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.
With deepfake audio, that familiar voice on the other end of the line might not even be human let alone the person you think it is.

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.
Swimming underwater reduces drag so much there are rules against doing it for too long. But the best swimmers make the most of what’s allowed.
Opening all windows, or one front and one rear window, increases the amount of airflow in the car, reducing the risk of airborne transmission.

Fluid mechanics can be applied to the transport of respiratory diseases such as COVID-19.
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.

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?
With no identifiable body parts, it’s hard to know how these fossilized creatures lived. A new approach models how the ocean’s water would interact with their unique shapes – hinting at their lifestyle.
Defecation duration is surprisingly similar throughout the mammal world.

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.

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.
Filter-feeding fish have had 150 million years to improve filtration.

Even the best engineered filters get clogged eventually. Fish mouths have evolved structures that create unique fluid dynamics patterns that solve that problem.

The way sea lions swim is unique among fish and marine mammals. Their technique provides a biomechanical model to design agile underwater vehicles… but first we have to figure out how they do it.
Dr Andrew Stephenson and Dr Anthony Jacko examine the longest running laboratory experiment in the world.
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…
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…
