significant player in global climate variability. (more…)
For over 25 years, Dr. John M. Leventhal has been fighting a battle to protect the lives of hundreds of children who come through one of the child abuse programs at Yale.
He has won many struggles along the way, but to win the war, he says, the program needs to be armed with more state and federal support, as well as support from individuals and foundations.
“Finding ways to protect children who can’t defend themselves is part of what wakes me up in the morning and motivates me to continue this tough, but important work,” says Leventhal, professor of pediatrics at Yale School of Medicine and director of the Child Abuse Programs at Yale-New Haven Children’s Hospital.
