Published Pioneering research sheds new light on the origins and composition of planet Mars
(via sciencedaily.com) Original source A new study has uncovered intriguing insights into the liquid core at the centre of Mars, furthering understanding of the planet's formation and evolution.
Published Vaccine printer could help vaccines reach more people
(via sciencedaily.com) Original source Researchers have designed a tabletop-sized vaccine printer that could be scaled up to produce hundreds of vaccine doses in a day and deployed anywhere vaccines are needed. The vaccine doses are contained within microneedle patches that can be stored long-term at room temperature and applied to the skin, avoiding the need for injections.
Published Making better measurements of the composition of galaxies
(via sciencedaily.com) Original source A study using data from telescopes on Earth and in the sky resolves a problem plaguing astronomers working in the infrared and could help make better observations of the composition of the universe with the James Webb Space Telescope and other instruments.
Published Cheaper method for making woven displays and smart fabrics -- of any size or shape
(via sciencedaily.com) Original source Researchers have developed next-generation smart textiles -- incorporating LEDs, sensors, energy harvesting, and storage -- that can be produced inexpensively, in any shape or size, using the same machines used to make the clothing we wear every day.
Published Nanowire networks learn and remember like a human brain
(via sciencedaily.com) Original source Scientists have demonstrated nanowire networks can exhibit both short- and long-term memory like the human brain.
Published Putting hydrogen on solid ground: Simulations with a machine learning model predict a new phase of solid hydrogen
(via sciencedaily.com) Original source Hydrogen, the most abundant element in the universe, is found everywhere from the dust filling most of outer space to the cores of stars to many substances here on Earth. This would be reason enough to study hydrogen, but its individual atoms are also the simplest of any element with just one proton and one electron.
Published Whales stop by Gold Coast bay for day spa fix with full body scrubs
(via sciencedaily.com) Original source A new Griffith University study has found that humpback whales will use sandy, shallow bay areas to 'roll' around in sandy substrates to remove dead skin cells on their return journeys south to cooler waters. Using data and footage collected from the tags, whales were observed performing full and side rolls in up to 49m water depth on the sea floor that was lined with fine sand or rubble.
Published ChatGPT is still no match for humans when it comes to accounting
(via sciencedaily.com) Original source ChatGPT faced off against students on accounting assessments. Students scored an overall average of 76.7%, compared to ChatGPT's score of 47.4%. On a 11.3% of questions, ChatGPT scored higher than the student average, doing particularly well on AIS and auditing. But the AI bot did worse on tax, financial, and managerial assessments, possibly because ChatGPT struggled with the mathematical processes required for the latter type.
Published Elephant seals drift off to sleep while diving far below the ocean surface
(via sciencedaily.com) Original source For the first time, scientists have recorded brain activity in a free-ranging, wild marine mammal, revealing the sleep habits of elephant seals during the months they spend at sea. The new findings show that while elephant seals may spend 10 hours a day sleeping on the beach during the breeding season, they average just 2 hours of sleep per day when they are at sea on months-long foraging trips. They sleep for about 10 minutes at a time during deep, 30-minute dives, often spiraling downward while fast asleep, and sometimes lying motionless on the seafloor.
Published Biologists discover bees to be brew masters of the insect world
(via sciencedaily.com) Original source Scientists have made a remarkable discovery about cellophane bees -- their microbiomes are some of the most fermentative known from the insect world. These bees, which are named for their use of cellophane-like materials to line their subterranean nests, are known for their fascinating behaviors and their important ecological roles as pollinators. Now, researchers have uncovered another aspect of their biology that makes them even more intriguing.
Published Cannabinoids give worms the munchies, too
(via sciencedaily.com) Original source Marijuana (cannabis) is well known for giving people the 'munchies.' Not only does it make people want to eat more, but it also makes them crave the tastiest, most high-calorie foods. Now a new study shows that well-studied nematode worms (C. elegans) react to those chemicals known as cannabinoids in precisely the same way.
Published AI system can generate novel proteins that meet structural design targets
(via sciencedaily.com) Original source A new machine-learning system can generate protein designs with certain structural features, and which do not exist in nature. These proteins could be utilized to make materials that have similar mechanical properties to existing materials, like polymers, but which would have a much smaller carbon footprint.
Published Chitin from consuming insects can help both gut microbiota and global health
(via sciencedaily.com) Original source Increased insect consumption by humans may be better for both gut health and planetary health. Chitin (kai'tin) and healthy fats from insects appear to contribute to healthy gut microbiota and are strong sources of protein and nutrients, according to a recent paper.
Published Quantum entanglement could make accelerometers and dark matter sensors more accurate
(via sciencedaily.com) Original source The 'spooky action at a distance' that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones.
Published X-ray analysis sheds new light on prehistoric predator's last meal
(via sciencedaily.com) Original source We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.
Published Rock, paper, scissors: Searching for stronger nonlocality using quantum computers
(via sciencedaily.com) Original source In the quantum world particles can instantaneously know about each other's state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.
Published Long-distance quantum teleportation enabled by multiplexed quantum memories
(via sciencedaily.com) Original source Researchers report having achieved quantum teleportation from a photon to a solid-state qubit over a distance of 1km, with a novel approach using multiplexed quantum memories.
Published Could this copycat black hole be a new type of star?
(via sciencedaily.com) Original source It looks like a black hole and bends light like a black hole, but it could actually be a new type of star. Though the mysterious object is a hypothetical mathematical construction, new simulations by Johns Hopkins researchers suggest there could be other celestial bodies in space hiding from even the best telescopes on Earth.
Published Tiny biobattery with 100-year shelf life runs on bacteria
(via sciencedaily.com) Original source A tiny biobattery that could still work after 100 years has been developed.
Published Metal-poor stars are more life-friendly
(via sciencedaily.com) Original source A star's chemical composition strongly influences the ultraviolet radiation it emits into space and thus the conditions for the emergence of life in its neighborhood.
