  • Dog Genes

Researchers have created a genetic map for man's best friend. Now that Tasha, a female boxer, has provided her DNA to be analyzed at institutions all over the world. As a result, scientists have sequenced over two billion letters of her dog DNA, and identified 39 pairs of chromosomes. That is a big deal because researchers say they can use all that information now to help pinpoint the cause of cancer and other diseases in humans. Since biologically, those diseases are similar in dogs and humans.

  • CPR

A joint study by Harvard and Brigham and Women's Hospital suggests many sports related injures are caused by cardiovascular problems after being hit in the chest by a ball, and that using CPR in conjunction with a defibrillator, coaches or even students nearby could have a better chance at saving some of those young athletes. The report cites a 13-year-old boy who went into cardiac arrest, but was revived with CPR and an external defibrillator. Researchers suggest there should be an increase in the use if CPR and better access to defibrillators at sporting events, to protect young athletes.

  • Inflammation

Targeting a special protein in the brain could help reduce chronic pain. Researchers at the University of Toronto say after studying mice that inflammation caused by an injury increases levels of a protein responsible for feeling pain, and they believe that protein level causes the brain to continue to feel pain even after the source of pain is gone. When researchers reduced the protein levels in mice, the level of pain also dropped. The study suggests this finding could someday lead to new treatment for people with chronic pain. This study is published in the Journal of Neuroscience.
