Frog brain discovery may pave the way for repairing birth defects in humans

A team of researchers from Tufts University, Universitat de Valencia, and Harvard University has discovered that the brains of developing frog embryos damaged by nicotine exposure can be repaired by using “ionoceuticals” that can help in the recovery of bioelectric patterns in the embryo.

Prediction of incubation period for COVID-19 and other viruses

A new study published on the preprint server bioRxiv* in May 2020 provides a method to estimate the incubation period for any new pathogen, which could help to define the optimal quarantine period necessary to keep the spread of the causative agent in check.

COVID-19 in farmed Mink in the Netherlands

A new study published on the preprint server bioRxiv in May 2020 reports the development of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in farmed mink in two locations in the Netherlands.

Study shows how RNA editing affects the replication of COVID-19 virus

Two human deaminase enzymes edit the RNA of the SARS-CoV-2 virus when it enters a patient's body, with implications for the evolution of the virus and the spread of the infection, according to a new study.

Human immune repertoire may not commonly produce cross-neutralizing antibodies to coronaviruses

Patients infected with either severe acute respiratory syndrome coronavirus (SARS-CoV) or SARS-CoV-2 produce antibodies that bind to the other coronavirus, but the cross-reactive antibodies are not cross protective, at least in cell-culture experiments, researchers report May 17 in the journal Cell Reports.

Host-virus interaction drives adaptive mutation in bat CoV related to SARS-CoVs

Virus and receptor diversity is shaped by the need to evolve advanced weaponry to facilitate virus entry and infection, on the one hand, and host resistance, on the other. A new paper published on the preprint server bioRxiv* shows how this mechanism operates in a bat coronavirus, which is related to the earlier SARS coronavirus.

SARS-CoV-2 cell entry affinity varies across different host species

A new study from India, currently available on the preprint server bioRxiv*, estimated the probability and readiness of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to infect cells of different animal species – and revealed many of them that could act as disease carriers.

Study provides genetic explanation behind the sex bias observed in certain diseases

Some diseases exhibit a clear sex bias, occurring more often, hitting harder or eliciting different symptoms in men or women.

Genomic sequences from all over the world help fight SARS-CoV-2

As the COVID-19 pandemic rages across the world, killing hundreds of thousands and infecting over 4.1 million, researchers are racing against time to understand the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The SARS-CoV-2 genome has now been sequenced in many different regions of the world, and researchers are collaborating by sharing information to better understand the make-up and mutations that the virus has undergone.

SARS-CoV-2 in wastewater and rivers

A new study published on the preprint server medRxiv in May 2020 shows that while the virus causing COVID-19 may be present in wastewater and rivers, the biological agent is typically devoid of vitality and unable to cause active infection. This should provide some relief to public health authorities in their quest to contain the virus.

SARS-CoV-2 genome shows mutation hotspots and type-specific distribution

Now, a new study published on the preprint server bioRxiv reports on a large scale analysis of SARS-CoV-2 genomes and reveals a clonal geo-distribution and rich genetic variations.

5 May 2020

Study reveals variable sites in novel coronavirus SARS-CoV-2

Understanding the varying aggressiveness of SARS-CoV-2 may provide valuable data to trace its spread across populations. In the study, published on the preprint server BioRxiv, the researchers traced amino acid variants that possess high frequency in Europe, particularly in Italy, one of the hardest-hit countries.

Research reveals mechanism underlying Parkinson's dyskinesia

Many people with Parkinson's disease eventually develop debilitating movements called dyskinesia, a side effect of their much-needed dopamine replacement medication.

3 May 2020

Study reveals SARS-CoV-2 RNA cap structure

A new study published on the preprint server bioRxiv in April 2020 reports the discovery of the structure of the cap created by the novel coronavirus on virally encoded mRNAs. The finding could help create new antiviral strategies.

Researchers re-purpose cancer-fighting artificial antibodies for COVID-19

Researcher Paula Bates, John Trent, and Don Miller developed a therapeutic drug that could potentially block the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for the COVID-19 pandemic. Their research was initially aimed at helping patients suffering from multiple types of cancer.

Genomic sequencing shows COVID-19 spread patterns

Throughout the spread of the virus, genomic sequencing has played a role in epidemiologic tracking of the viral strains carried all over the world. Such strains are traced back to their origin by their unique mutations and help to link remote infections.

Coronavirus has mutated into at least 30 variants

The coronavirus disease (COVID-19) continues to threaten millions of people across the globe, and lockdowns appear set to remain in place in many countries amid rising death tolls, as governments decide whether to extend restrictions aimed at reducing the spread of the virus. Now, a new study reveals that the novel coronavirus has mutated into at least 30 different genetic variants, affecting different parts of the world.
