Halloween is just around the corner, and some people will celebrate by watching scary movies about brain-eating zombies. But even more frightening are real-life parasites that feed on the human brain, and they can be harder to kill than their horror-movie counterparts. Now, researchers have developed silver nanoparticles coated with anti-seizure drugs that can kill brain-eating amoebae while sparing human cells. The researchers report their results in ACS Chemical Neuroscience.

A newly published scientific paper indicates that occupational safety and daily day performance in 7 out of 10 workers, from several European industries, is negatively affected by a combination of heat stress and failure to maintain water balance. The study combines field observations and motor-cognitive testing in the lab, and was conducted by the Pan-European Heat-Shield project coordinated by researchers from Department of Nutrition, Exercise and Sports at University of Copenhagen.

Insect repellents containing picaridin can be lethal to salamanders. So reports a new study published today in Biology Letters that investigated how exposure to two common insect repellents influenced the survival of aquatic salamander and mosquito larvae.

Men who eat plenty of fermented dairy products have a smaller risk of incident coronary heart disease than men who eat less of these products, according to a new study from the University of Eastern Finland. A very high consumption of non-fermented dairy products, on the other hand, was associated with an increased risk of incident coronary heart disease. The findings were published in the British Journal of Nutrition.

Scientists at Indiana University found high levels of a previously unsuspected pollutant in homes, in an electronic waste recycling facility and in the natural environment. People are likely to be exposed to this pollutant by breathing contaminated dust or through skin contact.

For the first time – in Norway and internationally – researchers have looked at the direct correlation between brain size and cancer risk in adults.

Cleaning up or replacing coal-fired power plants that lack sulfur pollution controls could help Texans breathe cleaner, healthier air, according to researchers at Rice University.

Up to 13% of US beekeepers are in danger of losing their colonies due to pesticides sprayed to contain the Zika virus, new research suggests.

Blood pressure readings of 130/80 millimeters of mercury (mm Hg) or higher taken at home can be used to diagnose hypertension in white, black and Hispanic U.S. adults, according to new research in the American Heart Association’s journal Hypertension.

Heat stress affects the health of workers and reduces the work productivity by changing the ambient working environment thus leading to economic losses. How to quantify the impact of heat stress on work productivity has remained an issue to the scientific research and policy-making.
