Published Investigators examine shifts in coral microbiome under hypoxia
(via sciencedaily.com) Original source A new study provides the first characterization of the coral microbiome under hypoxia, insufficient oxygen in the water.
Published Giant planets cast a deadly pall
(via sciencedaily.com) Original source Giant gas planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other stars. New studies show, in some planetary systems, the giants tend to kick smaller planets out of orbit and wreak havoc on their climates.
Published Amazon deforestation linked to long distance climate warming
(via sciencedaily.com) Original source Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study. The research suggests that tropical forests play a critical role in cooling the land surface -- and that effect can play out over considerable distances.
Published 'Robin Hood' approach for tracking biodiversity
(via sciencedaily.com) Original source Researchers have developed a framework that can help scientists understand trends in biodiversity by using data from well-characterized species to provide insights on data-deficient species. The framework provides a how-to guide for researchers and practitioners to implement.
Published First detection of heavy element from star merger
(via sciencedaily.com) Original source A team of scientists has used multiple space and ground-based telescopes to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion's aftermath.
Published UK air pollution regulations will reduce deaths, but do little to protect ecosystems
(via sciencedaily.com) Original source Existing air pollution regulations will reduce thousands of premature adult deaths in the UK, but even the most effective technically feasible actions, which will save thousands more lives, will do little to protect the country's sensitive ecosystems, find researchers.
Published Raining cats and dogs: Global precipitation patterns a driver for animal diversity
(via sciencedaily.com) Original source A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.
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 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 Unearthing the ecological impacts of cicada emergences on North American forests
(via sciencedaily.com) Original source New research unveils the cascading effects of periodical cicada emergence events on forest ecosystems ahead of an historic convergence of broods set to emerge spring of 2024.
Published Scientists discover deepest known evidence of coral reef bleaching
(via sciencedaily.com) Original source Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
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 New mollusk and crustacean species in symbiosis with worms in dead coral rocks
(via sciencedaily.com) Original source The symbiotic communities of invertebrates in dead coral gravel on the shallow, warm-temperate coast of the Kii Peninsula in western Japan. New bivalve species and sideswimmer have been found to live communally with the greenish Bonellia spoonworm. Live-in symbionts share the burrows of other organisms in sand and mud on the seabed. However, studies on burrow niches in rigid substrates, such as rocks on the seabed, have been scarce.
Published Subalpine forests in the Northern Rockies are fire resilient--for now
(via sciencedaily.com) Original source Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.
Published Scientists, philosophers identify nature's missing evolutionary law
(via sciencedaily.com) Original source A new article describes 'a missing law of nature,' recognizing for the first time an important norm within the natural world's workings. In essence, the new law states that complex natural systems evolve to states of greater patterning, diversity, and complexity. In other words, evolution is not limited to life on Earth, it also occurs in other massively complex systems, from planets and stars to atoms, minerals, and more.
Published Climate change coping mechanism discovered in humble algae
(via sciencedaily.com) Original source One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.
Published Wildfires threaten environmental gains in climate-crucial Amazon
(via sciencedaily.com) Original source Despite steps toward decreasing deforestation, uncontrolled wildfires are threatening environmental gains in Brazilian Amazonia, one of the world's most critical carbon sinks and a region of high biological and cultural diversity.
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 Using different flours for sourdough fosters different bacteria -- and flavors
(via sciencedaily.com) Original source A new study of the microbial ecosystem in sourdough finds that using different types of flour fosters distinct bacterial communities, and that these differences contribute to the variation of sourdough aromas and flavors.
Published Finding explanation for Milky Way's warp
(via sciencedaily.com) Original source Though scientists have long known through observational data that the Milky Way is warped and its edges are flared like a skirt, no one could explain why. Now, astronomers have performed the first calculations that fully explain this phenomenon, with compelling evidence pointing to the Milky Way's envelopment in an off-kilter halo of dark matter.
