Published Moths are more efficient pollinators than bees, shows new research
(via sciencedaily.com) Moths are more efficient pollinators at night than day-flying pollinators such as bees, finds new research.
Published Energy-efficient and customizable inorganic membranes for a cleaner future
(via sciencedaily.com) A team of researchers has developed a revolutionary technique for producing ultrathin inorganic membranes. These inorganic membranes are not just energy-efficient but also highly customizable for different applications, such as filtration, separation, energy conversion, catalysis and sensing. This ground-breaking achievement could potentially revolutionize the way many industries operate for greater sustainability.
Published How whale shark rhodopsin evolved to see, in the deep blue sea
(via sciencedaily.com) A group of researchers discovered that the rhodopsin -- a protein in the eye that detects light -- of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions -- one of which is counterintuitively associated with congenital stationary night blindness in humans -- aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.
Published Revolutionary battery technology to boost EV range 10-fold or more
(via sciencedaily.com) A team develops layering-charged, polymer-based stable high-capacity anode material.
Published Conserving wildlife can help mitigate climate change
(via sciencedaily.com) Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.
Published Turtles and crocodiles with unique characteristics are more likely to go extinct
(via sciencedaily.com) New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.
Published Research into birds killed in window collisions reveals their microbiomes
(via sciencedaily.com) Researchers collected the bodies of birds that crashed into buildings while migrating, and used these specimens to learn about the relationship between birds and the microbes living in their guts -- which appears to be wildly different from mammals and their microbiomes.
Published Eco-efficient cement could pave the way to a greener future
(via sciencedaily.com) Scientists develop process to remove toxic heavy metals from coal fly ash, making for greener, stronger concrete.
Published Highly charged ions melt nano gold nuggets
(via sciencedaily.com) Original source Shooting ions is very different from shooting a gun: By firing highly charged ions onto tiny gold structures, these structures can be modified in technologically interesting ways. Surprisingly, the key is not the force of impact, but the electric charge of the projectiles.
Published Climate change threatens lemurs on Madagascar
(via sciencedaily.com) Even supposedly adaptable mammal species face increased risk of extinction.
Published Epigenetic fingerprint as proof of origin for chicken, shrimp and salmon
(via sciencedaily.com) Free-range organic chicken or factory farming? Scientists have developed a new detection method that can reveal such differences in husbandry. The so-called epigenetic method is based on the analysis of the characteristic patterns of chemical markers on the genome of the animals.
Published The powerhouse of the future: Artificial cells
(via sciencedaily.com) Researchers identify the most promising advancements and greatest challenges of artificial mitochondria and chloroplasts. The team describes the components required to construct synthetic mitochondria and chloroplasts and identifies proteins as the most important aspects for molecular rotary machinery, proton transport, and ATP production. The authors believe it is important to create artificial cells with biologically realistic energy-generation methods that mimic natural processes; replicating the entire cell could lead to future biomaterials.
Published First silicon integrated ECRAM for a practical AI accelerator
(via sciencedaily.com) The transformative changes brought by deep learning and artificial intelligence are accompanied by immense costs. For example, OpenAI's ChatGPT algorithm costs at least $100,000 every day to operate. This could be reduced with accelerators, or computer hardware designed to efficiently perform the specific operations of deep learning. However, such a device is only viable if it can be integrated with mainstream silicon-based computing hardware on the material level.
Published Rare beetle, rediscovered after 55 years, named in honor of Jerry Brown
(via sciencedaily.com) While sampling for insects on former California Gov. Jerry Brown's ranch, a University of California, Berkeley, entomologist collected a rare species of beetle that had never been named or described -- and which, according to records, had not been observed by scientists in over 55 years. The new species will be named Bembidion brownorum, in honor of Jerry Brown and his wife, Anne Brown.
Published Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells
(via sciencedaily.com) Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.
Published More predictable renewable energy could lower costs
(via sciencedaily.com) Lower electricity costs for consumers and more reliable clean energy could be some of the benefits of a new study by researchers who have examined how predictable solar or wind energy generation is and the impact of it on profits in the electricity market.
Published AI 'brain' created from core materials for OLED TVs
(via sciencedaily.com) A research team develops semiconductor devices for high-performance AI operations by applying IGZO materials widely used in OLED displays.
Published Climate change threatens global fisheries
(via sciencedaily.com) The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.
Published Visualizing spatial distribution of electric properties at microscales with liquid crystal droplets
(via sciencedaily.com) Existing sensor probes for microelectrical devices can measure only their average electric properties, providing no information on their spatial distribution. Liquid crystal droplets (LCDs) -- microscopic droplets of soft matter that respond to electric field -- are promising in this regard. Accordingly, researchers recently visualized the electric field and electrostatic energy distribution of microstructured electrodes by recording the motion of LCDs under an applied voltage, making for high detection accuracy and spatial resolution.
Published Optical switching at record speeds opens door for ultrafast, light-based electronics and computers
(via sciencedaily.com) Imagine a home computer operating 1 million times faster than the most expensive hardware on the market. Now, imagine that being the industry standard. Physicists hope to pave the way for that reality.
