Researchers design antibodies that destroy old cells, slowing down aging

No one knows why some people age worse than others and develop diseases-such as Alzheimer’s, fibrosis, type 2 diabetes or some types of cancer-associated with this aging process. One explanation for this could be the degree of efficiency of each organism’s response to the damage sustained by its cells during its life, which eventually causes them to age. In relation to this, researchers at the Universitat Oberta de Catalunya (UOC) and the University of Leicester (United Kingdom) have developed a new method to remove old cells from tissues, thus slowing down the aging process.

Specifically, they have designed an antibody that acts as a smart bomb able to recognize specific proteins on the surface of these aged or senescent . It then attaches itself to them and releases a drug that removes them without affecting the rest, thus minimizing any potential side effects.

The results of this work, which have been published in Scientific Reports, open the door to the development of effective treatments to delay the progress of age-related diseases and even the aging process itself in the longer term, with the aim of increasing the longevity and, above all, the quality of life of people at this stage of their lives.

HEALTH EXPERT Reveals The Secret To AGING IN REVERSE | David Sinclair

I’m confused. At 34:20 he says he says people in clinical trials had there age reversed 2 years (I assume he is talking about thymus rejuvenation) and it is additive so people who had it 4 times went back 8 years. Ok. AND?! I mean am I missing something here? Is this not what we are after? I’m 50 now, so if I did it 13 times will I be 24 again?

My guest today is a revolutionary thinker and ground-breaking scientist who’s on a mission to make you younger. He’s Australian biologist and Harvard professor David Sinclair, author of Lifespan: Why We Age – And Why We Don’t Have To. David is one of the world’s leading scientific authorities on longevity, ageing and how to slow its effects.

Aided by stem cells, a lizard regenerates a perfect tail for the first time in 250 million years

Lizards can regrow severed tails, making them the closest relative to humans that can regenerate a lost appendage. But in lieu of the original tail that includes a spinal column and nerves, the replacement structure is an imperfect cartilage tube. Now, for the first time, a USC-led study in Nature Communications describes how stem cells can help lizards regenerate better tails.

“This is one of the only cases where the regeneration of an appendage has been significantly improved through stem cell-based therapy in any reptile, bird or mammal, and it informs efforts to improve wound healing in humans,” said the study’s corresponding author Thomas Lozito, an assistant professor of orthopaedic surgery and stem cell biology and regenerative medicine at the Keck School of Medicine of USC.

Harvard University professor geneticist Dr. George Church stops by the Institute

Talking about RejuvenateBio starts at 20:30. Mentions there are 300 known genes concerning human aging and 45 of those have been tested in mice with what sounds like success.

Wow! Where do I start. I woke up and seen Dr. George Church on Bloomberg news. They was discussing a new biotech startup company called Rejuvenate Bio. A life extension company that seeks to reverse aging in dogs. Then apply that knowledge to humans. I ask Dr. Church about what he thinks is the cause of aging. t. Dr. Church thinks its a genetic reason why we age. Dr. Church is a cofounder of a company called Colossal is a company that wants to create a hybrid between the east asian elephant and the woolly mammoth. The purpose of doing this is to fight climate change and prevent the extinction of the east asian elephant.

IQ2 Debate: Don’t Trust The Promise Of Artificial Intelligence

As technology rapidly progresses, some proponents of artificial intelligence believe that it will help solve complex social challenges and offer immortality via virtual humans.

But AI’s critics are sounding the alarm, going so far as to call its development an “existential threat” to mankind. Is this the stuff of science fiction? Could the “Terminator” become reality, or will these fears prevent the next technological revolution?

Ray Kurzweil — Immortality by 2045

Ray Kurzweil — Singularitarian Immortalist, Director of Engineering at Google, famous inventor, author of How to Create a Mind http://GF2045.com/speakers/.

A world-class prolific inventor and leading futurist author, “the restless genius” (Wall Street Journal) points to 2045 for the technological singularity when A.I. will surpass human intelligence in his New York Times best seller The Singularity is Near, Amazon’s #1 book in science and philosophy.

In this video Ray Kurzweil discusses his predictions about radical life extension, singularity, life expansion and the imminence of physical immortality. He invites participants to the second international Global Future 2045 congress (June 2013) http://www.GF2045.com.

“If we have radical life extension only, we would get profoundly bored, we’d have profound existential ennui, running out of things to do, and new ideas, but that’s not what’s going to happen. In addition to radical life extension, we’re going to have radical life expansion, we’re going to have millions of virtual environments to explore, we’re going to literally expand our brains.”

“We’ll be routinely able to change our bodies very quickly, as well as our environments in virtual reality, but it will feel very real. We’ll ultimately be able to do that with real reality too, like self-organizing swarms of nanobots that can link themselves up into a virtual body.” says Ray Kurzweil.
