COVID-19 virus survives on surfaces within thin film

How does the COVID-19 virus manage to survive on surfaces? To find out, researchers in India are exploring the drying times of thin liquid films that persist on surfaces after most respiratory droplets evaporate.

Understanding dangerous droplet dynamics

Researchers who study the physics of fluids are learning why certain situations increase the risk that droplets will transmit diseases like COVID-19.

Tracing the flow of cerebrospinal fluid

Swelling is one of the most dangerous and immediate consequences of a brain injury or stroke. Doctors have long known about the dangers of swelling, which has traditionally been blamed on ruptured blood vessels. New research ...

Studies explore fluids in pancakes, beer, and the kitchen sink

Mechanical engineer Roberto Zenit spent the summer of 2019 trying to solve a problem that now plagues science departments around the world: How can hands-on fluid dynamics experiments, usually carried out in well-stocked ...

Social bacteria build shelters using the physics of fingerprints

Forest-dwelling bacteria known for forming slimy swarms that prey on other microbes can also cooperate to construct mushroom-like survival shelters known as fruiting bodies when food is scarce. Now a team at Princeton University ...

Oil droplet predators chase oil droplet prey

Oil droplets can be made to act like predators, chasing down other droplets that flee like prey. The behavior, which is controlled by chemical signaling produced by the droplets, mimics behavior seen among living organisms ...

Tracking flight trajectory of evaporating cough droplets

The ongoing COVID-19 pandemic has led many researchers to study airborne droplet transmission in different conditions and environments. The latest studies are starting to incorporate important aspects of fluid physics to ...

How everyday speech could transmit viral droplets

It is well known that an individual infected with the coronavirus can spread it to others through respiratory droplets projected by violent expiratory events like coughing and sneezing.
