Stunning discovery: First evidence of a self-healing metal

Posted by in categories: engineering, nanotechnology, transportation

A team of scientists from Sandia National Laboratories and Texas A&M University has recently witnessed for the first time a stunning phenomenon: pieces of metal cracking, then fusing back together without any human intervention.

If this amazing phenomenon can be harnessed, it could give rise to an engineering revolution in which self-healing bridges, engines, or airplanes could reverse damage caused by wear and tear and thus become safer and longer-lasting.

“This was absolutely stunning to watch first-hand,” said Brad Boyce, a materials scientist at Sandia. “What we have confirmed is that metals have their own intrinsic, natural ability to heal themselves, at least in the case of fatigue damage at the nanoscale.”

Is emergence a mystery? Does ordinary stuff have mysterious properties? Take anything; find and separate all its parts and catalogue their properties. Then recombine those parts. What would you get? Nothing at all like what you expect from the sum of all those properties. It’s called ’emergence’ and it describes how wondrously our world works on every level.

US scientists discover chemical to reverse aging

Posted by in categories: biotech/medical, chemistry, life extension

In a groundbreaking study, researchers have unlocked a new frontier in the fight against aging and age-related diseases. The study, conducted by a team of scientists at Harvard Medical School, has published the first chemical approach to reprogram cells to a younger state. Previously, this was only achievable using a powerful gene therapy.

The team’s findings build upon the discovery that the expression of specific genes, called Yamanaka factors, could convert adult cells into induced pluripotent stem cells (iPSCs). This Nobel Prize-winning discovery raised the question of whether it might be possible to reverse cellular aging without causing cells to become too young and turn cancerous.

SRF experiment.com campaign sets sights on mitochondrial DNA

Posted by in categories: biotech/medical, life extension

Following the success of its first experiment.com campaign, which was raising money to identify therapeutics that reduce senescent cell accumulation and extend healthspan, the SENS Research Foundation has announced the next funding project.

Last month, we covered the fundraiser for Dr Abdelhadi Rebbaa’s research into the discovery and testing of novel senolytic molecules, which would back into his discovery of potential anti-senescence therapeutics. SRF has confirmed that this campaign is now fully funded.

Now SENS Research Foundation has launched its second experiment.com campaign for Dr Amutha Boominathan’s project Finding a cure for mitochondrial DNA diseases through COX2 variations to restore cell function, hoping to raise $8,000 over 45 days, with the campaign coming to an end next month, on 30th August. Dr Boominathan is head of the MitoSENS program at SENS Research Foundation.

Researchers uncover potential biomarkers of positive response to immunotherapy

Posted by in category: biotech/medical

Scientists at the UCLA Jonsson Comprehensive Cancer Center have identified potential new biomarkers that could indicate how someone diagnosed with metastatic melanoma will respond to immunotherapy treatment.

The researchers found when T cells are activated, they release a protein called CXCL13, which helps attract more B cells and T cells to the tumor site. The B cells then show the T cells specific parts of the tumor, which leads to increased activation of the T cells and their ability to fight the cancer. This cooperation between T cells and B cells was associated with improved survival in patients diagnosed with who were treated with immunotherapy, but not for those who received targeted therapy (e.g., MEK inhibitors).

These findings could help guide new strategies to improve the effectiveness of melanoma cancer treatments. The research is published in the journal Frontiers in Immunology.

Regulator says found no animal welfare breaches at Musk firm beyond 2019 incident

Posted by in categories: biotech/medical, Elon Musk, neuroscience

USDA found Neuralink to be in compliance with animal safety and welfare standards after an isolated incident of using an unapproved sealant to close a monkey’s skull in a surgery triggered an investigation. FDA granted a request to begin testing it’s implant device in humans.


July 19 (Reuters) — The head of the U.S. agency responsible for animal welfare has told lawmakers that it did not find any violations of animal research rules at Elon Musk’s Neuralink beyond a 2019 incident the brain implant company had already reported.

Officials with the Department of Agriculture (USDA) conducted a “focused” inspection in response to a complaint about the company’s handling of animal experiments, but identified no compliance breaches, the agency’s secretary Thomas Vilsack wrote to Congressman Earl Blumenauer in a July 14 letter reviewed by Reuters.
