Published Moths are more efficient pollinators than bees, shows new research
(via sciencedaily.com) Moths are more efficient pollinators at night than day-flying pollinators such as bees, finds new research.
Published Conserving wildlife can help mitigate climate change
(via sciencedaily.com) Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.
Published Turtles and crocodiles with unique characteristics are more likely to go extinct
(via sciencedaily.com) New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.
Published Research into birds killed in window collisions reveals their microbiomes
(via sciencedaily.com) Researchers collected the bodies of birds that crashed into buildings while migrating, and used these specimens to learn about the relationship between birds and the microbes living in their guts -- which appears to be wildly different from mammals and their microbiomes.
Published Climate change threatens lemurs on Madagascar
(via sciencedaily.com) Even supposedly adaptable mammal species face increased risk of extinction.
Published Redness of Neptunian asteroids sheds light on early Solar System
(via sciencedaily.com) Asteroids sharing their orbits with the planet Neptune have been observed to exist in a broad spectrum of red color, implying the existence of two populations of asteroids in the region, according to a new study by an international team of researchers.
Published Epigenetic fingerprint as proof of origin for chicken, shrimp and salmon
(via sciencedaily.com) Free-range organic chicken or factory farming? Scientists have developed a new detection method that can reveal such differences in husbandry. The so-called epigenetic method is based on the analysis of the characteristic patterns of chemical markers on the genome of the animals.
Published JWST confirms giant planet atmospheres vary widely
(via sciencedaily.com) Astronomers have found the atmospheric compositions of giant planets out in the galaxy do not fit our own solar system trend.
Published Temperature of a rocky exoplanet measured
(via sciencedaily.com) An international team of researchers has used NASA's James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI). The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 450 degrees Fahrenheit) and suggests that it has no significant atmosphere.
Published Two meteorites are providing a detailed look into outer space
(via sciencedaily.com) If you've ever seen a shooting star, you might have seen a meteor on its way to Earth. Those that land here can be used to peek back in time, into the far corners of outer space or at the earliest building blocks of life. Scientists have conducted some of the most detailed analyses yet on the organic material of two meteorites.
Published Climate change threatens global fisheries
(via sciencedaily.com) The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.
Published Habitat will dictate whether ground beetles win or lose against climate change
(via sciencedaily.com) The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.
Published AI finds the first stars were not alone
(via sciencedaily.com) Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.
Published Babies or beauty? Ancient origin of how female butterflies invest
(via sciencedaily.com) When resources are scarce, most animals have to choose. A new study reveals an ancient origin to how female butterflies invest.
Published Sea otters killed by unusual parasite strain
(via sciencedaily.com) An unusually severe form of toxoplasmosis killed four sea otters and could pose a threat to other marine wildlife and humans, finds a new study.
Published Surprisingly simple explanation for the alien comet 'Oumuamua's weird orbit
(via sciencedaily.com) When the first interstellar comet ever seen in our solar system was discovered in 2017, one characteristic -- an unexplained acceleration away from the sun -- sparked wild speculation, including that it was an alien spacecraft. An astrochemist found a simpler explanation and tested it with an astronomer: in interstellar space, cosmic rays converted water to hydrogen in the comet's outer layers. Nearing the sun, outgassed hydrogen gave the tiny comet a kick.
Published Observing group-living animals with drones and computer vision
(via sciencedaily.com) New method to study the movement, behaviour, and environmental context of group-living animals using drones and computer vision.
Published Turn off porch light to aid caterpillars -- and safeguard backyard ecosystems
(via sciencedaily.com) Moderate levels of artificial light at night -- like the fixture illuminating your backyard -- bring more caterpillar predators and reduce the chance that these lepidoptera larvae grow up to become moths and serve as food for larger prey.
Published Researchers get to the 'bottom' of how beetles use their butts to stay hydrated
(via sciencedaily.com) Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.
Published New animal welfare scoring system could enable better-informed food and farming choices
(via sciencedaily.com) Scientists have come up with a system of measuring animal welfare that enables reliable comparison across different types of pig farming.
