Mask wearing, social distancing considerably reduce incidence of many diseases

Measures to reduce the spread of COVID-19 through non-pharmaceutical interventions (NPIs) such as mask wearing and social distancing are a key tool in combatting the impact of the ongoing coronavirus pandemic.

Immune-evading variants can emerge in SARS-CoV-2, researchers warn

An international team of researchers has shown that a mutation within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the coronavirus disease 2019 (COVID-19) – enables the pathogen to evade antibody-mediated immunity while maintaining replication fitness and increasing viral loads.

Study opens a new avenue for prophylactic anti-malarial strategies

A new study led by Maria Manuel Mota, group leader at Instituto de Medicina Molecular João Lobo Antunes (iMM; Portugal), now shows that malaria parasites secrete the protein EXP2 that is required for their entry into hepatocytes.

How escalating COVID cases forced one state to change its masking strategy

In Montana's conservative Flathead County, prosecutors and local leaders were turning a blind eye to businesses that flouted state mask and social distancing mandates, even as the area's COVID infections climbed to their highest levels.

New Zealand case study shows room for improvement in genomic sequencing of COVID-19 outbreaks

Researchers in New Zealand, the United States and Australia have demonstrated the effectiveness of real-time genomic sequencing at tracking the re-emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in New Zealand, in August this year.

Insulin has met an evolutionary cul-de-sac making most people vulnerable to Type 2 diabetes

Scientists have found that insulin has met an evolutionary cul-de-sac, limiting its ability to adapt to obesity and thereby rendering most people vulnerable to Type 2 diabetes.

Antiangiogenic drugs increase the aggressiveness of some kidney tumors

Angiogenesis is the process by which tumors create new blood vessels that will provide them the nutrients to continue growing.

Researchers explore how different birth experience affect the developing nervous system

It is an experience we all share, as miraculous as it is mysterious. Birth. Today, roughly one in three births in the United States occurs via cesarean section or C-section.

An analysis of genetic diversity of D614G mutation in SARS-CoV-2

A new study published in the preprint server bioRxiv in November 2020 reports that the effect of the mutation is minimal, in terms of pathogenicity or altered response to neutralizing antibodies elicited against the native virus strain.

People treated with statins have 22% to 25% lower risk of dying from COVID-19

Coronavirus has infected more than 40 million people around the world and has caused more than a million deaths in less than a year.

SARS-CoV-2 mutations becoming more contagious

A team of researchers working with Scott Wesley Long from Houston Methodist Hospital and colleagues from Texas, New York, and Illinois studied the patterns of genetic mutations of SARS CoV-2 and its impact on the second wave of infections worldwide.

Adaptive evolution of human coronaviruses may necessitate frequent reformulation of vaccines

Researchers from the Vaccine and Infectious Disease Division at the Fred Hutchinson Cancer Research Center, USA, have revealed that adaptive evolution in the antigenic regions facilitates seasonal coronaviruses to escape the host immune responses and to cause recurrent infections.

Some of the main osteoporosis treatments could have a protective effect against COVID-19

Some of the principal treatments for osteoporosis, denosumab, zoledronate and calcium, could have a protective effect against COVID-19 in patients who take them, specifically a 30 to 40% reduction in the rate of infection, according to the results of a joint study by Hospital del Mar, the Hospital del Mar Medical Research Institute (IMIM), Pompeu Fabra University and the Pere Virgili Health Park.

Researchers use sequencing data to study the key drivers of speciation, adaptation in corals

A new study led by the University of Hawai'i at Mānoa's Hawai'i Institute of Marine Biology (HIMB) revealed that diversity in Hawaiian corals is likely driven by co-evolution between the coral host, the algal symbiont, and the microbial community.

Global collaboration provides a COVID-19 disease map

A collaboration of researchers from 120 different institutes across 30 countries including France, Germany, Australia, Japan, USA, India, Turkey, Brazil, and Canada initiated an effort to develop a COVID-19 Disease Map - a collection of computational models and diagrams of molecular mechanisms implicated in COVID-19.

The Sun plays a role in the evolution of viral respiratory epidemics

Why do most viral epidemics spread cyclically in autumn and winter in the globe's temperate regions? According to an interdisciplinary team of researchers of the Italian National Institute for Astrophysics, the University of Milan, the Lombardy regional agency for the environment and the Don Gnocchi Foundation, the answer is intimately related to our Sun: their theoretical model shows that both the prevalence and evolution of epidemics are strongly correlated with the amount of daily solar irradiation that hits a given location on the Earth at a given time of the year.

Genomic sequence of the White House "superspreader" event

Now, a new study revealed the genetic signature of the SARS-CoV-2 that spread in the White House and most likely infected President Trump. The team applied genomic epidemiology to shed light on the origins of the outbreak

Human immune system may play key role in shaping the microbiome composition

The gut is an unusually noisy place, where hundreds of species of bacteria live alongside whatever microbes happen to have hitched a ride in on your lunch.

Penn State and Stanford University collaborate to develop two-hour sepsis test

One in three people who die in U.S. hospitals have sepsis, the body's extreme response to infection that can lead to multiple organ failure. Diagnosis can take up to five days, but death may take only hours from the initial onset of sepsis.

A2B-COVID: Rapid identification of SARS-CoV-2 transmission

A new study published on the preprint server medRxiv in October 2020 reports a method to assess transmission potential for any event in the current pandemic, using what is known about the virus's spread, data on the mobility of individuals, and new ways of processing genomic sequencing data. The outcome is to determine whether cases are linked or not so as to take action to prevent further spread.
