The US president has reignited controversy over the use of malaria drugs to guard against COVID-19. But there is little reliable evidence so far that this tactic is safe or effective.
Bats are key pollinators and seed-spreaders, and keep pests away.
Bats get a lot of negative press, but they also make positive contributions to the environment and to our lives.
Immune cells release proteins called cytokines which alert the rest of the immune system that a virus is present.
We blame the coronavirus for the thousands of deaths, but it is actually a hyperactive immune reaction that is the cause of death. An immunologist explains.
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.
The SARS-CoV-2 coronavirus is currently detected using invasive nasal swabs. But the virus is also present in saliva, potentially paving the way for cheaper, safer tests that people could do at home.
The US and its allies are demanding answers over how COVID-19 became a pandemic. But instead of pointing fingers at China, the inquiry should focus on scientific clues to help us thwart future disasters.
No matter the details of the plot, conspiracy theories follow common patterns of thought.

Recommendations around mask usage are confusing. The science isn't. Evidence shows that masks are extremely effective to slow the coronavirus and may be the best tool available right now to fight it.
Nearly two million antibody tests imported into Australia can't be used to diagnose COVID-19. But it's difficult to make an antibody test that is specific and sensitive enough.

Feeling desperate for a hug? You're not alone. Research suggests positive physical touch benefits our mental health.
The Egyptian pipistrelle bat is one of seven bat species associated with spreading the coronavirus Middle East Respiratory Syndrome.
Bats have been the reservoir for recent disease outbreaks, including SARS and the current COVID-19 pandemic. But it's human activity that allows the virus to cross over.
A molecule responsible for lowering our blood pressure also helps coronavirus get into our cells and replicate. And it occurs more in men than in women.

Early reports by the National Health Laboratory Service indicated that it had the capacity to do 30,000 tests a day. But capability to do so has not materialised.
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.
A vaccine historically used to prevent tuberculosis is now among the contenders for a COVID-19 vaccine. So what is the BCG vaccine and why might it work against coronavirus?
Sexually active men should consider wearing condoms during the pandemic.
