Future anti-aging drugs could flip a “metabolic switch” to mimic fasting

Posted by in categories: biotech/medical, life extension

Fasting has been found to have a range of health benefits, and appears to slow down the aging process. Now, researchers from MIT have found that fasting for just 24 hours is enough to improve the regeneration of a person’s intestinal stem cells, which naturally declines with age. Better yet, with the metabolic switch identified, in the future the effect could be mimicked with a drug.

As with stem cells in all parts of the body, intestinal stem cells are in charge of growing new cells in the organ. They maintain the lining of the intestine, which is shed and replaced every few days, fight off infection and repair damage to the tissue. But as is usually the case, these stem cells get less and less effective at their job with age.

Previous research has found that caloric restriction, or continual fasting, has a profound effect on health and longevity. These effects have been seen in mice, rats, monkeys, lemurs, and other animals, and although human studies haven’t really been conducted, it seems that we could also benefit from harnessing the diet. So the MIT team set out to study the effects of fasting on intestinal stem cells.

Life Extension Technology in Science Fiction

Posted by in categories: biotech/medical, life extension, robotics/AI

Today we take an amusing look at how science fiction is often portrayed in a jarring way especially when dealing with the topic of life extension.

Those of us who fancy science fiction stories are used to all sorts of technological miracles taking place in them; some are plausible and might become reality at some point in the future, while others are mere fantasies, artistic liberties that are taken to tell a better story and will likely never translate into real-life technologies—or, if they will, they will do so at the cost of rethinking fundamental principles that we’ve thus far considered to be fully established.

In science fiction, we’ve seen faster-than-light travel, teleportation, portals, energy weapons, strong AI, telepathic powers, and radiation-induced superpowers of all kinds; unfortunately, the only “superpower” known to be actually induced by radiation thus far is cancer. Entire imaginary worlds have revolved around the existence of one or more of these marvels, and series and shows have assumed that they’re possible and imagined what our society would be like with them, but one particular possibility has been neglected or relegated to one or two episodes and then forgotten, as if it was of no importance whatsoever: the defeat of aging.

Dr. Sarah Constantin – The Longevity Research Institute

Posted by in categories: biotech/medical, life extension

Today, we have an interview with the Longevity Research Institute, a new group set to launch in April 2018 of this year. The goal of the Institute is to identify therapies that can demonstrably extend healthy human lifespan by 2030 at the latest.

Searching for longevity

There are dozens of compounds and therapies that have been demonstrated to increase the lifespan of mammals. Recently, there have been some impressive examples of rejuvenation in animals using a variety of approaches, including partial cellular reprogramming, stem cell therapy, and senescent cell removal. More importantly, in many of these studies, age-related diseases have been delayed or even reversed.

America’s water infrastructure is failing—but here’s how we could start to fix it

Posted by in categories: climatology, life extension, sustainability

America’s water is under threat from many sides. It faces pollution problems, outdated infrastructure, rising costs, and unprecedented droughts and rainfall patterns as the climate changes. Yet at a recent event hosted by the Columbia Water Center, the tone was cautiously optimistic, and the conversation centered on solutions.

“If we have aging that’s falling apart, and we’re dealing with climate variability and change, isn’t that a good opportunity to actually do something?” suggested Upmanu Lall, director of the Columbia Water Center.

For decades, the U.S. has been a leader in . Now we’re falling behind; in the latest infrastructure report card, dams, drinking water and wastewater all received D ratings. But Lall thinks the country could get an A. Here are some of the solutions, presented at the event, that could help to get us there.

Necroptosis increases with age and is reduced

Posted by in category: life extension

Aging is characterized by the progressive increase in chronic, low‐grade inflammation termed “inflammaging,” which is believed to play an important role in the mechanism underlying aging.


Necroptosis is a newly identified programmed cell death pathway that is highly proinflammatory due to the release of cellular components that promote inflammation. To determine whether necroptosis might play a role in inflammaging, we studied the effect of age and dietary restriction (DR) on necroptosis in the epididymal white adipose tissue (eWAT), a major source of proinflammatory cytokines. Phosphorylated MLKL and RIPK3, markers of necroptosis, were increased 2.7‐ and 1.9‐fold, respectively, in eWAT of old mice compared to adult mice, and DR reduced P‐MLKL and P‐RIPK3 to levels similar to adult mice. An increase in the expression of RIPK1 (1.6‐fold) and MLKL (2.7‐fold), not RIPK3, was also observed in eWAT of old mice, which was reduced by DR in old mice. The increase in necroptosis was paralleled by an increase in 14 inflammatory cytokines, including the pro‐inflammatory cytokines IL‐6 (3.9‐fold), TNF‐α (4.7‐fold), and IL‐1β (5.1‐fold)], and 11 chemokines in old mice. DR attenuated the expression of IL‐6, TNF‐α, and IL‐1β as well as 85% of the other cytokines/chemokines induced with age. In contrast, inguinal WAT (iWAT), which is less inflammatory, did not show any significant increase with age in the levels of P‐MLKL and MLKL or inflammatory cytokines/chemokines. Because the changes in biomarkers of necroptosis in eWAT with age and DR paralleled the changes in the expression of pro‐inflammatory cytokines, our data support the possibility that necroptosis might play a role in increased chronic inflammation observed with age.
