Published Potential first traces of the universe's earliest stars
(via sciencedaily.com) Original source Astronomers may have discovered the ancient chemical remains of the first stars to light up the Universe. Using an innovative analysis of a distant quasar observed by the 8.1-meter Gemini North telescope on Hawai'i, the scientists found an unusual ratio of elements that, they argue, could only come from the debris produced by the all-consuming explosion of a 300-solar-mass first-generation star.
Published Study links cold water shock to catastrophic coral collapse in the Eastern Pacific
(via sciencedaily.com) Scientists have discovered that an extreme weather event that resulted in rapid sea temperature drops of up to 10 degrees was the primary cause of a catastrophic coral die-off event off the coast of Costa Rica.
Published New nationwide strategy brings scientists, communities together to help reduce landslide risks
(via sciencedaily.com) Landslides are inevitable, but landslide disasters are not. With this in mind, the U.S. Geological Survey has released a new report that details the strategic actions necessary to equitably reduce the Nation's risk from landslide hazards.
Published Lunar glass shows Moon asteroid impacts mirrored on Earth
(via sciencedaily.com) A research team has found asteroid impacts on the Moon millions of years ago coincided precisely with some of the largest meteorite impacts on Earth, such as the one that wiped out the dinosaurs.
Published Scientists improve process for turning hard-to-recycle plastic waste into fuel
(via sciencedaily.com) Turning plastic waste into useful products through chemical recycling is one strategy for addressing Earth's growing plastic pollution problem. A new study may improve the ability of one method, called pyrolysis, to process hard-to-recycle mixed plastics -- like multilayer food packaging -- and generate fuel as a byproduct, the scientists said.
Published Study finds higher rates of traumatic injuries for outdoor workers during hotter weather
(via sciencedaily.com) Rates of traumatic injury among workers in the Oregon agricultural and construction sectors are significantly higher during periods of high heat compared with periods of more moderate weather, a recent study found.
Published Population boom near globe's vulnerable coral reefs
(via sciencedaily.com) Millions more people across the globe are relying on our endangered coral reefs than 20 years ago, according to new figures into population growth in coastal areas.
Published Hackmanite mineral changes color also upon exposure to nuclear radiation
(via sciencedaily.com) Researchers have long studied the color-changing properties of the natural mineral hackmanite upon exposure to UV radiation or X-rays. Now, the research group studied the reactions of synthetic hackmanite to nuclear radiation. The researchers discovered a one-of-a-kind and novel intelligent quality, gamma exposure memory, which allows the use of hackmanite as e.g. radiation detector.
Published Webb reveals a galaxy sparkling with the universe's oldest star clusters
(via sciencedaily.com) Using the James Webb Space Telescope (JWST), researchers have identified the most distant globular clusters ever discovered. These dense groups of millions of stars may be relics that contain the first and oldest stars in the universe. The early analysis of Webb's First Deep Field image depicts some of the universe's earliest galaxies.
Published Detailing a disastrous autumn day in ancient Italy
(via sciencedaily.com) The Plinian eruption of Mount Vesuvius around 4,000 years ago -- 2,000 years before the one that buried the Roman city of Pompeii -- left a remarkably intact glimpse into Early Bronze Age village life in the Campania region of Southern Italy. The village offers a rare glimpse into the lives of the people who lived there, and the degree of preservation led the researchers to pinpoint the timing of the eruption, based on archaeobotanical record.
Published New evidence for liquid water beneath the south polar ice cap of Mars
(via sciencedaily.com) An international team of researchers has revealed new evidence for the possible existence of liquid water beneath the south polar ice cap of Mars.
Published Mycobiome atlas describes associations between cancers and fungi
(via sciencedaily.com) Scientists have created the first pan-cancer mycobiome atlas -- a survey of 35 types of cancer and their associated fungi.
Published Milky Way's graveyard of dead stars found
(via sciencedaily.com) The first map of the 'galactic underworld' -- a chart of the corpses of once massive suns that have since collapsed into black holes and neutron stars -- has revealed a graveyard that stretches three times the height of the Milky Way, and that almost a third of the objects have been flung out from the galaxy altogether.
Published Ozone pollution threatens plant health and makes it harder for pollinators to find flowers
(via sciencedaily.com) Over the past decades, rising levels of ozone pollution have been interrupting pollination, impacting the livelihood of both plants and the animals that pollinate them. Researchers now explain how an excess of ground-level ozone can damage plant foliage, change plants' flowering patterns, and act as a barrier to pollinators finding blooms.
Published Dead fish breathes new life into the evolutionary origin of fins and limbs
(via sciencedaily.com) A trove of fossils in China, unearthed in rock dating back some 436 million years, have revealed for the first time that the mysterious galeaspids, a jawless freshwater fish, possessed paired fins.
Published More reasons to go solar when gearing up for a greener drive
(via sciencedaily.com) With electric vehicles sales soaring worldwide, potential buyers are not just weighing up the price tag, but also the logistics and expense of charging the planet-friendly cars. A new study shows households with solar panels and batteries will be the big winners.
Published Revealing the genome of the common ancestor of all mammals
(via sciencedaily.com) An international team has reconstructed the genome organization of the earliest common ancestor of all mammals. The reconstructed ancestral genome could help in understanding the evolution of mammals and in conservation of modern animals. The earliest mammal ancestor likely looked like the fossil animal 'Morganucodon' which lived about 200 million years ago.
Published As few as 1 in 5 COVID cases may have been counted worldwide, mathematical models suggest
(via sciencedaily.com) Mathematical models indicate that as few as one in five cases of COVID-19 which occurred during the first 29 months of the pandemic are accounted for in the half billion cases officially reported.
Published Rising global temperatures point to widespread drought
(via sciencedaily.com) More frequent and longer-lasting droughts caused by rising global temperatures pose significant risks to people and ecosystems around the world -- according to new research. The paper has quantified the projected impacts of alternative levels of global warming upon the probability and length of severe drought in the six countries.
Published The neighbors of the caliph: Archaeologists uncover ancient mosaics on the shore of the Sea of Galilee
(via sciencedaily.com) With the help of geomagnetic surface surveys and subsequent hands-on digging, an excavation team has revealed new insights into the area in which the caliph's palace of Khirbat al-Minya was built on the shores of the Sea of Galilee. According to these findings, there had already been a settlement occupied by Christian or Jewish inhabitants in the immediate vicinity long before the palace was built.
