As global air temperatures increase, the number of Antarctic meteorites shrinks. By 2050, about a quarter of the 3-800,000 meteorites there will melt away, according to a report from a team of researchers from Switzerland and Belgium. The team drew upon artificial intelligence, satellite observations, and climate model projections to determine that, for every tenth of a degree increase in global air temperature, an average of nearly 9,000 meteorites will disappear from Antarctica’s ice sheet.T ...read more
At the heart of humanity’s grand odyssey into the cosmos lies a problem that needs to be solved. The success of our final frontier journey — the reality of settling humans long-term on the moon, Mars, and beyond — hinges on our ability to cultivate our own sustainable sustenance.Transforming harsh, disagreeable lunar and Martian soil into a nurturing medium suitable for terrestrial plants is no easy task. Yet, it’s one that has fascinated graduate students Jessica Atkin of Texas A&M ...read more
The moon’s formation has been theoretically topsy-turvy for decades. Parts of the original molten magma surface sank below the crust. Over millennia, dense minerals mixed with the mantle, melted, and returned to the surface as titanium-rich lava flows. A paper in Nature Geoscience details and confirms this transformation."Our moon literally turned itself inside out," said Jeff Andrews-Hanna, a University of Arizona Lunar and Planetary Laboratory scientist and co-author of the study, in a press ...read more
A case report published on March 24, 2024 in The Lancet is helping researchers gain new insights into a poorly understood neurological disorder. The case is that of Victor Sharrah, a 58-year-old man who complained about seeing “demonic” faces for nearly three years. Everything else he views appears normal.What makes Sharrah’s case special is that faces in photographs or on a computer screen remain normal — he only sees the demonic features when looking at a real face. In his own words, ...read more
In 1912, Polish biochemist Kazimierz Funk isolated a chemical compound he thought gave brown rice its protective properties. He coined the phrase "vitamin,” to describe it. Funk realized there were probably other compounds that had potential to fight certain health deficiencies. Between the time of his discovery, until 1948, all essential vitamins were identified. By the 1950s, mass production of vitamin supplements had begun, including the concept of a multivitamin. This marked the beginning ...read more
