Risky life-science projects need global governance. Unfortunately, current standards and practices are not up to the task.

These new antivirals are another way of managing COVID-19. But they’re not a panacea, and could even makes things worse.
Social scientists find that using geography-related names or racialized framing around the coronavirus in even one news story can trigger racist stereotypes and biases.
One of the consequences of the failure of developing countries like South Africa to authorise self-testing is that it is driving a thriving black market.
COVID-19 variants are the products of the evolution of the SARS-CoV-2 virus. They arise via mutations, but other forces also have roles to play in the generation and transmission of variants.
COVID-19 has taken away so much. An immunology researcher describes the good it may leave behind.
South Africa is still likely to experience periods of increased cases, smaller-scale outbreaks and even the development of new variants.
It’s easy to avoid common pitfalls when taking rapid antigen tests. Here are a few to watch out for.
A growing body of research shows that COVID-19 protocols should be extended to areas in which there is a human-animal interface such as zoos, wildlife sanctuaries and game farms.
Life-saving blood is needed for everything from treating cancers and chronic conditions to helping trauma victims. But blood donations have dropped to crisis levels during the pandemic.
Cases of the Omicron sub-variant BA.2 are now in Australia. While there’s no evidence it causes more severe disease than the original Omicron, early research suggests it’s more transmissible.
Endemic doesn’t mean we drop our guard, surrender to the virus or downgrade the threat the virus poses to individuals and the community.
Some of the omicron variant’s unique properties – such as its ability to spread rapidly while causing milder COVID-19 infections – could usher in a new phase of the pandemic.
None of our authors can see the future, but many do have expertise that offers insights about what’s reasonable to expect.
People are buzzing with questions about the omicron variant and whether it could help usher in herd immunity. A team of virologists deciphers the latest findings.
The health care system is hemorrhaging medical lab workers, in part because of COVID-19 infections and also because of burnout, low wages and better opportunities elsewhere.
Are economic drivers the reason for the reduced isolation period in the UK?
To discover your risk of catching coronavirus for any given situation, try our COVID-19 Aerosol Transmission Estimator.
Even with a variant like Omicron that may be more transmissible than earlier variants, vaccines remain the most effective tool for protection against COVID-19 and for ending the pandemic.
A nationwide genomic surveillance system analyzes positive COVID-19 tests to build a picture of which variants are spreading in the population.
