BOSTON – Researchers today more than ever focus their work on real-world problems, often times making their research relevant to the public locally, regionally and sometimes nationally. But engaging the public in their research can be a daunting task for researchers both professionally and personally.

The fibrous threads helping mussels stay anchored – in spite of waves that sometimes pound the shore with a force equivalent to a jet liner flying at 600 miles per hour – are more prone to snap when ocean temperatures climb higher than normal.

At the American Association for the Advancement of Science meeting in Boston, Emily Carrington, a University of Washington professor of biology, reported that the fibrous threads she calls "nature's bungee cords" become 60 percent weaker in water that was 15 degrees F (7 C) above typical summer temperatures where the mussels were from.

When it comes to sticking power under wet conditions, marine mussels are hard to beat. They can adhere to virtually all inorganic and organic surfaces, sustaining their tenacious bonds in saltwater, including turbulent tidal environments.

BOSTON -- A controversial component of plastic bottles and canned food linings that have helped make the world's food supply safer has recently come under attack: bisphenol A. Widely known as BPA, it has the potential to mimic the sex hormone estrogen if blood and tissue levels are high enough. Now, an analysis of almost 150 BPA exposure studies shows that in the general population, people's exposure may be many times too low for BPA to effectively mimic estrogen in the human body.

Rose McDermott, professor of political science at Brown University, will discuss the growing field of research that explores possible links between genetics and political preferences at the annual meeting of the American Association for the Advancement of Science (AAAS), the world's largest general scientific society.

To truly understand the mechanisms of natural selection, evolutionary biologists need to shift their focus from present-day molecules to synthesized, ancestral ones, says Shozo Yokoyama, a biologist at Emory University.

Yokoyama will present evidence for why evolutionary biology needs to make this shift at 1:30 pm on Friday, February 15, during the American Academy of Arts and Sciences (AAAS) annual meeting in Boston.

Why is the world so full of "morons" and "degenerates" and what, if anything, can be done to fix them?

These are questions that Robert W. Sussman, PhD, a professor of anthropology in Arts & Sciences at Washington University in St. Louis, will explore Feb. 15 as he addresses the 2013 meeting of the American Association for the Advancement of Science (AAAS) in Boston, Mass. — one of the world's largest gatherings of scientific researchers.

Having diabetes doubles a person's risk of dying after a heart attack, but the reason for the increased risk is not clear. A new University of Iowa study suggests the link may lie in the over-activation of an important heart enzyme, which leads to death of pacemaker cells in the heart, abnormal heart rhythm, and increased risk of sudden death in diabetic mice following a heart attack.

UNIVERSITY PARK, PA. -- Researchers have studied viruses as agents of disease in humans, domestic animals and plants, but a study of plant viruses in the wild may point to a more cooperative, benevolent role of the microbe, according to a Penn State virologist.

"Most of these wild plants have viruses," said Marilyn Roossinck, professor of plant pathology and environmental microbiology and biology, who has examined more than 7,000 individual plants for viruses. "But they don't have any of the symptoms that we usually see in crop plants with viruses."

Recent studies have identified correlations between cigarette smoke-induced microRNA (miRNA) expression and different aspects of lung cancer; however, it is unclear how miRNA expression directly contributes to carcinogenesis. MiRNAs regulate the expression of target genes and can have a significant impact on when and how well different gene products are expressed.

LA JOLLA, CA – February 15, 2013 – Doctors currently struggle to determine whether a breast tumor is likely to shift into an aggressive, life-threatening mode—an issue with profound implications for treatment. Now a group from The Scripps Research Institute (TSRI) has identified a mechanism through which mitochondria, the powerhouses of a cell, control tumor aggressiveness. Based on their findings, the team developed a simple treatment that inhibits cancer progression and prolongs life when tested in mice.

CHARLOTTE, N.C. –Feb. 14, 2013– The pharmaceutical industry's efforts to self-regulate its direct-to-consumer (DTC) advertising are "an industry-sponsored ruse," intended to deflect criticism and collectively block new Federal regulation, a study released today in the Journal of Health Politics, Policy and Law found.

Organic semiconductors hold promise for making low-cost flexible electronics – conceivably video displays that bend like book pages or roll and unroll like posters, or wearable circuitry sewn into uniforms or athletic wear. Researchers have demonstrated the ability to "print" transistors made of organic crystals on flexible plastic sheets, using technology that resembles inkjet or gravure printing.

Wcologists from Umeå University and the Norwegian University of Science and Technology in Trondheim have studied fish communities and fish habitat and reviewed the importance of winter conditions for fish in streams and rivers in cold regions. The findings are now being published in the journal BioScience.

It is well known that winter can be a stressful season for plants and animals in streams and rivers. It is reasonable to assume that more extreme weather conditions are the most taxing, but the ecological significance of this is poorly understood.
