| 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. |
| Growing 'mortality gap' detected between Democratic and Republican counties Posted: 09 Jun 2022 02:37 PM PDT Researchers examined mortality rates and federal and state election data for all counties in the U.S. from 2001 to 2019. The team found what they call a 'mortality gap' -- a widening difference between age-adjusted death rates in counties that had voted for a Democrat or a Republican in previous presidential and governor elections. |
| 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. |
| New research gives insights into how organelles divide in cells Posted: 09 Jun 2022 01:03 PM PDT A pioneering study has shed new light on how subcellular organelles divide and multiply. |
| 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. |
| How 'viral dark matter' may help mitigate climate change Posted: 09 Jun 2022 12:58 PM PDT A deep dive into the 5,500 marine RNA virus species scientists recently identified has found that several may help drive carbon absorbed from the atmosphere to permanent storage on the ocean floor. |
| As the ocean heats up hungrier predators take control Posted: 09 Jun 2022 12:58 PM PDT A hotter ocean is a hungrier ocean -- at least as far as fish predators are concerned. Scientists have discovered predator impacts in the Atlantic and Pacific peak at higher temperatures. The effects cascade down to transform other life in the ocean, potentially disrupting balances that have existed for millennia. |
| Superworms capable of munching through plastic waste Posted: 09 Jun 2022 12:58 PM PDT Researchers have found a species of worm with an appetite for polystyrene could be the key to plastic recycling on a mass scale. |
| Bioarchaeological evidence of very early Islamic burials in the Levant Posted: 09 Jun 2022 12:57 PM PDT A new study combining archaeological, historical and bioarchaeological data provides new insights into the early Islamic period in modern-day Syria. The research team was planning to focus on a much older time period but came across what they believe to be remains of early Muslims in the Syrian countryside. |
| 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. |
| Ground-breaking number of brown dwarfs discovered Posted: 09 Jun 2022 10:19 AM PDT Brown dwarfs, mysterious objects that straddle the line between stars and planets, are essential to our understanding of both stellar and planetary populations. However, only 40 brown dwarfs could be imaged around stars in almost three decades of searches. An international team has directly imaged a remarkable four new brown dwarfs thanks to a new innovative search method. |
| One-third of Greenlanders are at genetic risk for high cholesterol and cardiovascular disease Posted: 09 Jun 2022 10:19 AM PDT A genetic variant that is present in nearly 30% of Greenlanders is linked to high cholesterol and an increased risk of cardiovascular disease, according to a new study. |
| Chromatin originated in ancient microbes one to two billion years ago Posted: 09 Jun 2022 10:19 AM PDT Researchers now reveal that nature's storage solution first evolved in ancient microbes living on Earth between one and two billion years ago. |
| 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. |
| 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. |
| Genetic study offers new insights into DCIS biology, progression Posted: 09 Jun 2022 10:19 AM PDT A new genetic study discovered that not all breast cancers that develop after DCIS arise from the original DCIS lesion. Roughly 1 in 5 are new cancers, genetically unrelated to the original DCIS. |
| Recurring brain tumors shaped by genetic evolution and microenvironment Posted: 09 Jun 2022 10:18 AM PDT Researchers have discovered that infiltrating gliomas, a common brain and spinal cord tumor, are shaped by their genetic evolution and microenvironment, a finding that could lead to more targeted treatments. |
| Artificial intelligence reveals a never-before described 3D structure in rotavirus spike protein Posted: 09 Jun 2022 10:18 AM PDT The tip of rotavirus B spike protein is not only totally different from the corresponding structure in rotavirus A and C, but also no other protein before had been reported to have this structure. |
| New insights into how cyanobacteria regulate zinc uptake in the open ocean Posted: 09 Jun 2022 10:18 AM PDT An interdisciplinary research team has identified a remarkably efficient regulatory network that controls zinc accumulation in the open ocean cyanobacterium Synechococcus. |
| Researchers discover new genetic eye disease Posted: 09 Jun 2022 10:18 AM PDT Researchers have identified a new disease that affects the macula, a small part of the light-sensing retina needed for sharp, central vision. |
| Scientists determine structure of key factor in RNA quality control Posted: 09 Jun 2022 10:18 AM PDT In biology, getting rid of stuff can be just as important as making it. A buildup of cells, proteins, or other molecules that are no longer needed can cause problems, so living things have evolved several ways to clean house. |
| Health: Higher fish consumption may be associated with increased melanoma risk Posted: 09 Jun 2022 05:20 AM PDT Eating higher levels of fish, including tuna and non-fried fish, appears to be associated with a greater risk of malignant melanoma, suggests a large study of US adults. |
