Scientists design new grid batteries for renewable energy — ScienceDaily

How do you store renewable energy so it’s there when you need it, even when the sun isn’t shining or the wind isn’t blowing? Giant batteries designed for the electrical grid — called flow batteries, which store electricity in tanks of liquid electrolyte — could be the answer, but so far utilities have yet to find a cost-effective battery that can reliably power thousands of homes throughout a lifecycle of 10 to 20 years. Now, a battery membrane technology developed…

Ice on lunar south pole may have more than one source — ScienceDaily

The discovery of ice deposits in craters scattered across the Moon’s south pole has helped to renew interest in exploring the lunar surface, but no one is sure exactly when or how that ice got there. A new study published in the journal Icarus suggests that while a majority of those deposits are likely billions of years old, some may be much more recent. Ariel Deutsch, a graduate student in Brown University’s Department of Earth, Environmental and Planetary Sciences and…

Nobel Prize in Chemistry 2019: Lithium-ion batteries — ScienceDaily

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry 2019 to John B. Goodenough, of The University of Texas at Austin, USA, M. Stanley Whittingham, of Binghamton University, State University of New York, USA, and Akira Yoshino of Asahi Kasei Corporation, Tokyo, Japan, and Meijo University, Nagoya, Japan “for the development of lithium-ion batteries.” They created a rechargeable world The Nobel Prize in Chemistry 2019 rewards the development of the lithium-ion battery. This lightweight,…

Research compared effects of fresh and thermally processed oil — ScienceDaily

Foods fried in vegetable oil are popular worldwide, but research about the health effects of this cooking technique has been largely inconclusive and focused on healthy people. For the first time, UMass Amherst food scientists set out to examine the impact of frying oil consumption on inflammatory bowel disease (IBD) and colon cancer, using animal models. In their paper published Aug. 23 in Cancer Prevention Research, lead author and Ph.D. student Jianan Zhang, associate professor Guodong Zhang, and professor and…

Antineutrino detection could help remotely monitor nuclear reactors — ScienceDaily

Technology to measure the flow of subatomic particles known as antineutrinos from nuclear reactors could allow continuous remote monitoring designed to detect fueling changes that might indicate the diversion of nuclear materials. The monitoring could be done from outside the reactor vessel, and the technology may be sensitive enough to detect substitution of a single fuel assembly. The technique, which could be used with existing pressurized water reactors as well as future designs expected to require less frequent refueling, could…

Ludwig v0.2 Adds New Features and Other Improvements to its Deep Learning Toolbox

Uber released Ludwig, our open source, code-free deep learning toolbox, in February 2019, introducing the world to one of the easiest ways to get started building machine learning models. The simplicity and the declarative nature of Ludwig’s model definition files allows machine learning beginners to be productive very quickly, while its flexibility and extensibility enables even machine learning experts to use it for new tasks with custom models. Over the course of the last five months, a great community gathered…

Data offer new clues about why stars explode — ScienceDaily

When NASA’s Transiting Exoplanet Survey Satellite launched into space in April 2018, it did so with a specific goal: to search the universe for new planets. But in recently published research, a team of astronomers at The Ohio State University showed that the survey, nicknamed TESS, could also be used to monitor a particular type of supernova, giving scientists more clues about what causes white dwarf stars to explode — and about the elements those explosions leave behind. “We have…

OIL+VCache: File abstraction for distributed systems

For years, developers have open()ed a file, write()n to it, then read() from it on a local filesystem. In distributed systems, however, these actions involve multiple processes across different hosts at different places in the network. Each of these hosts — or the network itself — could fail independently and unexpectedly. How should a storage system react, if at all, to such failures? To allow developers to answer these questions, we created an output-input language (OIL), which has a unified…

Brunel fine-tunes next-generation digital engine

Credit: Brunel University London Brunel University London is the first UK university to start researching car engines of the future using new single cylinder intelligent valve technology. The electronically controlled system will supercharge engine development, helping car companies meet new emissions regulations and cut costs. Brunel’s Centre for Advanced Powertrain and Fuels (CAPF) is testing Camcon Auto’s digital valves for their vast potential and precision control. “We are very excited to collaborate with Camcon Auto in exploring and demonstrating the…

New technologies are gearing up to find fugitive methane leaks

A fixed-wing UAV screening system being launched from a catapult. Credit: The Conversation A suite of new technologies may soon be patrolling for fugitive —invisible but harmful —natural gas leaks from the oil and gas sector. Our recent study suggests that drones, aircraft, trucks, fixed sensors and even satellites may be poised to help find gas leaks quickly, preventing damage to the environment and human health. To date, hunting for leaks has been restricted to using a few handheld sensors.…
