Your Neuralink device would be implanted using traditional neurosurgery methods safely and seamlessly with a robot surgeon. As mentioned in the Neuralink published paper, “We have also built a neurosurgical robot capable of inserting six threads (192 electrodes) per minute. Each thread can be individually inserted into the brain with micron precision for the avoidance of surface vasculature and targeting specific brain regions.”
The Neuralink team has already started experimenting with various versions of the devices on both rats and monkeys. The results have been impressive. During the presentation in San Francisco, Musk and his team described one instance of a monkey being able to control a computer with simply its brain. Unfortunately, (or fortunately) there have not been any tests on humans. Yet, the team hopes to obtain FDA approval and begin human trials as early as this year.
During his presentation Elon Musk reiterated the idea that Neuralink will be an important part of our future, eventually allowing us to reach symbiosis with artificial intelligence. “With a high bandwidth brain-machine interface, we can go along for the ride and effectively have the option of merging with AI”, said Musk. And as for the risks to reach this end goal? Musk reassured his audience that the device will be safe.
You really can not make this up The Bill and Melinda Gates Foundation has donated more than $21 million towards developing a vaccine technology that uses a tattoo-like mechanism which injects invisible nanoparticles under the skin that is now being tested in a vaccine against the virus that causes COVID-19.
Another study funded by the Bill and Melinda Gates Foundation and published in December, 2019 by researchers from the Massachusetts Institute of Technology, the Institute of Chemistry of the Chinese Academy of Sciences in Beijing and the Global Good, Intellectual Ventures Laboratory in Bellevue, WA, describes how “near-infrared quantum dots” can be implanted under the skin along with a vaccine to encode information for “decentralized data storage and bio-sensing.”
“To maximize the utility of this technology for vaccination campaigns, we aimed to create a platform compatible with microneedle-delivered vaccines that could reliably encode data on an individual for at least five years after administration,” said the MIT paper, titled Biocompatible near-infrared quantum dots delivered to the skin by microneedle patches record vaccination. “In addition, this system also needed to be highly biocompatible, deliver a sufficient amount of dye after an application time of 2 min or less, and be detectable using a minimally adapted smartphone.”
Fridrik Laurusson, an author of the microchip study, is from The Global Good, Intellectual Ventures Labarotory . Its website features Microsoft founder Bill Gates on its front page and describes itself as a “collaboration between Bill Gates and Intellectual Ventures” a company founded by Nathan Myhrvold and Edward Jung of Microsoft. Wikipedia describes Intellectual Ventures in Gates’ home state as a private American company that “centers on the development and licensing of intellectual property” and “one of the top-five owners of U.S. patents, as of 2011.

Transplanting insulin-making islet cells comes close to a cure for type 1 diabetes. It was developed in the U.S. and should be available here. But it isn’t.
A nightly jaunt on the exercise wheel enhances muscle-repair capabilities in old mice, according to a new study by researchers at Stanford School of Medicine.
Only older mice saw this benefit, which the researchers found is due to the rejuvenation of the animals’ muscle stem cells.
“The effect in old animals is very significant,” said Thomas Rando, MD, Ph.D., professor of neurology and neurological sciences and director of Stanford’s Glenn Center for the Biology of Aging. “We found that regular exercise restores youthfulness to tissue repair. Their muscle stem cells start to look and behave like those of much younger animals.”
“We were very pleased to find out that even though life span is a very complicated trait caused by variation on a large number of loci, which is true for most complex traits, the number of loci that are in common is a totally finite number. So, we can imagine going on to the next stage and investigating one gene at a time and in combination,” Mackay said.
Scientists believe about 25 percent of the differences in human life span is determined by genetics—with the rest determined by environmental and lifestyle factors. But they don’t yet know all the genes that contribute to a long life.
A study published March 5, 2020, in PLOS Biology quantified variation in life span in the fruit fly genome, providing valuable insights for preserving health in elderly humans—an ever-increasing segment of the population. The paper titled “Context-dependent genetic architecture of Drosophila life span” is the culmination of a decade of research by Clemson University geneticists Trudy Mackay and Robert Anholt.
It remains difficult to address the genetic basis for life span in humans, so researchers conduct their experiments with model systems. Mackay, the Self Family Endowed Chair of Human Genetics, is one of the world’s leading experts on the Drosophila melanogaster model (aka the common fruit fly), which is an excellent model for comparative analysis of human disease and aging. About 70 percent of the fruit fly genome has a human counterpart.

Insulin-producing cells have been restored in mouse models of type 1 diabetes using a new genetic engineering technique.
American scientists adapted the gene editing technology known as CRISPR (clustered, regularly interspaced, short palindromic repeat) to successfully treat mouse models of type 1 diabetes, kidney disease and muscular dystrophy.
CRISPR enables scientists to edit the genetic material of an organism allowing for DNA sequences to be easily altered and gene function to be modified.
Circa 2019
Researchers at Hanyang University, South Korea, have used the gene-editing technology CRISPR-Cas9 to treat obesity and type 2 diabetes in mice, a development that could eventually benefit humans. The therapy specifically reduced fat tissue and reversed obesity-related metabolic disease in the animals.
SEOUL, South Korea (AP) — A barrage of North Korean missiles fired from both the ground and fighter jets splashed down on the waters off the country’s east coast on Tuesday, South Korea’s military said, a show of force on the eve of a key state anniversary in the North and parliamentary elections in the rival South.
The back-to-back launches were the latest in a series of weapons tests that North Korea has conducted in recent weeks amid stalled nuclear talks and outside worries about a possible coronavirus outbreak in the country.
North Korean troops based in the eastern coastal city of Munchon first launched several projectiles — presumed to be cruise missiles — on Tuesday morning, South Korea’s Joint Chiefs of Staff said in a statement.
