Published Nuclear expansion failure shows simulations require change
(via sciencedaily.com) Original source A team of researchers looked back at a model that predicted nuclear power would expand dramatically in order to assess the efficacy of energy policies implemented today.
Published Hemp cannabinoids may have evolved to deter insect pests
(via sciencedaily.com) Original source Cannabinoids, naturally occurring compounds found in hemp plants, may have evolved to deter pests from chewing on them, according to new research that showed higher cannabinoid concentrations in hemp leaves led to proportionately less damage from insect larvae.
Published Water splitting reaction for green hydrogen gas production improved
(via sciencedaily.com) Original source Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have now designed an electrode with Schottky Junction formed at the interface of metallic Ni-W5N4 and semiconducting NiFeOOH. The proposed electrode shows excellent catalytic activity and can facilitate industrial seawater splitting continuously for 10 days.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers
(via sciencedaily.com) Original source Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
Published Using cosmetic ingredient for battery protection
(via sciencedaily.com) Original source A research team has devised a battery electrode protective film using biopolymers sourced from cosmetic ingredients.
Published New water treatment method can generate green energy
(via sciencedaily.com) Original source Researchers have designed micromotors that move around on their own to purify wastewater. The process creates ammonia, which can serve as a green energy source. Now, an AI method will be used to tune the motors to achieve the best possible results.
Published Putting sound waves to work to create safer public spaces
(via sciencedaily.com) Original source Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors built a system of piezoelectric sensors that can be installed in walls, floors, and ceilings to absorb sound waves and collect their energy. They used computer simulations to fine-tune variables including the voltage needed to power the main device component, the frequency and intensity of the input sound, and piezoelectric sensors tested in parallel and serial configurations.
Published New study reveals surprising insights into feeding habits of carnivorous dinosaurs in North America
(via sciencedaily.com) Original source New research sheds light on the dining habits of ancient carnivorous dinosaurs from Jurassic rocks of the USA. A recent study explores the bite marks left on the ancient bones of the giant long-necked sauropod dinosaurs like Diplodocus and Brontosaurus by carnivorous theropod dinosaurs.
Published 'Cooling glass' blasts building heat into space
(via sciencedaily.com) Original source Researchers aiming to combat rising global temperatures have developed a new 'cooling glass' that can turn down the heat indoors without electricity by drawing on the cold depths of space. The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10 percent.
Published Ammonia for fertilizers without the giant carbon footprint
(via sciencedaily.com) Original source Green ammonia has the potential to drastically reduce the carbon footprint needed to produce fertilizer vital for crop-growing.
Published Evolution of taste: Early sharks were able to perceive bitter substances
(via sciencedaily.com) Original source New genetic data show that humans and sharks share bitter taste receptors, even though their evolutionary pathways separated nearly 500 million years ago.
Published Mysterious new moth species discovered in Europe
(via sciencedaily.com) Original source European Lepidoptera (butterflies and moths), with a currently known inventory of approximately 11,000 species, are generally considered well-researched. However, a new genus and species from the Geometrid moth family tell a different story. The moth, named Mirlatia arcuata, is one of the most remarkable discoveries in Lepidoptera of recent decades.
Published Yucatán's underwater caves host diverse microbial communities
(via sciencedaily.com) Original source With help from an experienced underwater cave-diving team, researchers have constructed the most complete map to date of the microbial communities living in the submerged labyrinths beneath Mexico's Yucatán Peninsula. Researchers found the cave system's microbiome is distinct from the nearby sea, and microbial communities vary between cave systems forming distinct 'neighborhoods.'
Published Hummingbirds' unique sideways flutter gets them through small apertures
(via sciencedaily.com) Original source Hummingbirds are highly maneuverable fliers, flitting forward and backward as they home in on flowers. But in the dense foliage many inhabit, they often encounter gaps that are too narrow for their wingspan. Since they can't bend their wings in flight, how do they get through? Researchers used high-speed cameras to capture their movements, discovering two unique strategies: they sidle through while fluttering, or fold their wings in a tuck and glide.
Published Found at last: Bizarre, egg-laying mammal finally rediscovered after 60 years
(via sciencedaily.com) Original source A long-beaked echidna named after Sir David Attenborough and last seen by scientists in 1961 has been photographed for the first time in an Indonesian tropical forest. An international team of researchers worked with local communities to deploy over 80 camera traps to film the elusive animal. Besides rediscovering the echidna, the team uncovered a wealth of species completely new to science, including beetles, spiders, and a remarkable tree-dwelling shrimp.
Published 'Indoor solar' to power the Internet of Things
(via sciencedaily.com) Original source From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled electrical cords or batteries that need to be replaced. Now, researchers have brought solar panel technology indoors to power smart devices. They show which photovoltaic (PV) systems work best under cool white LEDs, a common type of indoor lighting.
Published Advances in lithium-metal batteries, paving the way for safer, more powerful devices
(via sciencedaily.com) Original source The boom in phones, laptops and other personal devices over the last few decades has been made possible by the lithium-ion (Li-ion) battery, but as climate change demands more powerful batteries for electric vehicles and grid-scale renewable storage, lithium-ion technology might not be enough. Lithium-metal batteries (LMBs) have theoretical capacities an order of magnitude greater than lithium-ion, but a more literal boom has stymied research for decades.
Published Barnacle bends shape to fend off warm-water sea snails on the move
(via sciencedaily.com) Original source Some barnacles are 'morphing' to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change.
Published Palaeo-CSI: Mosasaurs were picky eaters
(via sciencedaily.com) Original source Mosasaurs, those large marine reptiles from the long-gone Cretaceous world, were quite picky in their choice of diet. Researchers came to this conclusion after studying the wear marks on mosasaur teeth.
Published First live birth of a chimeric monkey using embryonic stem cell lines
(via sciencedaily.com) Original source A team of researchers has reported for the first time the live birth of a monkey that contains a high proportion of cells derived from a monkey stem cell line. This 'chimeric' monkey is composed of cells that originate from two genetically distinct embryos of the same species of monkey. This has previously been demonstrated in rats and mice but, until now, has not been possible in other species, including non-human primates.
