A new study in the Proceedings of the National Academy of Sciences provides new evidence and support for a theory introduced in 2007 that suggested a comet may have exploded over Canada 12,900 years ago (the Younger Dryas Boundary), killing off the Clovis people and large animals and sending the earth back into an ice age. It refutes a study in 2009 that failed to replicate the findings of the 2007 study. The key findings in this new study resulted from sampling done at UofSC's archaeological site known as Topper.
Stress has long been pegged as the enemy of attention, disrupting focus and doing substantial damage to working memory — the short-term juggling of information that allows us to do all the little things that make us productive.
Election turnout among young people of color, including African Americans, Latinos and Native Americans, may drop by nearly 700,000 voters in states with new photo ID laws, a decline that could impact presidential contests in battleground states, a study suggests.
Data released by the U.S. Census Bureau today show that, after increasing since 2008, the poverty rate for the U.S. remained stable at 15 percent between 2010 and 2011. In Washington state, the estimated poverty rate increased from 11.5 percent (774,000 residents) to 12.5 percent (854,000 residents) between 2010 and 2011.
Many high-achieving students experience math anxiety at a young age — a problem that can follow them throughout their lives. In a study of first- and second-graders, researchers found that students report worry and fear about doing math as early as first grade. Most surprisingly math anxiety harmed the highest-achieving students.
AstraZeneca and the Broad Institute in Cambridge, Massachusetts today announce a collaboration to identify new chemical compounds targeting bacterial and viral infections that could speed the development of new antibacterial and antiviral drugs.
Less than half of community-based substance abuse treatment programs in the United States currently make HIV testing available on-site or through referral. A new study led by researchers at Weill Cornell Medical College shows the cost-effectiveness of integrating on-site rapid HIV testing into drug treatment programs.
As many as a quarter of Medicare recipients spend more than the total value of their assets on out-of-pocket health care expenses during the last five years of their lives, according to researchers at Mount Sinai School of Medicine. They found that 43 percent of Medicare recipients spend more than their total assets minus the value of their primary residences. The findings appear online in the current issue of the Journal of General Internal Medicine.
Name calling is a petty task for today’s bully. Instead they’re preying on food allergic children, stuffing peanut butter cookies in lockers and turning bullying into a possible death defying nightmare.

The nation’s obesity epidemic reaches far beyond adults and children to our pets, who share our homes and often our dietary habits and lack of exercise. To address this, the Cummings School of Veterinary Medicine at Tufts University has created the nation’s first obesity clinic geared especially for pets and overseen by a full-time, board-certified veterinary nutritionist.
