A METAPHOR FOR HILLARY AND THE DEMOCRATIC PARTY: Blood from Old Mice Makes Young Mice Decrepit.

Five days later, old mice did see some benefits from having young blood in their veins, including better muscle repair. But Conboy, who reported her findings in Nature Communications, says the really striking finding was just how bad old blood was for the younger animals. The aged blood inhibited the formation of brain cells in young mice and caused the animals to fall behind their peers in a strength test where they are hung upside down on a wire mesh. “The young mice became almost as decrepit as the old ones,” she says.

The research suggests that one day, instead of getting transfusions from young people, aged people will instead go to a medical facility to get their blood cleared of proteins that may build up and promote aging. Conboy says she and other scientists are working to identify what those molecules are.

Faster, please. Plus:

Given the swift and negative effects of old blood on younger mice—the results appeared immediately—this type of research could eventually raise questions about the age of blood-bank donors. A 2008 study in Blood found that the average age of blood donors in the U.S. was 35, but since repeat donors tend to be older, about 35 percent of blood came from people over 50, including many in their 60s.

Hmm.
