The COVID-19 pandemic has shined a spotlight on another US medical emergency: a serious shortage of nurses.
Because Pfizer-BioNTech and Moderna vaccines have been developed in record time, many wonder whether companies cut corners or compromised safety.
Detection of a virus in wastewater implies the presence of infected people in a community. It's not quite so simple though.
COVID-19 cases are skyrocketing across the US. Testing has ramped up over the past few months, but increasing hospitalizations, deaths and test-positivity rates show that the virus is out of control.
There are two new COVID-19 vaccines that appear to be more than 90% effective. But what are these vaccines, and how are they different from those used previously?
As viruses are transmitted from person to person they are constantly mutating and replicating. Could the SARS-CoV-2 virus evolve to evade the new vaccines that have just been developed?
Monoclonal antibodies are synthetic molecules manufactured in the lab. But do we need them if a vaccine is on its way?
Distributing a vaccine is a bit like boarding a plane — we can’t all board at the same time. So who gets priority? There are a few reasons we should consider vaccinating older people first.
Higher levels of stress was just one of the reasons the hearing problem may have worsened for many people.

As the coronavirus pandemic continues, and the colder weather approaches, new mathematical models are needed to study changing social behaviours and indoor spaces.
Novel plastics can rid themselves of germs using only air and light.
Are antibodies that attack a patient's own organs contributing to severe forms of COVID-19? A new study suggests specific antibody tests that may reveal the answer.
Scientists in the UK and Germany discovered a new doorway that the COVID-19 virus uses to infect human cells. This reveals new therapeutic possibilities for blocking the virus.
Over the approaching holidays, people around the world will want to travel to see friends and family. Getting tested for the coronavirus can make this safer, but testing alone is not a perfect answer.
An optical sensor that can detect individual molecules promises early detection of diseases and environmental contamination.
Hand hygiene is a critical part of the response to COVID-19. Washing hands at regular intervals during the day is essential. If water and soap are unavailable, hand sanitisers are an alternative.
A previous version of Melbourne's COVID roadmap flagged an exclusive bubble between two households. The new plan allows residents to have two adult visitors per day, which is far riskier.
Law enforcement is a blunt tool to achieve social conformity with COVID-safe rule. It's time to start thinking about other strategies to promote new norms.
Scientists handle virus samples every day but infections are incredibly rare – here's why.
