The approach uses an innovative copper-containing polymeric filter and essentially converts CO2 into sodium bicarbonate (aka baking soda) that can be released harmlessly into the ocean. This new hybrid material, or filter, is called DeCarbonHIX (i.e., decarbonization through hybrid ion exchange material). The research has demonstrated a 300 percent increase in the amount of carbon captured compared with existing direct air capture methods.]]> Fri, 31 Mar 2023 19:15:14 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWiO6PIhfEGHJJVjH6qdYdAk https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjtRh44B7E3TOzdsCmHakzH Indigenous peoples as far north as Wyoming and Idaho may have begun to care for horses by the first half of the 17th Century, according to a new study by researchers from 15 countries and multiple Native American groups.]]> Thu, 30 Mar 2023 23:21:29 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjtRh44B7E3TOzdsCmHakzH https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWhF2HyqlEwlG-zdsCmHakzH Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy -- the most distant detection of such hot gas yet.

The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI). The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 450 degrees Fahrenheit) and suggests that it has no significant atmosphere.]]> Mon, 27 Mar 2023 22:32:27 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj7CXSFd8sQpnn9ye8UNv30 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj7CXSFd8sQpqCY3L745TL_ A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; about 2500 gigatons of carbon means permanent loss of nearly the entire ice sheet. Having emitted about 500 gigatons of carbon, we're about halfway to the first tipping point.]]> Mon, 27 Mar 2023 22:32:12 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWj7CXSFd8sQpqCY3L745TL_ https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWirPO5MzGUalOT5HJgy6HUf Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement between dissimilar particles -- something rare in quantum studies.]]> Sat, 25 Mar 2023 00:44:00 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWirPO5MzGUalOT5HJgy6HUf https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWicY1LlnBCPG5s0ohxaO6Yr Many people who have dieted are familiar with the yo-yo effect: after the diet, the kilos are quickly put back on. Researchers have now shown in mice that communication in the brain changes during a diet: The nerve cells that mediate the feeling of hunger receive stronger signals, so that the mice eat significantly more after the diet and gain weight more quickly. In the long term, these findings could help developing drugs to prevent this amplification and help to maintain a reduced body weight after dieting.]]> Fri, 24 Mar 2023 19:52:18 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWicY1LlnBCPG5s0ohxaO6Yr https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWiVFWwDcZjVP5VjH6qdYdAk Volcanic relics scattered throughout the Australian landscape are a map of the northward movement of the continent over a 'hotspot' inside the Earth, during the last 35 million years.]]> Fri, 24 Mar 2023 15:35:18 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWiVFWwDcZjVP5VjH6qdYdAk https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWjq4flEc1swHiejEQ2Mq9rY Metabolic pathways consist of a series of biochemical reactions in cells that convert a starting component into other products.

Schmidt, describe his malady -- his progressive hearing loss -- to the world upon his death so that 'as far as possible at least the world will be reconciled to me after my death.' Now, more than two centuries later, a team of researchers have partially fulfilled his wish by analyzing DNA they lifted and pieced together from locks of his hair.]]> Wed, 22 Mar 2023 20:09:29 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWgffKIV1_sOVJVjH6qdYdAk https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWiUYI-oYWht1-zdsCmHakzH Engineers have developed a new water treatment that removes 'forever chemicals' from drinking water safely, efficiently -- and for good.]]> Wed, 22 Mar 2023 20:04:03 +0200 https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWiUYI-oYWht1-zdsCmHakzH https://api.follow.it/track-rss-story-click/v3/NRKQAjooaWiUYI-oYWht16CY3L745TL_ When the first interstellar comet ever seen in our solar system was discovered in 2017, one characteristic -- an unexplained acceleration away from the sun -- sparked wild speculation, including that it was an alien spacecraft. An astrochemist found a simpler explanation and tested it with an astronomer: in interstellar space, cosmic rays converted water to hydrogen in the comet's outer layers.
