Scientists Find the Real Fountain of Youth — Inside Our DNA
Researchers experiment with gene deletion.
We have a finite time on this Earth and we all want to make the most of it. However, sometimes the side effects of aging get in the way. Technology is helping in a big way to make aging a more graceful process, but some scientists are seeking something greater: the fountain of youth. Rather than looking for it in some ancient jungle, researchers are trying to find the key within our genome to “edit out” the bad stuff.
Longevity, living longer and maintaining independence has been always been on the minds of scientists. A new study published in the journal Cell Metabolism may have found a key to increasing the lifespan of humans.
Entrepreneur Peter H. Diamandis discusses his work with Human Longevity Inc., which seeks to extend the healthy human lifespan.
“This study looks at aging in the context of the whole genome and gives us a more complete picture of what aging is,” explained lead author Brian Kennedy in an interview with The Telegraph.
"Almost half of the genes we found that affect aging are conserved in mammals. In theory, any of these factors could be therapeutic targets to extend health span. What we have to do now is figure out which ones are amenable to targeting.”
The researchers used yeast, deleting a single gene among 4,698 strains and then waiting to see which one outlasted the others.
They found deleting a gene called LOS1 helped extend the lifespan of a strain of yeast by 60 percent. This gene is associated with calorie restriction, and a low-calorie diet has been shown to delay or offset certain aspects of aging.
The find is an interesting one, but there are still many secrets yet to unlock when it comes to understanding why and how we age.

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.
Carl Sagan liked to smoke weed. His essay on why is fascinating.
- Carl Sagan was a life long marijuana user and closeted advocate of legalization.
- He once wrote an anonymous essay on the effects it had on his life and why he felt it should be legalized.
- His insights will be vital as many societies begin to legalize marijuana.
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
