Published Scientists make nanoparticles dance to unravel quantum limits
(via sciencedaily.com) Original source The question of where the boundary between classical and quantum physics lies is one of the longest-standing pursuits of modern scientific research and in new research, scientists demonstrate a novel platform that could help us find an answer.
Published Umbrella for atoms: The first protective layer for 2D quantum materials
(via sciencedaily.com) Original source As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach.
Published Scientists ID burned bodies using technique used for extracting DNA from woolly mammoths, Neanderthals
(via sciencedaily.com) Original source A technique originally devised to extract DNA from woolly mammoths and other ancient archaeological specimens can be used to potentially identify badly burned human remains, according to research.
Published AI technique 'decodes' microscope images, overcoming fundamental limit
(via sciencedaily.com) Original source Researchers have developed a deep learning algorithm for removing systematic effects from atomic force microscopy images, enabling more precise profiles of material surfaces.
Published Climate change threatens thousands of archaeological sites in coastal Georgia
(via sciencedaily.com) Original source Thousands of historic and archaeological sites in Georgia are at risk from tropical storm surges, and that number will increase with climate change, according to a new study.
Published Experiment captures why pottery forms are culturally distinct
(via sciencedaily.com) Original source Potters of different cultural backgrounds learn new types differently, producing cultural differences even in the absence of differential cultural evolution. The research has implications for how we evaluate the difference of archaeological artifacts across cultures.
Published Want fewer microplastics in your tap water? Try boiling it first
(via sciencedaily.com) Original source Nano- and microplastics are seemingly everywhere -- water, soil and the air. While many creative strategies have been attempted to get rid of these plastic bits, one unexpectedly effective solution for cleaning up drinking water, specifically, might be as simple as brewing a cup of tea or coffee. Boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present.
Published Nanocarrier with escape reflex
(via sciencedaily.com) Original source Protein-based drugs must be transported into cells in a way that prevents their immediate degradation. A new approach is intended to ensure that they remain intact only in certain cells, such as cancer cells. A Japanese research team has introduced a nanocarrier that can 'escape' from endosomes before its cargo is destroyed there. This ability to escape is only triggered within the endosomes of certain tumor cells.
Published New disease testing component facilitates lower-cost diagnostics
(via sciencedaily.com) Original source Biomedical researchers have developed a new, less expensive way to detect nuclease digestion -- one of the critical steps in many nucleic acid sensing applications, such as those used to identify COVID-19 and other infectious diseases.
Published You may be breathing in more tiny nanoparticles from your gas stove than from car exhaust
(via sciencedaily.com) Original source Cooking on your gas stove can emit more nano-sized particles into the air than vehicles that run on gas or diesel, possibly increasing your risk of developing asthma or other respiratory illnesses, a new study has found.
Published Plant seed and fruit analysis from the biblical home of Goliath sheds unprecedented light on Philistine ritual practices
(via sciencedaily.com) Original source While many aspects of Philistine culture are well-documented, the specifics of Philistine religious practices and deities have long remained shrouded in mystery. A recent study contributes valuable new data to our understanding of the Philistine's ritual practices. The discovery of numerous plants in two temples unearthed at the site unraveled unprecedented insights into Philistine cultic rituals and beliefs -- their temple food ingredients, timing of ceremonies, and plants for temple decoration.
Published Researchers harness 2D magnetic materials for energy-efficient computing
(via sciencedaily.com) Original source Researchers used ultrathin van der Waals materials to create an electron magnet that can be switched at room temperature. This type of magnet could be used to build magnetic processors or memories that would consume far less energy than traditional devices made from silicon.
Published Graphene research: Numerous products, no acute dangers found by study
(via sciencedaily.com) Original source Graphene is an enormously promising material. It consists of a single layer of carbon atoms arranged in a honeycomb pattern and has extraordinary properties: exceptional mechanical strength, flexibility, transparency and outstanding thermal and electrical conductivity. If the already two-dimensional material is spatially restricted even more, for example into a narrow ribbon, controllable quantum effects can be created. This could enable a wide range of applications, from vehicle construction and energy storage to quantum computing.
Published Biggest Holocene volcano eruption found by seabed survey
(via sciencedaily.com) Original source A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.
Published New water batteries stay cool under pressure
(via sciencedaily.com) Original source A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.
Published An environmentally friendly way to turn seafood waste into value-added products
(via sciencedaily.com) Original source Reduce, reuse, recycle, and repurpose: These are all ways we can live more sustainably. One tricky aspect of recycling, though, is that sometimes the recycling process is chemically intensive, and this is the case for recycling one of the world's most abundant materials -- chitin. Researchers have tackled this problem and found a way to sustainably recover chitin from seafood waste.
Published Revolutionary breakthrough in solar energy: Most efficient QD solar cells
(via sciencedaily.com) Original source A research team has unveiled a novel ligand exchange technique that enables the synthesis of organic cation-based perovskite quantum dots (PQDs), ensuring exceptional stability while suppressing internal defects in the photoactive layer of solar cells.
Published Did neanderthals use glue? Researchers find evidence that sticks
(via sciencedaily.com) Original source Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher level of cognition and cultural development than previously thought.
Published Angle-dependent holograms made possible by metasurfaces
