Neanderthal-like ‘mini-brains’ created in lab with CRISPR

Posted by in categories: biotech/medical, evolution, neuroscience

“It’s an extraordinary paper with some extraordinary claims,” says Gray Camp, a developmental biologist at the University of Basel in Switzerland, whose lab last year reported2 growing brain organoids that contained a gene common to Neanderthals and humans. The latest work takes the research further by looking at gene variants that humans lost in evolution. But Camp remains sceptical about the implications of the results, and says the work opens more questions that will require investigation.

Humans are more closely related to Neanderthals and Denisovans than to any living primate, and some 40% of the Neanderthal genome can still be found spread throughout living humans. But researchers have limited means to study these ancient species’ brains — soft tissue is not well preserved, and most studies rely on inspecting the size and shape of fossilized skulls. Knowing how the species’ genes differ from humans’ is important because it helps researchers to understand what makes humans unique — especially in our brains.

The researchers, led by Alysson Muotri, a neuroscientist at the University of California, San Diego, used the genome-editing technique CRISPR–Cas9 to introduce the Neanderthal and Denisovan form of a gene called NOVA1 into human pluripotent stem cells, which can develop into any cell type. They cultured these to form organoids, clumps of brain-like tissue, up to 5 millimetres across, alongside normal human brain organoids for comparison.

A magnetic helmet shrunk a deadly tumor in its first test

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

We’ve seen helmets and AI that can spot brain tumors, but a new hard hat can actually treat them, too.

As part of the latest neurological breakthrough, researchers used a helmet that generates a magnetic field to shrink a deadly tumor by a third. The 53-year-old patient who underwent the treatment ultimately died due to an unrelated injury, but an autopsy of his brain showed that the procedure had removed 31% of the tumor mass in a short time. The test marked the first noninvasive therapy for a deadly form of brain cancer known as glioblastoma.

The helmet features three rotating magnets connected to a microprocessor-based electronic controller operated by a rechargeable battery. As part of the therapy, the patient wore the device for five weeks at a clinic and then at home with the help of his wife. The resulting magnetic field therapy created by the helmet was administered for two hours initially and then ramped up to a maximum of six hours per day. During the period, the patient’s tumor mass and volume shrunk by nearly a third, with shrinkage appearing to correlate with the treatment dose.

Longevity Panel II — The Scientists Working of Reversing Aging | Part 1

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

4:47 BioAge, 8:10 Church talking about how controlling aging is no longer speculative, 10:44 urging caution as they are not really talking about turning 67 year olds into 20 year olds. Near the end Church mentions A.I. an exponential possibilities of hitting all the pathways at once.


Recently, Avi Roy, alongside Nathan Cheng & Laura Minquini, hosted the second Longevity Panel discussion, which assembled some of the brightest minds working on reversing aging, and enhancing health and life span.

How Gene Therapy and Algae Proteins Partially Restored a Blind Man’s Sight

Posted by in categories: bioengineering, biotech/medical, genetics, neuroscience

The result is optogenetics, a mind-controlling technique that’s become one of neuroscience’s most popular tools. Here, scientists use genetic engineering to put different types of algae proteins into the brains of mice. They can then activate a neuron with an implanted fiber optic cable by pulsing certain wavelengths of light. These enhanced brain cells react as they would naturally, generating an electrical signal that’s passed down and interpreted by the mouse’s brain.

Sound familiar?

If an algae protein can artificially allow neurons in the brain to translate light into electrical information, why can’t it do the same for damaged eyes?

Aging Teeth and Radical Life Extension

Posted by in categories: biotech/medical, life extension

I know that this is controversial in the longevity community, but there was overwhelming agreement among the dentists I talked with that mouthwash is excellent for preventing gingivitis (one study found that it was more effective than flossing) and reducing plaque.

Gottlieb says U.S. likely “much further in this epidemic than we’re picking up”

Posted by in category: biotech/medical

I believe since the weird localization of the virus in Japan that this sorta self evolving virus needs to have a counter like a self evolving vaccine but at the very least new variants can be made super fast with new technology in vaccine making.


Washington — Dr. Scott Gottlieb, former Food and Drug Administration commissioner, said Sunday he thinks the U.S. is further into the COVID-19 epidemic driven by the Delta variant than Centers for Disease Control and Prevention (CDC) models are picking up. He said that could mean “hopefully we’re going to turn a corner” in the next two to three weeks.

“We’re not doing a lot of testing. More of the testing that we are doing is antigen tests that are being done at home and not getting reported,” Gottlieb said. “So, I think we’re much further into this epidemic than we’re picking up and hopefully further through this epidemic.”

Drones could help save soldiers’ lives by delivering blood on demand

Posted by in categories: biotech/medical, drones, military, robotics/AI

Getting blood to a wounded soldier could be the difference between life and death. A drone swarm is one way to make that happen in battle.


Blood is usually a finite quality on a battlefield. Battles can cause a number of injuries, from the minor to the critical. If a soldier can get the wound closed in time, they can staunch the loss, but keeping the patient alive may require an influx of new blood. As medics work to aid their comrades, they could receive help from an unusual source: delivery drones, bringing literal fresh blood to the battlefield.

A drone swarm capable of delivering blood was part of Autonomous Advance Force 4.0, an exercise by the United Kingdom’s armed forces in which Royal Marines Commandos trained with modern technology for future war. The July exercise took place in Cumbria and Dorset, with a release announced July 17.
