Published Blue tit population booms with moths on the menu
(via sciencedaily.com) Original source Researchers found that years when moth numbers were up resulted in increased population growth for the blue tit.
Published Gulls swap natural for urban habitats, machine-learning study finds
(via sciencedaily.com) Original source The study is the first of its kind to compile a three-year dataset using a citizen science-based, opportunistic research method to include a large sample of gulls and other sub-Arctic birds in urban Alaska. The study provides a current snapshot of the habitat shift to an urban landscape.
Published New research into hedgehogs injured by robotic lawn mowers discovers a significant but solvable animal welfare and conservation problem
(via sciencedaily.com) Original source Scientists analyzed 370 documented cases of hedgehogs being injured (cut) by electric gardening tools in Germany. Almost half of the hedgehogs found between June 2022 and September 2023 did not survive the injuries. The data reveal a serious animal welfare and conservation issue for these specially protected animals, as most hedgehogs were only found hours or even days after the accidents.
Published Don't blame the sharks: Why more hooked tarpon are being eaten
(via sciencedaily.com) Original source In wave-making research, a team of biologists has quantified the rate at which great hammerhead sharks are eating Atlantic tarpon hooked by anglers at Bahia Honda, Florida -- one of the prime tarpon fishing spots in the Florida Keys.
Published New sustainable method for creating organic semiconductors
(via sciencedaily.com) Original source Researchers have developed a new, more environmentally friendly way to create conductive inks for use in organic electronics such as solar cells, artificial neurons, and soft sensors. The findings pave the way for future sustainable technology.
Published Student discovers 200-million-year-old flying reptile
(via sciencedaily.com) Original source Gliding winged-reptiles were amongst the ancient crocodile residents of the Mendip Hills in Somerset, England, researchers at the have revealed.
Published Breakthrough research enhances stability and efficiency of perovskite solar cells
(via sciencedaily.com) Original source A research team has achieved remarkable advancements in the stability and efficiency of perovskite solar cells.
Published Knowing what dogs like to watch could help veterinarians assess their vision
(via sciencedaily.com) Original source A veterinary ophthalmologist wanted to determine factors, including age and vision, that influence a dog's interest in interacting with video content. Ultimately, the goal of the study, which launched two years ago, was to support development of more sensitive ways to assess canine vision -- something that has been sorely lacking in veterinary medicine. The study found that dogs are most engaged when watching videos that feature other animals.
Published For this beetle, 'date night' comes every other day
(via sciencedaily.com) Original source Life on Earth runs on a 24-hour cycle as the planet turns. Animals and plants have built-in circadian clocks that synchronize metabolism and behavior to this daily cycle. But one beetle is out of sync with the rest of nature. A new study looks at a beetle with a unique, 48-hour cycle.
Published Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird
(via sciencedaily.com) Original source The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.
Published Machine learning method speeds up discovery of green energy materials
(via sciencedaily.com) Original source Researchers have developed a framework that uses machine learning to accelerate the search for new proton-conducting materials, that could potentially improve the efficiency of hydrogen fuel cells.
Published Why animals shrink over time explained with new evolution theory
(via sciencedaily.com) Original source The new theoretical research proposes that animal size over time depends on two key ecological factors.
Published Efficiently moving urea out of polluted water is coming to reality
(via sciencedaily.com) Original source Researchers have developed a material to remove urea from water and potentially convert it into hydrogen gas. By building these materials of nickel and cobalt atoms with carefully tailored electronic structures, the group has unlocked the potential to enable these transition metal oxides and hydroxides to selectively oxidize urea in an electrochemical reaction. The team's findings could help use urea in waste streams to efficiently produce hydrogen fuel through the electrolysis process, and could be used to sequester urea from water, maintaining the long-term sustainability of ecological systems, and revolutionizing the water-energy nexus.
Published Rain can spoil a wolf spider's day, too
(via sciencedaily.com) Original source Researchers found that wolf spiders can't signal others or perceive danger from predators as easily on rain-soaked leaves compared to dry ones. Even communicating with would-be mates is harder after it rains.
Published Tiny AI-based bio-loggers revealing the interesting bits of a bird's day
(via sciencedaily.com) Original source Researchers have developed a bio-logger for seabirds that enables long-term observation of rare behaviors. The bio-logger employs low-power depth sensors and accelerometers to identify rare behavior using a light-weight outlier detection model and records the behavior in a 5-min video. Observations using the bio-loggers on Streaked Shearwaters revealed novel aspects of head-shaking and foraging strategies. This approach will enable a wider range of animal behaviors in various environments to be observed.
Published Surprise discovery: For most animals, sperm quality does not reduce with age
(via sciencedaily.com) Original source In humans, male fertility and sperm fitness decline with age, but scientists have made the surprising discovery that this pattern is not consistent in other animals. The team assessed the results of 379 studies which covered a wide range of animals, including mammals, insects, birds, and fish.
Published Artificial 'power plants' harness energy from wind and rain
(via sciencedaily.com) Original source Fake plants are moving into the 21st century! Researchers developed literal 'power plants' -- tiny, leaf-shaped generators that create electricity from a blowing breeze or falling raindrops. The team tested the energy harvesters by incorporating them into artificial plants.
Published Space solar power project ends first in-space mission with successes and lessons
(via sciencedaily.com) Original source A 10-month mission demonstrated three elements of the plan to beam solar power from space to Earth.
Published New technology for conducting deep-sea research on fragile organisms
(via sciencedaily.com) Original source Scientists have successfully demonstrated new technologies that can obtain preserved tissue and high-resolution 3D images within minutes of encountering some of the most fragile animals in the deep ocean.
Published Study reveals a reaction at the heart of many renewable energy technologies
(via sciencedaily.com) Original source Chemists have mapped how proton-coupled electron transfers happen at the surface of an electrode. Their results could help researchers design more efficient fuel cells, batteries, or other energy technologies.
