Published The impacts of climate change on food production
(via sciencedaily.com) Original source A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.
Published Digging up good news for microbial studies
(via sciencedaily.com) Original source Findings indicate that soil stored under refrigerated or air-dried conditions can still retain the needed information for understanding microbial community composition and structure for many years.
Published Webb Telescope offers first glimpse of an exoplanet's interior
(via sciencedaily.com) Original source A surprisingly low amount of methane and a super-sized core hide within the cotton candy -- like planet WASP-107 b.
Published Cloudy waters causes African fish to develop bigger eyes
(via sciencedaily.com) Original source Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study.
Published Ukraine war caused migrating eagles to deviate from their usual flight plan, study finds
(via sciencedaily.com) Original source When migrating through Ukraine in 2022, Greater Spotted Eagles were exposed to multiple conflict events that altered their migratory course, according to a new study.
Published Modern plant enzyme partners with surprisingly ancient protein
(via sciencedaily.com) Original source Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls with significant impacts on the clean energy industry.
Published Scale matters in determining vulnerability of freshwater fish to climate changes
(via sciencedaily.com) Original source A team explored the influence the spatial extent of research -- the geographical coverage of data collected -- has on evaluating the sensitivity of different fish species to climate change.
Published Ancient arachnid from coal forests of America stands out for its spiny legs
(via sciencedaily.com) Original source The spiny legged 308-million-year-old arachnid Douglassarachne acanthopoda was discovered the famous Mazon Creek locality.
Published How did sabre-toothed tigers acquire their long upper canine teeth?
(via sciencedaily.com) Original source In a groundbreaking study an international team of scientists has investigated the evolutionary patterns behind the development of sabre teeth, with some unexpected results along the way.
Published From roots to resilience: investigating the vital role of microbes in coastal plant health
(via sciencedaily.com) Original source Understanding how salt marsh grass stays healthy is of crucial ecological importance, and studying the ways bacteria interact with these plants is key. Thanks to recent advances in genomic technology, biologists have begun to reveal never-before-seen ecological processes.
Published Hubble views the dawn of a sun-like star
(via sciencedaily.com) Original source Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is made up of the variable star HP Tau, HP Tau G2, and HP Tau G3. HP Tau is known as a T Tauri star, a type of young variable star that hasn't begun nuclear fusion yet but is beginning to evolve into a hydrogen-fueled star similar to our Sun.
Published Robotic 'SuperLimbs' could help moonwalkers recover from falls
(via sciencedaily.com) Original source SuperLimbs, a system of wearable robotic limbs, can physically support an astronaut and lift them back on their feet after a fall, helping them conserve energy for other essential tasks.
Published Access to gardens and citizen science helps encourage conservation among children, study shows
(via sciencedaily.com) Original source Access to gardens and citizen science projects at school can help promote pro-conservation behaviour among pupils, a new study shows.
Published Scientists want to know how the smells of nature benefit our health
(via sciencedaily.com) Original source Spending time in nature is good for us. And knowing more about nature's effects on our bodies could not only help our well-being, but could also improve how we care for land, preserve ecosystems and design cities, homes and parks. Many studies have focused on how seeing nature affects us. A team of scientists from around the world wants to understand what the nose knows. They are calling for more research into how odors and scents from natural settings impact our health and well-being.
Published Bees and butterflies on the decline in western and southern North America
(via sciencedaily.com) Original source Bee and butterfly populations are in decline in major regions of North America due to ongoing environmental change, and significant gaps in pollinator research limit our ability to protect these species, according to a new study.
Published Summers warm up faster than winters, fossil shells from Antwerp show
(via sciencedaily.com) Original source In a warmer climate, summers warm much faster than winters, according to research into fossil shells. With this knowledge we can better map the consequences of current global warming in the North Sea area.
Published Detection of an Earth-sized exoplanet orbiting the ultracool dwarf star SPECULOOS-3
(via sciencedaily.com) Original source Astronomers have just discovered a new Earth-sized exoplanet around SPECULOOS-3, an 'ultracool dwarf' star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After the famous TRAPPIST-1, SPECULOOS 3 is the second planetary system discovered around this type of star.
Published Climate change is most prominent threat to pollinators
(via sciencedaily.com) Original source A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.
Published First 'warm-blooded' dinosaurs may have emerged 180 million years ago
(via sciencedaily.com) Original source The ability to regulate body temperature, a trait all mammals and birds have today, may have evolved among some dinosaurs early in the Jurassic period about 180 million years ago. The new study looked at the spread of dinosaurs across different climates on Earth throughout the Mesozoic Era (the dinosaur era lasting from 230 to 66 million years ago), drawing on 1,000 fossils, climate models and the geography of the period, and dinosaurs' evolutionary trees.
Published How wildfires change soil chemistry
(via sciencedaily.com) Original source Severe wildfires can drive chemical changes in soil that affect ecosystem recovery and risks to human health. A new study finds broader surveillance and modeling of these changes could inform strategies for protecting lives, property and natural resources, and managing wildlife.
