Using a grant from the Solution's Journalism Network our journalists have spent months looking for answers to Utah's air pollution problem. OSLO, Norway — In the center of Oslo, a man-made cavern rests beneath a hulking stone castle. A winding tunnel leads underground to a large opening, eerily dark and cool, where metal bars block the path to a medieval prison. Inside, you’ll find something out of place for the 17th century: 86 electric cars and charging stations. Once an underground military bunker, the cavern is now a parking garage. City officials repurposed the fortress, which used to protect the city against war-hungry Swedes and Danes, to guard against a new threat: air pollution. On a clear … [Read more...] about Special report: Does Norway hold the key to Utah’s air pollution problem?
Why does salt make ice colder
Visit The Boston Globe Share on Twitter Share on Facebook Comment on this Scroll to top of page By Linda Rodriguez McRobbie June 30, 2018 The earliest recipe book devoted entirely to making ice cream was “L’Art de bien faire les glaces d’office,” published in 1768 by a mysterious Monsieur Emy. The illustration on the frontispiece depicts roughly how ice cream was made at the time: By industrious flocks of chubby, naked cherubs with tiny wings, while the Holy Trinity — God and Jesus, languidly reposing in the clouds and flanking a rather startled dove — look down from the heavens.That wasn’t exactly how it really went, but ice cream in 1768 might as well have been made by angels, so exciting and novel was the experience of eating it and so closely-guarded the process of making it.“If you knew how to make ices, you had a meal ticket for life, and you would lock the door of your confectionery so nobody knew how you did … [Read more...] about How ice cream made America
Will Robinson uses his chemistry knowledge to formulate an anti-ice plan in the first episode of "Lost in Space," but is the science sound? Phil Hornshaw, provided by Published 4:31 pm, Sunday, April 15, 2018 Image 1of/1 CaptionClose Image 1 of 1 ‘Lost in Space': Would Will Robinson’s Magnesium Idea Really Work to Melt Ice? 1 / 1 Back to Gallery (Note: This post contains spoilers for the first episode of Netflix’s “Lost in Space.”) Netflix’s reimagining of the classic 1960s sci-fi TV show “Lost in Space” has the Robinson family, marooned on a distant alien planet, encountering all kinds of dangerous hazards. One of the marks of the new series is its more realistic take on space travel, and some spiffy uses of science to solve those life-threatening space problems. The first episode of the show sees one such life-threatening space problem afflict the Robinsons, when they crash-land on an … [Read more...] about ‘Lost in Space’: Would Will Robinson’s Magnesium Idea Really Work to Melt Ice?
On Father's Day, I picked a fight with my dad.The argument was about homemade ice cream, and the fact that for all the rosy memories of us gathered around my father's grinding monstrosity of an ice cream machine, waiting for that first taste, the ice cream was lousy."I think my ice cream tasted pretty good," my dad said, fondly nostalgic."Ummmm," I answered.Then I told him: The homemade ice cream I'd had (made by him or me) just wasn't worth it.Soupy, overly sweet, icy, bland and dependent on a space-hogging appliance.My thinking goes, if homemade ice cream can't top the creamy texture and rich flavors found in any decent supermarket, why bother? Let's face it, even Haagen-Dazs vanilla bean is still unimpeachable."When I was a kid growing up," says Jeni Britton Bauer, creator of Jeni's Splendid Ice Creams, "we'd make ice cream, and I was always the kid who just wanted to go down to Haagen-Dazs."But a few years ago, after becoming a nationally recognized ice cream professional, Britton … [Read more...] about Homemade ice cream: Better by degrees
Salt water could be running down some slopes of Mars every spring, researchers suggest. Such a finding would suggest new directions to search for any life that still existed on the Red Planet. Clusters of dark, narrow lines that periodically emerge and lengthen on slopes in the warmer regions suggest briny water on Mars might still be flowing in a few rare places on the planet's surface. "This is water today, not in the past," study co-author Alfred McEwen, a planetary scientist at the University of Arizona, told SPACE.com. A great deal of evidence on the Martian surface suggests the planet was wet and perhaps capable of supporting life in the past. Although frozen water has been detected near the surface in many middle-to-high latitudes, there has been no definitive evidence that liquid water still runs across its surface. "Water today on Mars was suggested previously, but it's not clear if those claims withstood follow-up studies," McEwen added. "That may prove true with … [Read more...] about CBS News Logo New evidence points to salt water on Mars
