Published Mapping the world's fungi from air samples
(via sciencedaily.com) Original source Researchers have found that the key to a quick and cost-effective mapping of biodiversity has been right in front of our eyes all along, but at the same time invisible -- i.e., in the air that surrounds us.
Published Dark matter in dwarf galaxy tracked using stellar motions
(via sciencedaily.com) Original source The qualities and behavior of dark matter, the invisible 'glue' of the universe, continue to be shrouded in mystery. Though galaxies are mostly made of dark matter, understanding how it is distributed within a galaxy offers clues to what this substance is, and how it's relevant to a galaxy's evolution.
Published Mars likely had cold and icy past, new study finds
(via sciencedaily.com) Original source The question of whether Mars ever supported life has captivated the imagination of scientists and the public for decades. Central to the discovery is gaining insight into the past climate of Earth's neighbor: was the planet warm and wet, with seas and rivers much like those found on our own planet? Or was it frigid and icy, and therefore potentially less prone to supporting life as we know it? A new study finds evidence to support the latter by identifying similarities between soils found on Mars and those of Canada's Newfoundland, a cold subarctic climate.
Published Planted mangroves' ability to store carbon
(via sciencedaily.com) Original source Ecologists have published new findings on how planted mangroves can store up to 70% of carbon stock to that found in intact stands after only 20 years.
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 Mozambican Woodlands could store more than double the carbon previously estimated
(via sciencedaily.com) Original source The capacity of Mozambican woodlands to capture and store carbon is underestimated and potentially undervalued for their protection and restoration, finds new research from an international team of scientists.
Published Not so simple: Mosses and ferns offer new hope for crop protection
(via sciencedaily.com) Original source Mosses, liverworts, ferns and algae may offer an exciting new research frontier in the global challenge of protecting crops from the threat of disease.
Published Wolves' return has had only small impact on deer populations in NE Washington
(via sciencedaily.com) Original source Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
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 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 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 Study examines tree adaptability to climate change
(via sciencedaily.com) Original source Many trees could expand their ranges by more than 25 percent based on their potential temperature tolerances.
Published Global database reveals large gaps in our knowledge of four-footed animals
(via sciencedaily.com) Original source Researchers developed TetrapodTraits -- a global database of animals with four feet -- which can now be applied for better ecology, evolution and conservation research.
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 First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published How a plant app helps identify the consequences of climate change
(via sciencedaily.com) Original source A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
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 Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change
(via sciencedaily.com) Original source New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming.
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 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.
