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.
Mathematicians make a splash with new theory that could lead to breakthroughs in 3D printing, climate science and forensics.
Gotcha, five times faster than the blink of an eye.

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.
A juvenile male black-throated mango hummingbird (
Anthracothorax nigricollis) extending his tongue after drinking nectar.
By filming these ultra-speedy feeders at transparent fake flowers, researchers finally figured out how hummingbirds slurp up the nectar so fast.

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…
