Conceptual picture of the new exotic quantum states that have been generated in Innsbruck. The generation of quantum entanglement in a string of 20 single atoms is shown. Entanglement between neighboring atom pairs (blue), atom triplets (pink), atom quadruplets (red) and quintuplets (yellow) was observed, before the system became too complex to characterize with existing techniques.

Largest entangled quantum register of individually controllable systems to date. A research team is now presenting the largest entangled quantum register of individually controllable systems to date, consisting of a total of 20 quantum bits. The physicists are pushing experimental and theoretical methods to the limits of what is currently possible.

Some of the new quantum t...

This artist’s concept illustrates Kepler-16b, the first planet known to orbit two stars – what’s called a circumbinary planet. The planet, which can be seen in the foreground, was discovered by NASA’s Kepler mission. New research from the University of Washington indicates that certain shot-period binary star systems eject circumbinary planets as a consequence of the host stars’ evolution.NASA/JPL-Caltech/T.

Planets orbiting “short-period” binary stars, or stars locked in close orbital embrace, can be ejected off into space as a consequence of their host stars’ evolution, according to new research from the University of Washington...

Mathew Boban, Graduate Student Research Assistant, Materials Science and Engineering, pours hexadecane oil onto a glass slide with a superomniphobic coating. The petroleum based, highly viscous lubricant slide easily off the slide, opening up applications like self-cleaning windows, ink jet printers and microfluidic devices.

In an advance that could grime-proof phone screens, countertops, camera lenses and countless other everyday items, a materials science researcher at the University of Michigan has demonstrated a smooth, durable, clear coating that swiftly sheds water, oils, alcohols and, yes, peanut butter.

Called “omniphobic” in materials science parlance, the new coating repels just about every known liquid...

Researchers at the University of Washington have designed a convenient and natural product that uses proteins to rebuild tooth enamel and treat dental cavities. The research finding was first published in ACS Biomaterials Science and Engineering. “Remineralization guided by peptides is a healthy alternative to current dental health care,” said Mehmet Sarikaya, professor of materials science and engineering and adjunct professor in the Department of Chemical Engineering and Department of Oral Health Sciences.

The new biogenic dental products can – in theory – rebuild teeth and cure cavities without today’s costly and uncomfortable treatments...
