Published Solar batteries: New material makes it possible to simultaneously absorb light and store energy
(via sciencedaily.com) Researchers are making progress on the design of a solar battery made from an abundant, non-toxic and easily synthesized material composed of 2D carbon nitride.
Published Wormlike animals are first amphibians shown to pass microbes to their offspring
(via sciencedaily.com) Original source Caecilians are an illusive type of snakelike amphibian that live in aquatic and subterranean environments. In some species, mothers produce a special type of nutrient-rich skin that juveniles consume, similar to the way in which humans breastfeed their children. A new study shows this behavior passes on microbes to juvenile caecilians, inoculating them to jump-start a healthy microbiome.
Published Going the distance for better wireless charging
(via sciencedaily.com) Accounting for radiation loss is the key to efficient wireless power transfer over long distances.
Published Paleontologists identify two new species of sabertooth cat
(via sciencedaily.com) Original source Sabertooth cats make up a diverse group of long-toothed predators that roamed Africa around 6-7 million years ago, around the time that hominins -- the group that includes modern humans -- began to evolve. By examining one of the largest global Pliocene collections of fossils in Langebaanweg, north of Cape Town in South Africa, researchers present two new sabertooth species and the first family tree of the region's ancient sabertooths. Their results suggest that the distribution of sabertooths throughout ancient Africa might have been different than previously assumed, and the study provides important information about Africa's paleoenvironment.
Published Aluminum materials show promising performance for safer, cheaper, more powerful batteries
(via sciencedaily.com) Researchers are using aluminum foil to create batteries with higher energy density and greater stability. The team's new battery system could enable electric vehicles to run longer on a single charge and would be cheaper to manufacture -- all while having a positive impact on the environment.
Published Current thinking on batteries overturned by cathode oxidation research
(via sciencedaily.com) Scientists have made a significant breakthrough in understanding and overcoming the challenges associated with Ni-rich cathode materials used in lithium-ion batteries.
Published Dry manufacturing process offers path to cleaner, more affordable high-energy EV batteries
(via sciencedaily.com) Early experiments have revealed significant benefits to a dry battery manufacturing process. This eliminates the use of toxic solvents while showing promise for delivering a battery that is durable, less weighed down by inactive elements and able to maintain high energy storage capacity after use. Such improvements could boost wider EV adoption, helping to reduce carbon emissions and achieve U.S. climate goals.
Published Unusual fossil shows rare evidence of a mammal attacking a dinosaur
(via sciencedaily.com) Original source Scientists have described an unusual fossil from around 125 million years ago in China that shows a dramatic moment in time when a carnivorous mammal attacked a larger plant-eating dinosaur. The two animals are locked in mortal combat, and it's among the first evidence to show actual predatory behavior by a mammal on a dinosaur. The fossil's presence challenges the view that dinosaurs had few threats from their mammal contemporaries during the Cretaceous, when dinosaurs were the dominant animals.
Published All about the Benjamins: Researchers decipher the secrets of Benjamin Franklin's paper money
(via sciencedaily.com) Original source During his career, Benjamin Franklin printed nearly 2,500,000 money notes for the American Colonies using what the researchers have identified as highly original techniques.
Published Ice Age saber-tooth cats and dire wolves suffered from diseased joints
(via sciencedaily.com) Original source Ice Age saber-tooth cats and dire wolves experienced a high incidence of bone disease in their joints, according to new research.
Published Next-generation flow battery design sets records
(via sciencedaily.com) A new flow battery design achieves long life and capacity for grid energy storage from renewable fuels.
Published New design rule for high-entropy superionic solid-state conductors
(via sciencedaily.com) Solid electrolytes with high lithium-ion conductivity can be designed for millimeter-thick battery electrodes by increasing the complexity of their composite superionic crystals, report researchers from Tokyo Tech. This new design rule enables the synthesis of high-entropy active materials while preserving their superionic conduction.
Published Why there are no kangaroos in Bali (and no tigers in Australia)
(via sciencedaily.com) Original source Researchers are using a new model to clarify why millions of years ago more animal species from Asia made the leap to the Australian continent than vice versa. The climate in which the species evolved played an important role.
Published Giant stone artefacts found on rare Ice Age site in Kent, UK
(via sciencedaily.com) Original source Researchers have discovered some of the largest early prehistoric stone tools in Britain.
Published Fossils reveal how ancient birds molted their feathers -- which could help explain why ancestors of modern birds survived when all the other dinosaurs died
(via sciencedaily.com) Original source Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers.
Published Apex predator of the Cambrian likely sought soft over crunchy prey
(via sciencedaily.com) Original source Biomechanical studies on the arachnid-like front 'legs' of an extinct apex predator show that the 2-foot (60-centimeter) marine animal Anomalocaris canadensis was likely much weaker than once assumed. One of the largest animals to live during the Cambrian, it was probably agile and fast, darting after soft prey in the open water rather than pursuing hard-shelled creatures on the ocean floor.
Published Nanosheet technology developed to boost energy storage dielectric capacitors
(via sciencedaily.com) A research group has used nanosheet technology to develop a dielectric capacitor for advanced electronic and electrical power systems. Innovations in energy storage technology are vital for the effective use of renewable energy and the mass production of electric vehicles. The capacitor has the highest energy storage density recorded. It has a short charging time, high output, long life, and high temperature stability, making it a major advancement in technology.
Published New aluminium radical battery promises more sustainable power
(via sciencedaily.com) Scientists are hoping to make the world's first safe and efficient non-toxic aqueous aluminum radical battery. Scientists have now reported the first stage of developing these novel batteries.
Published Neutrons look inside working solid-state battery to discover its key to success
(via sciencedaily.com) Original source Researchers have used neutron reflectometry to peer inside a working solid-state battery and monitor its electrochemistry. They discovered that its excellent performance results from an extremely thin layer, across which charged lithium atoms quickly flow as they move from anode to cathode and blend into a solid electrolyte.
Published How urea may have been the gateway to life
(via sciencedaily.com) Original source Urea reacts extremely quickly under the conditions that existed when our planet was newly formed. This new insight furthers our understanding of how life on Earth might have begun.
