Instant-start computers possible with new breakthrough

If data could instead be encoded without current it would require much less energy, and make things like low-power, instant-on computing a ubiquitous reality. Researchers have made a breakthrough in that direction with a room-temperature magnetoelectric memory device. Equivalent to one computer bit, it exhibits the holy grail of next-generation nonvolatile memory: magnetic switchability, in two steps, with nothing but an electric field.

Ultrafast imaging of complex systems in 3-D at near atomic resolution nears

It is becoming possible to image complex systems in 3-D with near-atomic resolution on ultrafast timescales using extremely intense X-ray free-electron laser pulses. One important step toward ultrafast imaging of samples with a single X-ray shot is understanding the interaction of extremely brilliant and intense X-ray pulses with the sample, including ionization rates.
