Smashing fluids: The physics of flow

The new findings will be highly useful to the manufacturing industry because the processing and dispensing of everyday products like toothpaste, cosmetics, pharmaceuticals and foodstuffs depends on an understanding of the physical properties and...

Chemicals’ study pinpoints threat to workers’ lungs

Tiny particles used in a range of everyday products from computers to shampoo can adversely affect the lungs in very different ways, a study has shown. Research by the University of Edinburgh suggests that industrial manufacturers using nanopartic...

Contact lenses that dispense prescription drugs

Eye diseases like glaucoma could one day be treated by pharmaceuticals delivered through contact lenses. Chemical engineers from the University of Florida say they've been able to make soft contact lenses containing tiny embedded particles that slowly release drugs directly where they're needed. The research was presented today at the 225th national meeting of the American Chemical Society, the world's largest scientific society, held this week in New Orleans.

Nanotech Decoys for Viruses

Using nanotechnology to stop HIV viruses from entering cells is the ultimate aim of a new project at the University of California, Davis. The researchers hope to create tiny particles that can interfere with the proteins that viruses such as HIV use to attach to cells.

Freeway living not for the weak of lung

Get a little distance from the matter.In case there was any doubt, researchers in --- where else? --- Los Angeles have determined that living near a freeway exposes you to a lot more pollution than if you lived further away. Specifically, a UCLA team found people who live, work or travel within 165 feet downwind of a major freeway or busy intersection are exposed to potentially hazardous particle concentrations up to 30 times greater than normal background levels.
