A transparent cornea is essential for vision, which is why the eye has evolved to nourish the cornea without blood vessels. But for millions of people around the world, diseases of the eye or trauma spur the growth of blood vessels and can cause blindness.

According to cost analysis for the legislation compiled by the Humane Society of the United States, the majority of cost-savings from GAPA – 76% – would result from ending federal grants for projects involving chimpanzees.  Of the “nearly $30 million saved annually” over $22 million reflects funds committed to support research projects that involve chimpanzees and are funded by the National Institutes of Health (NIH).

The spread of breast cancer is responsible for more than 90 percent of breast cancer deaths. Now, the process by which it spreads -- or metastasizes -- has been unraveled by researchers at Johns Hopkins.  Reporting in two papers, the researchers have discovered the switch that enables breast cancer cells to travel to and be received in the lungs.

A landmark study in mice identifies a biological mechanism that could help explain how tobacco products could act as gateway drugs, increasing a person's future likelihood of abusing cocaine and perhaps other drugs as well, according to the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. The study is the first to show that nicotine might prime the brain to enhance the behavioral effects of cocaine.

A new therapy being studied in non-human primates by researchers at Wake Forest Baptist Medical Center and colleagues is demonstrating promise as a potential tool for combating cardiovascular disease by increasing good cholesterol and lowering triglycerides in the blood.  Supported by the National Institutes of Health and the Canadian Institutes of Health Research, the preclinical findings appear in this week’s issue of the journal Nature

Salmon, a natural source of omega-3. Professor Breier, who leads an international research team, says omega-3s are especially beneficial for health in ageing because they improve carbohydrate and fat metabolism. His research found a diet high in omega-3 fatty acids helps to burn metabolic fuels (glucose and fat) better, and can regulate energy storage across different tissues.

In a development that sheds new light on the pathology of Alzheimer’s disease (AD), a team of Whitehead Institute scientists has identified connections between genetic risk factors for the disease and the effects of a peptide toxic to nerve cells in the brains of AD patients.

Pythons are known for their enormous appetites. In a single meal they can devour animals at least as big as they are — deer, alligators pigs and house pets, for example.  Equally remarkable is what happens inside the python as it digests its prey.

The pigmented cells called melanocytes aren't just for making freckles and tans. Melanocytes absorb ultraviolet light, protecting the skin from the harmful effects of the sun. They also are the cells that go haywire in melanoma, as well as in more common conditions as vitiligo and albinism.Naturally, researchers would love to study melanocytes in the laboratory. There's just one problem -- melanocytes from adult skin don't grow very well in the lab.

Scientists working at a secured lab in Montana say a human antibody proved highly effective in guarding against a rare but highly lethal virus in a primate study. Investigators injected the deadly Hendra virus--which has killed about half of the people infected by it--in 14 African monkeys. Twelve of those monkeys were treated with the m102.4 antibody and lived. The two untreated monkeys both died.
