COLUMBUS, Ohio – Chronic inhalation of polluted air appears to activate a protein that triggers the release of white blood cells, setting off events that lead to widespread inflammation, according to new research in an animal model. (more…)
It is well known that the human body has a highly developed immune system to detect and destroy invading pathogens and tumor cells. Now, researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the body has a second line of defense against cancer – healthy cells. A new study shows that normal mammary epithelial cells, as they are developing, secrete interleukin 25, a protein known for its role in the immune system’s response to inflammation, for the express purpose of killing nearby breast cancer cells.
“We found that normal breast cells provide an innate defense mechanism against cancer by producing interleukin 25 (IL25) to actively and specifically kill breast cancer cells,” says breast cancer authority Mina Bissell, of Berkeley Lab’s Life Sciences Division, who led this research. “This suggests that IL25 receptor signaling may provide a new therapeutic target for the treatment of breast cancer.” (more…)
*comScore Releases First Public Data on Apple iPad Users from MobiLens Service*
RESTON, VA, April 19, 2011 – comScore, Inc., a leader in measuring the digital world, today released the results of a U.S. study of 
Apple iPad owners, based on data from the comScore MobiLens service. The report includes comScore’s first publicly available data showing demographics and other characteristics of users of connected media devices, such as the iPad and iPod Touch. Initial research indicates that Apple’s iOS platform, which resides on iPhones, iPads and iPod Touches, has a combined platform reach of 37.9 million among all mobile phones, tablets and other such connected media devices, outreaching the Android platform by 59 percent.
“comScore is excited to announce the availability of connected device data as part of the comScore MobiLens service,” said Mark Donovan, comScore senior vice president of mobile. “This new data set enables us to not only understand the comprehensive ecosystem of mobile and connected media device users, but it also allows us insight into their detailed demographic and behavioral attributes.” (more…)
Up equals good, happy, optimistic; down the opposite. Right is honest and trustworthy. Left, not so much. That’s what language and culture tell us. “We use mental metaphors to structure our thinking about abstract things,” says psychologist Daniel Casasanto, “One of those metaphors is space.” (more…)
It’s official. Yale is making the switch from its current email system to Google Apps for Education — a move that is expected to cut costs and free up resources, while expanding the features available to the Yale community. (more…)
IBM scientists, J. Georg Bednorz and K. Alex Muller, discovered the first successful high-temperature superconductor using a breakthrough ceramic material
ZURICH – 18 Apr 2011: Twenty-five years ago IBM scientists, J. Georg Bednorz and K. Alex Muller altered the landscape of physics when they observed superconductivity in an oxide material at a temperature 50 percent higher(1), (-238 deg C, -397 deg F) than what was previously known. This discovery opened an entirely new chapter in the field of physics and earned them the Nobel Prize for Physics in 1987. (more…)
By studying fossilized mollusks from some 3.5 million years ago, UCLA geoscientists and colleagues have been able to construct an ancient climate record that holds clues about the long-term effects of Earth’s current levels of atmospheric carbon dioxide, a key contributor to global climate change.
Two novel geochemical techniques used to determine the temperature at which the mollusk shells were formed suggest that summertime Arctic temperatures during the early Pliocene epoch (3.5 million to 4 million years ago) may have been a staggering 18 to 28 degrees Fahrenheit warmer than today. And these ancient fossils, harvested from deep within the Arctic Circle, may have once lived in an environment in which the polar ice cap melted completely during the summer months. (more…)
*General Social Survey Also Shows That Happiness Takes A Hit Because of Personal Finances*
Chicago — A recently released report of the General Social Survey, conducted by NORC at the University of Chicago, shows that for the first time since 1972, more Americans say that their financial situation has gotten worse in recent years rather than better. Understandably, also for the first time since 1972, the percentage of Americans saying that they are “not at all” satisfied with their financial situation (31.5%) notably exceeds those saying they are “pretty well” satisfied (23.4%).
