Published Opening a window on the brain
(via sciencedaily.com) Original source Researchers have introduced a new method for in vivo brain imaging, enabling large-scale and long-term observation of neuronal structures and activities in awake mice. This method is called the 'nanosheet incorporated into light-curable resin' (NIRE) method, and it uses fluoropolymer nanosheets covered with light-curable resin to create larger cranial windows.
Published A key to the future of robots could be hiding in liquid crystals
(via sciencedaily.com) Original source Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital watches. The findings are a simple and inexpensive way to manipulate the molecular properties of liquid crystals with light exposure.
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 Photosynthetic secrets come to light
(via sciencedaily.com) Original source Secrets of photosynthesis have been discovered at atomic level, shedding important new light on this plant super-power that greened the earth more than a billion years ago.
Published Network of quantum sensors boosts precision
(via sciencedaily.com) Original source Quantum sensor technology promises even more precise measurements of physical quantities. A team has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.
Published A model for the evolution of intelligence
(via sciencedaily.com) Original source When certain species of wild birds and primates discover new ways of finding food in the wild, it can serve to measure their flexibility and intelligence. In the largest experimental study ever conducted on this topic, researchers have shown that foraging problems requiring overcoming obstacles, such as removing the lid off a container of food, are the only predictors of brain size and innovative behavior in the wild.
Published Cost of direct air carbon capture to remain higher than hoped
(via sciencedaily.com) Original source Researchers estimate the cost of removing 1 ton of CO2 from the air in the year 2050 to be between 230 and 540 US dollars to remove 1 ton. This is twice as high as previous estimates. The researchers compared the potential costs of three technologies that are already in use. From today's perspective, none of these technologies has clear advantages over the others in terms of potential costs. All three technologies should therefore be further developed, say the researchers.
Published Researchers use liquid crystals to control polarization inside laser-written waveguides
(via sciencedaily.com) Original source Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable electro-optical control of polarization, which could open new possibilities for chip-based devices and complex photonic circuits based on femtosecond-written waveguides.
Published Unraveling the mystery of chiton visual systems
(via sciencedaily.com) Original source You'd probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if it's one of the species with eyes dotting its platemail shell.
Published Study determines the original orientations of rocks drilled on Mars
(via sciencedaily.com) Original source Geologists determined the original orientation of many of the Mars bedrock samples collected by the Perseverance rover. The findings can give scientists clues to the conditions in which the rocks originally formed.
Published Tests show high-temperature superconducting magnets are ready for fusion
(via sciencedaily.com) Original source A comprehensive study of high-temperature superconducting magnets confirms they meet requirements for an economic, compact fusion power plant.
Published Firearm ownership is correlated with elevated lead levels in children, study finds
(via sciencedaily.com) Original source Childhood lead exposure, primarily from paint and water, is a significant health concern in the United States, but a new study has identified a surprising additional source of lead exposure that may disproportionately harm children: firearms. A team found an association between household firearm ownership and elevated lead levels in children's blood in 44 states, even when controlling for other major lead exposure sources.
Published Geologists explore the hidden history of Colorado's Spanish Peaks
(via sciencedaily.com) Original source A team has collected dozens of samples from across southeastern Colorado, and their results could help to answer an enduring mystery: What made Colorado's High Plains so high?
Published Beyond the ink: Painting with physics
(via sciencedaily.com) Original source Falling from the tip of a brush suspended in mid-air, an ink droplet touches a painted surface and blossoms into a masterpiece of ever-changing beauty. It weaves a tapestry of intricate, evolving patterns. Some of them resemble branching snowflakes, thunderbolts or neurons, whispering the unique expression of the artist's vision.
Published In wake of powerful cyclone, remarkable recovery of Pacific island's forests
(via sciencedaily.com) Original source After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research showed the resilience of the island's forests.
Published 2020 extreme weather event that brought fires and snow to western US
(via sciencedaily.com) Original source The same weather system that led to the spread of the devastating Labor Day wildfires in 2020 brought record-breaking cold and early-season snowfall to parts of the Rocky Mountains. Now, new research is shedding light on the meteorology behind what happened and the impacts of such an extreme weather event.
Published Orcas demonstrating they no longer need to hunt in packs to take down the great white shark
(via sciencedaily.com) Original source An orca (killer whale) has been observed, for the first-ever time, individually consuming a great white shark -- and within just two minutes.
Published Evolution-capable AI promotes green hydrogen production using more abundant chemical elements
(via sciencedaily.com) Original source A research team has developed an AI technique capable of expediting the identification of materials with desirable characteristics. Using this technique, the team was able to discover high-performance water electrolyzer electrode materials free of platinum-group elements -- substances previously thought to be indispensable in water electrolysis. These materials may be used to reduce the cost of large-scale production of green hydrogen -- a next-generation energy source.
Published Researchers create coating solution for safer food storage
(via sciencedaily.com) Original source Galvanized steel containers and surfaces are used for harvested produce because of their durability, strength and lower cost compared to stainless steel. However, bacteria residing in storage containers can cause corrosion. The new coating will reduce corrosion by at least 70 percent, researchers say.
Published Study results show 25% of pregnant people are not getting enough omega-3 fatty acids from their diet or dietary supplements
(via sciencedaily.com) Original source Results from a new US nationwide cohort study show that, despite strong recommendations in favor of consuming omega-3 fatty acids for optimal pregnancy outcomes and offspring health, 25% of participants reported rarely, or never eating fish during pregnancy, with fewer taking omega-3 supplements.
