Scientists find aging gene is linked to immunity

LONDON (Reuters) – British scientists studying the genetics of aging said on Thursday that experiments on laboratory worms showed that a specific gene is strongly linked to lifespan, immunity and disease resistance.

Since the gene, called DAF-16 in worms, is found in many animals and in humans, the finding could open up new ways to affect aging, immunity and resistance in humans, the scientists said.

"We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity," said Robin May of the University of Birmingham, who led the study.

Populations across the world are aging at a staggering pace, posing potentially big challenges for health and social care systems. A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays.

Scientists are keen to find out how people age to try to develop drugs to help them stay healthier as their lives extend.

"What we have found is that things like resistance and aging tend to go hand in hand," May said in an interview.

With BO care we won’t have any elderly, so this money can be saved.

Inquiring minds need to know.

How did they know when they had an OLD WORM, is all I would like for them to tell me, ROFL. They are the scientist after all, explain.

Well what do you know.... I may not be a geneticist, and I haven't stayed in a Holiday Inn Express in quite a while, but that just makes way too much sense to me. So much so, it seems like a no brainer to me.

Usually, because they have raised them from "birth". Or, in the case of higher species (lab rats, hamsters, etc), bought them from companies that specialize in raising such critters.

Speaking of staggering, it is no comfort to me that you are the fourth oldest FReeper still posing on this forum. I have never eaten worms but I used to lick my fingers after baiting the hook so maybe...

After the first fifth, with a little lime and salt, the worms are a delicacy... um, I hear.

I think my grandmother told me this about 40-50 years ago, "time moves faster as you get older so don't be so impatient with things now".

Idiots.

I drive 30 mph in the fast lane so I guess I got your grandmother’s message and didn’t know it

I guess I’d best turn in the mountain bike for a walker, just in the event the pace accelerates further. I’m way too young to retire, but ya never know... if things keep speeding up, I might have to draw what’s left of social security by the end of spring. Damn, I’m feeling older every minute now. I don’t know how long I can keep typing, what with the rheumatism and such. I’d hoped I could have gotten the kid past junior high.

Sigh.

Guess I’ll go eat worms.

I’m still trying to recover from racing with grandsons Saturday. Must have gone too fast there and burned up several months.

The only “fast lane” Tork has in his burg is Fourth and Fifth Streets, and the speed limit is 30. I know what he’s got hidden in his barn though. If he got a wild hare, he could really rip it up. Pictures at ten...

Don’t know if it was so much the speeds as it was grandson acting like he was at Bristol.

The boy’s watched too much short track racing!

My grandson hit me up yesterday for a donation to a fund to finance his purchase of a TIG welder. He told me it was cheaper then posting bail and hiring a defense attorney for him.
