Essential for life in higher animals, vitamin D, once linked to only bone diseases such as rickets and osteoporosis, is now recognized as a major player in contributing to overall human health, emphasizes UC Riverside's Anthony Norman, an international expert on vitamin D.

Growing evidence indicates that exposure to irregular patterns of light and darkness can cause the human circadian system to fall out of synchrony with the 24-hour solar day, negatively affecting human health — but scientists have been unable to effectively study the relationship between circadian disruptions and human maladies.

The United Nations has warned that global warming and its effects, including a rise in air and sea temperatures and extreme weather patterns, not only endanger the planet but also pose a "major threat" to human health.

Researchers studying deer mice have discovered evidence to support what mothers everywhere have long suspected: the immune system needs food to function properly.

A new scientific work confirms the beneficial effects of these compounds on human health. And the heart stays young longer

Probiotic bacteria, defined as living microorganisms that have beneficial effects on human health, have been used for the prevention and treatment of a diverse range of disorders. However, the ways in which probiotic bacteria elicit their health effects are not fully understood.

Students on a unique new postgraduate course at The University of Nottingham will get to grips with the biggest public health challenges of the 21st century.

Last week NIP and EPA announced a cooperation to test tens of thousands of chemicals for toxic effects. The work is expected to generate data specific to human health effects of exposure to a store of chemicals.

Polybrominated diphenyl ethers (PBDEs), chemicals used as fire retardants, can be found in numerous items in the home, such as the television, computer, toaster and the sofa. Now, as reported in a KNBC story on Nov. 28, they are being found in alarming concentrations, in human blood and breast milk – a potentially major concern for human health.

As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body’s first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria.

The Environmental Protection Agency (EPA) must make key decisions about how to apply the two major end-of-life statutes to nanotechnology waste in order to ensure adequate oversight for these technologies, concludes a new report from the Wilson Center’s Project on Emerging Nanotechnologies.

A research team led by Carole Thivierge, from Université Laval's Institute of Nutraceutics and Functional Foods, shows that omega-3 fatty acids from fish oil have a positive effect on the metabolism of muscle proteins. This finding, published in a recent edition of the Journal of Physiology, could have significant implications in the fields of animal farming as well as human health.
