New research suggests eating vegetables gives you a healthy tan. The study showed that eating a healthy diet rich in fruit and vegetables gives you a more healthy golden glow than the sun.-link

Facebook’s facial recognition research project, DeepFace (yes really), is now very nearly as accurate as the human brain. DeepFace can look at two photos, and irrespective of lighting or angle, can say with 97.25% accuracy whether the photos contain the same face. Humans can perform the same task with 97.53% accuracy.-link

A new study finds that the current level of evidence does not support guidelines restricting saturated fatty acid consumption to reduce coronary risk nor does it support high consumption of polyunsaturated fats -- such as omega 3 or omega 6 -- to reduce coronary heart disease.-link

 

The health benefits of eating dark chocolate have been extolled for centuries, but the exact reason has remained a mystery -- until now. Researchers reported that certain bacteria in the stomach gobble the chocolate and ferment it into anti-inflammatory compounds that are good for the heart.-link

CR an artifact?

The most widely accepted theory is that this effect evolved to improve survival during times of famine. "But we think that lifespan extension from dietary restriction is more likely to be a laboratory artefact,"
  says Dr Adler.

Lifespan extension is unlikely to occur in the wild, because dietary restriction compromises the immune system's ability to fight off disease and reduces the muscle strength necessary to flee a predator.-link 

I would also add that since the calorie restriction is done with dense nutrient enriched optimal nutrition, this is unlikely to occur in the wild.  Without optimal nutrition calorie restriction is said to fail to extend life, small amounts of nonenriched foodsource as found in the wild is in my opinion unlikely to provide optimal nutrition required for extension. edit: especially at levels that cr can work in some animals like 60+%, at 60% deprivation not only would the nutrient density likely be insufficient, but in an environment lacking resources the small amount of calories would be insufficient for exploration, cr appears to work and extend life even in calorie amounts beyond what would be sustainable in the wild.

Longevity ted

Last year, Emanuel Saez — an economist from the University of California, Berkeley — made headlines with the finding that 95 percent of income gains from 2009 to 2012 accrued to the top 1 percent of earners. But this finding was not about the rich doing well; their incomes are actually growing a little more slowly than in the last two economic expansions.-link

Comment on fightaging telomerase article

"Contrast that with the SENS hypothesis that aging is molecular and cellular damage that the body cannot repair at any reasonable cost."

If that were the case, we should see SENS like approaches being implemented by nature in negligible Senescence species. If all they've is mostly the same genes and differing expression patterns, then existing mechanisms are sufficient if ramped up. We have over 98% genetic similarity with our closest relative yet over twice the lifespan.

What approach doubled species lifespan?

If we were bonobos with 40year lifespans and we asked SENS proponents. They'd say most of the [easy] longevity changes were already implemented by nature in achieving this lifespan and they'd propose the SENS solutions as a way to lengthen lifespan.

If like me you believed existing mechanisms are mostly sufficient for vast lifespan increase, then you'd suggest mostly gene expression changes with high conservation of the genome. What did nature do? AFAIK, it simply mostly tweaked gene expression and presto triple lifespan.

If you ask me, it is likely that similar tweaks could very likely carry us all the way up to negligible senescence.

 Let's see what we find from the genetic sequences of negligible senescence organisms.

"Indeed; it's not like there aren't plenty of species whose telomeres don't shorten with age, in fact there's a species of bird whose telomeres get -longer- with increasing age, and it ages quite normally."

I've not looked into it deeply, but according to Dr. Bill Andrews, it is only a few species who have significant aging contribution from short telomeres.

"The same thing should happen if you were to repair all the cellular and molecular damage of aging that suppresses stem cell activity."

And it also as mentioned seems to slightly begin to occur with lifestyle changes that increase telomeres.-Darian S in Fightaging
