A striking new study testing a number of over-the-counter weight loss and sports supplements has found they contain many combinations of stimulants that have either previously been prohibited by the FDA or never approved for human consumption.

Although there already are devices that can detect harmful gases, most of them aren't particularly portable or simple to use. An experimental new tool, however, is about the size of a hypodermic needle – and it could be utilized by anyone, anywhere.

The ingenuity of bacteria keeps surprising scientists. The latest example is a species called Geobacter sulfurreducens, which has now been found to survive exposure to toxic cobalt by building a metal “suit” like a tiny little Iron Man.

Often made from plants, recycled material and various forms of organic matter, bioplastics promise a number of advantages over conventional plastics produced through fossil fuels, but a new study suggests that safety may not be one of them.

Australian researchers have solved the mystery behind the sting of one of the most venomous plants on the planet. The newly discovered neurotoxin explains how Australian stinging trees cause pain that can last for extraordinarily long periods.

Quantum dots have shown promise in solar cells. Now, researchers at Los Alamos National Laboratory (LANL) have developed a new type of quantum dot solar cell that isn’t made with the toxic elements found in most, while maintaining efficiency.

Incorrectly identifying wild mushrooms while foraging can lead to more than an upset stomach, it could prove fatal. Researchers from the USDA's Agricultural Research Service have developed a portable test to help.
