Safety experts ill-equipped to handle nanotechnology in workplace

Zinc oxide would be the perfect sunscreen ingredient if the resulting product didn't look quite so silly. Thick, white and pasty, it was once seen mostly on lifeguards, surfers and others who needed serious sun protection.

Inside a cramped back room at Rushford Hypersonic, a start-up headquartered in southeastern Minnesota, sits a cube-like machine that throws a mean atomic fastball. At the push of a button, the reactor hurls atoms toward a ...

In a cluster of rather drab buildings overlooking the Charles River, researchers at the Massachusetts Institute of Technology are incubating a tiny technology that packs an enormous punch.

The Canadian government reportedly is planning to release in February the world's first national regulation requiring companies to detail their use of engineered nanomaterials, according to environmental officials. The information ...

Nanotechnology policy experts are urging that food additives that contain nanoscale materials be subject to new safety testing to ensure that their use does not pose unintended risks.

A team of materials scientists and toxicologists announced the formation of a new international research alliance to establish protocols for reproducible toxicological testing of nanomaterials in both cultured cells and animals. ...

Physicist Pawel Sikorski and his group are making beds of nails on a miniature scale – a plate covered in nano-needles designed to puncture individual cells.

(Phys.org) —Northwestern University researchers have developed a new method for delivering molecules into single, targeted cells through temporary holes in the cell surface. The technique could find applications ...

Cancers of all types become most deadly when they metastasize and spread tumors throughout the body. Once cancer has reached this stage, it becomes very difficult for doctors to locate and treat the numerous tumors that can ...

(Phys.org) —Grapefruits have long been known for their health benefits, and the subtropical fruit may revolutionize how medical therapies like anti-cancer drugs are delivered to specific tumor cells. University ...

Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Mayo Clinic researchers found out why, and determined how to make the nanoparticles effective ...

The miniaturization of electronics continues to create unprecedented capabilities in computer and communications applications, enabling handheld wireless devices with tremendous computing performance operating ...
