'Aneurysm Number' may help surgeons make treatment decisions

Aneurysms form as abnormal bulges or balloonings over an artery, and, if ruptured, can lead to serious health complications or even death. Some aneurysms can exist for a long time without rupturing, and the surgery involved ...

How our tissues manage mechanical stress

When running, breathing and moving, the body is continuously deforming. How do the tissues in the body deal with all these mechanical stresses? Publishing today in Nature Physics, researchers from Wageningen University & ...

Sculpting stable structures in pure liquids

Oscillating flow and light pulses can be used to create reconfigurable architecture in liquid crystals. Materials scientists can carefully engineer concerted microfluidic flows and localized optothermal fields to achieve ...

New geometric model improves predictions of fluid flow in rock

Deep beneath the Earth's surface, oil and groundwater percolate through gaps in rock and other geologic material. Hidden from sight, these critical resources pose a significant challenge for scientists seeking to evaluate ...

Variations in seafloor create freak ocean waves

Florida State University researchers have found that abrupt variations in the seafloor can cause dangerous ocean waves known as rogue or freak waves—waves so catastrophic that they were once thought to be the figments of ...

Revealing hidden information in sound waves

By essentially turning down the pitch of sound waves, University of Michigan engineering researchers have devised a way to unlock greater amounts of data from acoustic fields than ever before.

How stretchy fluids react to wavy surfaces

Viscoelastic fluids are everywhere, whether racing through your veins or through 1,300 kilometers of pipe in the Trans-Alaska Pipeline. Unlike Newtonian fluids, such as oil or water, viscoelastic fluids stretch like a sticky ...

Simulating hypersonic flow transitions from smooth to turbulent

To break out of Earth's lower orbit, hypersonic vehicles must reach speeds greater than Mach 5. At these hypersonic speeds, the air particles and gases that flow around the vehicle and interact with the surfaces generate ...
