The muscle-building dietary supplement creatine helps women battling depressions, according to a study from South Korea and the University of Utah. It reports that women with major depressive disorder (MDD) who augmented their daily antidepressant with 5 grams of creatine responded twice as fast and experienced remission of the illness at twice the rate of women who took the antidepressant alone.

Sharpless 2-292, a stellar nursery called the Seagull Nebula because it seems to form the head of the seagull, glows brightly due to the energetic radiation from a very hot young star lurking at its heart. Now it has gotten a new look courtesy of the Wide Field Imager on the MPG/ESO 2.2-meter telescope at La Silla Observatory.
Active video gaming using dancing and boxing were associated with increased heart rate, oxygen uptake and energy expenditure in a study of 18 school children in England, according to a report in Archives of Pediatrics&Adolescent Medicine.

It sure beats rest and sedentary video game play, anyway.

Low levels of physical activity have been linked to obesity. Active video game playing compared with traditional sedentary video game playing encourages more movement and could help children increase their physical activity levels, according to the study background.
New research may offer some hope to women whose fertility has been compromised by the side-effects of cancer therapy or by premature menopause.

In a new study, researchers from Monash University and Prince Henry's Institute of Medical Research found that two proteins, PUMA and NOXA, cause the death of egg cells in the ovaries.

Blocking the activity of the proteins may lead to new strategies to protect women's fertility.

They focused their studies on primordial follicle oocytes,
egg cells which provide each woman's lifetime supply of eggs. Low numbers of these egg cells can also cause early menopause. 
Dentistry has been around for almost long as people have had teeth go bad but evidence for dentistry is another matter entirely. We don't pull off an arm when it is sore so the first human to figure out that pulling something attached to the skull would help keep people alive was taking nearly as big a chance as the first patient.

Ancient evidence of prehistoric dentistry has been discovered in a Neolithic graveyard in Pakistan and other findings in a Neolithic graveyard near Parma have detailed creative tooth work. An artificial tooth from the cemetery of Gebel Ramlah, Egypt, dates back 5,500 years.
Combat traits usually get most of the attention from researchers, because they are thought to have arisen due to intense male-male competition for access to females. Large, elaborate weapons become the focus of sexual selection studies because the connection is obvious. Collared lizards (Crotaphytus collaris), for example, have bite force correlated with head width, and it positively predicts the number of offspring produced in a breeding season, suggesting sexual selection on head morphology and the role of attacking traits.
