Using physics to improve root canal efficiency

Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature ...

'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 ...

New discovery in shear-thickening fluids such as detergents

What do paint, dishwasher detergent, ketchup and blood have in common? All are composed of particles suspended in a carrier liquid, flow when stirred or forced, but remain thick or even gel-like at rest.

Scientists discover rigid structure in centre of turbulence

Pioneering mathematical engineers have discovered for the first time a rigid structure which exists within the centre of turbulence, leading to hope that its chaotic movement could be controlled in the future.

Space Research May Help Explain Salmonella Illness

(PhysOrg.com) -- Salmonella bacteria research from two recent NASA space missions discovered key elements of the bacteria's disease-causing potential that hold promise for improving ways to fight food-borne infections on ...
