A new way to identify stresses in complex fluids

Fluid dynamics researchers use many techniques to study turbulent flows like ocean currents, or the swirling atmosphere of other planets. Arezoo Adrekani's team has discovered that a mathematical construct used in these fields ...

New method simultaneously measures flow and oxygen

An international research team headed by the Max Planck Institute for Marine Microbiology in Bremen, Aarhus University and the Science for Life Lab in Uppsala has developed tiny particles that measure the oxygen concentration ...

Explaining a fastball's unexpected twist

An unexpected twist from a four-seam or a two-seam fastball can make the difference in a baseball team winning or losing the World Series. However, "some explanations regarding the different pitches are flat-out wrong," said ...

Shaken, and stirred: Scaling up bioreactors' fluid dynamics

Bioreactors are widely used to produce different therapeutics in the biopharmaceutical and regenerative medicine industries. Drug development relies on small multi-well plates shaken around an orbital diameter, while production-scale ...

Gazing into the flames of ionic winds

New 3-D visualizations that reveal how flames respond to electric fields could help improve combustion efficiency and reduce pollution.

Winging it: How do bats out-maneuver their prey?

Bats catch food 'on the wing' without touching the ground, but how do they do it? A new study by Per Henningsson at Lund University, Sweden is the first of its kind to analyse the aerodynamics of bats performing manoeuvers ...

Image: A laser-sharp view of blended wing body plane design

Engineers at NASA's Langley Research Center in Hampton, Virginia, used lasers inside the 14- by 22-Foot Subsonic Tunnel to map how air flows over a Boeing Blended Wing Body (BWB) model – a greener, quieter airplane design ...
