A daily pill to treat covid could be just months away, scientists say

Within a day of testing positive for covid-19 in June, Miranda Kelly was sick enough to be scared. At 44, with diabetes and high blood pressure, Kelly, a certified nursing assistant, was having trouble breathing, symptoms serious enough to send her to the emergency room.

Researchers discover how Rift Valley fever virus enters cells

Rift Valley fever virus causes economically devastating outbreaks of hemorrhagic fever in livestock such as sheep, goats and cattle.

Infections impact blood vessel repair within the meninges following TBI or other cerebrovascular injuries

Viral Infection Slows Blood Vessel Repair After TBI: Seven days after mTBI, the blood vessels (stained in red) in the tissues around the brain are not completely repaired. A marker for intact vessels was used (labeled in green) to distinguish fully functional blood vessels (yellow) from ones that are still damaged (red).McGavern Lab, NINDS

Research shows ozone as a potential disinfectant agent in public transport

The Hydrens team of researchers developed a numerical model that estimates the ozone concentration needed to meet the disinfection criteria. To do this, it takes into account the geometry and volume of the space to be treated, the type of materials inside it and their capacity to absorb ozone, and the characteristics of the impulsion-distribution system used.

Human milk antibodies elicited by vaccination show reduced activity against SARS-CoV-2 VoCs

In a study recently published on the medRxiv* preprint server, scientists from Singapore have assessed the levels of IgA-specific anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in the breast milk of women recently immunized with the second dose of an mRNA-based coronavirus disease 2019 (COVID-19) vaccine.

Exploring the polymerase of poxviruses at an atomic level

Poxviruses have found a unique way of translating their genes into proteins in the infected organism. A team of researchers from Würzburg shows for the first time how the molecular machinery involved works at an atomic level.

Johns Hopkins Medicine mathematical model to play major role in ending HIV nationwide

A new Johns Hopkins Medicine mathematical model to predict how the human immunodeficiency virus (HIV) spreads in urban areas will play a major role in a federal initiative aiming to reduce the incidence of HIV infections in the United States by 90% between 2020 and 2030.

Using air filtration to remove airborne SARS-CoV-2 and other microbial aerosols in COVID wards

University of Cambridge researchers conducted a study in two repurposed COVID-19 units in Addenbrooke’s Hospital, Cambridge, UK, between January and February 2021. During this time, the alpha variant (lineage B1.1.7) accounted for >80% of the circulating SARS-CoV-2. This study, posted to the medRxiv* preprint server, aimed to provide evidence of the removal of SARS-CoV-2 and microbial bioaerosols using portable air filters with UV sterilization.

Mathematical constructions of SARS-CoV-2 action could help fine-tune prevention and treatment

Mathematical constructions of the action of SARS-CoV-2 and its multiple spikes, which enable its success at infecting cells, can give vaccine developers and pharmaceutical companies alike a more precise picture of what the virus is doing inside us and help fine tune prevention and treatment, mathematical modelers say.

New methodology for evaluating transmissibility and competitive advantages of co-circulating SARS-CoV-2 variants

A new study examines how SARS-CoV-2 variants confer a competitive advantage on the virus, fueling further transmission and mortality.

People with natural immunity and subsequent mRNA vaccination can neutralize viral particles capable of resisting vaccine-induced antibodies

New research suggests SARS-CoV-2 spike protein substitution mutations can create a replication-defective viral particle that makes the virus resistant to vaccine-induced antibodies.
