Fish, seaweed inspire slippery surfaces for ships

Long-distance cargo ships lose a significant amount of energy due to fluid friction. Looking to the drag reduction mechanisms employed by aquatic life can provide inspiration on how to improve efficiency.

Predicting delayed instabilities in viscoelastic solids

It is presently challenging to determine the stability of viscoelastic structures since seemingly stable conformations may gradually creep (plastic deformation of a material under stress as a function of time) until their ...

Floating a boat on the underside of a liquid

A team of researchers from Institut Langevin and Sorbonne Université has shown that it is possible to float boats on both the top and underside of a suspended fluid. In their paper published in the journal Nature, the group ...

Slippery superfluids push jets to breaking point

A unique type of helium that can flow without being affected by friction has helped a KAUST team better understand the transformation of rapidly moving liquids into tiny droplets.

Using a public restroom? Mask up!

Think you don't need to worry about COVID-19 while using a public restroom? A group of researchers from Yangzhou University in China recently reported that flushing public restroom toilets can release clouds of virus-laden ...

Humid air can extend lifetime of virus-laden aerosol droplets

The novel coronavirus that causes COVID-19 is thought to spread through natural respiratory activities, such as breathing, talking and coughing, but little is known about how the virus is transported through the air.

Using physics to improve root canal efficiency

Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature ...

Droplet spread from humans doesn't always follow airflow

The World Health Organization has warned that aerosol transmission of COVID-19 is being underestimated. If aerosol spread is confirmed to be significant, as suspected, we will need to reconsider guidelines on social distancing, ...

How to get rid of the coffee-stain effect

The coffee-stain effect is a well-known effect in physics and daily life in which a dark-colored edge remains when a fluid containing particles evaporates. This is caused by an "avalanche" of particles moving to the outer ...

Flushing toilets create clouds of virus-containing particles

Researchers used a computer simulation to show how a flushing toilet can create a cloud of virus-containing aerosol droplets that is large and widespread and lasts long enough that the droplets could be breathed in by others.
