States’ face-covering mandates leave gaps in protection

Brady Bowman, a 19-year-old student at the University of Colorado-Boulder, and two friends strolled down 11th Street, all sporting matching neck gaiters branded with the Thomas' English Muffins logo. He had received an entire box of the promotional gaiters.

Scientists conduct randomized trial to assess e-cigarette versus traditional cigarette use

Scientists and medical professionals have long debated whether pod e-cigarettes are a safer alternative to traditional cigarettes. A new study provides some insight.

Most COVID-19 convalescent individuals have long-lasting memory T cell responses

Recently, researchers from the Huazhong University of Science and Technology, China, and the University of Duisburg-Essen, Germany, conducted a comprehensive analysis of memory T cell responses against SARS-CoV-2 in individuals who have recovered from COVID-19.

SARS-CoV-2 deactivation on surfaces in 30 seconds with a copper paste

In a recent bioRxiv preprint paper, a team of researchers shows the possibility of using copper, in a new conformation, for effectively killing microbes immediately.

New understanding of glycan signatures of the SARS-COV-2 S1 spike protein

A team of scientists from the University of Oxford, UK, has revealed that site-specific glycosylation differs between spike proteins derived from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and a viral vector-based vaccine candidate.

Optimizing SARS-COV-2 inactivation for COVID-19 research at lower biosafety levels

Researchers at Montana State University have validated and compared two methods for inactivating the causative agent of coronavirus disease 2019 (COVID-19) that would enable the virus to be studied at a lower biosafety level (BSL) than the one currently required.

"Escape mutations" could help SARS-CoV-2 evade immune attack

Researchers in the United States have identified mutations within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – that can reduce antibody binding to the virus, potentially mediating its escape from immune attack.

Examining potential foodborne transmission of SARS-CoV-2 through fresh produce

To address this gap in knowledge, researchers from the Bureau of Microbial Hazards, Health Canada, and Faculty of Medicine, University of Ottawa examined the survival of human coronaviruses on the surface of fresh produce such as apples, cucumbers, and tomatoes.

Study: Pod e-cigarettes are less damaging to health than traditional cigarettes

Cigarette smoking causes more than 480,000 deaths each year in the United States, according to federal government data -- and some smokers find it nearly impossible to quit. Many of these smokers use regular, or combustible, cigarettes.

Vitamin D3 supplementation shows no therapeutic benefits in severe COVID-19 patients, study finds

A team of researchers at the University of São Paulo in Brazil aimed to determine if vitamin D3 supplementation reduces the length of stay in hospitalized patients with severe COVID-19.

Around 10 SARS-CoV-2 virions per cell in human body, study finds

A new study has found that there are about ten virus particles in each cell in the body. The research team from the Weizmann Institute of Science in Israel and the University of California in the USA estimate that each infected person carries around 109-1011 virions during peak infection.

Ancient East Asian peoples may have adapted to coronavirus-like epidemic up to 25,000 years ago

A new study by researchers at the University of Adelaide and Australian National University in Australia and the University of Arizona in the US shows that an ancient coronavirus-like epidemic drove the adaptation of East Asian peoples from 25,000 to 5,000 years ago.

How weather affects SARS-CoV-2 transmission: A US-based case study

How changes in the weather affect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the topic of several studies. The preoccupation of researchers with this aspect of the coronavirus disease 2019 (COVID-19) pandemic follows from observations that the flu virus and other coronaviruses follow seasonal patterns. Understanding how SARS-CoV-2’s transmissibility is affected by seasonal changes can thus help us to develop more informed preventative measures against its spread.

Study examines the diagnosis of exercise‐induced respiratory symptoms in children

Exercise-induced respiratory symptoms are common in childhood, and it can be difficult to diagnose their cause.

Around 30 percent of Australians hesitant to accept SARS-CoV-2 vaccine, study finds

A new study published on the preprint server medRxiv* in November 2020 suggests that a significant proportion of the Australian population is likely to show vaccine hesitancy. This indicates the need for public health messaging as well as, in some cases, other policy measures.

COVID-19 during pregnancy can cause placental inflammation and impaired immunity

A new study conducted by a team of researchers at Johns Hopkins University, USA, has observed how pregnant women infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) show stunted antiviral immune responses.

Severe COVID-19 complications linked to gut barrier breakdown

A new study claims that severe COVID-19 is caused by a positive feedback loop triggered by systemic inflammation and mediated by abnormal gut permeability. This finding could potentially help open up new avenues of treatment.
