Randomness rules in turbulent flows

It seems perfectly natural to expect that two motorists who depart from the same location and follow the same directions will end up at the same destination. But according to a Johns Hopkins University mathematical physicist, ...

Using light to build nanoparticles into superstructures

Scientists in the Center for Nanoscale Materials and Argonne's Biosciences Division have demonstrated a remarkably simple, elegant, and cost-effective way of assembling nanoparticles into larger structures of any desired ...

Smashing fluids... the physics of flow

(PhysOrg.com) -- Hit it hard and it will fracture like a solid... but tilt it slowly and it will flow like a fluid. This is the intriguing property of a type of ‘complex fluid’ which has revealed ‘new physics’ ...

Whale-inspired ocean turbine blades

Interest in developing alternative energy sources is driving the consideration of a promising technology that uses underwater turbines to convert ocean tidal flow energy into electricity.

Secrets of sharks' success

New research from the University of South Florida suggests that one of the evolutionary secrets of the shark's success hides in one of its tiniest traits -- flexible scales on the bodies of these peerless predators that make ...

Swimming microorganisms stir things up

Two separate research groups are reporting groundbreaking measurements of the fluid flow that surrounds freely swimming microorganisms. Experiments involving two common types of microbes reveal the ways that one creature's ...

Supercomputing on a cell phone

Many engineering disciplines rely on supercomputers to simulate complicated physical phenomena — how cracks form in building materials, for instance, or fluids flow through irregular channels. Now, researchers in MIT’s ...

Bladeless wind turbine inspired by Tesla

(PhysOrg.com) -- A bladeless wind turbine whose only rotating component is a turbine/driveshaft could generate power at a cost comparable to coal-fired power plants, according to its developers at Solar Aero. The New Hampshire-based ...

Radical research changes lab-on-a-chip design

(PhysOrg.com) -- A University of Alberta mechanical engineering professor has developed a new model that could revolutionize the design of hand-held devices that provide reliable, nearly instant medical or environmental tests.

Solving Teapot Effect

(PhysOrg.com) -- A team of scientists from France have worked out why teapots dribble at low flow rates, and how to stop them. The effect is called the "teapot effect", and solving it could finally put an end to tea stains ...
