Revealed: how COVID-19 variants hijack human cells

University of Helsinki
Peer-Reviewed Publication

Finnish scientists have studied how different COVID-19 variants take over human cells to help the virus spread. By understanding this, we can find better ways to stop the virus with new treatments.

The first mouse strain that is susceptible to severe COVID-19 without genetic modification has been identified

Jackson Laboratory
Peer-Reviewed Publication

Researchers at The Jackson Laboratory and Trudeau Institute have identified the first mouse strain that is susceptible to severe COVID-19 without the need for genetic modification. This development, reported in Scientific Reports, marks a pivotal step forward in infectious disease research, providing an essential tool to develop vaccines and therapeutics for future coronavirus variants and potential pandemics.

Psilocybin therapy helps clinicians process COVID despair

University of Washington School of Medicine/UW Medicine
Peer-Reviewed Publication

Psilocybin-assisted psychotherapy resulted in significant reductions in depression among clinicians who provided front-line COVID-19 care in 2020 and 2021. These reductions were measurably greater than those experienced by the cohort of clinicians who received a placebo instead. Findings from this double-blind, randomized clinical trial are to be published in JAMA Network Open at 8 a.m. PST Thursday, Dec. 5.

“For doctors and nurses who feel burned out or disillusioned or disconnected from the patient care they want to provide, this study shows that psilocybin therapy is safe and can help these clinicians work through those feelings and get better,” said Dr. Anthony Back, the lead investigator.

Study uses game theory to rethink our pandemic responses

Dartmouth College
Peer-Reviewed Publication

Dartmouth researchers use game theory to propose a new way of thinking about masking and social distancing rules that is more responsive to public sentiment and may help increase cooperation. The study is the first to consider mask wearing and social distancing as competing actions that people respond to differently, which would give public health officials more flexibility to adapt to epidemics.

Why some individuals believe fake news and conspiracies

PLOS
Peer-Reviewed Publication

People who are credulous are less capable of recognizing fake news, and along with mistrustful adults, are more susceptible to conspiracy thinking and vaccine hesitancy, according to a study published December 4, 2024, in the open-access journal PLOS Global Public Health by Michal Tanzer and colleagues from University College London, U.K.

Researchers design a therapeutic tool to inhibit the proliferation of the SARS-CoV-2 virus that causes COVID-19

University of Barcelona
Peer-Reviewed Publication

A study led by the University of Barcelona and the Spanish National Research Council’s Institute for Advanced Chemistry of Catalonia (IQAC - CSIC) presents a new therapeutic tool capable of inhibiting the proliferation of the SARS-CoV-2 virus that causes COVID-19. The results open up new perspectives in the fight against this coronavirus and other viral diseases that still have no medical treatment, such as the Crimean-Congo haemorrhagic fever (CCHFV).

COVID infection and age-related blindness

PNAS Nexus
Peer-Reviewed Publication

An experimental study in mice shows that SARS-CoV-2 infection can damage the retinas. According to the authors, SARS-CoV-2 infection could thus accelerate the onset and progression of age-related blindness.

Pregnancy enhances natural immunity to block severe flu

McGill University
Peer-Reviewed Publication

McGill University scientists have discovered that pregnancy may trigger a natural immunity to boost protection against severe flu infection. Contrary to the common belief that pregnancy increases vulnerability to infections, researchers found that it strengthened an immune defense in mice, blocking the Influenza A virus from spreading to the lungs, where it can cause severe infection.

Study details surprising biological mechanisms underlying severe COVID-19

Weill Cornell Medicine
Peer-Reviewed Publication

Severe COVID-19 arises in part from the SARS-CoV-2 virus’s impact on mitochondria, tiny oxygen-burning power plants in cells, which can help trigger a cascade of organ- and immune system-damaging events, suggests a study by investigators at Weill Cornell Medicine, Johns Hopkins Medicine, Children’s Hospital of Philadelphia, and the University of Pittsburgh School of Medicine, along with other members of the COVID-19 International Research Team.

Study untangles how COVID-19 wreaks widespread damage in the body

University of Pittsburgh
Peer-Reviewed Publication

New research sheds light on the pathways that drive organ damage and death in severe COVID-19 and helps explain why survivors of the disease can experience long-term complications.

Brief scientific literacy interventions may quash new conspiracy theories

Penn State
Peer-Reviewed Publication

The more time you spend on social media, the likelier you are to have come across a viral post that seems too strange to be true. Brief scientific literacy interventions, especially those that focus on critical thinking skills, may help to undermine conspiracy beliefs and behaviors before the conspiracy theories have a chance to take root, according to a team led by Penn State researchers.

A cause of hyperinflammatory response in lethal COVID-19 identified

Johns Hopkins Medicine
Peer-Reviewed Publication

As part of the COVID-19 International Research Team, researchers at the Johns Hopkins Kimmel Cancer Center, Children’s Hospital of Philadelphia, the University of Pittsburgh and Weill Cornell Medicine discovered a novel cause of cytokine storm — the extreme inflammatory response associated with increased risk of death in COVID-19 infection.
