Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

Using saliva to predict COVID-19 severity in children

News-Medical speaks to Dr. Usha Sethuraman about her research into COVID-19 and how saliva could be used to help predict COVID-19 severity in children.

Honeybees can be trained to identify SARS-CoV-2 infected samples, say scientists

In a recent study published on the bioRxiv* pre-print server, researchers from the Netherlands successfully trained honeybees (Apis mellifera) to identify severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected minks (Neovison vison) using Pavlovian conditioning protocols.

Improper Z-RNA recognition contributes to pathogenesis of Aicardi-Goutières syndrome

Like DNA, RNA molecules contain information through unique combinations of four different nucleotides. However, through a molecular process called RNA editing, chemical changes can be made to adenosine nucleotides that convert them to a nucleotide called inosine by enzymes known as adenosine deaminases (ADARs).

Research reveals the mechanisms of cardiac sex disparities at an early stage

Males and females differ in prevalence, treatment responses, and survival rates for a variety of diseases. For cardiac disease, women almost uniformly fare far worse than men. There are likely many reasons for this, and scientists at the University of North Carolina at Chapel Hill and Princeton University seemed to have found one deep inside cells before we're even born.

Adding RNA-inspired ‘breaking points’ to polymer for preventing plastic pollution

Once plastic products are used and discarded, they can linger in oceans, collecting in large "garbage patches" and harming sea life. One potential solution, a biodegradable polymer called polylactide (PLA), has so far not fully lived up to its promise, showing little sign of breakdown once in seawater.

Regular testing of SARS-CoV-2 positive vaccinated HCWs may reduce need for long quarantines

A new study published in the journal Annals of Internal Medicine conducted systematic surveillance involving 2,397 HCWs who were fully vaccinated with the Pfizer-BioNTech BNT162 vaccine at the ASST Settelaghi hospitals, Italy, in February 2021.

Study highlights the critical role of junk DNA in mammalian development

Nearly half of our DNA has been written off as junk, the discards of evolution: sidelined or broken genes, viruses that got stuck in our genome and were dismembered or silenced, none of it relevant to the human organism or human evolution.
