Published Warming stops tiny organisms working together
(via sciencedaily.com) Original source Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
Published Scientists discover entirely new wood type that could be highly efficient at carbon storage
(via sciencedaily.com) Original source Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood.
Published What no one has seen before -- simulation of gravitational waves from failing warp drive
(via sciencedaily.com) Original source Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the realm of science fiction, it is based on concrete descriptions in general relativity. A new study takes things a step further -- simulating the gravitational waves such a drive might emit if it broke down.
Published Dark matter: A camera trap for the invisible
(via sciencedaily.com) Original source AI-powered image recognition could give researchers a new tool in hunt for dark matter.
Published From genes to jeans: New genetic insights may lead to drought resilient cotton
(via sciencedaily.com) Original source Cotton is woven into the very fabric of our lives, from soft T-shirts to comfortable jeans and cozy bedsheets. It's the world's leading renewable textile fiber and the backbone of a global industry worth billions. As climate change intensifies, cotton farmers face increasing challenges from drought and heat. However, new research offers hope for developing more resilient varieties that can maintain high yields even under water-stressed conditions.
Published Scientists untangle interactions between the Earth's early life forms and the environment over 500 million years
(via sciencedaily.com) Original source The atmosphere, the ocean and life on Earth interacted over the past 500-plus million years in ways that improved conditions for early organisms to thrive. Now, an interdisciplinary team of scientists has produced a perspective article of this co-evolutionary history.
Published Climate is most important factor in where mammals choose to live, study finds
(via sciencedaily.com) Original source Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.
Published Mixed approach to reforestation better than planting or regeneration alone
(via sciencedaily.com) Original source Reforestation in low- and middle-income countries can remove up to 10 times more carbon dioxide from the atmosphere at lower cost than previously estimated, making it a potentially more effective option to fight climate change. Most current reforestation programs focus on tree planting alone, but the study estimates that nearly half of all suitable reforestation locations would be more effective at sequestering carbon if forests were allowed to grow back naturally.
Published How well does tree planting work in climate change fight? It depends
(via sciencedaily.com) Original source Using trees as a cost-effective tool against climate change is more complicated than simply planting large numbers of them, an international collaboration has shown.
Published Trees reveal climate surprise -- bark removes methane from the atmosphere
(via sciencedaily.com) Original source Tree bark surfaces play an important role in removing methane gas from the atmosphere.
Published Biosensor reveals gibberellin's critical role in legume nitrogen-fixation -- paving the way for self-fertilizing cereals
(via sciencedaily.com) Original source Researchers demonstrate that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size.
Published Heat-sensitive trees move uphill seeking climate change respite
(via sciencedaily.com) Original source Trees in the Brazilian Atlantic Forest are migrating in search of more favourable temperatures with species in mountain forests moving uphill to escape rising heat caused by climate change.
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 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 Groundcherry gets genetic upgrades: Turning a garden curiosity into an agricultural powerhouse
(via sciencedaily.com) Original source Imagine a small fruit that tastes like a cross between a tomato and a pineapple, wrapped in its own natural paper lantern. That's the groundcherry (Physalis grisea) -- a little-known relative of tomatoes that's been quietly growing in gardens and small farms across North America for centuries. Now, this humble fruit is getting a 21st-century upgrade thanks to some cutting-edge genetic research.
Published Reef pest feasts on 'sea sawdust'
(via sciencedaily.com) Original source Researchers have uncovered an under the sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as 'sea sawdust'.
Published Discovery of a hybrid lineage offers clues to how trees adapt to climate change
(via sciencedaily.com) Original source The discovery of a hybrid population of poplar trees in western Wyoming has provided insight into how natural hybridization informs the evolution of many plant species, according to researchers. They also said their discovery suggests that genetic exchange between species may be critical for adaptation to environmental change.
Published Scientists use machine learning to predict diversity of tree species in forests
(via sciencedaily.com) Original source Researchers used machine learning to generate highly detailed maps of over 100 million individual trees from 24 sites across the U.S. These maps provide information about individual tree species and conditions, which can greatly aid conservation efforts and other ecological projects.
Published Sun-like stars found orbiting hidden companions
(via sciencedaily.com) Original source Astronomers have uncovered what appear to be 21 neutron stars in orbit around stars like our Sun. The discovery is surprising because it is not clear how a star that exploded winds up next to a star like our Sun.
Published JWST unveils stunning ejecta and CO structures in Cassiopeia A's young supernova
(via sciencedaily.com) Original source Researchers announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse supernova in the Milky Way provide insights into the conditions that lead to the formation and destruction of molecules and dust within supernova ejecta. The study's findings change our understanding of dust formation in the early universe in the galaxies detected by JWST 300 million years after the Big Bang.
