A new water filter can remove toxic heavy metal ions and radioactive substances in just one pass.

Over the past ten years in the United States, unconventional gas and oil drilling using hydraulic fracturing, or fracking, has experienced a meteoric increase. Since well drilling requires an influx of water, materials and workers into yotherwise rural and remote areas, the question has been: could air, water and noise pollution negatively impact on the health of nearby residents?

As the world warms, animals and plants will shift their ranges to keep pace with their favoured climate. While the changing distributions of species can tell us how climate change is affecting the natural world, it may also have a direct impact on us.

Research worldwide shows that environmentally-friendly buildings are much better for the health of the people who live and work in them, as well as for the Earth.

We have known for some time the people suffering from schizophrenia and other psychoses smoke more than the general population. The explanation that is usually offered is the so-called “self-medication hypothesis”

A new study finds quantifiable evidence that walking in nature could lead to a lower risk of depression. “These results suggest that accessible natural areas may be vital for mental health in our rapidly urbanizing world,” says coauthor Gretchen Daily, professor in environmental science and a senior fellow at the Stanford Woods Institute for the Environment.

In a quest for a perfect tan, many people – especially young white women between age 18 and 25 – may head to a tanning salon, using tanning booths, sunbeds and sunlamps to kick-start their tan. Others (including people who are more prone to burn instead of tan) may head to the salon to slowly develop a “base tan,” with the mistaken belief that it will prevent a sunburn.

The article in The Australian by Liberal Democrat senator David Leyonjhelm highlighted some very good points about wind turbine noise and its effect on people living near them. People are complaining of a range of health related problems and are attributing them to wind turbines. The question is: what is the cause of these health problems?

It’s time to pay attention to a startling stealth killer. What’s the leading cause of death in low- and middle-income countries?

Today, chemicals comprise the backbone of our modern lifestyle and are the largest sector of our economy. We generate 300 billion pounds of synthetic chemicals each year in the U.S. alone, and an average American uses more than 1,500 pounds of chemical products. Synthetic chemicals are poisoning our bodies from the moment of conception. What are we going to do about it?

Office workers who are exposed to natural light sleep better and are more active compared to workers in windowless offices. Employees with windows in the workplace received 173 percent more white light exposure during work hours and slept an average of 46 minutes more each night.

Hugo and Ross Turner are a pair of intrepid twins currently on an expedition to Greenland. One of them, Ross, is using the same style of equipment and facilities used by Ernest Shackleton 100 years ago in his famous Endurance expedition to Antarctica. He’s having an early 20th century polar expedition diet and pulling a 1900s-style sled.

Scientists and government regulators have long identified many common substances that are neurotoxic in high concentrations, including lead and mercury, and have worked to minimize harm to human communities. But there are many chemicals that may affect the human central nervous system and brain functioning that have not been fully tested, and scientists continue to expand the list of harmful substances.

Last week, the Mercury and Air Toxics Standards was finalized and will protect millions of families and, especially, children from air pollution. Before this rule, there were no national standards that limited the amount of mercury, arsenic, chromium, nickel and acid gases power plants across the country could release into the air we breathe.......

by Sondra Kornblatt. Women show more susceptibility to toxins. On one hand, women’s bodies have more fat, where toxins accumulate, so women are four times more likely to exhibit symptoms of chemical sensitivity than men.......

Many older people in the U. S. population were chronically exposed to lead from paint and gasoline prior to the 1980s. To date, most of the research on lead and cognitive functioning in older age has focused on men, despite the fact that women live longer on average and therefore may be more likely to develop dementia over the course of their life span.

The idle fields are illuminated by lights from his house, where several men bend intently over a low wooden table as they pore over satellite photographs and contour maps.

A low-cost vaccine against the dengue virus showed promise in an early-stage clinical trial. With further development, the vaccine may help ease the burden of dengue fever in developing countries....
