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.…

Mixing skin oil and ozone can produce a personal pollution cloud — ScienceDaily

When ozone and skin oils meet, the resulting reaction may help remove ozone from an indoor environment, but it can also produce a personal cloud of pollutants that affects indoor air quality, according to a team of researchers. In a computer model of indoor environments, the researchers show that a range of volatile and semi-volatile gases and substances are produced when ozone, a form of oxygen that can be toxic, reacts with skin oils carried by soiled clothes, a reaction…

Biggest such known formation; could signal resources worldwide — ScienceDaily

In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean. It appears to be the largest such formation yet found in the world. The aquifer stretches from the shore at least from Massachusetts to New Jersey, extending more or less continuously out about 50 miles to the edge of the continental shelf. If found on the…

Making flying actually sustainable

The new solar mini-refinery located on the roof of ETH’s Machine Laboratory building in Zurich can produce climate-neutral fuels for sustainable aviation in the future. Credit: Tricklabor / ETH Zurich CO2 -neutral synthetic fuels are technically feasible today and the best promise for decarbonizing aviation. The right policy instruments could turn promise into reality, writes Anthony Patt. Technologies are emerging that could make it possible to fly with renewable energy. The most important approach is using renewable energy to synthesize…

A new manufacturing process for aluminum alloys

PNNL’s ShAPE™ process combined with a unique aluminum alloy produced high-strength, high-ductility rods in one single process. Credit: Andrea Starr | Pacific Northwest National Laboratory An advanced manufacturing process to produce nano structured rods and tubes directly from high-performance aluminum alloy powder—in a single step—was recently demonstrated by researchers from the Pacific Northwest National Laboratory. Using a novel Solid Phase Processing approach, the research team eliminated several steps that are required during conventional extrusion processing of aluminum alloy powders, while…

Monthly average surpassed 414 ppm at NOAA’s Mauna Loa Observatory in Hawaii — ScienceDaily

Atmospheric carbon dioxide continued its rapid rise in 2019, with the average for May peaking at 414.7 parts per million (ppm) at NOAA’s Mauna Loa Atmospheric Baseline Observatory. The measurement is the highest seasonal peak recorded in 61 years of observations on top of Hawaii’s largest volcano and the seventh consecutive year of steep global increases in concentrations of carbon dioxide (CO2), according to data published today by NOAA and Scripps Institution of Oceanography. The 2019 peak value was 3.5…

Desalinating water in a greener and more economical way

Credit: Ecole Polytechnique Federale de Lausanne We know that excessive consumption, industrial activity and growth in the global population are some of the factors threatening access to drinking water for an increasing proportion of people around the world. According to UNESCO figures from 2012, almost 700 million people suffer from limited access to water—and that number could rise to 1.8 billion by 2025. Desalination and the treatment of industrial wastewater can produce large amounts of drinking water, and these methods…
