ata for only a fraction of a second. They note that William the Conqueror's Doomsday Book, written on vellum in 1086 AD, has survived 900 years. However, the medium used for a digital version of the book, encoded in 1986, failed within 20 years.

The researchers describe development of an experimental memory device consisting of an iron nanoparticle (1/50,000 the width of a human hair) enclosed in a hollow carbon nanotube. In the presence of electricity, the nanoparticle can be shuttled back and forth with great precision. This creates a programmable memory system that, like a silicon chip, can record digital information and play it back using conventional computer hardware. In lab and theoretical studies, the researchers showed that the device had a storage capacity as high as 1 terabyte per square inch (a trillion bits of information) and temperature-stability in excess of one billion years.

Long-forgotten research may yield new malaria treatments
Chemical & Engineering News

An unlikely friendship between a 94-year-old retired scientist and a biochemist at Rutgers University has lead to the revival of a World War II-era research program to develop new drugs against malaria, the deadly mosquito-borne disease that kills almost one million people annually, according to an article scheduled fo
