Daniel Tammet is an autistic savant. He can perform mind-boggling mathematical calculations at breakneck speeds. But unlike other savants, who can perform similar feats, Tammet can describe how he does it. Now scientists are asking whether his exceptional abilities are the key to unlock the secrets of autism.
He doesn't calculate these math problems in his head. He is immediately shown the answer. It started at the age of three after an epileptic seizure.
Since his epileptic fit, he has been able to see numbers as shapes, colours and textures. The number two, for instance, is a motion, and five is a clap of thunder. "When I multiply numbers together, I see two shapes. The image starts to change and evolve, and a third shape emerges. That's the answer." (Fantastic Story and Interview in the Guardian)

New findings featured on the British Web site, Nature Chemical Biology, indicate a way to block the aging of cells. Prof. Kim Tae-kook at the Korea Advanced Institute of Science and Technology explained:
``All cells face an inevitable death as they age. On this path, cells became lethargic and in the end stop dividing but we witnessed that (our) synthetic compound,CGK733, can block the process. . . We also found it can reverse aging, by revitalizing already-lethargic cells. Theoretically, this can give youth to the elderly via rejuvenating cells.’’ the 41-year-old said. (Korea Times )

Teenagers today are drinking less, smoking less and having less sex than their peers did 15 years ago, according to a national study released Thursday by the federal Centers for Disease Control and Prevention.
High school students who had smoked one cigarette in their lifetime dropped to 54 percent, compared with 70 percent in 1991. The number of teens who had at least one alcoholic drink dropped from 81 percent in 1991 to 74 percent last year.
And during the same period, students reporting at least one sexual experience declined from 54 percent to 47 percent. (LA Times) |

The Food and Drug Administration today approved the first vaccine that protects against the viruses known to cause 70 percent of cervical cancers. In a two-year study of more than 12,000 women, Gardasil was shown to be highly effective as an immunization for girls and women ages nine to 26.
The vaccine was found to be 100 percent effective against four types of human papillomavirus that are responsible for about 70 percent of cervical cancer cases, and others that cause 90 percent of genital wart cases. (HealthDay)
