Direct evidence in hamsters shows SARS-CoV-2 is airborne

Evidence suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be transmitted without contact by respiratory droplets and aerosols bearing the virus when coughing, sneezing, speaking, and breathing. The virus has been cultured from aerosols collected nearby COVID-19 patients, and such aerosols can linger in still air for hours.

Certain intestinal bacteria induce cross-reactive IgA responses to the SARS-CoV-2 spike RBD

A new study finds that human gut bacteria can induce antibodies of the immunoglobulin A (IgA) subtype that cross-react with the SARS-CoV-2 spike RBD.

World-first trial of third dose COVID-19 booster vaccine shows improved protection in transplant patients

Scientists with the Ajmera Transplant Centre at UHN have conducted a first-in-the-world randomized placebo-controlled trial of third dose COVID-19 booster vaccine for transplant patients that shows substantially improved protection.

Enzyme acts as a sensor to find the hiding spots of viruses

While some types of RNA viruses cloak themselves to hide inside a cell and create copies of themselves, a "detective enzyme" might be attuned to their whereabouts. A slight variation in their genomic code gives some people's cells the capacity to produce this sensor.

Study exposes the dire need for new clinical risk management tools to prevent COVID-19 deaths

A new study exposes the dire need for new clinical risk management tools to help hospital healthcare workers prevent the deaths and intensive care admissions of Black, Asian and minority ethnic (BAME) COVID-19 patients with pneumonia, say researchers.

Understanding how to regulate key enzyme may lead to new treatments for cancers, viral infections

A new study led by University of California, Irvine (UCI) researchers identifies two ways in which APOBEC3A - a vital enzyme that is responsible for genetic changes resulting in a variety of cancers while protecting our cells against viral infection - is controlled.

Excess COVID-19 cases, deaths in the U.S. may be attributable to PM2.5 pollution from wildfires

Thousands of COVID-19 cases and deaths in California, Oregon, and Washington between March and December 2020 may be attributable to increases in fine particulate air pollution (PM2.5) from wildfire smoke, according to a new study co-authored by researchers at Harvard T.H. Chan School of Public Health.

‘I don’t want to risk my life for a paycheck’: Immunosuppressed people grapple with returning to work

Elizabeth Groenweghe got a kidney transplant 14 years ago. She now takes several medications to prevent her body from rejecting her transplant organ. But these medications also weaken her immune system, putting her at higher risk of becoming seriously ill if she catches covid-19.

L452R mutations may have triggered the emergence of several COVID-19 variants

Most of the recently risen coronavirus variants of interest or concern -- delta, kappa, epsilon, iota and lambda -- are universally carrying a mutation in amino acid L452 of the Spike protein that helps the virus bind to host cells.
