Published Scientists assess how large dinosaurs could really get
(via sciencedaily.com) Original source A study looks at the maximum possible sizes of dinosaurs, using the carnivore, Tyrannosaurus rex, as an example. Using computer modelling, experts produced estimates that T. Rex might have been 70% heavier than what the fossil evidence suggests.
Published Whale shark tracked for record-breaking four years
(via sciencedaily.com) Original source Researchers have been tracking a 26-foot endangered whale shark -- named 'Rio Lady' -- with a satellite transmitter for more than four years -- a record for whale sharks and one of the longest tracking endeavors for any species of shark.
Published Eyes for Love: Searching for light and a mate in the deep, dark sea, male dragonfishes grow larger eyes than the females they seek
(via sciencedaily.com) Original source The eyes of the male dragonfish grow larger for mate seeking, a sexual dimorphism that makes the dragonfish an anomaly in vertebrate evolution, researchers report.
Published A new way to make element 116 opens the door to heavier atoms
(via sciencedaily.com) Original source Researchers have successfully made super-heavy element 116 using a beam of titanium-50. That milestone sets the team up to attempt making the heaviest element yet: 120.
Published Taco-shaped arthropod fossils gives new insights into the history of the first mandibulates
(via sciencedaily.com) Original source Palaeontologists are helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period. Fossils reveal Odaraia had mandibles. Palaeontologists are finally able to place it as belonging to the mandibulates, ending its long enigmatic classification among the arthropods since it was first discovered in the Burgess Shale over 100 years ago and revealing more about early evolution and diversification.
Published Butterflies accumulate enough static electricity to attract pollen without contact
(via sciencedaily.com) Original source Butterflies and moths collect so much static electricity whilst in flight, that pollen grains from flowers can be pulled by static electricity across air gaps of several millimeters or centimeters.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation
(via sciencedaily.com) Original source Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
Published Fruit fly post-mating behavior controlled by male-derived peptide via command neurons, study finds
(via sciencedaily.com) Original source Scientists have succeeded in pinpointing the neurons within a female fruit fly's brain that respond to signals from the male during mating.
Published A promising new method uses light to clean up forever chemicals
(via sciencedaily.com) Original source A room-temperature method to decompose perfluoroalkyl substances (PFASs) using visible LED light offers a promising solution for sustainable fluorine recycling and PFAS treatment.
Published Team develops safe and long-cyclable lithium metal battery for high temperatures
(via sciencedaily.com) Original source In recent years, batteries have become ubiquitous in consumers' daily lives. However, existing commercial battery technologies, which use liquid electrolytes and carbonaceous anodes, have certain drawbacks such as safety concerns, limited lifespan, and inadequate power density particularly at high temperatures.
Published Researchers develop new method for achieving controllable tuning and assessing instability in 2D materials for engineering applications
(via sciencedaily.com) Original source Two-dimensional (2D) materials have atomic-level thickness and excellent mechanical and physical properties, with broad application prospects in fields such as semiconductors, flexible devices, and composite materials.
Published Smell of human stress affects dogs' emotions leading them to make more pessimistic choices
(via sciencedaily.com) Original source Dogs experience emotional contagion from the smell of human stress, leading them to make more 'pessimistic' choices, new research finds. Researchers tested how human stress odors affect dogs' learning and emotional state.
Published Controlling mosquito populations through genetic breeding
(via sciencedaily.com) Original source Researchers have found a new way to identify genetic targets useful for control of mosquito populations, potentially offering an alternative to insecticides. Their study focused on the genetic basis of species incompatibility. They crossed Ae. aegypti, a major global arboviral disease vector, and its sibling species, Ae. mascarensis, from the Indian Ocean. When offspring is crossed back with one parent, about 10 percent of the progeny becomes intersex and is unable to reproduce.
Published Birds need entertainment during avian flu lockdowns
(via sciencedaily.com) Original source Birds need varied activities during avian flu lockdowns, new research shows.
Published Organs on demand? Scientists print voxel building blocks
(via sciencedaily.com) Original source Scientists are bioprinting 3D structures with a material that is a close match for human tissue, paving the way for true biomanufacturing.
Published Chimpanzees gesture back and forth quickly like in human conversations
(via sciencedaily.com) Original source When people are having a conversation, they rapidly take turns speaking and sometimes even interrupt. Now, researchers who have collected the largest ever dataset of chimpanzee 'conversations' have found that they communicate back and forth using gestures following the same rapid-fire pattern.
Published Waste Styrofoam can now be converted into polymers for electronics
(via sciencedaily.com) Original source A new study describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known as PEDOT:PSS. Researchers also noted that the upgraded plastic waste can be successfully incorporated into functional electronic devices, including silicon-based hybrid solar cells and organic electrochemical transistors.
Published Chemists design novel method for generating sustainable fuel
(via sciencedaily.com) Original source Chemists have been working to synthesize high-value materials from waste molecules for years.
Published The courtship of leopard seals off the coast of South America
(via sciencedaily.com) Original source A pioneering study has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. The study on the mysterious leopard seal represents a major advance in understanding the behavior of one of the most difficult apex predators to study on Earth.
Published Soft, stretchy 'jelly batteries' inspired by electric eels
(via sciencedaily.com) Original source Researchers have developed soft, stretchable 'jelly batteries' that could be used for wearable devices or soft robotics, or even implanted in the brain to deliver drugs or treat conditions such as epilepsy.
