Published Edge-to-edge assembly technique for 2D nanosheets
(via sciencedaily.com) Original source A research team develops edge-to-edge assembly technique for 2D nanosheets.
Published Scammed! Animals 'led by the nose' to leave plants alone
(via sciencedaily.com) Original source Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.
Published How leafcutter ants cultivate a fungal garden to degrade plants and provide insights into future biofuels
(via sciencedaily.com) Original source Scientists developed a new method to map exactly how a fungus works with leafcutter ants in a complex microbial community to degrade plant material at the molecular level. The team's insights are important for biofuels development.
Published Zebrafish navigate to find their comfortable temperature
(via sciencedaily.com) Original source Zebrafish are smaller than your little finger, with a brain no more than half the size of a pinhead. Yet these animals possess an efficient navigation system that enables them to find their way back to spots in the water where the temperature suits them.
Published Clown anemonefish seem to be counting bars and laying down the law
(via sciencedaily.com) Original source We often think of fish as carefree swimmers in the ocean, reacting to the world around them without much forethought. However, new research suggests that our marine cousins may be more cognizant than we credit them for. Fish may be counting vertical bars on intruders to determine their threat level, and to inform the social hierarchy governing their sea anemone colonies.
Published Relocated songbirds can successfully learn the diversity of song they need to survive
(via sciencedaily.com) Original source New research focused on a population of cirl bunting reintroduced into Cornwall from 2006 as part of a major conservation program. It suggests that if the translocation of nestlings is deemed necessary for conservation purposes, it may not lead to long-term problems for communication and population persistence.
Published Single proton illuminates perovskite nanocrystals-based transmissive thin scintillators
(via sciencedaily.com) Original source Researchers have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons. The exceptional sensitivity is attributed to biexcitonic radiative emission generated through proton-induced upconversion and impact ionization.
Published Key dynamics of 2D nanomaterials: View to larger-scale production
(via sciencedaily.com) Original source A team of researchers mapped out how flecks of 2D materials move in liquid -- knowledge that could help scientists assemble macroscopic-scale materials with the same useful properties as their 2D counterparts.
Published Intensifying the production of high-value compounds from industrial waste
(via sciencedaily.com) Original source New research demonstrates how glycerol carbonate, a biosourced industrial additive, can be produced in record time using CO2 and a by-product of the cooking oil recycling industry. The process relies on a hybrid approach combining fundamental physical organic chemistry and applied flow process technology. Two industrial wastes are thus converted into glycerol carbonate, a biosourced rising star with high added-value.
Published Engineers unmask nanoplastics in oceans for the first time, revealing their true shapes and chemistry
(via sciencedaily.com) Original source Millions of tons of plastic waste enter the oceans each year. The sun's ultraviolet light and ocean turbulence break down these plastics into invisible nanoparticles that threaten marine ecosystems. In a new study, engineers have presented clear images of nanoplastics in ocean water off the coasts of China, South Korea and the United States, and in the Gulf of Mexico. These tiny plastic particles, which originated from such consumer products as water bottles, food packaging and clothing, were found to have surprising diversity in shape and chemical composition.
Published Climate change threatens older elephants most, jeopardizing African elephants' future
(via sciencedaily.com) Original source A collaborative team of researchers has conducted first-of-its kind research into how global climate change affects African elephants. The work shows that older elephants will have markedly decreased chances of survival, which will not only drastically reduce the species' overall ability to weather the changing climate but will send ripple effects throughout the surrounding landscape. The team has also modeled possible mitigation scenarios.
Published Floating algae a raft for juvenile pelagic fish
(via sciencedaily.com) Original source Floating macroalgal acts as a raft that provides habitat for a diverse array of juvenile oceanic fish a new study has found. The study conducted in the Ningaloo Coast World Heritage Area, Western Australia, revealed that fish were more abundant around macroalgal rafts than in open water, with eleven species of juvenile fishes associated with Sargassum rafts, and one species of both juveniles and adults.
Published Machine learning guides carbon nanotechnology
(via sciencedaily.com) Original source Carbon nanostructures could become easier to design and synthesize thanks to a machine learning method that predicts how they grow on metal surfaces. The new approach will make it easier to exploit the unique chemical versatility of carbon nanotechnology.
Published Ambitious roadmap for circular carbon plastics economy
(via sciencedaily.com) Original source Researchers have outlined ambitious targets to help deliver a sustainable and net zero plastic economy. The authors argue for a rethinking of the technical, economic, and policy paradigms that have entrenched the status-quo, one of rising carbon emissions and uncontrolled pollution.
Published Decarbonizing the world's industries
(via sciencedaily.com) Original source Harmful emissions from the industrial sector could be reduced by up to 85% across the world, according to new research. The sector, which includes iron and steel, chemicals, cement, and food and drink, emits around a quarter of global greenhouse gas (GHG) emissions -- planet-warming gases that result in climate change and extreme weather.
Published Scientists pinpoint growth of brain's cerebellum as key to evolution of bird flight
(via sciencedaily.com) Original source Evolutionary biologists report they have combined PET scans of modern pigeons along with studies of dinosaur fossils to help answer an enduring question in biology: How did the brains of birds evolve to enable them to fly?
Published A green alternative for treating Streptococcus iniae bacteria in hybrid striped bass
(via sciencedaily.com) Original source Scientists have developed a green antibiotic alternative to treat the deadly pathogen Streptococcus iniae in hybrid striped bass, the fourth most farmed finfish in the United States, according to a recent study.
Published Goats can tell if you are happy or angry by your voice alone
(via sciencedaily.com) Original source Goats can tell the difference between a happy-sounding human voice and an angry-sounding one, according to researchers. A new study reveals that goats may have developed a sensitivity to our vocal cues over their long association with humans.
Published Small yet mighty: Showcasing precision nanocluster formation with molecular traps
(via sciencedaily.com) Original source Nanoclusters (NCs) of transition metals like cobalt or nickel have widespread applications in drug delivery and water purification, with smaller NCs exhibiting improved functionalities.
