Present work shows that both electrostatic and hydrophobic interactions play a key role at the graphene/coronavirus interfaces and such materials can efficiently protect cells from coronavirus infect...

Nearly 70,000 cases of covid infection were reported yesterday, 8th January. Of course that’s officially confirmed cases and the real number of infections will be much higher. A small but sig…

In most social and information systems the activity of agents generates rapidly evolving time-varying networks. The temporal variation in networks' connectivity patterns and the ongoing dynamic processes are usually coupled in ways that still challenge our mathematical or computational modelling. Here we analyse a mobile call dataset and find a simple statistical law that characterize the temporal evolution of users' egocentric networks. We encode this observation in a reinforcement process defining a time-varying network model that exhibits the emergence of strong and weak ties. We study t...

Reopening schools is an urgent priority as the COVID-19 pandemic drags on. To explore the risks associated with returning to in-person learning and the value of mitigation measures, we developed stochastic, network-based models of SARS-CoV-2 transmission in primary and secondary schools. We find that a number of mitigation measures, alone or in concert, may reduce risk to acceptable levels particularly when community prevalence is low. Student cohorting, in which students are divided into two separate populations that attend in-person classes on alternating schedules, can reduce both the li...

The illness ME/CFS has been repeatedly tied to infectious agents such as Epstein Barr Virus. Expanding research on the human microbiome now allows ME/CFS-associated pathogens to be studied as interacting members of human microbiome communities. Humans harbor these vast ecosystems of bacteria, viruses and fungi in nearly all tissue and blood. Most well-studied inflammatory conditions are tied to dysbiosis or imbalance of the human microbiome. While gut microbiome dysbiosis has been identified in ME/CFS, microbes and viruses outside the gut can also contribute to the illness. Pathobionts, and...

Background The lack of precise estimates on transmission risk hampers rational decisions on closure of educational institutions during the COVID-19 pandemic. Methods Secondary attack rates (SARs) for schools and day-care centres were calculated using data from state-wide mandatory notification of SARS-CoV-2 index cases in educational institutions and information on routine contact tracing and PCR-testing. Findings From August to December 2020, every sixth of overall 784 independent index cases caused a transmission in educational institutions (risk 0.17, 95% CI 0.14-0.19). In a subgroup, mo...

A Nature survey shows many scientists expect the virus that causes COVID-19 to become endemic, but it could pose less danger over time.

Here, Veldhoen and Simas discuss why immunity to SARS-CoV-2 in populations may ultimately be driven by the endemic presence of the virus and not rely on continued mass vaccination programmes.
