Iowa State University physicist Kerry Whisnant has developed a mathematical formula that he says predicts how well baseball teams will perform on the field.

The new formula is based on work of Bill James, the baseball author and statistician who inspired sabermetrics, the study of how statistics relate to success on the baseball diamond. James developed a basic formula, which has been tweaked over the years, that uses the number of runs scored per game (RPG) and runs given up per game to estimate a team's winning percentage.
According to a new study in the May issue of the Archives of Pediatrics and Adolescent Medicine, educational DVDs do not improve overall general language learning abilities Among 12- to 24-month old children, and manufacturers' claims that these infant-directed media can teach children specific vocabulary words have not been substantiated.
Researchers from Chungnam National University in Daejeon, South Korea say that increasing dissolved oxygen concentrations in alcohol may reduce drinking-related side effects and accidents. The Results will be published in Alcoholism: Clinical&Experimental Research.

Scientists performed three experiments with 49 healthy volunteers (30 men, 19 women), with a mean age of 27.2 years. Experiment one compared 8 ppm and 20 ppm dissolved oxygen concentrations in 240 ml of 19.5 percent alcoholic beverage. The second compared 8 ppm and 20 ppm dissolved oxygen concentrations in 360 ml of 19.5 percent alcoholic beverage. The final experiment compared 8 ppm and 25 ppm dissolved oxygen concentrations in 360 ml of 19.5 percent alcoholic beverage.
A survey of parents who have lost children to cancer found that one in eight considered hastening their child's death, a consideration influenced by the amount of pain the child experienced during the last month of life, according to a new survey in the Archives of Pediatrics and Adolescent Medicine.

Researchers say the findings underscore the importance of managing patients' pain, and of communicating with parents about the tools available for easing progressive pain.
Teens who spend more time watching television or using computers appear to have poorer relationships with their parents and peers, according to a report in the March issue of the Archives of Pediatrics and Adolescent Medicine.

Given the importance of healthy relationships with friends and family to adolescent development, the researchers suggest that "concern about high levels of screen time among adolescents is warranted" and that more research is needed to monitor the effects of new technologies on the well being of growing teenagers.
Despite research suggesting that sodium reduction would do little to improve public health, scientists writing in the Annals of Internal Medicine say  that a voluntary effort by the U.S. food service industry to reduce salt in processed foods could have far-reaching implications for the health of the U.S. population, preventing strokes and heart attacks in nearly a million Americans and saving $32.1 billion in medical costs.
