Only Humans Experience Age-Related Brain Shrinkage: Study

Age-related brain shrinkage occurs only in humans, researchers say.

By age 80, the average human brain has lost 15 percent of its original weight, BBC News reported.

In this study, scientists compared MRI images from more than 80 healthy humans, ages 22 to 88, and a similar number of captive-bred chimpanzees and found that chimps’ brains don’t shrink with age. The findings appear in the journal Proceedings of the National Academy of Sciences.

The human brain is three times larger than a chimp brain and humans also live longer. The researchers said that longer lifespan is likely an adaptation to having bigger brains, BBC News reported.

Mexican Papayas Linked to Food Poisoning Outbreak

Possibly tainted papayas from Mexico may be the cause of a U.S. food-poisoning outbreak that’s affected more than 90 people in 23 states.

A company in South Texas is recalling papayas imported from Mexico that may be contaminated with salmonella bacteria. The recall covers Blondie, Yaya, Mananita and Tastylicious brand papayas sold before July 23, the Chicago Tribune reported.

Of the 90 reported food-poisoning cases, 17 have occurred in Illinois. Patients had to be hospitalized in eight of the 17 cases, according to the Illinois Department of Public Health.

People who have become ill after eating papayas should seek medical care and contact their local health departments, officials advise, the Tribune reported.
