Bill Gates and Intellectual Ventures Funds Microchip Implant Vaccine Technology

Posted by in categories: biotech/medical, computing, mobile phones, nanotechnology, quantum physics

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.”

O,.o 2019


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.

Exercise restores youthful properties to muscle stem cells of old mice

Posted by in categories: biotech/medical, life extension

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 saw this benefit, which the researchers found is due to the rejuvenation of the .

“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 restores youthfulness to tissue repair. Their muscle stem start to look and behave like those of much younger animals.”

Geneticists zeroing in on genes affecting life span

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

“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.

CRISPR has success in treating mice with type 1 diabetes

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

Circa 2017


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-Cas9 successfully reverses type 2 diabetes in mice

Posted by in categories: biotech/medical, genetics

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.

North Korea fires barrage of missiles from ground and air

Posted by in categories: biotech/medical, existential risks, military

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.

Humming greatly increases nasal nitric oxide

Posted by in category: biotech/medical

The paranasal sinuses are major producers of nitric oxide (NO). We hypothesized that oscillating airflow produced by humming would enhance sinus ventilation and thereby increase nasal NO levels. Ten healthy subjects took part in the study. Nasal NO was measured with a chemiluminescence technique during humming and quiet single-breath exhalations at a fixed flow rate. NO increased 15-fold during humming compared with quiet exhalation. In a two-compartment model of the nose and sinus, oscillating airflow caused a dramatic increase in gas exchange between the cavities. Obstruction of the sinus ostium is a central event in the pathogenesis of sinusitis. Nasal NO measurements during humming may be a useful noninvasive test of sinus NO production and ostial patency. In addition, any therapeutic effects of the improved sinus ventilation caused by humming should be investigated.

NanoViricides, Inc. Progress on COVID-19 Drug Encouraging

Posted by in categories: biotech/medical, nanotechnology

The company’s update on its development of COVID-19 drug candidate is promising.

Vancouver, British Columbia—(Newsfile Corp. — March 31, 2020) — NanoViricides, Inc. (NYSE American: NNVC) (the “Company”) is a nano-biopharmaceutical Company at the development stage, with proprietary and patented drug development work focused on viral diseases. The Company’s research involves the use of a unique nanomedicine technology called nanoviricides — agents designed to “fool” a virus into attaching to an antiviral nanomachine, in the same way that the virus normally attaches to the receptors on a cell surface, but for the purpose of its neutralization and destruction. NanoViricides was highlighted by SmallCapsDaily for providing an update on its progress to develop a drug that can treat COVID-19, the coronaviral pneumonia disease which is caused by the SARS-CoV-2 virus, aka, 2019-nCoV, also known as the Wuhan coronavirus.
