A Terabyte of Data on a Regular DVD? 200

Roland Piquepaille writes "This is the promise of the 3-D Optical Data Storage system developed at the University of Central Florida (UCF). This technology allows to record and store at least 1,000 GB of data on multiple layers of a single disc. The system uses lasers to compact large amounts of information onto a DVD and the process involves shooting two different wavelengths of light onto the recording surface. By using several layers, this technique will increase the storage capacity of a standard DVD to more than a terabyte.

Laser Turns All Metals Black 333

Roland Piquepaille writes "Researchers at the University of Rochester have found a way to change the properties of almost any metal by using a femtosecond laser pulse. This ultra-intense laser blast creates true 'black metal' from copper, gold or zinc by forming nanostructures at the surface of the metal. As these nanostructures capture radiation, the metals turn black. And as the process needs surprisingly low power, it could soon be used for a variety of applications, such as stealth planes, black jewels or car paintings. But read more for additional references and a picture of this femtosecond laser system."

The Physics of a Good Store Location 72

Roland Piquepaille writes, "In 'Atomic Physics Predicts Successful Store Location,' LiveScience reports that a French physicist has applied methods used to study atomic interactions for another task: to 'help business owners find the best places to locate their stores.' Pablo Jensen has used his method for the city of Lyon and is now developing software with the local Chamber of Commerce to help future business owners. Read more for additional references and maps of the city of Lyon showing for example the best locations to open a bakery, according to atomic physics." Jensen says that more research is needed to know if this method would work in other cities.

A Buckyegg Breaks Pentagon Rules 137

Roland Piquepaille writes "Chemists from Virginia and California have cooked a soup of fullerenes which produced an improbable buckyegg. The egg-shaped structure of their 'buckyballs' was a complete surprise for the researchers. In fact, they wanted to trap some atoms of terbium in a buckyball "to make compounds that could be both medically useful and well-tolerated in the body." And they obtained a buckyegg which both violates some chemistry laws and the FIFA soccer laws which were used until the last World Cup. Read more for additional references and a picture of this buckyegg carrying metal molecules."
