A dog collar that tracks when something is wrong with their humans

Changes in a dog’s behavior could clue us into problems in their owners’ lives.

Lassie’s barking may have saved many humans from a barn or forest fire, but Newcastle University researchers in England say that even more subtle changes in a dog’s behavior could clue us into problems in their owners’ lives–especially if those owners are older, isolated, and might eschew Fitbits and other wearable tracking devices themselves.

New drug cures mice of Down Syndrome in a single dose

With one dose, the brains of the mice grew normally and those mice showed learning abilities like that of their un-affected peers.

There has been good news in medicine recently. Not only is there a vaccine to prevent HIV/AIDS in the works, but scientists at John Hopkins University and the National Institutes of Health have also recently used a new drug to cure Down Syndrome in baby mice with just one dose. And although the drug has not yet been tested on humans, it still qualifies as an amazing achievement.

Change to a single gene increases mouse lifespan 20%

Scientists also discovered individual organ and body parts reacted differently to the process in the engineered mice.

Most Americans aren’t entirely fond of the idea of immortality as shown by recent studies. But it’s probably a good bet that they still wouldn’t mind extending their lifespans by 10-15 years. If researchers at the National Heart, Lung and Blood Institute (NHLBI) have their way, that wish could become a reality. These scientists have successfully extended the lives of mice by changing a single gene.
