Renegade immune cells found to raid aging brains and choke new neuron generation

Rich Haridy July 3, 2019

A study has revealed killer immune cells have been found to collect in parts of the brain where new nerve cells are generated. This proliferation seems to naturally increase as a brain ages and the researchers hypothesize this may be a mechanism that underpins general age-related cognitive decline.

Researchers hypothesize a newly discovered mechanism may be responsible for general age-related memory problems

Anti-aging compound from pomegranates proves promising in human clinical trials

Michael Irving June 16, 2019

Researchers at EPFL have now reported a new step towards anti-aging medication. Human clinical trials of a fruit-derived compound showed promise in slowing mitochondrial aging in elderly patients, with no side effects found.

A compound derived from pomegranates appears to be effective at slowing some cellular aging processes in ...

Protein from the blood of young mice found to extend lifespan of older mice

Rich Haridy June 16, 2019

A new study is offering a new hypothesis to explain the long-standing idea that transfusions of young blood can reverse the effects of aging. The study reveals when older mice are supplemented with a protein taken from the blood of young mice, they live longer and exhibit youthful characteristics.

The lifespan of older mice was extended when a protein called eNAMPT was isolated from the ...

Gut microbiome restoration rejuvenates aging immune system in mice

Rich Haridy June 4, 2019

A new study suggests age-related immune system decline is not irreversible, and can possibly be improved by replenishing an aging gut microbiome. The scientists discovered fecal transplants from young mice to old mice resulted in significant improvements to the animal’s gut immune system.

The above image shows immune cells in the epithelial lining of the intestine of a young ...

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 ...

Space experiment looks to slow the aging process using nanoparticles

David Szondy May 6, 2019

The latest SpaceX Dragon cargo mission to the International Space Station (ISS) included an experiment that could help to combat aging here on Earth, as well as chronic illness and space-related stresses for astronauts on prolonged space missions.

The Kubik incubator on the ISS will be used to conduct experiments searching for a longer-lasting ...

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 ...

Geneticists use CRISPR to cut toxic protein out of the aging equation

Nick Lavars February 20, 2019

A team of genetic scientists at the Salk Institute have developed a new therapy using the CRISPR/Cas9 tool that takes a toxic protein out of the aging equation, with some promising results.

A new technology developed at the Salk Institute has revealed a new pathway in the development ...
