Expert Disaster Preppers Explain How to Ride Out the Coronavirus Pandemic

Posted by in categories: biotech/medical, food

For guidance in this time of uncertainty, we spoke with five expert preppers about what they’re doing to ride out the pandemic, how they’ll be ready for whatever comes next—and how you can be too.


Long lines outside grocery stores. Aisles stripped of canned food, toilet paper, and hand sanitizer. A fast-moving pandemic disease that, as of last week, was infecting more than 30,000 people every day.

Just a month ago, such a situation was unimaginable for most of us. But for disaster preppers, it’s precisely the scenario they’re determined to be ready for.

Gene editing rids mice of DNA segment linked to autism

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

Researchers have used the gene-editing technique CRISPR to delete a segment of DNA associated with autism and schizophrenia from mouse brain cells.

The technique has only proven effective in mice so far but may eventually be suitable for treating brain conditions in people, says Xiao-hong Lu, assistant professor of pharmacology and neuroscience at Louisiana State University Health in Shreveport.

Unlike techniques used to manipulate DNA in the mouse brain, CRISPR can be applied to people. He says, “We need a tool to help us to carry the genetic elements into the [human] brain.”

Study points to evidence of stray dogs as possible origin of SARS-CoV-2 pandemic

Posted by in category: biotech/medical

Ever since the outbreak of the SARS-CoV-2, scientists have been scrambling to identify the species of origin to understand how the new coronavirus first leapt from its animal hosts to humans, causing the current pandemic infecting more than a million people worldwide.

Scientists have been looking for an intermediate animal host between bats, which are known to harbor many coronaviruses, and the first introduction of SARS-CoV-2 into humans.

Many animals, beginning with snakes and most recently, pangolins, have all been put forth as the likely intermediate, but the viruses isolated from them are too divergent from SARS-CoV-2, suggesting a common ancestor too far back in time—-living in the 1960s.

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.”

Bill Gates and Intellectual Ventures Funds Microchip Implant Vaccine Technology

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.”

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.
