Genetic modification shows promise for preventing hereditary hearing loss | Science Codex

Philadelphia, PA, November 6, 2015 – A mitochondrial defect is responsible for a type of human hereditary deafness that worsens over time and can lead to profound hearing loss. Using a genetically-modified mice model with a mitochondrial dysfunction that results in a similar premature hearing loss, researchers showed that precise genetic reduction of an enzyme, AMP kinase (AMPK), can rescue the hearing loss. Their results are reported in the American Journal of Pathology.

Taurid Meteor Shower Peaks Nov. 5 to 12: How To Watch : SCIENCE : Tech Times

Taurid Meteors or Halloween Fireballs are expected to have their peak appearance on Nov. 5 through Nov. 12. Spectators are advised to watch out for this bright meteor shower between midnight and dawn when the skies are darker and the constellation Taurus is high in the sky.

Longer-lasting, fast-charging battery could displace lithium-ion | PCWorld

A battery that can hold five times or more energy capacity than existing lithium-ion batteries could be in users’ hands as early as next year.

Prieto Battery, a startup, has developed a 3D solid-state battery structure based on new materials that can hold more lithium ions than current batteries. The new battery will also be less flammable, charge faster and shaped to fit into wearables and PCs as well as larger products like solar panels, said Amy Prieto, founder of Prieto Battery.

The battery has been researched for years, and Prieto Battery received an undisclosed amount of funding earlier this week from Intel Capital to help commercialize the technology. Prieto is working with Intel to develop a battery that could reach wearables and computing devices by 2017.

The startup, however, is also talking to an unnamed partner that could result in the release of batteries based on Prieto’s design starting as early as next year. Amy Prieto’s long-term dream is to make cheap and stable batteries for solar and wind farms.

The Prieto battery is a complete redesign of conventional lithium-ion batteries, which are based on a 2D structure. The structure of the Prieto battery can be implemented in existing manufacturing processes, and the company’s goal is to license the technology to battery makers.

Current batteries have electrodes—a cathode and an anode—with liquid electrolytes that allow charged lithium ions to move around. During a charge, lithium ions move from the cathode to the anode for storage. During a discharge, the lithium ions move from anode to cathode and out to the device using the battery.

Existing batteries can take a long time to charge, Prieto said. The Prieto battery eliminates the liquid electrolytes and has cathodes and anodes that are interlocked, which helps increase the density of lithium ions and speed up battery charge times. The anodes—which are made of copper substrates—provide more density than the graphite anode used in existing lithium-ion batteries.

Research to produce longer-lasting batteries has been going on for decades. While some batteries made of chemicals like silver-zinc have more storage capacity, lithium-ion batteries are backed by large manufacturers like Sony and Panasonic as they are cheaper to produce.

Prieto believes batteries based on its chemistry have a good chance of succeeding as they can be dropped into existing manufacturing and packaging processes. The goal is now to convince battery makers that its technology is better than what is currently available.

Intel’s backing is a big step ahead to commercialize the battery technology. The chip maker has manufacturing expertise and could provide access to computing and mobile devices to test the battery.

World’s Largest Rooftop Dual-Axis Solar Power Station Coming to Taiwan | AltEnergyMag

HSINCHU, Nov 4, 2015 – The world’s largest rooftop dual-axis solar power station is currently under construction on a food facility in Pingtung County of Taiwan. This is an 840-kW project which utilizes BIG SUN iPV solar trackers (dual-axis) to maximize energy output and be able to resist extreme weather conditions such as typhoons in Taiwan. Topper Sun, a subsidiary of BIG SUN Group, serves as the EPC of this project for Chailease Finance Co. (CFC). By the end of year 2015, this site will be installed completely.
