Mobile phone contamination could be part of SARS-CoV-2 transmission chain in hospitals, Brazil case study suggests

Researchers conducting a study at a coronavirus disease 2019 (COVID-19) intensive care unit (ICU) in São Paulo, Brazil, have warned that infection control guidelines need to include a universal policy regarding the disinfection of mobile phones in the hospital setting.

SARS-CoV-2 infection risk in day care centers for children and educators is low

Their findings suggest that SARS-CoV-2 infection rarely occurs in daycare centers, and thus, these centers should not be considered as potential reservoirs of the virus. The study is currently available on the medRxiv* preprint server.

SARS-CoV-2 viral antigens found in non-pulmonary tissues in recovering patients

A team of researchers in Singapore, led by Dr. Joe Yeong, and Prof. Tony Kiat Hon Lim, have reported the presence of residual SARS-CoV-2 ribonucleic acid (RNA) – the virus' genetic material – in stool samples and gastrointestinal tissues from patients recovering from the coronavirus disease 2019 (COVID-19).

Study shows SARS-CoV-2 infection four times more likely through household transmission than community

A group of researchers from across the United States working in collaboration with their Swiss counterparts have conducted an extensive population-based serological survey to understand the transmission dynamics of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) – the novel agent that causes coronavirus disease 2019 (COVID-19).

Improved diet and more physical activity during pregnancy modifies infants’ DNA

A new study has shown pregnant women with obesity could reduce the health risks for their infants through improved diet and more physical activity.

COVID-19 hospitalizations and deaths skew towards older males of non-European ancestry

A team of researchers recently investigated the genetic determinants of COVID-19 risk and severity in humans.

Study shows iscan method could be effective for rapid COVID-19 testing

A simple COVID-19 test kit combines virus amplification with a CRISPR-Cas system for effective SARS-CoV-2 detection. The kit, called iSCAN, uses reagents that can be locally manufactured.

Study may help develop effective drugs against COVID-19

Scientists at the University of Cambridge, in collaboration with Justus-Liebig University, Germany, have uncovered how the genome of SARS-CoV-2 - the coronavirus that causes COVID-19 - uses genome origami to infect and replicate successfully inside host cells.

Unrelated mutations can lead to false-positive results in men with advanced prostate cancer

Unrelated mutations, when present in the blood, can lead to false-positive results in men with advanced prostate cancer who are undergoing liquid biopsies.

Genomic surveillance of yellow fever outbreak in São Paulo

Yellow fever virus is normally confined to the Amazon region, but the virus circulated in the Southeast of Brazil between 2016 and 2018, causing the worst epidemic and epizootic outbreaks there for decades.

Researchers gain novel insights into the role of autophagy in neurons

It appears that autophagy protects our neurons in the brain, but evidently for entirely different reasons than previously assumed, as researchers from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) and Charité in Berlin have now shown.

Researchers pioneer new approach to treating life-threatening snake bites

A new approach of treating life-threatening snake bites responsible for around 100,000 deaths globally each year is being pioneered by an international research consortium led by University of Bristol scientists.

Researchers present overview of benefits from tree-sourced foods

Two of humanity's biggest problems - the climate crisis and abysmal eating habits - can partly be solved by one healthy solution: eating more food from trees, specifically tropical ones.

Study reveals new mechanism underlying immune-cell activation

When antibody-producing immune cells encounter infectious pathogens for the first time, they engage a signal cascade to generate a massive activation signal within seconds.

Novel insights on a common protein could have broad biomedical applications

A new University of Colorado Boulder-led study sheds light on a protein key to controlling how cells grow, proliferate and function and long implicated in tumor development.

An analysis of genetic diversity of D614G mutation in SARS-CoV-2

A new study published in the preprint server bioRxiv in November 2020 reports that the effect of the mutation is minimal, in terms of pathogenicity or altered response to neutralizing antibodies elicited against the native virus strain.

D614G mutation enhances stability of SARS-CoV-2 spike protein

A new study, published on the preprint server bioRxiv in November 2020 by researchers at the Indian Institute of Science, has explored this issue further. The researchers have found that this mutation is associated with structural and energetic changes that cause this spike variant to become more available during infection, thus rendering the associated strain more infective.
