With COVID-19 cases soaring across the US and worldwide, the need for a vaccine could not be greater. Here's where we stand on vaccine development, including positive results from Pfizer's trial.
Jennifer Doudna and Emmanuelle Charpentier have been awarded the Nobel prize in Chemistry for their revolutionary work on 'gene scissors' that can edit DNA.
...and why Professor Chris Whitty is right.
Researchers are working on handheld devices that can signal the presence of SARS-CoV-2 in the air.

Miniaturized laboratory equipment is making it easier to identify airborne pathogens in the field, but there's still work ahead to be able to instantly determine if a room is safe or contaminated.
The polymerase chain reaction, or PCR, is used to copy strands of DNA.
COVID-19 tests rely on a process developed at a biotech company co-founded by a Canadian. Canada’s current testing expertise needs to be channelled to prepare for the next wave, and the next pandemic.
Did coronavirus arrive in Spain over a year ago?
Scientists in Spain have reported finding traces of the novel coronavirus in wastewater dating back to March 12, 2019.
What if you could test yourself for coronavirus with a test in the comfort of your home?

Testing for coronavirus has been a fiasco in the US. But now companies are developing super fast tests, including ones that might eventually be as simple as at home pregnancy tests.
Tiny parts of our genome once thought useless are being turned into ways to diagnose and treat disease.
A coronavirus vaccine is coming, but when?

Vaccine development is usually a long process. The coronavirus pandemic is forcing researchers to innovate and test potential vaccines faster than ever before.
Finding drugs that treat the COVID-19 coronavirus may be just as important as developing a vaccine. But it's much harder to create effective antivirals than antibiotics.
Testing in cells is an important and exciting first step.

Researchers at the University of California, San Francisco, identified nine existing drugs that show promise to treat COVID-19. The proteins they target haven't been tried before.
Why do scientists care about mutations on the coronavirus?

The SARS-CoV-2 virus that causes COVID-19 is constantly mutating. What do these mutations reveal about this virus's evolution? And will this knowledge help us to develop a long-lasting vaccine?
It seems as though every other day we're told a cure has been found for coronavirus. This is not strictly true – but there are some therapeutic options showing promise.
There are many ways to make a vaccine. In a time of crisis, the more paths towards success the better.

Under pressure to develop a coronavirus vaccine, researchers have turned to protein synthesis, genetics and hybrid viruses. It is likely a mix of these approaches will be used to fight the coronavirus.
The U.S. has been scrambling to get testing for the coronavirus up to speed.

A molecular biologist explains who should get tested, how the tests work and what the US government is doing to make tests available during a rapidly changing crisis.
Artist impression of neurons communicating in the brain.
A new technology has enabled neuroscientists to examine the chemistry of individual brain cells. The finding reveal how genes are regulated differently in brain cells of people with autism compared to neurotypical people.
Like the day’s newspaper, the brain has a temporary way to keep track of events.
How do brains convert experiences into memories? New research explores the chain of events by focusing on what genes shift into gear when neurons are firing.
