Published Spatial patterns in distribution of galaxies
(via sciencedaily.com) In an unlikely pairing, a chemist and an astrophysicist applied the tools of statistical mechanics to find similarities in spatial patterns across length scales.
Published Study shows how biodiversity of coral reefs around the world changes with depth
(via sciencedaily.com) Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.
Published Minke whales are as small as a lunge-feeding baleen whale can be
(via sciencedaily.com) A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.
Published Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems
(via sciencedaily.com) An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.
Published Sea temperatures control the distributions of European marine fish
(via sciencedaily.com) An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.
Published Unprecedented increase in ocean plastic since 2005 revealed by four decades of global analysis
(via sciencedaily.com) A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a new study.
Published Major North American oil source yields clues to one of earth's deadliest mass extinctions
(via sciencedaily.com) Geologists studying the Bakken Shale Formation discovered a critical kill mechanism behind a series of extinctions some 350 million years ago.
Published ALMA traces history of water in planet formation back to the interstellar medium
(via sciencedaily.com) Observations of water in the disk forming around protostar V883 Ori have unlocked clues about the formation of comets and planetesimals in our own solar system.
Published Paleontologists flip the script on anemone fossils
(via sciencedaily.com) Billions of sea anemones adorn the bottom of the Earth's oceans -- yet they are among the rarest of fossils because their squishy bodies lack easily fossilized hard parts. Now a team of paleontologists has discovered that countless sea anemone fossils have been hiding in plain sight for nearly 50 years. It turns out that fossils long-interpreted as jellyfish were anemones. To do so, a team of scientists has simply turned the ancient animals upside down.
Published Does current shellfish anti-predator gear curb 'crunching' rays?
(via sciencedaily.com) It's not just humans who enjoy eating shellfish, so do marine rays. They like to 'crunch' on clams, which can sometimes take a big bite out of clammers' profits. Using aerial and underwater videos, researchers assessed the ability of the whitespotted eagle ray to interact with clams housed within a variety anti-predator materials. Whitespotted eagle rays have strong jaws, plate-like teeth and nimble pectoral fins, which make them formidable and highly maneuverable predators of clams.
Published The planet that could end life on Earth
(via sciencedaily.com) A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a recent experiment.
Published Mineral particles and their role in oxygenating the Earth's atmosphere
(via sciencedaily.com) Mineral particles played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, according to new research.
Published Can artificial intelligence help find life on Mars or icy worlds?
(via sciencedaily.com) Researchers have mapped the sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano. Then they trained a machine learning model to recognize the patterns and rules associated with their distributions so it could learn to predict and find those same distributions in data on which it was not trained. In this case, by combining statistical ecology with AI/ML, the scientists could locate and detect biosignatures up to 87.5 percent of the time and decrease the area needed for search by up to 97 percent.
Published Toothed whales catch food in the deep using vocal fry
(via sciencedaily.com) Toothed whales, such as dolphins, killer whales and sperm whales communicate and catch food exclusively with sound. Now researchers have for the first time found they evolved a new sound source in their nose that is functionally the same as the human larynx.
Published Resurrected supernova provides missing link
(via sciencedaily.com) Astronomers have discovered a supernova exhibiting unprecedented rebrightening at millimeter wavelengths, providing an intermediate case between two types of supernovae: those of solitary stars and those in close-binary systems.
Published Hansel and Gretel's breadcrumb trick inspires robotic exploration of caves on Mars and beyond
(via sciencedaily.com) Future space missions likely will send robots to scout out underground habitats for astronauts. Engineers have now developed a system that would enable autonomous vehicles to explore caves, lava tubes and even oceans on other worlds on their own.
Published Ultracool dwarf binary stars break records
(via sciencedaily.com) Astrophysicists have discovered the tightest ultracool dwarf binary system ever observed. The two stars are so close that it takes them less than one Earth day to revolve around each other. In other words, each star's 'year' lasts just 17 hours.
Published Prehistoric sea monster may have been shorter, stouter, than once believed
(via sciencedaily.com) A big fish story? Maybe so: The greatest sea monster of the Devonian Period (Dunkleosteus terrelli) may be getting downsized. A new article contents that the famous sea monster of the Age of Fishes may not have neared 30-feet in length, as long believed, but topped off at maybe 13 feet. The new assertion brings attention to a famously fierce looking armored fish from 360 million years ago -- and maybe a new debate.
Published Coral-friendly sunscreen provides better UV protection than existing options
(via sciencedaily.com) Researchers have developed a prototype for coral-reef-friendly sunscreens by using polymerization to create large molecules that still block UV radiation but are too big to penetrate our skin, coral, and algae. The polymeric UV filter was more effective at preventing sunburn in mice than existing sunscreens.
Published Centuries of whaling data highlight likely climate change effect
(via sciencedaily.com) Centuries-old whaling records show how southern right whales are altering their feeding habits.
