Pennsylvania Governor Tom Corbett has announced that the Department of Environmental Protection (DEP) is accepting applications for projects related to  abandoned mine drainage projects .

You'll have to be a non-profit or a government agency to get government money - the groups most likely to be able to do something on budget are prohibited from applying to get a grant from taxpayers.

Carbon monoxide is known as the "silent killer" because it is imperceptible and lethal. Most homes carry detectors.

We think of it as artificial, due to car exhaust and such, but it is produced naturally in humans and animals, and some medical researchers have even evaluated the gas as a treatment for diabetes, heart attacks, sepsis, and other illnesses. Researchers at Scripps Institution of Oceanography at UC San Diego have studied carbon monoxide's natural characteristics and limitations by studying the gas in one of the world's best divers: the elephant seal.

The West Antarctic Ice Sheet, which holds enough water to raise global seas by several feet, is thinning and computer models predict that the collapse may already have begun. The Thwaites Glacier could disappear in a few hundred years, raising sea levels by nearly 2 feet. That glacier also acts as a linchpin on the rest of the ice sheet, which contains enough ice to cause another 10 to 13 feet of global sea level rise. 

Discussions about science and, to a less extent medicine, often involve optimizing its representation. Various fields discuss how to increase gender or racial parity, while political and handicapped representation is dismissed as choice or even competence.

The high power needed to cut or weld using a laser beam creates its own problem: the beam’s energy deforms the mirrors that focus it. When that happens, the beam expands and loses intensity.

A new type of mirror is being presented at the Optatec trade fair in Frankfurt next week - it can deform itself to correct deformation the laser beams it controls.

Lasers are used in manufacturing to cut materials or weld components together. Laser light is focused to a point using various lenses and mirrors obviously, the smaller the focal point and the higher the energy, the more accurately operators can work with the laser.

Zinc supplements reduce diarrhea, one of the biggest killers of kids under five, and other infections in malnourished children, according to a review in The Cochrane Library. 

Zinc is a micronutrient with important roles in growth and in the immune, nervous and reproductive systems. The human body cannot make it, so it has to come from our diet. It is estimated that more than 1 in 6 people globally are deficient in zinc and that around 1 in every 58 deaths in children under five is related to zinc deficiency. Zinc deficiency is common in Southeast Asia, sub-Saharan Africa and parts of Latin America.
