Cost of Covid-19 tests plays key role in people’s willingness to undergo testing

Where and how long can schools remain open in times of the Corona pandemic? How safe are public transport means? Which rules must be observed when organizing events? To answer these questions, systematic tests for Corona infections and antibodies are of decisive importance.

Scientists warn Americans are expecting too much from a vaccine

The White House and many Americans have pinned their hopes for defeating the COVID-19 pandemic on a vaccine being developed at "warp speed." But some scientific experts warn they're all expecting too much, too soon.

Research finds a problem with concept of herd immunity in COVID-19

A recent study published on the preprint server medRxiv* in October 2020 suggests that arguments in favor of herd immunity are weakened by the fact that the steep increase in the number of COVID-19 deaths as a result of being exposed to the virus many times instead of once or a few times is not taken.

Scientists use experimental approach to identify genes and interactions

A phage is a virus that invades a bacterial cell. While harmless to human cells, phages are potentially deadly to bacteria since many phages enter a cell in order to hijack its machinery in order to reproduce itself, thus destroying the cell.

COVID vaccine misinformation lowering people's intent to get vaccinated

A new study by researchers at the Imperial College London and the London School of Hygiene and Tropical Medicine aimed to determine how online misinformation impacts COVID-19 vaccine uptake intent. Further, the team wanted to identify socioeconomic groups at a higher risk of not getting vaccinated and those who are most susceptible to online misinformation.

Myeloid cells can suppress immune response, promote brain metastasis

Scientists have long believed that the brain protects itself from an aggressive immune response to keep down inflammation. However, that evolutionary control may work against it when a cancer cell attempts to spread to the brain, researchers at the University of Notre Dame have discovered.

Study reveals sex-based differences in clearance of asymptomatic malaria infections

Females are able to clear asymptomatic malaria infections at a faster rate than their male counterparts, says a study published today in eLife.

Scientists identify new therapeutic targets for SARS-CoV-2

To identify new potential therapeutic targets for SARS-CoV-2, a team of scientists at the New York Genome Center, New York University, and the Icahn School of Medicine at Mount Sinai, performed a genome-scale, loss-of-function CRISPR screen to systematically knockout all genes in the human genome.

Impact of natural and vaccine-induced immunity could shape the future trajectory of COVID-19

New research suggests that the impact of natural and vaccine-induced immunity will be key factors in shaping the future trajectory of the global coronavirus pandemic, known as COVID-19.

COVID-19 vaccine tracker provides real-time updates on effective vaccine

McGill University professor Nicole Basta and her team have created an interactive online COVID-19 vaccine tracker, that provides real-time updates on progress in developing a safe and effective vaccine.

Lung biomarkers may predict severe COVID-19

Two University of New Mexico researchers postulate certain specific biomarkers' relevance in predicting the potential for progression to severe COVID-19 in a paper published on the preprint server bioRxiv*

Researchers identify effective way to protect vulnerable people from COVID-19

T-cells taken from the blood of people who recovered from a COVID-19 infection can be successfully multiplied in the lab and maintain the ability to effectively target proteins that are key to the virus's function, according to a new study published Oct. 26 in Blood.

About 15% of COVID-19-related deaths linked to long-term exposure to air pollution

Long-term exposure to air pollution has been linked to an increased risk of dying from COVID-19 and, for the first time, a study has estimated the proportion of deaths from the coronavirus that could be attributed to the exacerbating effects of air pollution for every country in the world.

Study better reveals the function and behavior of macrophages in cancer growth

Macrophages, cells that help engulf and destroy harmful organisms in the body, tend to be characterized as the Jekyll and Hyde of the immune system.

Phase 1 trial results of gorilla adenovirus vaccine for COVID-19

A recent study published on the preprint server bioRxiv* in October 2020 reports the development of a novel vaccine based on a simian adenoviral vector obtained from a group C gorilla isolate called GRAd32. This could help speed up vaccine development.

Startling high SARS-CoV-2 seroprevalence in Veracruz, Mexico

A surprising new study published on the preprint server medRxiv in October 2020 reports a very high seroprevalence of IgG antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the city of Vera Cruz, Mexico. They are among the highest to be reported anywhere in the world.

Mathematical modeling study offers new insights into optimal timing of antiviral therapies against COVID-19

A new mathematical modeling study by Ashish Goyal and colleagues, informed by data collected from 25 patients hospitalized with COVID-19 in 4 different countries, offers some important new insights into the optimal timing of 4 different antiviral therapies to combat the disease.

Neutrophils have more functions in the body than previously thought

Scientists at the Centro Nacional de Investigaciones Cardiovasculares have discovered that neutrophils, the most abundant cells of the innate immune system, have many more functions in the body than previously thought.

Study: 90% of patients have detectable antibodies up to 7 months post contracting COVID-19

A new study led by Marc Veldhoen, principal investigator at Instituto de Medicina Molecular João Lobo Antunes (iMM; Portugal) with an interdisciplinary team of clinicians and researchers from Faculdade de Medicina da Universidade de Lisboa (FMUL) and Centro Hospitalar Lisboa Norte (CHLN) and collaborators at Instituto Português do Sangue e Transplantação (IPST), shows that 90% of subjects have detectable antibodies 40 days up to 7 months post contracting COVID-19.
