Published 3D bioprinting advances research on respiratory viruses



Researchers develop a microstructured 'artificial lung' model using bioprinting technology.
Published Imaging technique uncovers protein abnormality in motor neurone disease



Researchers have used a new technique to identify pathological abnormalities associated with motor neurone disease.
Published Artificial compound eye to revolutionize robotic vision at lower cost but higher sensitivity



A research team has recently developed a novel artificial compound eye system that is not only more cost-effective, but demonstrates a sensitivity at least twice that of existing market products in small areas. The system promises to revolutionize robotic vision, enhance robots' abilities in navigation, perception and decision-making, while promoting commercial application and further development in human-robot collaboration.
Published Breakthrough in molecular control: New bioinspired double helix with switchable chirality



The control of artificial double-helical structures, which are essential for the development of high-order molecular systems, remains difficult. In a new study, researchers have developed novel double-helical monometallofoldamers that exhibit controllable helicity inversion and chiral information transfer, in response to external stimuli. These monometallofoldamers can lead to novel artificial supramolecular systems for molecular information transmission, amplification, replication, and other exciting applications in various fields of technology.
Published Glimpse into the nanoworld: Microscope reveals tiniest cell processes



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 Individuals vary in how air pollution impacts their mood



Affective sensitivity to air pollution (ASAP) describes the extent to which affect, or mood, fluctuates in accordance with daily changes in air pollution, which can vary between individuals, according to a new study.
Published Forever chemical pollution can now be tracked



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 When mammoths roamed Vancouver Island



Mammoths, the massive pre-historic ice age cousins of the modern-day elephant, have always been understood to have inhabited parts of British Columbia, but the question of when has always been a bit woolly. Now, a new study has given scientists the clearest picture yet when the giant mammals roamed Vancouver Island.
Published Research challenges conventional wisdom on wet surface adhesion



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 World's highest-performance superconducting wire segment



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 Fishing is causing frightened fish to flee when they should flirt



Populations of squaretail grouper face an uncertain future as new research shows fishing that targets their spawning sites is causing males to be repeatedly scared away from their territories during their short mating meet-ups. By fleeing for safety, individuals are losing valuable time to catch the eye and court female fish.
Published Walking the walk, scientists develop motion-compatible brain scanner



An upright neuroimaging device developed by neuroscientists, physicists and engineers allows patients to move around while undergoing a brain scan.
Published Dozing at the wheel? Not with these fatigue-detecting earbuds



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 Advanced chelators offer efficient and eco-friendly rare earth element recovery



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



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 Soft gold enables connections between nerves and electronics



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 Carvings at ancient monument may be world's oldest calendars



Markings on a stone pillar at a 12,000 year-old archaeological site in Turkey likely represent the world's oldest solar calendar, created as a memorial to a devastating comet strike, experts suggest.
Published First measurement of electron- and muon-neutrino interaction rates at the highest energy ever detected from an artificial 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 Dopamine physiology in the brain unveiled through cutting-edge brain engineering



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.
Published Precise package delivery in cells?



Researchers have developed new real-time microscopy technology and successfully observed the behavior of 'motor proteins', which may hold the key to unraveling the efficient material transport strategy of cells.
