Imaging pinpoints brain regions that 'see the future'

...y cues, such as getting lost, spending time with a friend or attending a birthday party, participants were asked to recall a related event from their own past; to envision themselves experiencing such an event in their future life; or, to picture a famous celebrity -- specifically former U.S. President Bill...

Racing neurons control whether we stop or go

...avior on a task called the stop signal task with a friend of mine, William Cowan, who is a theoretical physicist, in the 1980s," Logan, Centennial Professor of Psychology, said. Stop signal tasks measure an individual’s ability to stop a planned action, like pressing a key on a keyboard or looking at a targ...

Making mice with enhanced color vision

... "green" they see is the same as the "green" their friend sees can attest to this -- the researchers only tested whether the mice could discriminate among the lights. "Each photoreceptor absorbs a range of wavelengths, but the efficiency changes with wavelength," Nathans explains. "For example, one pho...

Invasive ants territorial when neighbors are not kin

...s appear to use genetic differences to distinguish friend from foe, a finding that helps to explain why these ants form enormous colonies in California. In the December issue of the journal Molecular Ecology, the biologists provide the first data on territorial interactions among Argentine ants in the fi...

New brain-chemistry differences found in depressed women

...e women recalled the death or serious illness of a friend or family member, a past divorce or breakup with a boyfriend, or other major difficulties. They also had their brains imaged during a neutral emotional state. Just before the brain scans, the women also had their blood tested to measure levels of...

Distinguishing friend from foe in the battle against cancer

...l growth. But to cancer cells, rapamycin is both friend and foe. "Rapamycin is not as successful as initially expected in treating cancer," explains Ghosh. "Instead of killing cells, you end up triggering a survival response in them." This study, however, suggests that taking NF-kB out of the game would m...

...phate. Forty years later, Dr. Hamilcar Intengan, a friend of his who now lives in Chicago, recognized the importance of the bones and donated them to The Field Museum. If not for the attention and foresight of these two individuals, science might never have documented what has turned out to be an extremely...

Same mutation aided evolution in many fish species, Stanford study finds

...d that the gene in question, called Eda, is an old friend to laboratory researchers who have found that mutations in the same gene in mice cause altered hair patterns. However, in mice similar alterations can also be created by defects in any one of three different genes. "Based on the mouse work you'd pred...

Plants respond similarly to signals from friends, enemies

Two soil-dwelling strangers ?a friend and a foe ?approach a plant and communicate with it in order to enter a partnership. The friend wants to trade nitrogen for food. The foe is a parasite that wants to burrow in and harm the plant. ...
