Boosting body’s antiviral immune response may eliminate senescent cells

Posted by in categories: biotech/medical, life extension

Senescent cells are those that have stopped dividing but haven’t read the “time to die” memo. Instead, they hang around, accumulating in the body and fueling chronic inflammation – sometimes called inflammaging – which in turn, contributes to conditions such cardiovascular diseases, chronic kidney disease, type 2 diabetes, cancer, sarcopenia and degenerative disorders.

Longevity. Technology: In mice, eliminating senescent cells from aging tissues can restore tissue balance and lead to an increased healthy lifespan. Now a team led by investigators at Massachusetts General Hospital (MGH), a founding member of Mass General Brigham (MGB), has found that the immune response to a virus that is ubiquitously present in human tissues can detect and eliminate senescent cells in the skin [1].

For the study, which is published in Cell, the scientists analyzed young and old human skin samples to learn more about the clearance of senescent cells in human tissue.

Lightning Bolt Deposits a Strange Mineral Never Seen on Earth Before

Posted by in categories: climatology, space

A lightning bolt that struck a tree on Florida’s west coast has produced a fascinating type of phosphorus material we haven’t seen on Earth before: one that could represent a whole new mineral group, bridging the gap between space minerals and minerals found on Earth.

The material, which is a close match for calcium phosphite (CaHPO3), was found trapped inside a fulgurite – a “metal glob” formed by the reaction of the ultra-hot lightning bolt with the sand around the roots of its target.

These ‘fossilized lightning’ fulgurites often occur when lightning strikes certain types of sand, silica, and rock. What’s much less common is to find something so unique hidden inside one of these structures.

MIT Researchers Make Discovery That Could Lead To The Reversal Of Alzheimer’s Disease

Posted by in categories: biotech/medical, neuroscience

Neuroscientists at MIT have discovered a way to potentially reverse neurodegeneration and other issues related to Alzheimer’s disease, according to a news release from the school.

Researchers, experimenting on mice, found that interfering with an enzyme that is typically overactive in the brains of people with Alzheimer’s can reverse the degeneration in the brain.

Web2’s Lesson for AI: Decentralize to Protect Humanity

Posted by in categories: blockchains, governance, robotics/AI

In order to prevent the potentially destructive impact of AI on humanity, we need open-source innovation and collective governance that is possible through blockchain protocols and Web3, rather than the monopoly defaulting structure of Web2, according to Michael Casey, CoinDesk’s chief content officer.

Explaining the Singularity

Posted by in categories: bioengineering, biological, nanotechnology, quantum physics, robotics/AI, singularity

The Singularity is a technological event horizon beyond which we cannot see – a moment in future history when exponential progress makes the impossible possible. This video discusses the concept of the Singularity, related technologies including AI, synthetic biology, cybernetics and quantum computing, and their potential implications.
