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.

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…)
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.

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.

At the Advanced Light Source, Berkeley Lab scientists join an international team to control spin orientation in magnetic nanodisks
“We spent 15 percent of home energy on gadgets in 2009, and we’re buying more gadgets all the time,” says Peter Fischer of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). Fischer lets you know right away that while it’s scientific curiosity that inspires his research at the Lab’s Advanced Light Source (ALS), he intends it to help solve pressing problems.
“What we’re working on now could make these gadgets perform hundreds of times better and also be a hundred times more energy efficient,” says Fischer, a staff scientist in the Materials Sciences Division. As a principal investigator at the Center for X-Ray Optics, he leads ALS beamline 6.1.2, where he specializes in studies of magnetism. (more…)
