Key finding sheds new light on common bleeding disorders

A simple cut to the skin unleashes a complex cascade of chemistry to stem the flow of blood. Now, scientists at Washington University School of Medicine in St. Louis have used evolutionary clues to reveal how a key clotting protein assembles. The finding sheds new light on common bleeding disorders.

Humans and zebrafish share mechanisms that regulate the circadian system

Circadian rhythms - the natural cycle that dictates our biological processes over a 24-hour day - does more than tell us when to sleep or wake. Disruptions in the cycle are also associated with depression, problems with weight control, jet lag and more. Now Prof. Yoav Gothilf of Tel Aviv University's Department of Neurobiology at the George S. Wise Faculty of Life Sciences is looking to the common zebrafish to learn more about how the human circadian system functions.

Study investigates mercury deposits in industrialized city soil

Indianapolis, St. Louis, Detroit, Buffalo, Richmond and Providence - cities scattered across the eastern half of the United States - have something in common, all have coal-fired power plants. A new study from the School of Science at Indiana University-Purdue University Indianapolis is among the first to investigate mercury deposits in industrialized city soil near this type of facility.

Food4Me project to investigate potential of personalised nutrition

When the human genome sequence was launched in 2000, it introduced the possibility of personalisation in health care. Such personalisation can be applied to nutrition, a key health determinant, to create a diet tailored specifically for an individual, according to their individual physical and genetic make-up. Food4Me is a new, EU (FP7) funded project investigating the potential of this personalised nutrition.

Software program could protect Florida's lakes, rivers from pollutants

As a young scholar, Fernando Rios loved science and computer programming equally. So when Rios - who holds a bachelor's degree in physics from Canada's University of Waterloo - went looking for a graduate program, he discovered the Department of Scientific Computing at Florida State University, which has about 35 graduate students and launched a new undergraduate program of computational sciences in fall 2010.

Healthy diet might help reduce risk of macular degeneration

Eating a diet high in vitamin D, as well as the nutrients betaine and methionine, might help reduce the risk of macular degeneration, according to new research conducted by Tufts Medical Center scientists. Their study of identical twins from the US World War II Twin Registry also found that the more a person smoked, the higher their risk of developing macular degeneration.

Zebrafish study uncovers new information about hepatocellular carcinoma

Hepatocellular carcinoma, the most common type of liver cancer, is a leading cause of cancer-related deaths worldwide. Although there are several treatment options available, they are largely unsuccessful because the disease is so poorly understood. Clinical studies of patients with HCC, combined with studies using mice and other animal models, have provided some clues, but many questions about how to diagnose and treat this deadly form of cancer remain.
