Stronger-than-binary correlations experimentally demonstrated for the first time

Quantum Physics News - Mon, 05/21/2018 - 09:30
For the first time, physicists have experimentally demonstrated ternary—rather than binary—quantum correlations between entangled objects. The results show that the quantum measurement process cannot be described as a binary process (having two possible outcomes), but rather stronger-than-binary ternary measurements (which have three possible outcomes) should be considered in order to fully understand how the quantum measurement process works.

Led a privileged working life? Then you're likely to have a pretty good third age

Social Sciences News - Mon, 05/21/2018 - 08:49
A new language is emerging to describe those who would have traditionally been called retired but are increasingly engaging in other forms of activity in later life. New terms for this phase of life include the third age, the encore stage and unretirement. But while some commentators predict a rosy picture of new found freedoms, others focus on problems caused by financial difficulties.

Disenfranchisement study impacts new voting rights laws

Social Sciences News - Mon, 05/21/2018 - 08:10
In March of this year, Washington State Governor Jay Inslee signed the Washington Voting Rights Act into law. The state's Voting Rights Act says that a jurisdiction is in violation of the law "…where there is a significant risk members of a protected class do not have an equal opportunity to elect candidates of choice as a result of dilution or abridgement of their rights."

Diamond 'spin-off' tech could lead to low-cost medical imaging and drug discovery tools

It may sound contradictory, but diamonds are the key to a new technique that could provide a very-low-cost alternative to multimillion-dollar medical imaging and drug-discovery devices.

Growing wealth gap between families with children and seniors

The wealth gap between households of seniors and those with children has ballooned since 1989, a new study finds.

NBA stars on losing teams follow fewer teammates on social media

NBA stars on winning teams are more likely to follow teammates on Twitter than their high-status counterparts on bad teams are, according to a new study by the University of Cincinnati.

Magnonic interferometer paves way toward energy-efficient information processing devices

General Physics - Fri, 05/18/2018 - 11:10
Researchers have designed an interferometer that works with magnetic quasiparticles called magnons, rather than photons as in conventional interferometers. Although magnon signals have discrete phases that normally cannot be changed continuously, the magnonic interferometer can generate a continuous change of the magnon signal. In the future, this ability could be used to design magnonic integrated circuits and other magnonic devices that overcome some of the limitations facing their electronic counterparts.

Robotic assembly of the world's smallest house—even a mite doesn't fit through the door

General Physics - Fri, 05/18/2018 - 10:23
A French nanorobotics team from the Femto-ST Institute in Besançon, France, assembled a new microrobotics system that pushes forward the frontiers of optical nanotechnologies. Combining several existing technologies, the μRobotex nanofactory builds microstructures in a large vacuum chamber and fixes components onto optical fiber tips with nanometer accuracy. The microhouse construction, reported in the Journal of Vacuum Science and Technology A, demonstrates how researchers can advance optical sensing technologies when they manipulate ion guns, electron beams and finely controlled robotic piloting.
