Stabilizing molecule could pave way for lithium-air fuel cell

Science Daily - Wed, 26/04/2017 - 7:38pm
Lithium-oxygen fuel cells boast energy density levels comparable to fossil fuels and are thus seen as a promising candidate for future transportation-related energy needs. Several roadblocks stand in the way of realizing that vision. An engineering lab has focused on one of those roadblocks -- the loss of battery power, also known as capacity fade.

Genes that help trout find their way home

Science Daily - Wed, 26/04/2017 - 7:38pm
In the spring when water temperatures start to rise, rainbow trout that have spent several years at sea traveling hundreds of miles from home manage, without maps or GPS, to find their way back to the rivers and streams where they were born for spawning. Researchers have identified genes that enable the fish to perform this extraordinary homing feat with help from Earth's magnetic field.

GE Fixing Bug in Software After Warning About Power Grid Hacks

Slashdot - Wed, 26/04/2017 - 7:20pm
General Electric said on Wednesday it is fixing a bug in software used to control the flow of electricity in a utility's power systems after researchers found that hackers could shut down parts of an electric grid. From a report: The vulnerability could enable attackers to gain remote control of GE protection relays, enabling them to "disconnect sectors of the power grid at will," according to an abstract posted late last week on the Black Hat security conference website. Protection relays are circuit breakers that utilities program to open and halt power transmission when dangerous conditions surface.

Adidas Creates Trainers Made From Plastic Ocean Debris in Bid To End Pollution

Slashdot - Wed, 26/04/2017 - 6:40pm
Adidas is building on its previous commitment to turn plastic pollution into high-performance products. Next month, the German sportswear will begin selling three new editions of its popular UltraBoost shoe, all made from plastic debris found in the ocean. From a report: Helping to achieve its goal of creating one million pairs of the Ultra Boost style, Parley for the Oceans will produce trainers made from recycled ocean waste. Made up of 11 reused plastic bottles in each pair, the Ultra Boost' laces, lining and sock lining covers will be made of other recycled products, making for an environmentally-friendly high-performance product.

Seeing is believing: Diamond quantum sensor reveals current flows in next-gen materials

Science Daily - Wed, 26/04/2017 - 6:17pm
In a world-first, researchers have imaged electrons moving in graphene using a quantum probe found only in diamonds. The technique could be used to understand electron behavior and allow researchers to improve the reliability and performance of existing and emerging technologies. These images could reveal the microscopic behavior of currents in quantum computing devices, graphene and other 2-D materials, and be used to develop next generation electronics, energy storage (batteries), flexible displays and bio-chemical sensors.
