An Ohio State University molecular biologist leveraged a supercomputer to help better define the family tree of a group of enzymes that have been implicated in a wide range of human diseases and are important targets for anti-cancer therapies.

Along with several OSU colleagues, Rebecca S. Lamb, Ph.D., an assistant professor of Molecular Genetics, recently analyzed the evolutionary history of the poly(ADP-ribose)polymerase (PARP) superfamily.

In the first census of its kind, research led by UC Davis and Stanford University found that there are far fewer white sharks off central California than biologists had thought.

The study, published today in the journal Biology Letters, is the first rigorous scientific estimate of white shark numbers in the northeast Pacific Ocean. It is also the best estimate among the world's three known white-shark populations (the others are in Australia/New Zealand and South Africa).

Lent in the Christian tradition is a time of sacrifice and penance. It also is a period of purification and enlightenment. Pain purifies. It atones for sin and cleanses the soul. Or at least that's the idea. Theological questions aside, can self-inflicted pain really alleviate the guilt associated with immoral acts? A new study published in Psychological Science, a journal of the Association for Psychological Science, explores the psychological consequences of experiencing bodily pain.

Chapel Hill, NC – A UNC study released this week in the Journal of Clinical Oncology finds an increasing incidence of squamous cell carcinoma of the oral tongue in young white females in the United States over the last three decades.

CHAMPAIGN, Ill. — Think picking all the top-seeded teams as the Final Four in your March Madness bracket is your best bet for winning the office pool? Think again.

According to an operations research analysis model developed by Sheldon H. Jacobson, a professor of computer science and the director of the simulation and optimization laboratory at the University of Illinois, you're better off picking a combination of two top-seeded teams, a No. 2 seed and a No. 3 seed.

MIDWAY ATOLL — The oldest known U.S. wild bird – a coyly conservative 60 -- is a new mother.

The bird, a Laysan albatross named Wisdom, was spotted a few weeks ago with a chick by John Klavitter, a U.S. Fish and Wildlife Service biologist and the deputy manager of the Midway Atoll National Wildlife Refuge.

NEW YORK CITY (March 7, 2011)— Paul Tesar, PhD, of Case Western Reserve University, a member of the inaugural class of The New York Stem Cell Foundation – Robertson Investigators, published his research on the ability to isolate epiblast stem cells from preimplantation mouse embryos. This research enhances our understanding of the many forms of pluriportent stem cells that scientists use for researching so many debilitating diseases.

COLUMBIA, Mo. ADAM-12 is not only the name of a 1970's television police drama – it's also the gene that University of Missouri researchers believe could be an important element in the fight against cancer, arthritis, and cardiac hypertrophy, or thickening of the heart's walls.

FOR IMMEDIATE RELEASE from the UNIVERSITY OF TORONTOMarch 8, 2011

TORONTO, ON – Communication technologies that help people stay connected to the workplace are often seen as solutions to balancing work and family life. A new study, however, suggests there may be a "dark side" to the use of these technologies for workers' health – and these effects seem to differ for women and men.

Bethesda, Md. (Mar. 8, 2011) -- What do you have when you line up a martial artist, acrobatic gymnast, police officer, firefighter, NASCAR driver, and NFL running back? "Watson," the IBM super-computer that recently routed humanity's best on Jeopardy might have guessed the answer was "the Village People," to which host Alex Trebek could have replied, "Sorry. The answer we were looking for is 'Batman'." At least that is the correct answer for physiologist E. Paul Zehr.

COLUMBUS, Ohio – Passive news reporting that doesn't attempt to resolve factual disputes in politics may have detrimental effects on readers, new research suggests.

The study found that people are more likely to doubt their own ability to determine the truth in politics after reading an article that simply lists competing claims without offering any idea of which side is right.

Why should we care about butterflies and moths? Thanks to butterflies, bees, birds, and other animal pollinators, the world's flowering plants are able to reproduce and bear fruit. That very basic capability is at the root of many of the foods we eat. And, not least, pollination adds to the beauty we see around us.

COLLEGE PARK, Md. – It took nearly a decade before University of Maryland researchers were allowed to talk about their work identifying the anthrax strain used in the 2001 deadly letter attacks. But now, they and the other key members of the high-powered science team have published the first account of the pioneering work, which launched the new field of "microbial forensics" and gave bioterrorism investigators a way to "fingerprint" bacteria.

In the thick of whale season, researchers from Hawai'i Institute of Marine Biology (HIMB) and the National Oceanic and Atmospheric Administration (NOAA) shed new light on the wintering grounds of the humpback whale. The primary breeding ground for the North Pacific was always thought to be the main Hawaiian Islands (MHI). However, a new study has shown that these grounds extend all the way throughout the Hawaiian Archipelago and into the Northwestern Hawaiian Islands (NWHI), also known as Papahānaumokuākea Marine National Monument (PMNM).

A study has gained new insight into the minds of domestic hens, discovering, for the first time, that domestic hens show a clear physiological and behavioural response when their chicks are mildly distressed.

The research by academics at the University of Bristol's Animal Welfare and Behaviour research group, and funded by the BBSRC Animal Welfare Initiative, is published online in the Proceedings of the Royal Society B.
