Robot Invented To Crawl Through Veins 99

Slatterz writes "Scientists from Israel's Technion University have unveiled a tiny robot, made using Micro-Electro-Mechanical Systems (MEMS) technology, purportedly able to crawl through a person's veins in order to diagnose and potentially treat artery blockage and cancer. The little robot — with a diameter of just one millimeter — has neither engine nor onboard controls, instead being propelled forward by a magnetic field wielded on it from outside the patient's body."

Researchers Develop Self-Cleaning Clothes 220

Ponca City, We Love You writes "Researchers at Monash University, in Australia, have found a process to coat natural fibers such as wool, silk, and hemp that will automatically remove food, grime, and even red-wine stains by coating their fibers with titanium dioxide nanocrystals, which break down food and dirt in sunlight. Titanium dioxide is a strong photocatalyst and in the presence of ultraviolet light and water vapor, it forms hydroxyl radicals, which oxidize, or decompose, organic matter. "These nanocrystals cannot decompose wool and are harmless to skin," says organic chemist and nanomaterials researcher Walid Daoud. Titanium dioxide can also destroy pathogens such as bacteria in the presence of sunlight by breaking down the cell walls of the microorganisms making self-cleaning fabrics especially useful in hospitals and other medical settings."
