The “Asian water tower” is losing 24 billion tonnes of groundwater every year
37+ min ago (542+ words) The research was led by Prof. Shudong Wang of the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS). The team sought to overcome two major obstacles to understanding groundwater in the region: limited on-the-ground data and the…...
A black hole shredded a “super sun” — but something strange may have survived
4+ day, 6+ hour ago (674+ words) A massive star has been torn apart and gradually consumed by a black hole in a spectacular event that scientists compared to "preparing a snack for lunch." Astronomers around the world observed the extreme encounter, and the event was presented…...
Paleontology rocked by organic molecules found in 66-million-year-old dinosaur bones
6+ day, 7+ min ago (623+ words) For decades, scientists generally assumed that fossilization destroyed the original organic molecules once present in bones, teeth, and other tissues. Under that view, proteins and other biological materials were not expected to survive for tens of millions of years. New…...
Scientists turn Starlink into a giant scanner for Earth’s upper atmosphere
1+ week, 20+ hour ago (322+ words) A New Way to Observe the Thermosphere Better measurements of thermospheric density could advance research into the upper atmosphere while also providing valuable information for space engineering. Motivated by both needs, researchers at Kyoto University developed a new technique for…...
Earth’s molten core suddenly reversed direction — and scientists don’t know why
1+ week, 5+ day ago (728+ words) Liquid iron in Earth's outer core can behave in surprising ways. Scientists discovered that a large flow of molten material deep beneath the Pacific Ocean changed direction for reasons that remain unclear. Data from ESA satellites helped researchers trace the…...
A tiny molecular basket unlocks a powerful new kind of chemistry
3+ week, 22+ hour ago (617+ words) Iron and oxygen interact in many important processes throughout the human body. The best-known example is hemoglobin, where iron binds dioxygen, meaning two oxygen atoms joined together, so oxygen can be carried through the bloodstream. Iron also forms highly reactive…...
Sweden’s hidden rare earth deposits could help break China’s grip
3+ week, 6+ day ago (656+ words) Swedish researchers are exploring how the country's mineral resources could support cleaner production of rare earth elements (REE) and the powerful magnets made from them. As part of the Sustainable materials and material flows research area, Martin Sahlberg is studying…...
NASA satellites are watching Earth's newest island rise from the sea
1+ mon, 1+ week ago (604+ words) "The good news is that there are huge opportunities to explore and learn using both government and commercial satellite platforms already in orbit," said Jim Garvin, the chief scientist at NASA's Goddard Space Flight Center. Satellites Reveal the Eruption From…...
Rare goblin shark filmed alive for the first time in the deep sea
1+ mon, 1+ week ago (552+ words) For the first time, scientists have documented live goblin sharks (Mitsukurina owstoni) thriving in their natural deep ocean environment. The historic observations, led by a University of Hawai'i at Mānoa research team, provide an unprecedented look at one of the…...
Record-breaking ocean drilling reveals why Japan's 2011 tsunami was so deadly
1+ mon, 2+ week ago (657+ words) Researchers have uncovered a hidden feature beneath the Pacific Ocean that helps explain why Japan's devastating 2011 earthquake and tsunami became so destructive. The discovery also offers new clues that could improve forecasts of future megaquakes and tsunamis. A new study…...
