Synthetic versions of the deadly virus could help test treatments. But what are the risks when viruses can be synthetized from scratch?
AZOKH, Nagorno-Karabakh (People of Ar)—Scholars from Britain, US, Denmark and Armenia led by Professor Levon Yepiskoposyan have been examining prehistoric caves near the village of Azokh in Artsakh (Nagorno Karabakh) and found unique artifacts from different periods, among them a tooth from a human who lived 7000 years ago. Due to the cave’s climate DNA was preserved inside the tooth and was send to Copenhagen University’s genetics department (in Denmark) for examination. The results of this inquiry have revealed that the genetic makeup of the tooth belonging to an individual 7000 years ago perfectly matches with the genetic makeup of modern Armenians.
“This is the conclusion we’ve reached after numerous excavations carried out on the territory of Karabakh, where we examined more than a dozen caves, among them the cave of Azokh and Alexan Uzes,” Yepiskoposyan said.
SINGAPORE: Singapore reported five new cases of COVID-19 infection, the Ministry of Health (MOH) said in an update on Saturday (Feb 15).
Of these, three are linked to the cluster at Grace Assembly of God church; one is linked to the cluster at Seletar Aerospace Heights construction site and the other case is linked to a previous case.
Mobile World Congress, or MWC, was going to proceed because there were still 2,800 exhibitors. Now it’s being canceled.

Australian researchers have for the first time shown that weights training can protect the parts of the brain vulnerable to Alzheimer’s disease.
Acarbose and Metformin are commonly used to treat type 2 diabetes, but now they are also being tested for anti-aging effects, and according to the researchers these two FDA approved drugs have big promise.
In mice testing Acarbose and Metformin were demonstrated to increase health, lifespan, and longevity of the animals. These two drugs are now being tested in monkeys that have a similar physiology, reproductive system, and aging pattern as humans, in research being conducted at Texas Biomedical Research Institute which is supported by a pilot grant provided by the San Antonio Claude D. Pepper Older Americans Independence Center.
“I think this type of research can change what life is like for geriatric people,” said Corinna Ross, Ph.D, Associate Professor, Southwest National Primate Research Center at Texas BioMed.

A new study published in mSystems, a journal from the American Society for Microbiology, shows that the skin and mouth microbiomes are better predictors of age than the gut microbiome.
A very broad study

The FDA has cleared the world’s first portable MRI system, designed to be wheeled to a hospital bedside for scanning a patient’s head and brain.
Developed by Hyperfine Research for people age two and older, the point-of-care imaging system weighs about one-tenth that of a conventional, fixed MRI system. About three feet wide and five feet tall, the device fits in an elevator and runs off an everyday power outlet to create both clinical contrast images and 3D renders.
“More than 40 years after its first use, MRI remains a marvel. Unfortunately, it also remains inaccessible,” Hyperfine Chief Medical Officer Khan Siddiqui said in a statement. “It’s time that MRI made the jump to point of need just like X-ray and ultrasound have before it.”
The generation of a chemical system capable of replication and evolution is a key objective of synthetic biology. This could be achieved by in vitro reconstitution of a minimal self-sustaining central dogma consisting of DNA replication, transcription and translation. Here, we present an in vitro translation system, which enables self-encoded replication and expression of large DNA genomes under well-defined, cell-free conditions. In particular, we demonstrate self-replication of a multipartite genome of more than 116 kb encompassing the full set of Escherichia coli translation factors, all three ribosomal RNAs, an energy regeneration system, as well as RNA and DNA polymerases. Parallel to DNA replication, our system enables synthesis of at least 30 encoded translation factors, half of which are expressed in amounts equal to or greater than their respective input levels. Our optimized cell-free expression platform could provide a chassis for the generation of a partially self-replicating in vitro translation system.
