Published Wobbling droplets in space confirm late professor's theory
(via sciencedaily.com) At a time when astronomers around the world are reveling in new views of the distant cosmos, an experiment on the International Space Station has given researchers fresh insight into something a little closer to home: water.
Published Harvesting resources on Mars with plasmas
(via sciencedaily.com) Researchers have devised a plasma-based way to produce and separate oxygen within the Martian environment. It's a complementary approach to NASA's Mars Oxygen In-Situ Resource Utilization Experiment and may deliver high rates of molecule production per kilogram of instrumentation sent to space. The team presents the method for harnessing and processing local resources to generate products on Mars.
Published Weird and wonderful world of fungi shaped by evolutionary bursts, study finds
(via sciencedaily.com) Scientists have discovered that the vast anatomical variety of fungi stems from evolutionary increases in multicellular complexity.
Published Building on the moon and Mars? You'll need extraterrestrial cement for that
(via sciencedaily.com) Researchers are exploring ways to use clay-like topsoil materials from the moon or Mars as the basis for extraterrestrial cement that could be used by astronauts to create building materials for life in outer space. Scientists have converted simulated lunar and Martian soils into geopolymer cement, which is considered a good substitute for conventional cement.
Published How a harmful fungus renders its host plant defenseless
(via sciencedaily.com) The fungus Ustilago maydis attacks corn and can cause significant damage to its host. To do this, it first ensures that the plant offers little resistance to the infection. The surgical precision it applies is shown by a new study.
Published Drought increases microbe-laden dust landing in Sierras
(via sciencedaily.com) Dust from all over the world is landing in the Sierra Nevada mountains carrying microbes that are toxic to both plants and humans. New research shows higher concentrations of the dust are landing at lower elevations, where people are more likely to be hiking.
Published Robotic motion in curved space defies standard laws of physics
(via sciencedaily.com) Researchers have proven that when bodies exist in curved spaces, they can in fact move without pushing against something.
Published As reflective satellites fill the skies, students are making sure astronomers can adapt
(via sciencedaily.com) Students have completed a comprehensive brightness study to characterize mega-constellation satellites cluttering the skies.
Published Global spread of powdery mildew through migration and trade
(via sciencedaily.com) The worldwide distribution of one of the most important cereal pathogens is the result of human activity. Researchers have traced the history and spread of wheat powdery mildew along wheat trade routes and found that mixing of genetic ancestries of related powdery mildew species played a central role in the evolution and adaptation of the pathogen.
Published This is how highly resistant strains of fungi emerge
(via sciencedaily.com) Antibiotic resistance is a matter of common knowledge. And the same phenomenon also occurs with drugs against pathogenic fungi. What causes it is still not very well understood.
Published Webb captures stellar gymnastics in the Cartwheel Galaxy
(via sciencedaily.com) NASA's James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy's central black hole.
Published Modeling reveals how dwarf planet Ceres powers unexpected geologic activity
(via sciencedaily.com) Original source For a long time, our view of Ceres was fuzzy, according to a geoscientist. A dwarf planet and the largest body found in the asteroid belt -- the region between Jupiter and Mars speckled with hundreds of thousands of asteroids -- Ceres had no distinguishable surface features in existing telescopic observations from Earth.
Published Space travel: Bone aging in fast forward
(via sciencedaily.com) Long periods in space damage bone structure irreparably in some cases and can make parts of the human skeleton age prematurely by up to 10 years, according to new research. Adapted training programs in conjunction with medication could provide better protection for astronauts on future space missions. The research findings also have implications for treating rheumatic conditions in clinical practice.
Published New bioremediation material to clean up 'forever chemicals'
(via sciencedaily.com) Original source A novel bioremediation technology for cleaning up per- and polyfluoroalkyl substances, or PFAS, chemical pollutants that threaten human health and ecosystem sustainability, has been developed. The material has potential for commercial application for disposing of PFAS, also known as 'forever chemicals.'
Published Scientists discover places on the moon where it's always 'sweater weather'
(via sciencedaily.com) A team led by planetary scientists has discovered shady locations within pits on the moon that always hover around a comfortable 63 degrees Fahrenheit. The pits, and caves to which they may lead, would make safer, more thermally stable base camps for lunar exploration and long-term habitation than the rest of the moon's surface, which heats up to 260 degrees during the day and drops to 280 degrees below zero at night.
Published Wine-drinkers of the world rejoice! New research finds key to billion-dollar problem
(via sciencedaily.com) Original source Grapevine Trunk Diseases, or GTDs, are the bane of vineyard owners worldwide, and as of 2012, were responsible for more than $1.5 billion in annual economic damages. While researchers have long known that a host of pathogenic fungi combine to gang up on grapevines, the mechanics of how these GTD-causing fungi work has remained a mystery.
Published Explosive volcanic eruption produced rare mineral on Mars
(via sciencedaily.com) Planetary scientists have an answer to a mystery that's puzzled the Mars research community since NASA's Curiosity rover discovered a mineral called tridymite in Gale Crater in 2016.
Published Why Jupiter doesn't have rings like Saturn
(via sciencedaily.com) Because it's bigger, Jupiter ought to have larger, more spectacular rings than Saturn has. But new research shows Jupiter's massive moons prevent that vision from lighting up the night sky.
Published Global map of lunar hydrogen: Data confirms role water played in moon's formation
(via sciencedaily.com) Original source Using data collected over two decades ago, scientists have compiled the first complete map of hydrogen abundances on the Moon's surface. The map identifies two types of lunar materials containing enhanced hydrogen and corroborates previous ideas about lunar hydrogen and water, including findings that water likely played a role in the Moon's original magma-ocean formation and solidification.
Published Deep dive into the dusty Milky Way
(via sciencedaily.com) Original source An animated dive into the dusty Milky Way reveals the outlines of our galaxy taking shape as we look out further and further from Earth. Based on new data from an interactive tool that exploits data from the European Space Agency's Gaia mission and other space science data sets, astronomers have created an animation to model dust in the Milky Way.
