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 In Prehispanic Cancun, immigrants were treated just like Maya locals
(via sciencedaily.com) Original source Ancient people immigrated to Cancun Island and were treated just like locals, according to a new study.
Published Climate change likely impacted human populations in the Neolithic and Bronze Age
(via sciencedaily.com) Original source Human populations in Neolithic Europe fluctuated with changing climates, according to a new study.
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 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 Curiosity rover finds new evidence of ancient Mars rivers, a key signal for life
(via sciencedaily.com) Original source New analysis of data from the Curiosity rover reveals that much of the craters on Mars today could have once been habitable rivers.
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 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 The Moon is 40 million years older than previously thought
(via sciencedaily.com) Original source By analyzing tiny lunar crystals gathered by Apollo 17 astronauts in 1972, researchers recalculated the age of the Earth's Moon. Although previous assessments estimated the Moon as 4.425 billion years old, the new study discovered it is actually 4.46 billion years old -- 40 million years older than previously thought.
Published Challenging prehistoric gender roles: Research finds that women were hunters, too
(via sciencedaily.com) Original source Anthropologists challenge the traditional view of men as hunters and women as gatherers in prehistoric times. Their research reveals evidence of gender equality in roles and suggests that women were physically capable of hunting. The study sheds light on the gender bias in past research and calls for a more nuanced understanding of prehistoric gender roles.
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.
Published Astronomers detect most distant fast radio burst to date
(via sciencedaily.com) Original source An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Large Telescope (VLT) in a galaxy so far away that its light took eight billion years to reach us. The FRB is also one of the most energetic ever observed; in a tiny fraction of a second it released the equivalent of our Sun's total emission over 30 years.
Published Researchers identify the oldest pieces of Baltic amber found on the Iberian Peninsula: imports began over 5,000 years ago
(via sciencedaily.com) Original source Baltic amber is a luxury material used in jewellery and handicrafts all over the world. Researchers have shown that Baltic amber arrived on the Iberian Peninsula at least in the 4th millennium BC, more than a millennium earlier than previously thought.
Published Black holes could come in 'perfect pairs' in an ever expanding Universe
(via sciencedaily.com) Original source Researchers have shown it's theoretically possible for black holes to exist in perfectly balanced pairs -- held in equilibrium by a cosmological force -- mimicking a single black hole.
Published The encounter between Neanderthals and Sapiens as told by their genomes
(via sciencedaily.com) Original source About 40,000 years ago, Neanderthals, who had lived for hundreds of thousands of years in the western part of the Eurasian continent, gave way to Homo sapiens, who had arrived from Africa. This replacement was not sudden, and the two species coexisted for a few millennia, resulting in the integration of Neanderthal DNA into the genome of Sapiens. Researchers have analyzed the distribution of the portion of DNA inherited from Neanderthals in the genomes of humans (Homo sapiens) over the last 40,000 years. These statistical analyses revealed subtle variations in time and geographical space.
Published Source of largest ever Mars quake revealed
(via sciencedaily.com) Original source Scientists have announced the results of an unprecedented collaboration to search for the source of the largest ever seismic event recorded on Mars. The study rules out a meteorite impact, suggesting instead that the quake was the result of enormous tectonic forces within Mars' crust.
Published Signatures of the Space Age: Spacecraft metals left in the wake of humanity's path to the stars
(via sciencedaily.com) Original source Using tools hitched to the nose cone of their research planes and sampling more than 11 miles above the planet's surface, researchers have discovered significant amounts of metals in aerosols in the atmosphere, likely from increasingly frequent launches and returns of spacecraft and satellites. That mass of metal is changing atmospheric chemistry in ways that may impact Earth's atmosphere and ozone layer.
Published A non-exploitative economy favored the splendor of the Iberian Peninsula's Copper Age communities
(via sciencedaily.com) Original source A study describes the productive forces of the Chalcolithic communities of the southern half of the Iberian Peninsula as being very diverse, both in the type of tasks performed and in intensity, with a high degree of cooperation and no apparent signs of dependence between the different types of settlements or of political centralization. The work, based on the analysis of macrolithic tool data and the additional support of bioarchaeological information, allows to confirm the large ditched enclosure of Valencina de la Concepción (Seville) as a macro-populated area, inhabited by thousands of people, and not only as a place of worship.
Published NASA's Webb captures an ethereal view of NGC 346
(via sciencedaily.com) Original source One of the greatest strengths of NASA's James Webb Space Telescope is its ability to give astronomers detailed views of areas where new stars are being born. The latest example, showcased here in a new image from Webb's Mid-Infrared Instrument (MIRI), is NGC 346 -- the brightest and largest star-forming region in the Small Magellanic Cloud.
Published Removal of magnetic spacecraft contamination within extraterrestrial samples easily carried out, researchers say
(via sciencedaily.com) Original source By demonstrating that spaceflight doesn’t adversely affect the magnetism of moon rocks, researchers underscore the exciting potential of studying the magnetic histories stored in these samples.
