US control strategies may make flu epidemics worse, UCLA study shows

... The model Blower's team developed is inspired by game theory, used in economics to predict how non-communicating, selfish individuals reach a collective behavior with respect to a common dilemma by adapting to what they think are other people's decisions. The group modeled each individual's strategy for...

New species of snapper discovered in Brazil

A popular game fish mistaken by scientists for a dog snapper is actually a new species discovered among the reefs of the Abrolhos region of the South Atlantic Ocean. The international science journal Zootaxa announced the discovery of Lutjanus alexandrei, a new sn...

Racing neurons control whether we stop or go

In the children’s game "red light green light," winners are able to stop, and take off running again, more quickly than their comrades. New research reveals that a similar race goes on in our brains, with impulse control being the big winner. "The research provides new in...

MIT device draws cells close -- but not too close -- together

On a popular children's game participants stand as close as possible without touching. But on a microscopic level, coaxing cells to be very, very close without actually touching one another has been among the most frustrating challenges for cell biologists. Now MIT researchers ...

Scientists crack genetic secrets of human egg

...computer analysis began. In a highly sophisticated game of match, every gene in the egg that was found in other tissues was eliminated, so that only unique genes remained. Cibelli said that the team identified 5,331 human genes that are overexpressed in the egg. Of those, 1,430 are mysteries - their fun...

Hopkins researchers discover how brain protein might control memory

...re, the stronger the memory. Like the childhood game called Telephone, where one person taps her neighbor and whispers a message that is passed on in similar fashion to the next person in line, nerve cells connect and "talk" to each other by relaying messages - usually by passing small chemicals - from...

Distinguishing friend from foe in the battle against cancer

...dy, however, suggests that taking NF-kB out of the game would make rapamycin less "friendly." "A major problem of chemotherapy is that sooner or later cancer cells develop resistance, which requires higher and higher doses of chemotherapeutics," observes Verma, who is also an American Cancer Society prof...

Everything in its place: Researchers identify brain cells used to categorize images

...nts, monkeys were taught to play a simple computer game in which they grouped members of a set of visual motion patterns into one of two categories. Freedman and senior author John Assad, PhD, HMS associate professor of neurobiology, then monitored the activity of neurons in two interconnected brain areas...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

... have evolved together over millions of years in a game of one-upmanship that, often as not, left humans sick or worse. Now, a University of California, Berkeley, researcher has shown that viruses - in this case, a benign one - can be forced to evolve in ways to benefit humans. The adeno-associated viru...

Scientists discover dozens of new species in 'Lost World' of western New Guinea

...vast jungle tract. These people told the team that game was hunted in abundance within an hour's walk of the village. Such abundance of food and other resources means the mountain range's interior ?more than 300,000 hectares of old growth tropical forest ?remains untouched by humans, and the entire Foja...

Cholesterol gets 'thumbs up' for role in digit development

Eleven seconds before volunteers played the game -- discriminating the direction of a field of moving dots -- scientists showed them a hint: an arrow pointing to where the moving dots were likely to appear. The dots were visible only for one-fifth of a second and therefore were easy to miss if a su...
