The use of asbestos continues to increase in Asia despite clear health hazards. A recent Respirology review notes that with approximately 4.3 billion people and a growing population, Asia will likely see a large crop of asbestos-related lung diseases in the next few decades. Some of the cases will be benign, but it is likely that there will be many cases of mesothelioma and lung cancer.

Efforts are needed to improve the recognition and diagnosis of asbestos-related lung diseases, and government and non-government groups must cooperate to take steps to prevent them.

A broccoli variety modified to have two to three times more of the naturally occurring compound glucoraphanin, which is linked to antioxidants and other health benefits, also reduces blood LDL-cholesterol levels by around 6%, according to results of human trials. 

Glucoraphanin is thought to work by helping maintain cellular metabolism. Mitochondria, the energy factories of the cell, convert sugars and fats into energy, but if they aren't working efficiently, one response is to channel excess into cholesterol.  

Light is a useful tool for quantum communication, but it has one major disadvantage - it travels at the speed of light and sometimes things need to be kept in place, or at least slowed down.

Like with trains all sharing a track, you can't have one express line with no brakes for very long. 

A team researchers has demonstrated they can put the brakes on light, and not in some arcane quantum system but rather in glass fiber networks we are already using today. By coupling atoms to glass fibers light was slowed down to train speed - 90 miles per hour - and they even managed to bring the light to a complete stop and to retrieve it again later.

Life has adapted to all sorts of extreme environments on Earth, among them, animals like the deer mouse, shimmying and shivering about, and having to squeeze enough energy from the cold, thin air to fuel their bodies and survive.

In a new paper, Scott, Cheviron et al., have examined the underlying muscle physiology from a group of highland and lowland deer mice. Peromyscus maniculatus - deer mice - were chosen because they exhibit the most extreme altitude range of any North American mammal, occurring below sea levels in Death Valley to more than 4,300 meters high in the mountains. 

Researchers have taken a step toward using the implantation of stem cell-generated neurons as a treatment for Parkinson's disease.

 Parkinson's, which affect as many 10 million people in the world, is linked to a depletion of dopamine-producing neurons in the brain. Current treatments include medications and electrical implants in the brain which cause severe adverse effects over time and fail to prevent disease progression. Several studies have indicated that the transplantation of embryonic stem cells improves motor functions in animal models but the procedure has shown to be unsafe, because of the risk of tumors upon transplantation. 

Clearing grasslands to make way for biofuels may seem counterproductive, but University of Wisconsin-Madison researchers show in a study today (April 2, 2015) that crops, including the corn and soy commonly used for biofuels, expanded onto 7 million acres of new land in the U.S. over a recent four-year period, replacing millions of acres of grasslands.
