Poorer children nearly three times as likely to be obese, new study finds

Posted: 11 Dec 2015 10:06 AM PST

A new study has questioned why poorer children are at higher risk of obesity compared to their better-off peers. The link between relative poverty and childhood obesity turned out to be quite stark. At age 5, poor children were almost twice as likely to be obese compared with their better off peers. 6.6% of children from families in the poorest fifth of the sample were obese while the figure for the richest fifth is just 3.5%. By the age of 11 the gap has widened, nearly tripling to 7.9% of the poorest fifth are obese; for the best-off, the figure is 2.9%.

Active ingredient in magic mushrooms reduces anxiety, depression in cancer patients

Posted: 10 Dec 2015 03:16 PM PST

Psilocybin, found in magic mushrooms, decreased anxiety and depression in patients diagnosed with life-threatening cancer.

The positive effects lasted 6 months.

LSD alters consciousness, but the mechanism of how this happens has been elusive. Now researchers report that LSD interferes with the patterns of activation in brain networks that underlie human thought and behavior. The investigators used functional MRI scans and magnetoencephalography, and showed that LSD reduces connectivity within brain networks and reduces the extent to which separate networks remain distinct in their patterns of firing.
