Gambling monkeys give insight into neural machinery of risk

... we made the task more interesting by changing the color of the lights on each trial, the monkeys didn't care anything about it." In fact, when the researchers made the average payoff for the risky target less than for the safe target, "we found that they still preferred the risky target," said Platt. "B...

MSU researchers receive $4 million grant to uncover gene functions

...culture. The chloroplast gives green plants their color and carries out photosynthesis and produces oxygen. It can be thought of as the world's life-support system. It is an attractive target for biotechnology because it produces many different molecules important to agriculture and human health, such as ...

Aloe vera coating may prolong freshness, safety of fruits and vegetables

... grapes were firmer, had less weight loss and less color change than the untreated grapes, measures which correspond to higher freshness, they say. A sensory panel (10 people) evaluated the quality of both the untreated and the gel-treated grapes by consuming some of the grapes. They found that the gel-tr...

'Underground' tunnels discovered as means for communication between immune system cells

...arance of the thin membranes, there were bursts of color indicative of calcium flux. Given their earlier results, the researchers anticipated that by repeating the experiment with macrophages there'd be no response. But as luck would have it, the microscopic bacteria sample somehow got clogged inside the t...

New technique could alter field of mouse genetics

...escent protein and an enzyme that changes the coat color of a white mouse to grey or black. The transposon acts as a genetic beacon, so researchers can easily track its location without having to sequence the entire genome, as can happen with the chemical mutagen technique. In three months, the two gradua...
