Study shows how diet can prevent a mid-life microbiome crisis and improve brain health

Rich Haridy May 22, 2019

A fascinating new study is suggesting that a shift in gut bacteria in our middle-age could trigger a process that plays a role in cognitive decline in our later years. And diet may be the key to encouraging the growth of beneficial bacteria that benefit healthy brain aging.

An animal study revealed prebiotic dietary interventions in middle-aged mice reduced signs of brain inflammation and ...

Stanford team develops brain-rejuvenating antibodies that let old mice think like youngsters

Loz Blain April 4, 2019

In a stunning piece of research, Stanford neuroscientists have hunted down a single gene that encodes a protein responsible for age-related cognitive losses, targeted it with special blocking antibodies, and shown in mice that these antibodies can rejuvenate old brains to work as well as young ones.

Researchers were able to improve the cognitive function of older mice after blocking a protein's activity ...

Anti-aging study increases worm lifespans by almost 50 percent

Michael Irving March 27, 2019

Given the chance, very few of us wouldn’t want to slow down the aging process. Chasing that fountain of youth is a major branch of medical science at the moment, and now, a team at Scripps Research has found that blocking a particular enzyme can extend the lifespan of worms by almost half again.

Researchers have found a new biological pathway in worms that extends their lifespans by almost half, ...

Cognitive decline prevented in old mice with a dose of young bone marrow

Rich Haridy February 21, 2019

For centuries humans have anecdotally espoused the rejuvenating properties of young blood, however it is only recently that scientists have begun to seriously explore the idea. A new study has homed in on a potential hypothesis revealing young bone marrow transplants improved memory in old mice.

It may not be young blood but in fact young bone marrow that confers cognitive benefits ...

Compelling new link between obesity-related anxiety and “zombie cells” in the brain

Rich Haridy January 6, 2019

A new study has revealed a connection between obesity, anxiety, and the accumulation of "zombie," or senescent, cells in the brain. The research in mice revealed that obesity increases the volume of these cells in the brain, which subsequently increases anxiety-like behavior in the animals.

A mouse study revealed clearing the brain of senescent, or "zombie", cells resulted in the reduction ...
