Just as the invention of nonstick pans was a boon for chefs, a new type of nanoscale surface that bacteria can't stick to holds promise for applications in the food processing, medicine and even shipping industries.
Scientists developing a prototype optical quantum hard drive have improved storage time by a factor of over 100. The team's record storage time of six hours is a major step towards a secure worldwide data encryption network based on quantum information
The quantum dots in these displays also use materials and technologies - including engineered nanoparticles and the heavy metal cadmium - that have been a magnet for health and environmental concerns. Will the dazzling pictures this technology allow blind us to new health and environmental challenges, or do their benefits outweigh the potential risks?
