Packing more digital images, music, and other data onto silicon chips in USB drives and smart phones is like squeezing more strawberries into the same size supermarket carton. The denser you pack, the quicker it spoils. The 10 to 100 gigabits of data per square inch on today’s memory cards has an estimated life expectancy [...]

Thank parasites for making some of our immune proteins into the inflammatory defenders they are today, according to a population genetics study in the Journal of Experimental Medicine. The study also suggests that you might blame parasites for sculpting some of those genes into risk factors for intestinal disorders.
In an advance toward preventing car windshields and eyeglasses from fogging up, researchers in China are reporting development of a new way to make raspberry-shaped nanoparticles that can give glass a permanent antifogging coating.
Psychologists and computer scientists have found that gender is less important than head motion in the nonverbal dynamics of how people converse.

Scientists have studied the El’gygytgyn meteorite impact crater in Arctic Siberia. They found, from analyses of the drill cores, new information about the formation of the impact crater, as well as information they can use more fully to understand the climate history of the Arctic.
Long considered a “muscle” disorder, Pompe disease may have a previously unknown neural component. In mouse models of the disease, researchers have discovered that signals from the spinal cord are too weak to reach the diaphragm — the muscle that controls breathing. The finding suggests that therapies to treat the disease will need to take [...]
