Tear gas should be banned, researchers find; here's why

The use of tear gas—particularly CS gas—as a riot control agent, cannot be reconciled with respect for fundamental human rights and should therefore be banned entirely in international law, the University of Toronto's ...

Dynamics of tears: A cure for dry eye could be a blink away

A treatment for dry eye—a burning, gritty condition that can impair vision and damage the cornea—could some day result from computer simulations that map the way tears move across the surface of the eye.

Physicists working to cure 'dry eye' disease

The eye is an exquisitely sensitive system with many aspects that remain somewhat of a mystery—both in the laboratory and in the clinic. A U.S.-based team of mathematicians and optometrists is working to change this by ...

Molecular tug-of-war could lead to new materials

Tug-of-war isn't just for play. In the chemistry world, the game could identify a Saran-wrap-like material that instantly heals microscopic tears in its own structure.
