PKM-zeta-less adult mice still able to form long-term memories

A study by Johns Hopkins researchers has shown that a widely accepted model of long-term memory formation - that it hinges on a single enzyme in the brain - is flawed. The new study, published in the Jan. 2 issue of Nature, found that mice lacking the enzyme that purportedly builds memory were in fact still able to form long-term memories as well as normal mice could.

Itch-specific nerve cells in skin discovered by John Hopkins scientists

Johns Hopkins researchers have uncovered strong evidence that mice have a specific set of nerve cells that signal itch but not pain, a finding that may settle a decades-long debate about these sensations, and, if confirmed in humans, help in developing treatments for chronic itch, including itch caused by life-saving medications.

Aerobic better than resistance training when it comes to weight and fat loss

A new study led by North Carolina researchers has found that when it comes to weight- and fat loss, aerobic training is better than resistance training. The study is believed to the largest randomized trial to directly compare changes in body composition induced by comparable amounts of time spent doing aerobic and resistant training, or both in combination, among previously inactive overweight or obese non-diabetic adults.
