How cancer cells move and metastasize is influenced by the fluids surrounding them – understanding how tumors migrate can help stop their spread

Counterintuitively, cells move faster in thicker fluids. New research on breast cancer cells explains why, and reveals the role that fluid viscosity plays in metastasis.

Deepfake audio has a tell – researchers use fluid dynamics to spot artificial imposter voices

AI-generated voice-alikes can be indistinguishable from the real person’s speech to the human ear. A computer model that gives voice to the dinosaurs turns out to be a good way to tell the difference.
Measuring in at 10,159 miles (16,350 kilometers) in width (as of April 3, 2017) Jupiter’s Great Red Spot is 1.3 times as wide as Earth. NASA/JPL-Caltech/SwRI/MSSS/Christopher Go

Contrary to recent reports, Jupiter’s Great Red Spot is not in danger of disappearing

Little bits of Jupiter’s Great Red Spot seem to be flaking off. Is it a sign of the demise of this enigmatic red cloud, or just a consequence of atmospheric chaos we can’t see from above?

Physics of poo: Why it takes you and an elephant the same amount of time

New parenthood got our fluid dynamics experts thinking about what ends up in the diaper. They headed to the zoo and the lab to come up with a cohesive physics story for how defecation works.

The frog tongue is a high-speed adhesive

How do a frog’s tongue and saliva work together to be sticky enough to lift 1.4 times the animal’s body weight? Painstaking lab work found their spit switches between two distinct phases to nab prey.
Dr Andrew Stephenson and Dr Anthony Jacko examine the longest running laboratory experiment in the world.

Explainer: the pitch drop experiment

Something strange is happening within the world-famous pitch drop experiment with the latest drop forming much faster than the last couple of drops. There have been nine drops so far and all attention…

It’s no reverse microwave, but it is cool

How can you turn lukewarm lager to ice-cold beer in under a minute? A startup has developed a nifty gizmo which does just that, saving both energy and embarrassment at parties. Manufacturer Enviro-Cool…

The most efficient swimming stroke

The ‘deep-catch’ stroke, which pulls through water like a boat paddle, is the most efficient swimming stroke. High-precision…
