DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Researchers use genomic sequencing technique to detect presence of various microbes

About 12,000 bacteria and viruses collected in a sampling from public transit systems and hospitals around the world from 2015 to 2017 had never before been identified, according to a study by the International MetaSUB Consortium, a global effort at tracking microbes that is led by Weill Cornell Medicine investigators.

CASdetec: new CRISPR-based SARS-CoV-2 detection platform detects nucleic acids with high sensitivity and specificity

To add to existing CRISPR-based nucleic acid detection protocols, a team of researchers recently established a new SARS-CoV-2 detection protocol based on their previously reported platform - CDetection (Cas12b-mediated DNA detection). They combined nucleic-acid amplification methods and sample treatment protocols with CDetection and established an integrated nucleic acid detection platform called CRISPR-assisted detection or CASdetec. CASdetec has a detection limit of 1×104 copies/mL for SARS-CoV-2 pseudovirus, without any observed cross-reactivity.

New study may pave way for novel therapeutic strategies for COVID-19

An international and multidisciplinary team led by researchers at the University of Oxford, University of Glasgow, and University of Heidelberg, has uncovered the interactions that SARS-CoV-2 RNA establishes with the host cell, many of which are fundamental for infection.

New testing protocol for SARS-CoV-2 can process thousands of samples within 48 hours

Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.

Study shows that telomeres shorten most rapidly during early childhood

Telomeres are protective caps on DNA that shorten as we grow older. Now, one of the first studies to examine telomere length (TL) in childhood finds that the initial setting of TL during prenatal development and in the first years of life may determine one's TL throughout childhood and potentially even into adulthood or older age.

The potential therapeutic value of CDK6 inhibitors in critical COVID-19

While drug repurposing has been explored in the context of the current coronavirus disease 2019 (COVID-19) pandemic, the success of this strategy has been limited so far. A new study, released as a preprint on the medRxiv* server, describes a new method of identifying a promising hit among drugs already in use.
