Humans will one day live forever and only die in accidents, claims scientist

It is possible that we can grow biologically younger – and the key is in our blood, according to a scientist.

The biomedical gerontologist – an aging expert – says that one day we won't die from old age or ill health – only as a result of road accidents.

That's according to Briton Aubrey de Grey, who is chief science officer and co-founder of the SENS Research Foundation in Mountain View in California, reports the Daily Mail.

Grey’s company is one of an increasing number of Bay Area researchers pursuing the fountain of youth – focusing on isolating a factor in blood to turn back the hands of time.

The idea is that giving the plasma of the young to the old could help to reverse the effects of ageing.

Researchers at Stanford University, led by neuroscientist Tony Wyss-Coray, showed in a 2014 study that infusions of blood from young mice reversed cognitive and neurological impairments in old rodents.

Now biotech start-ups are racing to replicate this in humans, to achieve what we only know in science-fiction movies: eternal youth and health.

“The risk of death will remain the risk of death from causes other than aging — like being hit by a truck,' Dr de Grey told CBS SF Bay Area.

“We don't know how soon we're going to defeat aging. We should be able to keep people truly in a youthful state of health, no matter how long they live and that means the risk of death will not rise.

“Plasma transfusions are big hot property right now.”

A year after the Stanford research, biotech company Alkahest in San Carlo, California, experimented a step further in a series of trials injecting the blood plasma of 18-year-old humans into old mice.

They found that similar effects to the original study – human blood did rejuvenate both the body and brain, improving cognition and allowing them to frolic about like their younger counterparts.

Knowing that mice are biologically similar to humans, the researchers believed a similar technique could one day be used to benefit us.

The Alkahest team examined the brains of the treated mice, and found that they appeared to have created new cells in the hippocampus.

This process, known as neurogenesis, is thought to contribute to memory and learning, and the results now show that it can be enhanced through the injection of young human blood, New Scientist reports.

According to Sakura Minami, who was involved in the study, some of the factors that give young blood its power have now been identified – but, the team will not reveal them yet.
