My international research project was put on hold – so I volunteered to become a COVID-19 tester. Here's what I learned.

Vaccine development usually spans a number of decades. This is because there's a need to understand the mechanisms of protection against the pathogen, and to minimise adverse reactions.
COVID-19 has been linked to neurological problems in those with severe disease.

As if the symptoms of COVID-19 were not disturbing enough, physicians have noted a rare neurological condition that emerges during some severe cases of this viral infection.
239 scientists have penned an open letter to the WHO arguing COVID-19 likely spreads through the air. But what is airborne transmission, and how strong is the evidence COVID-19 spreads this way?
Daily deaths from COVID-19 have rarely been below 600 in the U.S. since March.

There's no scientific definition for a wave of disease – and no evidence that the original onslaught of coronavirus in the US has receded much at all.
A high-profile paper
on the risks of hyrdoxychloroquine was recently and rightfully retracted.

Severe scrutiny of two major papers, including one about the effectiveness of hydroxychloroquine, is part of science's normal process of self-correction.
Saliva testing is less sensitive than a nasal swab. But in the midst of a public health crisis, in some cases a test with slightly reduced sensitivity may be better than no test at all.
Pooled testing is most efficient when applied in settings of low virus prevalence.
Pooling samples means one test can screen multiple people.

Screening multiple samples with a single test gets more people diagnosed using fewer supplies. Two health policy researchers explain how it works and how it could help the US.
We are slowly figuring out which drugs and therapies are effective against the new coronavirus.

During the last six months, news reports have mentioned dozens of drugs that may be effective against the new coronavirus. Here we lay out the evidence and reveal which ones are proven to work. Or not.
The U.S. as a whole is facing a huge surge in coronavirus cases, but the differences between states like New York and Florida are striking.

The recent spike in new coronavirus cases in the US is not due to a second wave, but simply the virus moving into new populations or surging in places that opened up too soon.
If a return to the office is on the cards, both employers and employees have a role to play in minimising the risk of COVID-19 spread.
SARS-CoV-2 turns on a cellular switch to build the tubes in this photo – called filopodia – that might help viral particles – the little spheres – spread more easily.

Kinases are cellular control switches. When they malfunction, they can cause cancer. The coronavirus hijacks these kinases to replicate, and cancer drugs that target them could fight COVID-19.

A simple computer model shows that safety measures can significantly impact both the exponential spread of COVID-19 and mortality rates.

China’s attempts to promote its actions and model of governance while discrediting the EU are not a short-term response to the pandemic, but part of a long-term strategy to build its international power.
Ongoing testing, say the authors, is critical to bringing back amateur sports.

Is it possible that people who recover from COVID-19 will be plagued with long term side effects from the infection? An infectious disease physician reviews the evidence so far.
Today smallpox can only be found in deep freeze inside a few highly secured laboratories, like this one at the CDC in 1980.
The smallpox virus appears to have been with humanity for millennia before a global vaccination drive wiped it out. Current genome research suggests how smallpox spread and where it came from.
Doctors reported the first cases of MIS-C in April. Learning more about how SARS-CoV-2 affects children is essential to the safe reopening of communities.

A rare new disease syndrome appears to be caused by an overactive immune response in children, often hitting weeks after exposure to the SARS-CoV-2 virus.
Screening for symptoms can catch some cases of COVID-19, but about people who are infected but not showing any symptoms?

There is a lot of confusion and concern around asymptomatic spread of SARS-C0V-2. An infectious disease expert explains how many people are asymptomatic and how they can spread the virus.
