Sandia's Z machine receives funding aimed at fusion energy
A two-year, $3.8 million award has been received by Sandia National Laboratories and the University of Rochester's Laboratory for Laser Energetics (LLE) to hasten the day of low-cost, high-yield fusion reactions for energy purposes.

Ultrasonic fingerprint sensor may take smartphone security to new level
Fingerprint sensor technology currently used in smartphones like the iPhone 6 produces a two-dimensional image of a finger's surface, which can be spoofed fairly easily with a printed image of the fingerprint. A newly developed ultrasonic sensor eliminates that risk by imaging the ridges and valleys of the fingerprint's surface, and the tissue beneath, in three dimensions.

Researchers develop algorithm to help identify patient zero in an epidemic
(Phys.org)—A team of researchers affiliated with several institutions in Croatia has developed an algorithm that is able to help pinpoint the first person who became ill when an epidemic occurred. In their paper published in the journal Physical Review Letters, the team describes how they built their algorithm, how it was tested and how accurate they believe it is.

The quantum spin Hall effect is a fundamental property of light
In a paper that crystalizes knowledge from a variety of experiments and theoretical developments, scientists from the RIKEN Center for Emergent Matter Science in Japan have demonstrated that the quantum spin Hall effect—an effect known to take place in solid state physics—is also an intrinsic property of light.

Highly-precise comparison of mercury and strontium optical lattice clocks
Scientists have developed a mercury-based optical lattice clock and measured the mercury clock frequency using the same group's recently developed strontium-based optical lattice clock as a reference. The research group achieved a fractional frequency uncertainty, which is smaller than the realization of the current international standard definition of the second.
