Published A new vibrant blue pottery pigment with less cobalt
(via sciencedaily.com) Original source Whether ultramarine, cerulean, Egyptian or cobalt, blue pigments have colored artworks for centuries. Now, seemingly out of the blue, scientists have discovered a new blue pigment that uses less cobalt but still maintains a brilliant shine. Though something like this might only happen once in a blue moon, the cobalt-doped barium aluminosilicate colorant withstands the high temperatures found in a kiln and provides a bright color to glazed tiles.
Published Physicists discover a quantum state with a new type of emergent particles: Six-flux composite fermions
(via sciencedaily.com) Original source Physicists have reported a new fractional quantum Hall state that is very different from all other known fractional states and will invoke the existence of a new type of emergent particle, which they are calling six-flux composite fermions.
Published Butterfly and moth genomes mostly unchanged despite 250 million years of evolution
(via sciencedaily.com) Original source Comparison of over 200 high-quality butterfly and moth genomes reveals key insights into their biology, evolution and diversification over the last 250 million years, as well as clues for conservation.
Published Kiss-and-tell: A new method for precision delivery of nanoparticles and small molecules to individual cells
(via sciencedaily.com) Original source The delivery of experimental materials to individual cells with exactness and exclusivity has long been an elusive and much sought-after ability in biology. With it comes the promise of deciphering many longstanding secrets of the cell. A research team has now successfully shown how small molecules and single nanoparticles can be applied directly onto the surface of cells. In the study the scientists describe their technique as a ' kiss' (microkiss) -- an easy and cost-effective new method, unlocking new possibilities in single-cell science with a view towards next generation therapeutic applications.
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 Electrons become fractions of themselves in graphene
(via sciencedaily.com) Original source Physicists have observed fractional quantum Hall effect in simple pentalayer graphene. The finding could make it easier to develop more robust quantum computers.
Published Scientists invent ultra-thin, minimally-invasive pacemaker controlled by light
(via sciencedaily.com) Original source A team of researchers has developed a wireless device, powered by light, that can be implanted to regulate cardiovascular or neural activity in the body. The feather-light membranes, thinner than a human hair, can be inserted with minimally invasive surgery and contain no moving parts.
Published 'The future is fungal': New research finds that fungi that live in healthy plants are sensitive to climate change
(via sciencedaily.com) Original source Findings more than a decade in the making reveal a rich diversity of beneficial fungi living in boreal forest trees, with implications for the health of forests.
Published Engineering a coating for disease-free produce
(via sciencedaily.com) Original source Texas A&M researchers combine food-grade wax with essential oils to defend produce from bacteria.
Published Giant new snake species identified in the Amazon
(via sciencedaily.com) Original source A team of scientists on location with a film crew in the remote Amazon has uncovered a previously undocumented species of giant anaconda.
Published Engineers achieve breakthrough in quantum sensing
(via sciencedaily.com) Original source A collaborative project has made a breakthrough in enhancing the speed and resolution of wide-field quantum sensing, leading to new opportunities in scientific research and practical applications.
Published Using metabolomics for assessing safety of chemicals may reduce the use of lab rats
(via sciencedaily.com) Original source Scientists have discovered a more robust way of grouping chemicals and using read-across for toxicological data to meet regulatory requirements, which could greatly reduce animal testing.
Published It's the spin that makes the difference
(via sciencedaily.com) Original source Biomolecules such as amino acids and sugars occur in two mirror-image forms -- in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.
Published Road to better performing batteries using less critical raw materials
(via sciencedaily.com) Original source Researchers are developing batteries that can charge faster, offer more stable storage and are made of sustainable materials that are widely available. In doing so, they offer a cheaper alternative to lithium-ion batteries that consist of rare materials and have a high CO2 -footprint.
Published Physicists develop more efficient solar cell
(via sciencedaily.com) Original source Physicists have used complex computer simulations to develop a new design for significantly more efficient solar cells than previously available. A thin layer of organic material, known as tetracene, is responsible for the increase in efficiency.
Published Accelerating the discovery of single-molecule magnets with deep learning
(via sciencedaily.com) Original source Single-molecule magnets (SMMs) are exciting materials. In a recent breakthrough, researchers have used deep learning to predict SMMs from 20,000 metal complexes. The predictions were made solely based on the crystal structures of these metal complexes, thus eliminating the need for time-consuming experiments and complex simulations. As a result, this method is expected to accelerate the development of functional materials, especially for high-density memory and quantum computing devices.
Published Plastic recycling with a protein anchor
(via sciencedaily.com) Original source Polystyrene is a widespread plastic that is essentially not recyclable when mixed with other materials and is not biodegradable. A research team has now introduced a biohybrid catalyst that oxidizes polystyrene microparticles to facilitate their subsequent degradation. The catalyst consists of a specially constructed 'anchor peptide' that adheres to polystyrene surfaces and a cobalt complex that oxidizes polystyrene.
Published Nature's checkup: Surveying biodiversity with environmental DNA sequencing
(via sciencedaily.com) Original source A thousand kilometers south of Tokyo, far into the largest ocean on Earth, lies a chain of small, volcanic islands -- the Ogasawara Islands. Nature has been able to develop on its own terms here, far from both humans and the warm Kuroshio current, which acts like a shuttle, moving marine species from Taiwan, over the Ryukyu Islands, and up the Pacific coast of mainland Japan. With upwards of 70 % of trees and many animal species being endemic to the archipelago, the islands have been dubbed 'the Galapagos of the East', as they are valuable as both a biodiversity hotspot and a cradle of scientific discovery.
Published Spy-satellite images offer insights into historical ecosystem changes
(via sciencedaily.com) Original source New study advocates the use of more than one million declassified images for ecology and conservation. The images can offer better insights into the historical changes of ecosystems, species populations or changes in human influences on the environment dating back to the 1960s. Collaboration between ecologists, conservationists, and remote sensing experts is necessary to explore the full potential of the data.
Published Improving traffic signal timing with a handful of connected vehicles
(via sciencedaily.com) Original source With GPS data from as little as 6% of vehicles on the road, researchers can recalibrate traffic signals to significantly reduce congestion and delays at intersections.
