Fluid mechanics suggests alternative to quantum orthodoxy
The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum ...
Deceptive-looking vortex line in superfluid led to twice-mistaken identity
(Phys.org) —So long, solitons: University of Chicago physicists have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence ...
Tiny scallop-like robotic swimmers could deliver drugs to treat diseases
Researchers see Kelvin wave on quantum 'tornado' for first time
A spinning tornado of very cold liquid helium obeys the laws of quantum mechanics. Sometimes, two quantum tornadoes flex into curved lines, cross over and form an X, swap ends, and then retract—a process ...

Study tests theory that life originated at deep sea vents
One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about ...
40-year-old prediction confirmed: First direct proof of Hofstadter butterfly fractal observed in moire superlattices
A team of researchers from Columbia University, City University of New York, the University of Central Florida (UCF), and Tohoku University and the National Institute for Materials Science in Japan, have ...
Building a digital life form: OpenWorm, Open Source
How lapping canine tongues create columns of liquid, allowing them to gulp down water
If you've ever watched a dog drink water, you know that it can be a sloshy, spilly, splashy affair—in other words, adorable.
Researchers explain emergence of bacterial vortex
When a bunch of B. subtilis bacteria are confined within a droplet of water, a very strange thing happens. The chaotic motion of all those individual swimmers spontaneously organizes into a swirling vortex ...
Wet computer server could cut internet waste
A revolutionary liquid-cooled computer server that could slash the carbon footprint of the internet is being tested at the University of Leeds.
Watching fluid flow at nanometer scales: Researchers find that tiny nanowires can lift liquids as effectively as tubes
Imagine if you could drink a glass of water just by inserting a solid wire into it and sucking on it as though it were a soda straw. It turns out that if you were tiny enough, that method would work just fine—and wouldn't ...
New theory points to 'zombie vortices' as key step in star formation
(Phys.org) —A new theory by fluid dynamics experts at the University of California, Berkeley, shows how "zombie vortices" help lead to the birth of a new star.
