Making Light Work of Quantum Computing

Light may be the missing ingredient in making usable quantum silicon computer chips, according to an international study featuring a University of Queensland researcher. The team has engineered a silicon chip that can guide photons along optical tracks, encoding and processing quantum-bits of information – ‘qubits’.

Professor Timothy Ralph from UQ’s Centre for Quantum Computation and Communication Technology said that the use of photons in this way could increase the number and types of tasks that computers can help us with...

Ice Confirmed at the Moon’s Poles

The image shows the distribution of surface ice at the Moon’s south pole (left) and north pole (right), detected by NASA’s Moon Mineralogy Mapper instrument. Blue represents the ice locations, plotted over an image of the lunar surface, where the gray scale corresponds to surface temperature (darker representing colder areas and lighter shades indicating warmer zones). The ice is concentrated at the darkest and coldest locations, in the shadows of craters. This is the first time scientists have directly observed definitive evidence of water ice on the Moon’s surface.

New Genetic Regulators of Regeneration identified

Comparative model of lncRNA-regulation of heart regeneration. Known and novel zebrafish lncRNAs adjacent or antisense to protein-coding genes (top) were connected to a set of previously characterized genes required for heart regeneration in the zebrafish (bottom). Gene regulatory and/or protein–protein interactions from Ingenuity Pathways Analysis were used to find a minimal set of homologous genes that connect the adjacent/antisense genes to the regeneration genes.

Toward Fast-Charging Solid-State Batteries

Toward #Fast-#Charging #Solid-State #Batteries There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire.

Test set-up for the solid-state battery: the battery of the size of a button cell is located in the middle of the acrylic glass casing, which ensures permanent contact with the battery.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Scientists have now introduced a new concept that allows currents up to 10X greater during charging and discharging than previously described in the literature.

The low current is considered one of the biggest hurdles in the development of solid-state batteries...
