Solid-state harmonics beyond the atomic limit

Strong-field laser excitation of solids can produce extremely nonlinear electronic and optical behaviour. As recently demonstrated, this includes the generation of high harmonics extending into the vacuum-ultraviolet and extreme-ultraviolet regions of the electromagnetic spectrum. High harmonic generation is shown to occur fundamentally differently in solids and in dilute atomic gases. How the microscopic mechanisms in the solid and the gas differ remains a topic...

Star Trek Beyond trailer gives us a good look at our new bad guy

Daddy issues < badass motorcycles in the new Star Trek Beyond trailer.

 The second Star Trek Beyond trailer dropped this weekend, and it gives us a much better sense of what our heroes will be dealing with in this flick. For those who haven't been paying attention, the premise of the new movie is pretty simple: New...

Meet NCAM, the researchers helping NASA go “to the Moon, to Mars, and beyond”

(video link)

MICHOUD, La.—Obviously, NASA's novel plans for its Space Launch System (SLS) and the Orion capsule require state of the art tools and engineering. But all those strategies, machines, and flight hardware don't appear out of thin air. While much of NASA's work is built on the shoulders of giants so to speak, they also find partners to continuously perform essential research and...

Space science: Cosmic rays beyond the knees

The development of a radio technique for detecting cosmic rays casts fresh light on the origins of some of these accelerated particles, and suggests that they might have travelled much farther than was previously thought. See Letter p.70

Crystallography: Resolution beyond the diffraction limit

A method has been devised that extends the resolution of X-ray crystal structures beyond the diffraction limit. This might help to improve the visualization of structures of proteins that form 'poorly diffracting' crystals. See Letter p.202
