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.

WASHINGTON, DC, March 3, 2011 — Communication technologies that help people stay connected to the workplace are often seen as solutions to balancing work and family life. However, a new study in the March issue of the Journal of Health and Social Behavior 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.

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.

WASHINGTON, D.C. (March 8 2011) -- Researchers at the Instituto de Medicina Molecular in Lisbon, Portugal and the Universidade Federal do Rio de Janeiro (UFRJ), Rio de Janeiro, Brazil, are making major strides toward understanding the life cycle of flaviviruses, which include some of the most virulent human pathogens: yellow fever virus, Dengue virus, and the West Nile Virus, among others.

WASHINGTON, D.C. (March 8 2011) -- Viruses can penetrate every part of the body, making them potentially good tools for gene therapy or drug delivery. But with our immune system primed to seek and destroy these foreign invaders, delivering therapies with viruses is currently inefficient and can pose a significant danger to patients.

Now scientists at the University of Pennsylvania have engineered a virus with potential to solve this problem. They describe the new virus today at the 55th Annual Biophysical Society Meeting in Baltimore, MD.

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.

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.

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.

WASHINGTON, D.C. (March 8, 2011) -- Researchers at the University of Texas Southwestern Medical Center and the University of Texas at Dallas are reporting today at the 55th Annual Biophysical Society Annual Meeting in Baltimore, MD how they are using a novel 3D cell imaging method for studying the complex spatial-temporal dynamics of protein transport, providing a solution to this fundamental problem in cell biology.

People visiting Spain have a high opinion of the price-quality ratio of Spanish hotels. Spanish tourists, on the contrary, complain about the quality of hotels, cleanliness and hospitality in countries such as Italy, Greece and France. This is one of the conclusions of a study carried out by the University of Cádiz (UCA) on tourism in southern Mediterranean countries.

Alexandria, VA – In 1993, "Jurassic Park" thrilled the world with the idea that dinosaurs could be resurrected from bits of DNA preserved in mosquitoes trapped in ancient amber. In the 18 years since the movie came out, scientists have been finding that parts of this scenario are closer to reality than anyone ever imagined: Researchers have found microbes living for tens of thousands - and maybe millions - of years inside salt crystals.

Forget technology. The best prescription for patients with venous leg ulcers is good quality nursing care – and the occasional belly laugh!

A five-year study led from the University of Leeds has shown that ultrasound therapy does nothing to speed up the healing process of leg ulceration – contrary to what had been expected. Traditional methods of nursing care, which are cheaper and easier to deliver, work just as well, the authors conclude.

Research by the University of Liverpool has found that systemic inflammation caused by sepsis can be suppressed by a protein which occurs naturally in a type of roundworm.

Sepsis is a serious inflammatory condition, caused by the body over-reacting to infection. The body becomes overwhelmed by bacteria, setting off a series of reactions that lead to inflammation and clotting. It affects around 20 million people worldwide each year, and accounts for a large proportion of intensive care unit admissions.

Bowel cancer patients whose tumors contain defects in specific DNA repair systems are much less likely to experience tumour recurrence post surgery, results from a major clinical study have demonstrated.

A group of researchers from EPFL's Global Health Institute (GHI) and Inserm (Institut National de la Santé et de la Recherche Médicale, the French government agency for biomedical research) has discovered that a class of chemotherapy drugs originally designed to inhibit key signaling pathways in cancer cells also kills the parasite that causes malaria. The discovery could quickly open up a whole new strategy for combating this deadly disease.
