The earliest cells likely didn’t have membranes to separate and protect their components and chemistry away from a harsh surrounding environment. But they may have made do with rain.

Toilets eject aerosol droplets that may carry disease-causing pathogens. Learning about how these particles move could help reduce exposure in public restrooms.
The chemical reaction that forms essential biomolecules like proteins and DNA normally doesn’t occur in the presence of water. Microdroplets provide a unique environment that make it possible.
How well your mask works depends on how well it fits. Wearing two snug masks made of different materials offers 95% protection from exposure to aerosols that could contain the coronavirus.
Experts weigh in on whether they will sit and eat at a restaurant.
Epidemiologists reviewed 25 studies of cloth face masks. Here’s what they found out about how well they work, why they work, who they protect and why the mosquito and chain-link fence analogy is wrong.
Our video shows aerosol emissions from singing a simple scale. No wonder singing in a choir can be risky.
Many people in Victoria are opting to wear face shields instead of face masks. It’s allowed – but are they as effective at preventing the spread of COVID-19?
The more layers your mask has, the better, our new research confirms.
More than 200 scientists wrote to the World Health Organization, warning about aerosol transmission of the coronavirus.
Fluid mechanics can be applied to the transport of respiratory diseases such as COVID-19.
SARS-CoV-2 can be spread through the air. But just how much of a factor that is has been hard to determine. Recent evidence suggests it is common, posing problems as public places begin to reopen.
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.
Your body can be infected and fight off SARS-CoV-2 without your ever noticing.
The CDC is reconsidering its policy about the widespread public’s use of masks, as is the World Health Organization. Here are the facts about when it’s appropriate to wear a mask – and what kind.
