Science's Breakthrough of the Year: Watching evolution in action
Evolution has been the foundation and guiding theory of biology since Darwin gave the theory its proper scientific debut in 1859. But Darwin probably never dreamed that researchers in 2005 would still be uncovering new details about the nuts and bolts of his theory -- how does evolution actually work in the world of influenza genes and chimpanzee genes and stickleback fish armor? Studies that fol...Watching the brain switch off 'self'
Everybody has experienced a sense of "losing oneself" in an activity--whether a movie, sport, sex, or meditation. Now, researchers have caught the brain in the act of losing "self" as it shuts down introspection during a demanding sensory task. The researchers--led by Rafael Malach and Ilan Goldberg of the Weizmann Institute of Science reporting in the April 20, 2006, issue of Neuron--say...Catching cancer's spread by watching hemoglobin
In an advance that can potentially assist cancer diagnosis, a new optical technique provides high-resolution, three-dimensional images of blood vessels by taking advantage of the natural multiple-photon-absorbing properties of hemoglobin, the red-blood-cell molecule that carries oxygen throughout the bloodstream. The research will be presented in Baltimore at CLEO/QELS, May 6 ?May 11. The...Watching Evolution Happen - Evolving Healthcare Technology Spies Big Change
If Wisconsin can be said to have anything going for it in the digital age, its the confluence of its mushrooming health care and information technology sectors. The first-ever Evolving Healthcare Technology Conference, being held Friday at the Medical College of Wisconsin (MCW) in Milwaukee, is hoping to expose the breadth of whats happening at that crossroad, as well as give participant...Watching television for long hours could lead to agressiveness
Researchers claim that children who watch television for long hours are more likely to be agitated.The research was carried out by Jeffrey Johnson, of Columbia University// and the New York State Psychiatric Institute. His team tracked more than 700 children through adolescence to adulthood. They found that those who had watched one or more hours of television a day appeared much more...Watching television linked to smoking
In the United States smoking is the leading preventable cause of death. Turning off the television could prevent young people from smoking. A new study finds the more an adolescent watches television, the more likely they are to start smoking. //The risk of disease increases the earlier in life one starts to smoke. About 5 million adolescents smoke and that number has been increasing since 1990....Reduce watching TV to prevent Obesity and Diabetes
Researchers at Harvard have found that an active lifestyle with limiting TV time could prevent obesity and type 2 diabetes. In a survey conducted in the US TV watching results in a lower metabolic rate when compared to activities like sewing, playing board games, reading, writing or driving a car. Prolonged TV watching is also linked to obesity in children. The health campaigns are focussed on in...TV watching may turn your child into a bully
A new study on child behavior had pointed out that excessive exposure to television at the early childhood age might make the child indulge in bullying behavior.// A child is considered to be a bully when he repeatedly harasses and attacks other children. Bullying can be done by actual physical attack on others or by verbal assaults, threats, extortion and intimidation. Pare...Study reveals that it is easy for people to learn from watching others learn
A Canadian research team from the University of Western Ontario had found out that it is possible to learn// complex physical actions by observing others. The study used a robot arm to show how to perform complex mechanical tasks to a group of people. When the video of this learning process was shown to a group, they learned to do the same action in less time than the people in the vi...
