Hidden turbulence discovered in polymer fluids

Turbulence, the chaotic, irregular motion that causes the bumpiness we sometimes experience on an airplane, has intrigued scientists for centuries. At the Okinawa Institute of Science and Technology (OIST), researchers are ...

Bumpy skies: How climate change increases air turbulence

The seatbelt sign pings on, trays rattle, drinks slosh in their glasses. For many fliers, air turbulence can be an unnerving experience—and in a world warming under the effects of climate change, it is only set to worsen, ...

Elegant theory predicts the chaos created by bubbles

A team of international researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Johns Hopkins University and Duke University has discovered that a century-old theory describing turbulence in fluids also applies ...

Tying light from lasers into stable 'optical knots'

Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or frustrate your attempts at hanging holiday decorations. A beam of light doesn't sound like a material ...
