Games Aren't Fun
Psychologists say we play video games to enhance our feelings of autonomy and competence -- not because they're "fun." In Game|Life. Knee Arthritis Linked To Lung Cancer
Arthritis of the knee may be the first sign of a type of lung cancer that is hard to treat in heavy smokers, suggests new research. The researchers reviewed the case notes of all patients with rheumatic disorders, diagnosed at one tertiary referral centre over six years. Close-up photos of dying star show our sun's fate
About 550 light-years from Earth, a star like our Sun is writhing in its death throes. Chi Cygni has swollen in size to become a red giant star so large that it would swallow every planet out to Mars in our solar system. Moreover, it has begun to pulse dramatically in and out, beating like a giant heart. New close-up photos of the surface of this distant star show its throbbing motions in unprecedented detail. The Underground Railroad
Explores the system that helped escaped African slaves in the United States to reach freedom safely.

Also includes educational activities for K-12 students, a discussion forum, and a list of resources and websites for further study. From National Geographic. Increased Availability Of Genetically Altered Mice To Aid Studies Of H
The National Institutes of Health will provide $4.8 million to establish and support a repository for its Knockout Mouse Project. This award is the final component of a more than $50 million initiative to increase the availability of genetically altered mice and related materials. Personal Genomes: Mainstream In Five Years, But Who Should Have Access
Imagine this: you visit your clinician, undergo genetic testing and then you are handed a miniature hard drive containing your personal genome sequence, which is subsequently uploaded onto publicly accessible databases. This may sound like science fiction, but it is scientific fact, and it is already happening. It may not be long before companies are able to offer Facebook-like social networking services centred around our genomes. In an article published in the journal Science, University of Alberta researcher Tim Caulfield and co-authors highlight the need to proceed cautiously when it comes to personal genomics. Antidepressant Warnings Associated With Decreased Prescription Rates A
Regulatory warnings regarding the risk of suicidal thoughts and behaviors appear to be associated with reductions in the number of antidepressant medication prescriptions among children and adolescents covered by Tennessee's expanded Medicaid program, according to a report in the July issue of Archives of Pediatrics &Adolescent Medicine, one of the JAMA and Archives journals. Teenagers programmed to take risks
Risk-taking peaks in adolescence, according to scientists in the UK. In a new study, children, adolescents and adults aged 9-35 years chose between risky and safe options in a computer gambling game. Scientists found that the teenagers took the most risks compared with the other groups, with the most risky behaviour seen in 14-year olds. Difference Between Fish And Humans: Century-old Developmental Question
Embryologists have helped solve an evolutionary riddle that has been puzzling scientists for over a century. They have identified a key mechanism in the initial stages of an embryo's development that helps differentiate more highly evolved species, including humans, from less evolved species, such as fish. Treating Drug Addiction
There is not much in the plant world that people have not sniffed, snorted, smoked, rubbed in, injected or attempted to get inside their bodies in other ways in the hope of eliciting someone kind of magical response. The well-known plants that gave a positive result in the primitive tests - the coca plant, poppies, marijuana, tobacco, betel trees, coffee beans - have since grown infamous leaving the air heavy with their tragic scent in so many places.
