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 design 3D map to understand the behavior of novel coronavirus

To better understand how the novel coronavirus behaves and how it can be stopped, scientists have completed a three-dimensional map that reveals the location of every atom in an enzyme molecule critical to SARS-CoV-2 reproduction.

Mathematical model for COVID-19 allows for dynamic social distancing and relaxation

Recently, researchers from York University, Toronto, Canada, presented a mathematical model for COVID-19 comprising groups of people with various levels of exposure to the disease based on data from Ontario, Canada. Their work is published on the preprint server medRxiv.

Research examines COVID-19 transmission patterns in Georgia, U.S.

Researchers from Emory University and the Georgia Department of Public Health have shown that the transmission of coronavirus disease 2019 (COVID-19) in the state of Georgia earlier this year changed over time and varied by age.

Frequent testing and isolation/quarantine essential to contain COVID-19

A recent study by researchers at Virginia Tech and Central China Normal University published on the preprint server medRxiv in October 2020 discusses the various interventions required and the level of control required, whether to flatten the curve or reduce the case number.

Dietary supplement represents an innovative strategy to help in the fight against SARS-CoV-2

SPIN (SPermidin and eugenol INtegrator for contrasting incidence of coronavirus in EU population) is a European project powered by EIT Food that is currently developing a dietary supplement supporting the function of the immune system in the fight against SARS-CoV-2 infections in population at high risk.

Sony introduces new LMD-X3200MD medical grade LCD monitor

Sony has today introduced the LMD-X3200MD 32-inch medical grade LCD monitor, enhancing surgical workflow with 4K HDR color imaging and innovative technology.

Scientists show why zebra finches have problems with reproduction

In birds and other species alike, pairs can face considerable difficulties with reproduction. Scientists at the Max Planck Institute for Ornithology in Seewiesen have now shown in an extensive analysis of 23,000 zebra finch eggs that infertility is mainly due to males, while high embryo mortality is more a problem of the females.

Study could offer important clues on factors affecting human microbiome rhythms

Nearly every organism hosts a collection of symbiotic microbes--a microbiome. It is now recognized that microbiomes are major drivers of health in all animals, including humans, and that these symbiotic systems often exhibit strong daily rhythms.

Study shows concerning levels of COVID-19 vaccine hesitancy

More than a third of people (34%) in Turkey and one sixth of people (17%) in the UK are 'hesitant' about a COVID-19 vaccine, according to a study by UCL and Dokuz Eylul University in Turkey.

Exposure to ancient parasites may be linked to humans’ response to coronavirus

Why are some people more resilient to viruses than others? The answer has eluded scientists for centuries and, in the age of COVID-19, has come to represent one of the holy grails of biomedical research.

Researchers develop ViDok app to test potential COVID-19 treatments

Anyone with a smartphone can download the app ViDok, which lets users pick from a library of molecules that might bind to key proteins on the SARS-CoV-2 virus, which causes COVID-19, and then can tweak the molecules to try to find a better fit.

Optimizing allocation of future COVID-19 vaccine can double effectiveness

In anticipation of coronavirus disease (COVID-19) vaccine deployment, the Australian and US researchers utilized an age-structured mathematical model to appraise the potential benefits of optimizing age-specific dose allocation for suppressing SARS-CoV-2 transmission – and reaffirmed the notion that vaccination alone may be inadequate to achieve herd immunity in some settings. The study is currently available on the medRxiv* preprint server.

Penn receives $4.5 million NIH grant to create a comprehensive resource for women’s health

Junhyong Kim, PhD, Chair and Patricia M. Williams Professor of Biology in the School of Arts and Sciences, and Kate O'Neill, MD MTR, Assistant Professor, Department of Obstetrics and Gynecology in the Perelman School of Medicine, have been awarded a Human BioMolecular Atlas Program (HuBMAP) grant supported by the Eunice Kennedy Shriver National Institute of Child Health & Human Development and the Common Fund of the National Institutes of Health.

Study estimates lower herd immunity to SARS-CoV-2 in the U.S.

A new study shows that recognizing the differences in the population composition, connectedness and distribution, as well as inter-individual differences in immunity, susceptibility and infectivity, are crucial to estimating the herd immunity attained as a result of natural severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) more accurately.

Transmission dynamics of COVID-19 in two Indian states

Indian and American researchers collaborated to study the trends of transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in two Indian states – Tamil Nadu and Andhra Pradesh. Their study titled, “Epidemiology and transmission dynamics of COVID-19 in two Indian states,” was published in the latest issue of the journal Science last week.
