Published Greater focus needed on how existing international law can prevent the increasing militarization of outer space
(via sciencedaily.com) Original source There is a pressing need for countries and international organizations to understand better how existing international law can help them address serious concerns about the militarization of outer space, a new study says.
Published The origins of dark comets
(via sciencedaily.com) Original source Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have been one route for delivering water to Earth, according to a new study.
Published The plague may have caused the downfall of the Stone Age farmers
(via sciencedaily.com) Original source Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research shows.
Published Strong evidence for intermediate-mass black hole in Omega Centauri
(via sciencedaily.com) Original source Most known black holes are either extremely massive, like the supermassive black holes that lie at the cores of large galaxies, or relatively lightweight, with a mass of under 100 times that of the Sun. Intermediate-mass black holes (IMBHs) are scarce, however, and are considered rare 'missing links' in black hole evolution.
Published Archaeologists report earliest evidence for plant farming in east Africa
(via sciencedaily.com) Original source A trove of ancient plant remains excavated in Kenya helps explain the history of plant farming in equatorial eastern Africa, a region long thought to be important for early farming but where scant evidence from actual physical crops has been previously uncovered.
Published Found with Webb: A potentially habitable icy world
(via sciencedaily.com) Original source A international team of astronomers has made an exciting discovery about the temperate exoplanet LHS 1140 b: it could be a promising 'super-Earth' covered in ice or water.
Published Building materials for water-rich planets in the early solar system
(via sciencedaily.com) Original source Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These planetesimals continually supplied building materials for planets -- also for the Earth, whose original material contained little water. The Earth received its actual water through planetesimals, which emerged at low temperatures in the outer solar system, as shown by computational models carried out by an international research teach with participation by earth scientists.
Published New way for beneficial microbes to survive extreme conditions and space exploration
(via sciencedaily.com) Original source Investigators sought to help figure out how to send materials like probiotics into space and to better treat a variety of gastrointestinal (GI) and metabolic diseases. The team's formulations allow microbial therapeutics, including those used to treat gastrointestinal diseases and improve crop production, to maintain their potency and function over time despite extreme temperatures.
Published Stench of a gas giant? Nearby exoplanet reeks of rotten eggs, and that's a good thing
(via sciencedaily.com) Original source An exoplanet infamous for its deadly weather has been hiding another bizarre feature -- it reeks of rotten eggs, according to a new study of data from the James Webb Space Telescope.
Published Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breeds
(via sciencedaily.com) Original source A study of ancient dingo DNA revealed that the distribution of modern dingoes across Australia, including those on K'gari (formerly Fraser Island), pre-dates European colonization and interventions like the dingo-proof fence.
Published Fresh wind blows from historical supernova
(via sciencedaily.com) Original source A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary 'guest star,' now labeled supernova (SN) 1181, which was recorded in historical documents in Japan and elsewhere in Asia. However, after the star dimmed, its location and structure remained a mystery until a team pinpointed its location in 2021. Now, through computer modeling and observational analysis, researchers have recreated the structure of the remnant white dwarf, a rare occurrence, explaining its double shock formation. They also discovered that high-speed stellar winds may have started blowing from its surface within just the past 20-30 years. This finding improves our understanding of the diversity of supernova explosions, and highlights the benefits of interdisciplinary research, combining history with modern astronomy to enable new discoveries about our galaxy.
Published Moon 'swirls' could be magnetized by unseen magmas
(via sciencedaily.com) Original source Mysterious, light-colored swirls on Moon's surface could be rocks magnetized by magma activity underground, laboratory experiments confirm.
Published Machine learning could aid efforts to answer long-standing astrophysical questions
(via sciencedaily.com) Original source Physicists have developed a computer program incorporating machine learning that could help identify blobs of plasma in outer space known as plasmoids. In a novel twist, the program has been trained using simulated data.
Published Extinct humans survived on the Tibetan plateau for 160,000 years
(via sciencedaily.com) Original source Bone remains found in a Tibetan cave 3,280 m above sea level indicate an ancient group of humans survived here for many millennia.
Published Neutrons on classically inexplicable paths
(via sciencedaily.com) Original source Is nature really as strange as quantum theory says -- or are there simpler explanations? New neutron measurements prove: It doesn't work without the strange properties of quantum theory.
Published Organic material from Mars reveals the likely origin of life's building blocks
(via sciencedaily.com) Original source Two samples from Mars together deliver clear evidence of the origin of Martian organic material. The study presents solid evidence for a prediction made over a decade ago that could be key to understanding how organic molecules, the foundation of life, were first formed here on Earth.
Published A new pulsar buried in a mountain of data
(via sciencedaily.com) Original source Astronomers have discovered the first millisecond pulsar in the stellar cluster Glimpse-CO1.
Published The evidence is mounting: humans were responsible for the extinction of large mammals
(via sciencedaily.com) Original source Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.
Published This desert moss has the potential to grow on Mars
(via sciencedaily.com) Original source The desert moss Syntrichia caninervis is a promising candidate for Mars colonization thanks to its extreme ability to tolerate harsh conditions lethal to most life forms. The moss is well known for its ability to tolerate drought conditions, but researchers now report that it can also survive freezing temperatures as low as 196 C, high levels of gamma radiation, and simulated Martian conditions involving these three stressors combined. In all cases, prior dehydration seemed to help the plants cope.
Published The beginnings of fashion
(via sciencedaily.com) Original source A team of researchers suggest that eyed needles were a new technological innovation used to adorn clothing for social and cultural purposes, marking the major shift from clothes as protection to clothes as an expression of identity.
