Published Scientists lay out revolutionary method to warm Mars
(via sciencedaily.com) Original source Ever since we learned that the surface of planet Mars is cold and dead, people have wondered if there is a way to make it friendlier to life. The newly proposed method is over 5,000 times more efficient than previous schemes to globally warm Mars, representing a significant leap forward in our ability to modify the Martian environment.
Published Carvings at ancient monument may be world's oldest calendars
(via sciencedaily.com) Original source Markings on a stone pillar at a 12,000 year-old archaeological site in Turkey likely represent the world's oldest solar calendar, created as a memorial to a devastating comet strike, experts suggest.
Published Astronomers uncover risks to planets that could host life
(via sciencedaily.com) Original source A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed.
Published Scientists pin down the origins of the moon's tenuous atmosphere
(via sciencedaily.com) Original source Scientists say they have identified the main process that formed the moon's atmosphere and continues to sustain it today. The team reports that the lunar atmosphere is primarily a product of 'impact vaporization.'
Published Demographics of north African human populations unravelled using genomic data and artificial intelligence
(via sciencedaily.com) Original source A new study places the origin of the Imazighen in the Epipaleolithic, more than twenty thousand years ago. The research concludes that the genetic origin of the current Arab population of north Africa is far more recent than previously believed, placing it in the seventh century AD. The team has designed an innovative demographic model that uses artificial intelligence to analyze the complete genomes of the two populations.
Published Key to rapid planet formation
(via sciencedaily.com) Original source Researchers have developed a new model to explain the formation of giant planets such as Jupiter, which furnishes deeper insights into the processes of planet formation and could expand our understanding of planetary systems.
Published Scientists devise method to secure Earth's biodiversity on the moon
(via sciencedaily.com) Original source New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.
Published The corona is weirdly hot: Parker Solar Probe rules out one explanation
(via sciencedaily.com) Original source By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures.
Published NASA's Fermi finds new feature in brightest gamma-ray burst yet seen
(via sciencedaily.com) Original source In October 2022, astronomers were stunned by what was quickly dubbed the BOAT -- the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA's Fermi Gamma-ray Space Telescope reveals a feature never seen before.
Published Space-trekking muscle tests drugs for microgravity-induced muscle impairment
(via sciencedaily.com) Original source A gentle rumble ran under a researcher's feet as a rocket carrying her research -- live, human muscle cells grown on scaffolds fixed on tiny chips -- lifted off, climbed, and disappeared into the sky to the International Space Station National Laboratory. These chips would help her better understand muscle impairment, often seen in astronauts and older adults, and test drugs to counter the condition.
Published Dark matter flies ahead of normal matter in mega galaxy cluster collision
(via sciencedaily.com) Original source Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter.
Published Images of nearest 'super-Jupiter' open a new window to exoplanet research
(via sciencedaily.com) Original source Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.
Published Expiring medications could pose challenge on long space missions
(via sciencedaily.com) Original source A new study shows that over half of the medicines stocked in space -- staples such as pain relievers, antibiotics, allergy medicines, and sleep aids -- would expire before astronauts could return to Earth.
Published Hunter-gatherers kept an 'orderly home' in the earliest known British dwelling
(via sciencedaily.com) Original source Archaeological evidence from the world-famous Mesolithic site of Star Carr in North Yorkshire has shown that hunter-gatherers likely kept an orderly home by creating 'zones' for particular domestic activities.
Published Researchers explore the effects of stellar magnetism on potential habitability of exoplanets
(via sciencedaily.com) Original source A study extends the definition of a habitable zone for planets to include their star's magnetic field.
Published Life signs could survive near surfaces of Enceladus and Europa
(via sciencedaily.com) Original source Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life in the form of organic molecules (like amino acids and nucleic acids) could survive just under the surface ice despite the harsh, ionizing radiation on these worlds. If robotic landers were to go to these moons to look for life signs, they would not have to dig very deep to find amino acids that have survived being altered or destroyed by radiation.
Published New dawn for space storm alerts could help shield Earth's tech
(via sciencedaily.com) Original source Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.
Published Exoplanet-hunting telescope to begin search for another Earth in 2026
(via sciencedaily.com) Original source Europe's next big space mission -- a telescope that will hunt for Earth-like rocky planets outside of our solar system -- is on course to launch at the end of 2026. PLATO, or PLAnetary Transits and Oscillations of stars, is being built to find nearby potentially habitable worlds around Sun-like stars that we can examine in detail.
Published Another intermediate-mass black hole discovered at the center of our galaxy
(via sciencedaily.com) Original source So far, only about ten intermediate-mass black holes have been discovered in the entire universe. The newly identified black hole causes surrounding stars in a cluster to move in an unexpectedly orderly way.
Published Evidence for butchery of giant armadillo-like mammals in Argentina 21,000 years ago
(via sciencedaily.com) Original source Cut marks on fossils could be evidence of humans exploiting large mammals in Argentina more than 20,000 years ago, according to a new study.
