Much of the progress made in understanding the scope of bird deaths from building and window collisions has come as the result of citizen science, according to a newly published study. But the study also concludes that such grassroots efforts need more buy-in from government and industry, and better funding so they can keep a foot on the gas in their efforts to reduce bird-window collisions.
Researchers have developed a new 'camera' that sees the local disorder in materials. Its key feature is a variable shutter speed: because the disordered atomic clusters are moving, when the team used a slow shutter, the dynamic disorder blurred out, but when they used a fast shutter, they could see it. The method uses neutrons to measure atomic positions with a shutter speed of around one...
A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals....
Machine learning can be valuable in supporting sustainable development of biomass if it is applied across the entire lifecyle of biomass and biomass-derived products, according to a new study.
A new study has shown that bumblebees pick up new 'trends' in their behavior by watching and learning from other bees, and that one form of a behavior can spread rapidly through a colony even when a different version gets discovered.
The Phlegraean volcanic fields just west of Naples, Italy, are among the top eight emitters of volcanic carbon dioxide in the world. Since 2005, the Solfatara crater -- one of many circular depressions in the landscape left by a long history of eruptions --has been emitting increased volumes of gas. Today it emits 4,000-5,000 tons of carbon dioxide each day, equivalent to the emissions from...
Researchers describe a new manner of detecting microbial infection that intercepts pathogen-derived signals of growth to assess the relative threat of virulent bacteria. A nuclear hormone receptor in the nematode C. elegans senses a toxic metabolite produced by the bacterial pathogen Pseudomonas aeruginosa to activate innate immunity. These data reveal an ancient strategy that informs the origins...
Researchers reveal that cardiomyocytes and skeletal muscle cells replace their existing stock of ribosomes with a different type which can make physical contact with mitochondria, the batteries of the cells, and significantly boost the production of ATP. In the heart, the natural mechanism is triggered in response to myocardial infarction, as well as cardiac hypertrophy. The findings establish...
In analyses of genetic and area-level socioeconomic data for more than 260,000 individuals, researchers found an additive effect of genetic and socioeconomic risk on the prevalence of obesity and type 2 diabetes.
New research that may eventually enable far earlier autism diagnoses shows that typically developing infants perceive audio-video synchrony better than high-risk for autism infants.
Reducing the methylation of a key messenger RNA can promote migration of macrophages into the brain and ameliorate symptoms of Alzheimer's disease in a mouse model, according to a new study. The results illuminate one pathway for entrance of peripheral immune cells into the brain, and may provide a new target for treatment of Alzheimer's disease.
Researchers have successfully developed a blood test for anxiety. The test examines biomarkers that can help them objectively determine someone’s risk for developing anxiety, the severity of their current anxiety and which therapies would likely treat their anxiety the best.
A hormone called fibroblast growth factor 21 (FGF21) protects mice against ethanol-induced loss of balance and righting reflex, according to a new study.
Materials scientists describe in two papers how complex oxides can be used to create very energy-efficient magneto-electric spin-orbit (MESO) devices and memristive devices with reduced dimensions.
Researchers have created software and hardware for a 4D printer with applications in the biomedical field. In addition to 3D printing, this machine allows for controlling extra functions: programming the material's response so that shape-changing occurs under external magnetic field, or changes in its electric properties develops under mechanical deformation. This opens the door to the design of...
How long is the present? The answer, researchers suggest in a new study, depends on your heart. They found that our momentary perception of time is not continuous but may stretch or shrink with each heartbeat.
Researchers are adding to their list of consumer products that contain PFAS (per- and polyfluoroalkyl substances), a toxic class of fluorine compounds known as 'forever chemicals.' In a new study, fluorinated high-density polyethylene (HDPE) plastic containers -- used for household cleaners, pesticides, personal care products and, potentially, food packaging -- tested positive for PFAS.
Comparing the colors on pieces of ancient Peruvian pottery revealed that potters across the Wari empire all used the same rich black pigment: a sign of the empire's influence.
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...
Space travel has always tested the human body by the effects of the new conditions of altered gravity on biological systems. It has long been known that continuous exposure to microgravity conditions human physiology and causes effects that compromise muscular, sensory, endocrine and cardiovascular functions. But is it also risky to be exposed to altered gravity for short periods of time?
Astronomers and amateurs alike know the bigger the telescope, the more powerful the imaging capability. To keep the power but streamline one of the bulkier components, a research team created the first ultrathin, compact metalens telescope capable of imaging far-away objects, including the moon.
An artificial intelligence (AI) tool can accurately identify normal and abnormal chest X-rays in a clinical setting, according to a new study.
Scientists have developed a polymer coating that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles. The advance opens up a new approach to developing EV batteries that are more affordable and easy to manufacture.
Milutin Milankovitch hypothesized that the timing of glacial transitions has been controlled by the orbital parameters of the Earth, which suggests that there may be some predictability in the climate, a notoriously complex system. Now researchers propose a new paradigm to simplify the verification of the Milankovitch hypothesis. The new 'deterministic excitation paradigm' combines the physics...
