Excerpt: An electrified highway is theoretically the most efficient way to eliminate truck emissions. But the political obstacles are daunting. [photo] Overhead wires providing electricity to this truck cover three miles of highway south of Frankfurt. The idea is to test the system through everyday use by real trucking companies....

Warmer, more crowded cities bring out the rats

By -
By Elizabeth Pennisi , Science.  Excerpt: Climate change  emerged as a driving factor behind urban rat swarms , the researchers report today in  Science Advances . As temperatures rise, they conclude, and people flock to urban areas and convert formerly “green” spaces into neighborhoods and shopping centers, they created a perfect storm for rat populations to explode. And the city that’s fared the worst over the past decade? Washington, D.C.....  Full article at https://www.science.org/content/article/warmer-more-crowded-cities-bring-out-rats .

New Lessons from Old Ice: How We Understand Past (and Future) Heating

By -
By Mariana Mastache-Maldonado , Eos/AGU.  Excerpt: Fragments of blue ice up to 6 million years old—the oldest ever found—offer key insights into Earth’s warming cycles. Researchers are using these ancient data to refine models of our future climate. ...In Antarctica...rare formations known as blue ice areas may offer a distinct look into that deep past. These areas, which make up barely 1% of the continent, form where strong winds strip away surface snow. ...The Allan Hills region, situated on the edge of the East Antarctic Ice Sheet.... Here researchers have discovered ice up to 6 million years old—the oldest yet found. Their  study  of the ice, published in  Proceedings of the National Academy of Sciences of the United States of America , revealed that parts of it formed during periods far warmer than today—times when sea levels were higher and open forests and grasslands covered much of the planet. ...studying the atmospheric remnants trapped in blue ice, the rese...

France hits hydrogen jackpot: World’s largest reserve valued $92 trillion found

By -
By Sujita Sinha , Interesting Engineering.  Excerpt: Scientists in France have made a groundbreaking discovery that could transform clean energy production. Beneath the soil of Folschviller, in the Moselle region, researchers have uncovered an astonishing 46 million tons of natural hydrogen ...providing a new source of carbon-free fuel. The discovery was made by scientists from the GeoRessources laboratory and the CNRS while they were searching for methane. Instead, at a depth of 4,101 feet (1,250 meters), they found an enormous deposit of white hydrogen. This form of  hydrogen  is naturally occurring and does not require industrial production, unlike green hydrogen, which is made using renewable energy, or gray hydrogen, which is derived from fossil fuels. To put this discovery into perspective, the newly found deposit represents more than half of the world’s annual gray hydrogen production—but without the environmental costs. If extracted efficiently, this resource coul...
