Published The Crab Nebula seen in new light by NASA's Webb
(via sciencedaily.com) Original source NASA's James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 CE by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and after-effects of supernovae through thorough study of the Crab, a relatively nearby example.
Published Amphibians have one more thing to worry about--mercury
(via sciencedaily.com) Original source The first widescale assessment of methylmercury in adult amphibians in the U.S. to date shows that, in amphibians, this toxic compound is common, widespread and, at least for some, can reach very high levels.
Published To advance space colonization, new research explores 3D printing in microgravity
(via sciencedaily.com) Original source Research into how 3D printing works in a weightless environment aims to support long-term exploration and habitation on spaceships, the moon or Mars.
Published The importance of the Earth's atmosphere in creating the large storms that affect satellite communications
(via sciencedaily.com) Original source Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a high concentration of ions and free electrons, in determining how such storms develop. Understanding the interactions that cause large geomagnetic storms is important because they can disrupt radio signals and GPS. Their findings may help predict storms with the greatest potential consequences.
Published Protein root discovery seals future of climate-proof plants
(via sciencedaily.com) Original source Researchers have discovered a protein that seals plant roots to regulate the uptake of nutrients and water from the soil, the discovery could help develop climate proof crops that require less water and chemical fertilizers.
Published Uranus aurora discovery offers clues to habitable icy worlds
(via sciencedaily.com) Original source Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
Published Endangered whales live in area earmarked for gas exploration
(via sciencedaily.com) Original source Endangered whales and dolphins live year-round in an area of the Mediterranean earmarked for oil and gas exploration, new research shows.
Published Deep learning speeds up galactic calculations
(via sciencedaily.com) Original source Supernovae, exploding stars, play a critical role in the formation and evolution of galaxies. However, key aspects of them are notoriously difficult to simulate accurately in reasonably short amounts of time. For the first time, a team of researchers apply deep learning to the problem of supernova simulation. Their approach can speed up the simulation of supernovae, and therefore of galaxy formation and evolution as well. These simulations include the evolution of the chemistry which led to life.
Published Massive space explosion observed creating elements needed for life
(via sciencedaily.com) Original source Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
Published Scientists discover molten layer covering Martian core
(via sciencedaily.com) Original source NASA's InSight mission to Mars helped scientists map out Mars' internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars' metallic core -- providing new insights into how Mars formed, evolved and became the barren planet it is today.
Published First detection of heavy element from star merger
(via sciencedaily.com) Original source A team of scientists has used multiple space and ground-based telescopes to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion's aftermath.
Published Research reveals three new marsupial species -- though all likely extinct
(via sciencedaily.com) Original source The exciting discovery of three new species of a small Australian marsupial has been tempered by the sad fact that each of the newly identified species of mulgara is likely already extinct.
Published Solar farms in space are possible
(via sciencedaily.com) Original source It's viable to produce low-cost, lightweight solar panels that can generate energy in space, according to new research.
Published Scientists uncover cause of mysterious deaths of elephants in Zimbabwe
(via sciencedaily.com) Original source A bacterium, closely associated with deadly septicaemia, could have caused the deaths of six African elephants in Zimbabwe and possibly more in neighboring countries. The findings place infectious diseases on the list of pressures on African elephants, whose populations continue to be under threat.
Published Astrophysicists scan the Galaxy for signs of life
(via sciencedaily.com) Original source Astrophysicists are scanning the Universe for 'technosignatures' emanating from distant planets that would provide support for the existence of intelligent, alien life. Researchers plan to monitor millions of star systems.
Published Researchers capture first images of a radio 'ring of fire' solar eclipse
(via sciencedaily.com) Original source Researchers have recorded images of a solar eclipse with the 'ring of fire' effect in radio waves.
Published Discovery finds ferns produce crop-saving insecticide
(via sciencedaily.com) Original source Researchers have solved the structure of a novel insecticidal protein that is effective in protecting major crop plants like corn and soybean from pests and is naturally produced by ferns.
Published Researchers probe how a piece of the moon became a near-Earth asteroid
(via sciencedaily.com) Original source Two years after the striking discovery that a near-Earth asteroid could be a chunk of the moon, another UArizona research group has found that a rare pathway could have enabled this to happen.
Published Plants transformed into detectors of dangerous chemicals
(via sciencedaily.com) Original source What if your house plant could tell you your water isn't safe? Scientists are closer to realizing this vision, having successfully engineered a plant to turn beet red in the presence of a banned, toxic pesticide.
Published NASA's Webb discovers new feature in Jupiter's atmosphere
(via sciencedaily.com) Original source NASA's James Webb Space Telescope has discovered a new, never-before-seen feature in Jupiter's atmosphere. The high-speed jet stream, which spans more than 3,000 miles (4,800 kilometers) wide, sits over Jupiter's equator above the main cloud decks. The discovery of this jet is giving insights into how the layers of Jupiter's famously turbulent atmosphere interact with each other, and how Webb is uniquely capable of tracking those features.
