Using IBM’s Crowdsourced Supercomputer, Harvard Rates Solar Energy Potential of 2.3 Million New Compounds

White House Applauds Citizen Science, Big Data Initiative

CAMBRIDGE, MA – 24 Jun 2013: The search for more versatile and less expensive materials for solar energy received a boost today as Harvard launched a free database that catalogues the suitability of 2.3 million organic, carbon compounds for converting sunlight into electricity.

Harvard’s Clean Energy project — which screened the molecules using World Community Grid, an IBM-managed virtual supercomputer that harnesses the surplus computer power donated by volunteers — is believed to be the most extensive investigation of quantum chemicals ever performed. (more…)

Roman Seawater Concrete Holds the Secret to Cutting Carbon Emissions

Berkeley Lab scientists and their colleagues have discovered the properties that made ancient Roman concrete sustainable and durable

The chemical secrets of a concrete Roman breakwater that has spent the last 2,000 years submerged in the Mediterranean Sea have been uncovered by an international team of researchers led by Paulo Monteiro of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), a professor of civil and environmental engineering at the University of California, Berkeley.

Fat cells in breast may connect social stress to breast cancer

Local chemical signals released by fat cells in the mammary gland appear to provide a crucial link between exposure to unrelenting social stressors early in life, and the subsequent development of breast cancer, researchers from the University of Chicago report in the July 2013 issue of the journal Cancer Prevention Research.

Some forms of stress exposure may be associated with an increased risk of certain types of aggressive breast cancer. But the mechanisms linking the biology of social stress to cancer have been hard to identify. To unravel that mechanism, the researchers looked for differences between mice raised in small groups and those that grow up in an isolated setting—an established model of chronic stress without social supports.

Youth bullying because of perceived sexual orientation widespread and damaging

Bullying because of perceived sexual orientation is prevalent among school-aged youths, according to a study led by Donald Patrick, professor of health services at the UW School of Public Health.  The study was published online May 16 in the American Journal of Public Health.

The research team analyzed responses collected in a 2010 Washington state survey of more than 24,000 public school students in grades eight through 12. The study found that 14 percent, 11 percent and 9 percent of male students in grades 8, 10, and 12 respectively reported being bullied because of perceived sexual orientation. For female students in those grades, the numbers were 11 percent, 10 percent and 6 percent respectively. (more…)

How did a third radiation belt appear in the Earth’s upper atmosphere?

Since the discovery of the Van Allen radiation belts in in the Earth’s upper atmosphere in 1958, space scientists have believed that these belts consisted of two doughnut-shaped rings of highly charged particles — an inner ring of high-energy electrons and energetic positive ions, and an outer ring of high-energy electrons.

UMass Amherst Survey Shows Widespread Public Opposition to ‘Killer Robots,’ Support for New Ban Campaign

Active and former military among those most opposed to autonomous weaponry

AMHERST, Mass. – The results of a new survey by the University of Massachusetts Amherst show that a majority of Americans across the political spectrum oppose the outsourcing of lethal military and defense targeting decisions to machines. The opposition to autonomous weaponry is bipartisan, with the strongest opposition on the far left and far right, and among active and former members of the military.
