‘Dyson spheres’ were theorized as a way to detect alien life. Scientists say they’ve found potential evidence kraken18 What would be the ultimate solution to the energy problems of an advanced civilization? Renowned British American physicist Freeman Dyson theorized it would be a shell made up of mirrors or solar panels that completely surrounds a star — harnessing all the energy it produces. “One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star, ” wrote Dyson in a 1960 paper in which he first explained the concept. https://http-kraken14.at 2krn.at If it sounds like science fiction, that’s because it is: Dyson took the idea from Olaf Stapledon’s 1937 novel “Star Maker, ” and he was always open about that. The late scientist was a professor emeritus at the Institute of Advanced Study in Princeton, New Jersey. Still, coming from a thinker who some in the scientific community say might have been worthy of a Nobel Prize early in his career, the concept took hold and the hypothetical megastructures became known as Dyson spheres, even though the physicist later clarified that they would actually consist of “a loose collection or swarm of objects traveling on independent orbits around the star.” In his paper, Dyson also noted that Dyson spheres would give off waste heat detectable as infrared radiation, and suggested that looking for that byproduct would be a viable method for searching for extraterrestrial life. However, he added that infrared radiation by itself would not necessarily mean extraterrestrial intelligence, and that one of the strongest reasons for searching for such sources was that new types of natural astronomical objects might be discovered. “Scientists (at the time) were largely receptive, not to the likelihood that alien civilisations would be found to exist, but that a search for waste heat would be a good place to look, ” said George Dyson, a technology writer and author and the second of Dyson’s six children, via email. “Science fiction, from ‘Footfall’ to ‘Star Trek, ’ took the idea and ran with it, while social critics adopted the Dyson sphere as a vehicle for questioning the wisdom of unlimited technological growth.” |

Plant-based ultraprocessed foods linked to heart disease, early death, study says https://http-kraken13.at kraken14.at Want to reduce your risk of developing chronic disease and live longer while also helping the planet? Eat a plant-based diet, experts say. Does that mean you can fill your plate with boxed macaroni and cheese, deep-dish frozen veggie pizza or fast-food French fries and have a doughnut or three for dessert? kraken14.at While all of those ultraprocessed choices may be meat-free, they are not without risk, said Duane Mellor, a registered dietitian and senior teaching fellow at Aston Medical School in Birmingham, United Kingdom. “We can’t always assume plant-based means healthy, as after all sugar is plant-based, ” Mellor said in a statement. “Many foods that do not contain animal products, which includes biscuits, crisps, confectionary and soft drinks, are technically plant-based but would not be considered essential as part of a healthy diet by the majority of people.” In fact, eating such plant-based junk foods dramatically raises bad cholesterol and hypertension and can lead to associated heart disease and early death, according to a new study authors call “the first” to show ultraprocessed plant foods are associated with an increase in the risk of cardiovascular diseases. https://at-kraken15.at kraken14.at “Eating plant-based products can be beneficial, acting as protection against health problems, or it can represent a risk — it all depends on the level of processing of these foods, ” said senior study author Renata Levy, a researcher in the Epidemiological Research Center in Nutrition and Health at the University of Sao Paulo, known as Nupens/USP, in Brazil. Ultraprocessed foods undergo multiple industrial processes, such as heating, fracking of nutrients and proteins, molding and compression, and have added chemicals to cosmetically alter color, smell, taste and texture. Foods in this category are formulated to be hyper-palatable to human taste buds and are often extremely convenient, requiring little to no preparation time. |
