Circa 2017 Bats harbor a large diversity of coronaviruses (CoVs), several of which are related to zoonotic pathogens that cause severe disease in humans. Our screening of bat samples collected in Kenya from 2007 to 2010 not only detected RNA from several novel CoVs but, more significantly, identified sequences that were closely related to human CoVs NL63 and 229E, suggesting that these two human viruses originate from bats. We also demonstrated that human CoV NL63 is a recombinant between NL63-like viruses circulating in Triaenops bats and 229E-like viruses circulating in Hipposideros bats, with the breakpoint located near 5′ and 3′ ends of the spike (S) protein gene. In addition, two further interspecies recombination events involving the S gene were identified, suggesting that this region may represent a recombination “hot spot” in CoV genomes. Finally, using a combination of phylogenetic and distance-based approaches, we showed that the genetic diversity of bat CoVs is primarily structured by host species and subsequently by geographic distances.

If you are interested in superlongevity, then I have something that you must read. I have previously recommended a book by Dr. David Sinclair called Lifespan. Here I am recommending a research paper that discusses one of the critical experiments in epigenetic age reversal. Normally I would read a paper first before recommending it. However, I think this is a blockbuster, and it’s over 50 pages, so I can’t wait till my slow eyes finish before passing this on. Here is an excerpt:
Age reversal!

Scientists studied 17,308 human brains from the UK Biobank to see how alcohol affects brains. The brain ages one week per drinking session.
Surprising findings could springboard the development of new anticancer drugs, or potentially even directly repurpose existing drugs for cancer therapy.
Drugs that are currently used to treat a wide range of conditions such as diabetes, inflammation, alcoholism, and even canine arthritis, can also kill laboratory-grown cancer cells, according to the results of a study by scientists at the Broad Institute of MIT and Harvard and Dana-Farber Cancer Institute. Using a molecular barcoding technology called PRISM (profiling relative inhibition simultaneously in mixtures) the researchers were able to screen thousands of existing drug compounds against different types of cancer cell lines. The results identified 49 compounds with previously unrecognized anticancer activity. The researchers say their surprising findings, which highlighted novel anticancer mechanisms and targets, could feasibly be used to springboard the development of new anticancer drugs, or potentially even directly repurpose existing drugs for cancer therapy.

A hungry nanoparticle that enters your body and eats away at your insides sounds like a nightmare straight out of a Michael Crichton novel. In fact, it could be a future defense against heart attacks, strokes, and potentially other fatal diseases — as strange as that might initially sound.
Developed by scientists at Michigan State and Stanford universities, the innovative new “Trojan Horse” nanoparticle works by munching away portions of the plaques responsible for heart attacks. In a proof-of-concept demonstration, the researchers recently showed that their specially developed nanoparticle is able to accurately home in on atherosclerotic plaque, which is responsible for atherosclerosis, one of the leading causes of death in the United States.
“What the nanotherapy does is it enters inflammatory monocytes [a type of white blood cell] in the blood, and carries them into the plaque — hence the ‘Trojan Horse’ label — where they become macrophages, and stimulatesthose and other macrophages in plaque to devour cellular debris,” Bryan Smith, associate professor of biomedical engineering at MSU, told Digital Trends. “This ‘taking out the trash’ attribute stabilizes the plaque with minimal side effects.”
Scientists are posting their papers on the China outbreak as fast as they can write them, skipping traditional journals.
New gut bacteria research reveals that gut microbes can differ depending upon what region of the world you live in.
I know it is cute to talk about. But the so deemed Longevity secret of this article being amazingly similar to all other studies (again olive oil and wine) then they go on to declare the ages of the village and they then say some of them have even lived past one hundred??? There are many centenarians (I prefer to call them centurians) in all nations that fly under the radar. Such as in Dallas several times a week they wish some one on channel 4 news that is 100 or greater Happy Birthday. But I believe this is a false alarm looking for a place to go off-sound… You be the Judge??? AEWR.
