Blame game: Sleepier college students are more likely to blame others and plan revenge (July 7, 2011) -- Sleepier people are more likely to imagine how outcomes could have been better than reality and think about how the behavior of others could have produced better outcomes, a new study finds. In contrast, sleepier people were not more likely to imagine how their own behavior could have produced better outcomes. Sleepiness also was positively correlated with all three subscales of displaced aggression: angry rumination, behavioral displaced aggression and revenge planning. The study involved 108 college students. ... > full story
Unexpected cell repairs the injured spinal cord (July 7, 2011) -- A new study has revealed how scar tissue is formed after damage to the central nervous system.

Diabetes drug side effects traced to fat action (July 7, 2011) -- For better or worse, a popular class of anti-diabetic drugs does more than lower blood sugar. One known as rosiglitazone (trade name Avandia) has been in the spotlight for its possible link to increased cardiovascular events, but it also seems to come with unexplained vascular benefits and an unwelcome tendency for weight gain. Now, two separate studies explore those other effects of the drugs known collectively as thiazolidinediones (TZDs), both of which stem from their activity in fat. ... > full story
