Physicist develops battery using new source of energy

Researchers at the University of Miami and at the Universities of Tokyo and Tohoku, Japan, have been able to prove the existence of a "spin battery," a battery that is "charged" by applying a large magnetic field to nano-magnets ...

Observing mammalian cells with superfast soft X-rays

Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or ...

Holographic message encoded in simple plastic

There are many ways to store data—digitally, on a hard disk, or using analog storage technology, for example as a hologram. In most cases, it is technically quite complicated to create a hologram: High-precision laser technology ...

DNA microcapsules: Scaling up the future of data storage

Storing data in DNA sounds like science fiction, yet it lies in the near future. Professor Tom de Greef expects the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones ...
