Seeing below the surface: Ultra-thin, high-speed detector captures unprecedented range of light waves Posted: 07 Sep 2014 03:17 PM PDT Research could lead to light detectors that can see below the surface of bodies, walls, and other objects, with applications in emerging terahertz fields such as mobile communications, medical imaging, chemical sensing, night vision, and security.

Dynamic duo takes out cellular trash: Research finds how dead cells are removed from body Posted: 07 Sep 2014 03:06 PM PDT Scientists have identified how immune cells use two critical receptors to clear dead cells from the body, pointing the way to new autoimmune and cancer therapies. "This basic research focus allowed us to discover a completely new aspect of immune regulation that no one -— including any immunologist—had known about before," said one researcher.

Flour identified as main cause of occupational asthma in France Posted: 07 Sep 2014 05:49 AM PDT Flour has been identified as the main cause of occupational asthma in France, closely followed by cleaning products. The research, which is the largest of its kind to be undertaken in France, aimed to understand who was most affected by the condition and what the main causes were.

Banked blood grows stiffer with age, study finds Posted: 05 Sep 2014 08:39 AM PDT It may look like fresh blood and flow like fresh blood, but the longer blood is stored, the less it can carry oxygen into the tiny microcapillaries of the body, says a new study. Using advanced optical techniques, the researchers measured the stiffness of the membrane surrounding red blood cells over time. They found that, even though the cells retain their shape and hemoglobin content, the membranes get stiffer, which steadily decreases the cells' functionality.

Polyester clothes stink after exercise; cotton, not so much Posted: 03 Sep 2014 01:36 PM PDT Polyester clothes smell worse than cotton, following intensive exercise by their wearers, because bacteria that cause odor grow better on polyester, according to research. Freshly secreted sweat has little odor, because the long-chain fatty acids the axillaries secrete are too big to be volatile, says the first author. Bacteria break these, however, as well as hormones and sulfur compounds, down to waftable sized, odoriferous molecules.

Drinking too much water can be fatal to athletes Posted: 02 Sep 2014 11:32 AM PDT The recent deaths of two high school football players illustrate the dangers of drinking too much water. Exercise-associated hyponatremia can cause muscle cramps, vomiting, seizures and unconsciousness.
