Published Glimpse into the nanoworld: Microscope reveals tiniest cell processes
(via sciencedaily.com) Original source What does the inside of a cell really look like? In the past, standard microscopes were limited in how well they could answer this question. Now, researchers have succeeded in developing a microscope with resolutions better than five nanometers (five billionths of a meter). This is roughly equivalent to the width of a hair split into 10,000 strands.
Published Forever chemical pollution can now be tracked
(via sciencedaily.com) Original source Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.
Published Research challenges conventional wisdom on wet surface adhesion
(via sciencedaily.com) Original source Scientists overturned long-held assumptions in that finds water can be a help for adhesion. The implications of this research are particularly in biomedical applications such as bandages, health monitoring sensors for moist skin, and advanced adhesives that could replace sutures. The insights gained into leveraging surface roughness and material properties could revolutionize industries worth billions of dollars globally.
Published Monitoring of nature reserves via social media and deep learning
(via sciencedaily.com) Original source Researchers have created a deep learning method to analyze social media images taken within protected green spaces to gain insights on human activity distribution as a way to monitor the ecological impacts of these activities.
Published World's highest-performance superconducting wire segment
(via sciencedaily.com) Original source Researchers report that they have fabricated the world's highest-performing high-temperature superconducting wire segment while making the price-performance metric significantly more favorable.
Published Walking the walk, scientists develop motion-compatible brain scanner
(via sciencedaily.com) Original source An upright neuroimaging device developed by neuroscientists, physicists and engineers allows patients to move around while undergoing a brain scan.
Published Plants offer fruit to insects to disperse dust-like seeds
(via sciencedaily.com) Original source Fruit exist to invite animals to disperse the swallowed seeds. A research team found that plants targeting insects rather than birds or mammals for this service are more common than previously thought. These plants produce dust-like seeds and fruit suitable for the minute, ground-dwelling animals.
Published Dozing at the wheel? Not with these fatigue-detecting earbuds
(via sciencedaily.com) Original source To help protect drivers and machine operators from the dangers of drifting off, engineers have created prototype earbuds that can detect the signs of drowsiness in the brain. In a new study, the researchers show that their Ear EEG platform is sensitive enough to detect alpha waves, a pattern of brain activity that increases when you close your eyes or start to fall asleep.
Published Elephants on the move: Mapping connections across African landscapes
(via sciencedaily.com) Original source Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.
Published Living with a killer: How an unlikely mantis shrimp-clam association violates a biological principle
(via sciencedaily.com) Original source When clams gamble on living with a killer, sometimes their luck may run out, according to a new study.
Published Advanced chelators offer efficient and eco-friendly rare earth element recovery
(via sciencedaily.com) Original source The world is going to need a lot of weird metals in the coming years, according to chemistry professor. But he isn't talking about lithium, cobalt or even beryllium. He's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up.
Published Stacking molecules like plates improves organic solar device performance
(via sciencedaily.com) Original source Researchers found that how well light-converting molecules stack together in a solid is important for how well they convert light into electric current. A rigid molecule that stacked well showed excellent electricity generation in an organic solar cell and photocatalyst, easily outperforming a similar flexible molecule that did not stack well. This new way of improving the design of molecules could be used to pioneer the next generation of light-converting devices.
Published The race to discover biodiversity: 11 new marine species and a new platform for rapid species description
(via sciencedaily.com) Original source A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.
Published Soft gold enables connections between nerves and electronics
(via sciencedaily.com) Original source Gold does not readily lend itself to being turned into long, thin threads. But researchers have now managed to create gold nanowires and develop soft electrodes that can be connected to the nervous system. The electrodes are soft as nerves, stretchable and electrically conductive, and are projected to last for a long time in the body.
Published A new way of thinking about the economy could help protect the Amazon, and help its people thrive
(via sciencedaily.com) Original source To protect the Amazon and support the wellbeing of its people, its economy needs to shift from environmentally harmful production to a model built around the diversity of indigenous and rural communities, and standing forests.
Published First measurement of electron- and muon-neutrino interaction rates at the highest energy ever detected from an artificial source
(via sciencedaily.com) Original source Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe. To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector. This study marks a significant step for particle physics research.
Published New research sheds light on relationships between plants and insects in forest ecosystems
(via sciencedaily.com) Original source Researchers have published new findings on how leaf-eating insects affect forest ecosystems worldwide. Researchers are aware of how large herbivores cycle nutrients in forests. They know much less, however, about how leaf-eating insects impact forest carbon and nutrient cycling.
Published Combined effects of plastic pollution and seawater flooding amplify threats to coastal plant species
(via sciencedaily.com) Original source A new study highlights how a combination of environmental stressors -- namely plastic pollution and seawater flooding -- can increase the threats faced by plants in some of the planet's critical ecosystems. It showed that both stressors had some effects on the species tested, but being exposed to both microplastics and flooding together -- a threat likely to increase as a result of climate change and plastic use -- had a more pronounced impact on their resource allocation.
Published Flamingos don't preen more than other waterbirds
(via sciencedaily.com) Original source Despite their famously fancy feathers, flamingos don't spent more time preening than other waterbirds, new research shows.
Published Dopamine physiology in the brain unveiled through cutting-edge brain engineering
(via sciencedaily.com) Original source Researchers have discovered a new correlation between neural signaling in the brain and dopamine signaling in the striatum. The human brain requires fast neural signal processing in a short period of less than a second. Dopamine is known to have the strongest effect on brain neural signals, but the research team's newly developed 'optical neural chip-based multiple brain signal monitoring technology' shows that changes in dopamine signals within the physiological range do not affect brain neural signal processing.
