Researchers at the University at Buffalo and the University of Utah are beginning a clinical trial to test whether aspirin can improve a woman's chances of becoming pregnant and of maintaining a pregnancy to term.

UB's portion of the study is funded by a $2.8 million grant from the National Institute of Child Health and Development.

The trial is aimed at women who have miscarried a pregnancy in the past year.

"In women who have had their first miscarriage, the reasons for losing that pregnancy are in many instances unknown," said Jean Wactawski-Wende, Ph.D., UB associate professor of social and preventive medicine and principal investigator of the UB clinical center.

NASA's Spitzer Space Telescope has captured for the first time enough light from planets outside our solar system, known as exoplanets, to identify signatures of molecules in their atmospheres. The landmark achievement is a significant step toward being able to detect possible life on rocky exoplanets and comes years before astronomers had anticipated.

"This is an amazing surprise," said Spitzer project scientist Dr. Michael Werner of NASA's Jet Propulsion Laboratory, Pasadena, Calif.

Do hard money contributions by interest groups to members of Congress contribute to better quality policy deliberations and outcomes in congressional committees? A new study conducted by political scientist Kevin M.

Scientists from Université Laval’s Faculty of Medicine have succeeded in producing neurons in vitro using stem cells extracted from adult human skin. This is the first time such an advanced state of nerve cell differentiation has been achieved from human skin, according to lead researcher Professor François Berthod. This breakthrough could eventually lead to revolutionary advances in the treatment of neurodegenerative illnesses such as Parkinson’s disease. Berthod and his team described the method used to produce these neurons in a recent issue of the Journal of Cellular Physiology.

The researchers used skin obtained from plastic surgery procedures.

At any given time, most of the roughly 30,000 genes that constitute the human genome are inactive, or repressed, closed to the cellular machinery that transcribes genes into the proteins of the body. In an average cell, only about one in ten genes is active, or expressed, at any given moment, with its DNA open to the cell' transcriptional machinery.

A dynamic cast of gatekeeper enzymes controls this access to the DNA, adding and removing particular molecules to open or close the genome to transcription as needed. Fully explicating the complex interplay among these enzymes and the molecules they manage has been a primary goal for scientists seeking to understand the mechanisms governing gene control.

Drilling is complete on an Alaskan North Slope well, cofunded by the Department of Energy, that could prove to be an important milestone in assessing America's largest potential fossil energy resource: gas hydrate.

Gas hydrate is an ice-like solid that results from the trapping of methane molecules - the main component of natural gas - within a lattice-like cage of water molecules. Dubbed the "ice that burns," this substance releases gaseous methane when it melts.

The size of the global gas hydrate resource is staggering, holding more ultimate energy potential than all other fossil fuels combined, according to the U.S. Geological Survey (USGS).

Researchers at the University of East Anglia are about to embark on an innovative new project to develop computer lip-reading systems that could be used for fighting crime.

The three-year project, which starts next month, will collect data for lip-reading and use it to create machines that automatically convert videos of lip-motions into text. It builds on work already carried out at UEA to develop state-of-the-art speech reading systems.

African and African American women are more likely to die of breast cancer than their white counterparts because they tend to get the disease before the menopause, suggests new research from the University of East Anglia and the Children’s Hospital Boston in collaboration with researchers in the US and Italy.

A racial disparity in mortality rates from breast cancer in the US first appeared in the 1970s coinciding with the introduction of mammography.
