New model describes puffs, slugs and the role of randomness in transitional turbulence

Mention the word "turbulence" and you might conjure up images of bumpy flights, stormy weather, and choppy ocean or river currents. For many, turbulence is a fact of daily life, yet it is also one of the most poorly understood ...

Physicists capture the sound of a 'perfect' fluid

For some, the sound of a "perfect flow" might be the gentle lapping of a forest brook or perhaps the tinkling of water poured from a pitcher. For physicists, a perfect flow is more specific, referring to a fluid that flows ...

Hairy tongues help bats drink up

Animals have evolved all manner of adaptations to get the nutrients they need. For nectar-feeding bats, long snouts and tongues let them dip in and out of flowers while hovering in mid-air. To help the cause, their tongues ...

Switched-on Salmonella: Fluid forces guide disease traits of multidrug-resistant bacteria

Once inside the human body, infectious microbes like Salmonella face a fluid situation. They live in a watery world, surrounded by liquid continually flowing over and abrading their cell surfaces—a property known as fluid ...

How mouse embryos determine left from right

RIKEN biologists have discovered how tiny hairs in embryos detect flowing fluid, which ultimately leads to the left and right sides of the embryo developing differences. As well as resolving a long-standing debate, this finding ...
