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…

Gas vs. electric? Fuel choice affects efforts to achieve low-energy and low-impact homes

NIST’s Net Zero Energy Residential Test Facility in Gaithersburg, Maryland, provided measurements for a NIST analysis of the environmental impacts of gas and electric HVAC systems in energy-efficient Maryland homes. Credit: Beamie Young/NIST If you want to make your home as energy-efficient and green as possible, should you use gas or electric for your heating and cooling needs? Gas is the more eco-friendly option—for now—for an energy-efficient home in Maryland. That’s the conclusion of a new economic study by the National…

Why are gels elastic? New research shows how clustered particles determine elasticity of some gels — ScienceDaily

From the toothpaste you squeeze on your brush first thing in the morning to the yogurt you slurp down to the fabric softener that keeps your pajamas cozy and soft, gels are ubiquitous in consumer products, foods, and in industrial applications, too. However, until now, scientists have been unable to explain the microscopic structures within gels that impart their elasticity, or springiness, nor how those structures form. A team of scientists from the University of Delaware, Massachusetts Institute of Technology,…

College opens door for second annual Research Day showcase

Each year, Mizzou Engineering opens its doors to showcase the great work going on in its labs — work that has tremendous benefit and impact locally and globally. The second annual Research Day covered a lot of ground. The day concluded with a recognition of the Dean’s Council for Research Excellence and Dean’s Council of…

An exceptional strategy when winter comes — ScienceDaily

When winter comes, populations of red-neck phalarope from the Western Palearctic migrate to two different destinations -the Pacific Ocean or the Arabian Sea- following an exceptional migratory divide strategy which has never been described in this geographical area. A part of these bird populations -which breed in Greenland, Island and the British Islands- cross more than 10,000 kilometres to reach the Pacific Ocean, while populations in Scandinavia and Russia go to the Arabian Sea in the Indian Ocean, more than…

Microscopic and molecular evidence at paleolithic hearth sites helps uncover Neanderthal mobility habits — ScienceDaily

Ancient fire remains provide evidence of Neanderthal group mobility and settlement patterns and indicate specific occupation episodes, according to a new study published in PLOS ONE on April 24, 2019 by Lucia Leierer and colleagues from Universidad de La Laguna, Spain. Most paleolithic household activities are thought to have taken place around hearths or fires. The author of the present study chose to examine the Middle Paleolithic site El Salt in Spain, which contains eleven well-preserved and overlapping open-air hearth…
