"Why can’t you exercise self-control?” That disdainful question has been posed repeatedly to procrastinators, overeaters and others who find it hard to resist self-destructive impulses. It has rarely, if ever, been asked of dogs. But according to newly published research, the same mechanism that regulates human self-control also operates in canines. The study, in the journal Psychological Science, confirms the notion that self-control is a limited resource, one that can and does get depleted. It also suggests this is not “a uniquely human process.” A University of Kentucky ... Read More

This bit of research should make you smile (or maybe smirk). Ernest L. Abel and Michael L. Kruger at Wayne State University have found that the larger your smile, the longer you may live.

The professional ball players were chosen as a ... Read More

For years it's been a classic chicken-or-egg riddle: Does smoking marijuana lead to schizophrenia, or are those with schizophrenia who use cannabis simply seeking the calming effects of the drug? Researchers have suspected a link since the 1960s, and study after study has hinted that use of marijuana may trigger schizophrenia, a serious mental illness that affects one in 100 people. Recent studies, however, provide evidence strong enough to give public health officials — not to mention parents and educators — pause, especially as legalization efforts pick up steam. The latest to ... Read More
