Published Reptile roadkill reveals new threat to endangered lizard species
(via sciencedaily.com) Original source The chance sighting of a dead snake beside a sandy track in remote Western Australia, and the investigation of its stomach contents, has led researchers to record the first known instance of a spotted mulga snake consuming a pygmy spiny-tailed skink, raising concerns for a similar-looking, endangered lizard species.
Published New study reveals insight into which animals are most vulnerable to extinction due to climate change
(via sciencedaily.com) Original source In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
Published Loss of nature costs more than previously estimated
(via sciencedaily.com) Original source Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.
Published Marine algae implants could boost crop yields
(via sciencedaily.com) Original source Scientists have discovered the gene that enables marine algae to make a unique type of chlorophyll. They successfully implanted this gene in a land plant, paving the way for better crop yields on less land.
Published Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows
(via sciencedaily.com) Original source The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
Published Invasive plant time bombs: A hidden ecological threat
(via sciencedaily.com) Original source Invasive plants can stay dormant for decades or even centuries before rapidly expanding and wreaking ecological havoc, finds a new study.
Published Fossils of giant sea lizard with dagger-like teeth show how our oceans have fundamentally changed since the dinosaur era
(via sciencedaily.com) Original source Fossils of a strange new species of marine lizard with dagger-like teeth that lived 66 million years ago, show a dramatically more biodiverse ocean ecosystem to what we see today.
Published Plant Lavender, Marjoram and Ivy on your green wall to clean up the air
(via sciencedaily.com) Original source Green walls can strip pollution from the air -- and some plants do it better than others, according to new research. Researchers planted 10 species on a custom-built 1.4m green wall.
Published An evolutionary mystery 125 million years in the making
(via sciencedaily.com) Original source Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.
Published New dressing robot can 'mimic' the actions of care-workers
(via sciencedaily.com) Original source Scientists have developed a new robot that can 'mimic' the two-handed movements of care-workers as they dress an individual.
Published AI outperforms humans in standardized tests of creative potential
(via sciencedaily.com) Original source In a recent study, 151 human participants were pitted against ChatGPT-4 in three tests designed to measure divergent thinking, which is considered to be an indicator of creative thought.
Published Genetic research revealed several new fern species in tropical America
(via sciencedaily.com) Original source Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, 18 of which have now been given official names and species descriptions.
Published A new plant's name that tells a story
(via sciencedaily.com) Original source A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years.
Published Older African elephants will be most severely affected by the changing climate
(via sciencedaily.com) Original source Older elephants in East Africa will be most severely impacted by climate change, threatening the long-term survival of this vulnerable African mammal, according to a new study.
Published Avian influenza virus is adapting to spread to marine mammals
(via sciencedaily.com) Original source Avian influenza virus H5N1 has adapted to spread between birds and marine mammals, finds a new study.
Published Counting rays: Aerial surveys reveal ample populations in Southeast Florida
(via sciencedaily.com) Original source A unique long-term study quantified the abundance of whitespotted eagle and giant manta rays in Southeast Florida. Researchers conducted 120 survey flights between 2014 and 2021 from Miami north to the Jupiter Inlet. One or both species were seen on nearly every flight and both populations appear to be stable in the region. The giant manta rays were more abundant in the south and the whitespotted eagle rays were found all along the coast. Neither species seems to be deterred by the greater human population density in Fort Lauderdale/Miami.
Published Extinctions could result as fish change foraging behavior in response to rising temperatures
(via sciencedaily.com) Original source Fish species respond to temperature increases by going after more readily available prey. Models suggest this behavior could lead to more extinctions.
Published A novel method for easy and quick fabrication of biomimetic robots with life-like movement
(via sciencedaily.com) Original source Ultraviolet-laser processing is a promising technique for developing intricate microstructures, enabling complex alignment of muscle cells, required for building life-like biohybrid actuators. Compared to traditional complex methods, this innovative technique enables easy and quick fabrication of microstructures with intricate patterns for achieving different muscle cell arrangements, paving the way for biohybrid actuators capable of complex, flexible movements.
Published Common plant could help reduce food insecurity
(via sciencedaily.com) Original source An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air -- making it a valuable green fertilizer -- and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study suggests.
Published Biomolecular condensates -- regulatory hubs for plant iron supply
(via sciencedaily.com) Original source Iron is a micronutrient for plants. Biologists now show that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light -- an important signal for plant growth. They found that the initially homogeneously distributed proteins relocated together into 'biomolecular condensates' in the cell nucleus shortly after this exposure.
