| Wreck of historic royal ship discovered off the English coast Posted: 09 Jun 2022 04:50 PM PDT A royal shipwreck has been discovered off the English coast. The wreck is of one of the most famous ships of the 17th century -- The Gloucester -- which sank 340 years ago while carrying the future King of England, James Stuart. Since running aground on a sandbank on May 6, 1682, the wreck has lain half-buried on the seabed, its exact whereabouts unknown. It has now been found. |

| Scientists discover new molecule that kills hard-to-treat cancers Posted: 09 Jun 2022 02:36 PM PDT A new molecule synthesized by a University of Texas at Dallas researcher kills a broad spectrum of hard-to-treat cancers, including triple-negative breast cancer, by exploiting a weakness in cells not previously targeted by other drugs. |
| Learning and remembering movement Posted: 09 Jun 2022 02:36 PM PDT Researchers examining the brain at a single-neuron level found that computation happens not just in the interaction between neurons, but within each individual neuron. Each of these cells, it turns out, is not a simple switch, but a complicated calculating machine. This discovery promises changes not only to our understanding of how the brain works, but better understanding of conditions ranging from Parkinson's disease to autism. The findings are also expected to advance machine learning, offering inspiration for new architectures. |

| Yellowstone's history of hydrothermal explosions over the past 14,000 years Posted: 09 Jun 2022 12:58 PM PDT While much of public attention on Yellowstone focuses on its potential to produce large supereruptions, the hazards that are much more likely to occur are smaller, violent hydrothermal explosions. Hydrothermal explosions occur when near-boiling water suddenly flashes into steam, releasing large amounts of energy. The energy release fractures the rock downward, often leaving behind a crater. The same sources that can produce these explosions are what give Yellowstone its well-known hot springs, geysers, and fumaroles. |

| Why people don't view the world the same way others do Posted: 09 Jun 2022 10:20 AM PDT Why are we so sure that the way we see people, situations and politics is accurate, and the way other people see them is foolishly wrong? The answer, according to new research lies in a region of the brain he calls the 'gestalt cortex,' which helps people make sense of information that is ambiguous or incomplete -- and dismiss alternative interpretations. |

| Pre-historic Wallacea: A melting pot of human genetic ancestries Posted: 09 Jun 2022 10:19 AM PDT The Wallacean islands of present-day Eastern Indonesia have a long history of occupation by modern humans. Notably, the maritime expansion of Austronesian speakers into Wallacea left archaeological traces of a Neolithic lifestyle and a genetic imprint still detectable in Eastern Indonesians today. To gain further insights into Wallacea's settlement history, scientists sequenced and analyzed sixteen ancient genomes from different islands of Wallacea, finding evidence for repeated genetic admixtures starting at least 3,000 years ago. |
| 'Fantastic giant tortoise,' believed extinct, confirmed alive in the Galápagos Posted: 09 Jun 2022 10:19 AM PDT A tortoise from a Galápagos species long believed extinct has been found alive. Fernanda, named after her Fernandina Island home, is the first of her species identified in more than a century. Geneticist successfully extracted DNA from a specimen collected from the same island more than a century ago and confirmed that Fernanda and the museum specimen are members of the same species and genetically distinct from all other Galápagos tortoises. |
| Photosynthesis-inspired process makes commodity chemicals Posted: 09 Jun 2022 10:19 AM PDT A team used light and water to convert acetylene into ethylene, a widely used, highly valuable chemical that is a key ingredient in plastics. While this conversion typically requires high temperatures and pressures, flammable hydrogen and expensive metals to drive the reaction, a photosynthesis-like process is much less expensive and less energy intensive. Not only is the new process environmentally friendly, it also works incredibly well -- successfully converting nearly 100% of acetylene into ethylene with 99% selectivity. |
| Posted: 09 Jun 2022 10:19 AM PDT The Japan Aerospace Exploration Agency's Hayabusa2 mission returned uncontaminated primitive asteroid samples to Earth. A comprehensive analysis of 16 particles from the asteroid Ryugu revealed many insights into the processes that operated before, during and after the formation of the solar system, with some still shaping the surface of the present-day asteroid. Elemental and isotopic data revealed that Ryugu contains the most primitive pre-solar nebular (an ancient disk of gas and dust surrounding what would become the Sun) material yet identified and that some organic materials may have been inherited from before the solar system formed. |
