Studies say . . . a memory boost and the shock of birth

Chocolate makes snails smarter and fish could start losing weight


 

British Columbia: Researchers at the University of British Columbia have found that changes in ocean and climate systems could result in smaller fish. The study, published in the journal Nature Climate Change, looked at more than 600 species of fish from oceans around the world. It determined the maximum body weight the fish can reach could decline by 14 to 20 per cent by the year 2050.

Alberta: University of Calgary researchers exposed snails to epicatechin, a component found in many foods, including chocolate and green tea. In the study, published in the Journal of Experimental Biology, they found it helped boost the molluscs’ memories. They couldn’t determine yet whether the findings apply to humans.

Manitoba: Findings from the University of Manitoba’s faculty of medicine show that children from lower-income areas have a tougher time than kids from higher-income areas in health and school. Most worrisome, the study, which tracked Manitoba children aged 19 and under from 2000 to 2010, found that the rate of child deaths in lower-income areas was more than three times greater than in higher income areas.

Ontario: With flu season creeping up, a new study by Public Health Ontario suggests that ethnic communities are more likely to get a flu shot than Canadians who identify themselves as white or black. A dozen ethnic groups, including Filipino, Japanese, southeast Asian and Chinese, were all found to be more likely to get the shot.

Quebec: For a minority of mothers, giving birth leads to the same psychological shocks felt by soldiers in war. Researchers at McGill University found one in 13 mothers suffers post-traumatic stress disorder following delivery. The women suffer flashbacks, nightmares, sleeplessness and try to avoid anyone who reminds them of the trauma of birth, including their babies.

  1. And just how do you test a molluscs’ memory?
