How skin is wired for touch Compared to our other senses, scientists don't know much about how our skin is wired for the sensation of touch. Now, research reported in the December 23rd issue of the journal Cell, a Cell Press publication, provides the first picture of how specialized neurons feel light touches, like a brush of movement or a vibration, are organized in hairy skin.

Study examines how diving marine mammals manage decompression Any diver returning from ocean depths knows about the hazard of decompression sickness (DCS) or "the bends." As the diver ascends and the ocean pressure decreases, gases that were absorbed by the body during the dive, come out of solution and, if the ascent is too rapid, can cause bubbles to form in the body.

Blood-sucking mosquitoes keep their cool No one likes being bitten by whining mosquitoes, but have you ever considered what the experience is like for them as their cold-blooded bodies fill with our warm blood? Now researchers reporting online on December 15 in Current Biology, a Cell Press publication, have uncovered the mosquitoes' secret to avoiding heat stress: they give up cooling droplets of their hard-won meals.

Super athletic mice are fit because their muscles burn more sugar Muscle performance and fitness are partly determined by how well your muscle cells use sugar as a fuel source. In turn, exercising improves the muscle's ability to take up sugars from the bloodstream and burn them for energy. On the flip side, conditions that reduce physical activity -- such as obesity or chronic disease -- reduce the muscle's capacity to burn sugar.

What I Still Hear: Sounds That Have Disappeared The sounds in our heads are the products of our lives: the tunes we loved, the ads, the jingles, the noises that poured out from the appliances and the living spaces around us. Here are 12 sounds of the times: 6 old and 6 new, to mix and remix. What are the sounds of your life?

Frogs' amazing leaps due to springy tendons Some species of frogs and many other animals are able to jump far beyond what appear to be their capabilities. The trained contestants in the frog-jumping competition in Calaveras County, Calif., come to mind, but even ordinary frogs can leap several times farther than their physiology would seem to allow.

A hormone ensures its future Much of the body's chemistry is controlled by the brain – from blood pressure to appetite to food metabolism. In a study published recently in Developmental Cell, a team of scientists led by Dr. Gil Levkowitz of the Weizmann Institute has revealed the exact structure of one crucial brain area in which biochemical commands are passed from the brain cells to the bloodstream and from there to the bod

Simple gut hormone combo makes our brains think we're full Many of us would love nothing more than to trick ourselves into believing we are full even as our stomachs remain empty. Now, a new brain imaging study reported in the November issue of the Cell Press journal Cell Metabolism suggests there might just be a way. The key is to go with our guts – just two gut hormones, that is.
