Published Improved mangrove conservation could yield cash, carbon, coastal benefits
(via sciencedaily.com) Original source A shift in the way we think about the benefits mangroves provide to coastal regions could yield significant economic and biodiversity gains and protect millions from flooding, research has revealed.
Published Viruses dynamic and changing after dry soils are watered
(via sciencedaily.com) Original source Viruses in soil may not be as destructive to bacteria as once thought and could instead act like lawnmowers, culling older cells and giving space for new growth, according to research.
Published Study on mysterious Amazon porcupine can help its protection
(via sciencedaily.com) Original source A recent study sheds new light on the elusive Roosmalens' dwarf porcupine, a poorly understood neotropical species. After 22 years of relative obscurity, this research uncovers vital information about its distribution, phylogenetics, and potential conservation threats, not only revealing its endemic presence in the Madeira biogeographical province but also expanding its known range in the southern Amazon.
Published Colliding neutron stars provide a new way to measure the expansion of the Universe
(via sciencedaily.com) Original source In recent years, astronomy has seen itself in a bit of crisis: Although we know that the Universe expands, and although we know approximately how fast, the two primary ways to measure this expansion do not agree. Now astrophysicists suggest a novel method which may help resolve this tension.
Published Climate and human land use both play roles in Pacific island wildfires past and present
(via sciencedaily.com) Original source It’s long been understood that human settlement contributes to conditions that make Pacific Islands more susceptible to wildfires, such as the devastating Aug. 8 event that destroyed the Maui community of Lahaina. But a new study from fire scientist shows that climate is an undervalued part of the equation.
Published Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova
(via sciencedaily.com) Original source A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers new insight into what happens in the final year prior to a star's death and explosion.
Published Important additional driver of insect decline identified: Weather explains the decline and rise of insect biomass over 34 years
(via sciencedaily.com) Original source Combinations of unfavorable weather conditions over several years can cause a decline in insect biomass.
Published Down goes antimatter! Gravity's effect on matter's elusive twin is revealed
(via sciencedaily.com) For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.
Published New proof for black hole spin
(via sciencedaily.com) Original source The supermassive black hole at the heart of galaxy M87, made famous by the first picture of a black hole shadow, has yielded another first: the jet shooting out from the black hole has been confirmed to wobble, providing direct proof that the black hole is spinning.
Published Protecting lands slows biodiversity loss among vertebrates by five times
(via sciencedaily.com) Original source Protecting large swaths of Earth's land can help stem the tide of biodiversity loss -- especially when those protected areas are in less disturbed landscapes and in countries with effective national governance. A new study looked at how amphibians, reptiles, mammals and birds fared in protected versus unprotected areas worldwide. Vertebrate abundance decreased five times more slowly inside protected areas, offering much-needed support for the United Nations' '30 by 30' conservation initiative.
Published How to save plants from climate change? Just ask them
(via sciencedaily.com) Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for each species. A new study identified a range of characteristics from more than 100 types of plants that can be analyzed to determine each species' preferred temperature and rainfall amount.
Published New insights into the atmosphere and star of an exoplanet
(via sciencedaily.com) A new study of the intriguing TRAPPIST-1 exoplanetary system has demonstrated the complex interaction between the activity of the system's star and its planetary features.
Published Theories about the natural world may need to change to reflect human impact
(via sciencedaily.com) New research has validated at scale, one of the theories that has underpinned ecology for over half a century. In doing so, the findings raise further questions about whether models should be revised to capture human impacts on natural systems.
Published Hidden supermassive black holes reveal their secrets through radio signals
(via sciencedaily.com) Astronomers have found a striking link between the amount of dust surrounding a supermassive black hole and the strength of the radio emission produced in extremely bright galaxies.
Published Despite being properly treated and highly diluted, wastewater still impacts on the river ecosystem
(via sciencedaily.com) Original source An experiment using water from a large wastewater treatment plant has shown that this water continues to affect river diversity and the trophic web (food web) despite being properly treated and highly diluted before discharge. The study shows that the limits currently in place and the procedures used to treat wastewater may not be sufficient to protect the natural properties of food webs.
Published By air, rain and land: How microbes return after a wildfire
(via sciencedaily.com) Ecological disturbances like wildfires disrupt microbial communities. Researchers found that dispersal played a pivotal role in re-establishing surface-level communities.
Published Astronomers discover newborn galaxies with the James Webb Space Telescope
(via sciencedaily.com) With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the Universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed. But for the first time we now see signs that this relation between the amount of stars and elements does not hold for the earliest galaxies. The reason is likely that these galaxies simply are in the process of being created, and have not yet had the time to create the heavy elements.
Published Astronomers find abundance of Milky Way-like Galaxies in early Universe, rewriting cosmic evolution theories
(via sciencedaily.com) Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to new research.
Published Carbon source found on surface of Jupiter's moon Europa
(via sciencedaily.com) Astronomers using data from NASA's James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Europa.
Published Shh! Quiet cables set to help reveal rare physics events
(via sciencedaily.com) Newly developed ultra-low radiation cables reduce background noise for neutrino and dark matter detectors.
