Extreme floods are slashing global rice yields faster than expected

Intense flooding has significantly reduced rice harvests around the world in recent decades, putting at risk the food supply of billions of people who rely on the grain as a dietary staple. Between 1980 and 2015, annual losses averaged about 4.3%, or roughly 18 million tons of rice each year,…

Smoking cannabis with tobacco may disrupt the brain’s “bliss molecule”

People who use both cannabis and tobacco show measurable differences in brain activity compared to those who rely solely on cannabis, according to new findings from a McGill University team at the Douglas Research Centre. These results may help clarify why people who combine the two substances more often experience…
