Published With new experimental method, researchers probe spin structure in 2D materials for first time
(via sciencedaily.com) Original source In the study, a team of researchers describe what they believe to be the first measurement showing direct interaction between electrons spinning in a 2D material and photons coming from microwave radiation.
Published Researcher uses artificial intelligence to discover new materials for advanced computing
(via sciencedaily.com) Original source Researchers have identified novel van der Waals (vdW) magnets using cutting-edge tools in artificial intelligence (AI). In particular, the team identified transition metal halide vdW materials with large magnetic moments that are predicted to be chemically stable using semi-supervised learning. These two-dimensional (2D) vdW magnets have potential applications in data storage, spintronics, and even quantum computing.
Published Physicists discover 'stacked pancakes of liquid magnetism'
(via sciencedaily.com) Original source Physicists have discovered stacked pancakes of 'liquid' magnetism that may account for the strange electronic behavior of some layered helical magnets.
Published Quantum electrodynamics verified with exotic atoms
(via sciencedaily.com) Original source Adapting a detector developed for space X-ray observation, researchers have successfully verify strong-field quantum electrodynamics with exotic atoms.
Published A journey to the origins of multicellular life: Long-term experimental evolution in the lab
(via sciencedaily.com) Original source Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how snowflake yeast evolved to be physically stronger and more than 20,000 times larger than their ancestor. Their study is the first major report on the ongoing Multicellularity Long-Term Evolution Experiment (MuLTEE), which the team hopes to run for decades.
Published Crops evolved by swapping genetic modules between cells
(via sciencedaily.com) Original source Comparing individual cells across corn, sorghum, and millet reveals evolutionary differences among these important cereal crops, according to a new study. The findings bring researchers closer to pinpointing which genes control important agricultural traits such as drought tolerance, which will help scientists faced with a changing climate adapt crops to drier environments.
Published African rhinos share retroviruses not found in Asian rhinos or other related species
(via sciencedaily.com) Original source Rhinoceros belong to a mammalian order called odd-toed ungulates that also include horses and tapirs. They are found in Africa and Asia. Until recently, evidence suggested that throughout their evolutionary history, gamma-retroviruses such as Murine leukemia virus had not colonized their genomes, unlike most other mammalian orders. The colonization process is called retroviral endogenization and has resulted in most mammalian genomes being comprised of up to ten percent retroviral like sequences.
Published Basic 'toolkit' for organ development is illuminated by sea star
(via sciencedaily.com) Original source One of the basic and crucial embryonic processes to unfold in virtually every living organism is the formation of hollow, tubular structures that go on to form blood vessels or a digestive tract, and through branching and differentiation, complex organs including the heart and kidneys. This study illuminates fundamental design principles of tubulogenesis for all chordates, including mammals.
Published The bat's ability to convert energy into muscle power is affected by flight speed
(via sciencedaily.com) Original source Small bats are bad at converting energy into muscle power. Surprisingly, a new study led by Lund University in Sweden reveals that this ability increases the faster they fly.
Published Scientists create CRISPR-based drug candidate targeting the microbiome
(via sciencedaily.com) Original source A new drug candidate targeting E. coli in the gut is in phase 1 clinical trials. According to a new paper it may improve the well-being of blood cancer patients and reduce their mortality rate from E. coli infections.
Published 'Super-resolution' imaging technology
(via sciencedaily.com) Original source Researchers describe developing a super-resolution imaging platform technology to improve understanding of how nanoparticles interact within cells.
Published Scientists develop gene silencing DNA enzyme that can target a single molecule
(via sciencedaily.com) Original source Researchers have developed a DNA enzyme -- or DNAzyme -- that can distinguish between two RNA strands inside a cell and cut the disease-associated strand while leaving the healthy strand intact. This breakthrough 'gene silencing' technology could revolutionize the development of DNAzymes for treating cancer, infectious diseases and neurological disorders.
Published T cells can activate themselves to fight tumors
(via sciencedaily.com) Original source Scientists find an auto-signaling mechanism driving the T cell anti-tumor response; findings may inspire new cancer therapeutics and biomarkers.
Published New probe aids novel findings on cell functions
(via sciencedaily.com) Original source New research shows the use of a new cellular probe helped discover new findings about certain cellular processes.
Published An unprecedented view of gene regulation
(via sciencedaily.com) Original source Using a new technique, researchers have shown that they can map interactions between gene promoters and enhancers with 100 times higher resolution than has previously been possible.
Published Leaky-wave metasurfaces: A perfect interface between free-space and integrated optical systems
(via sciencedaily.com) Original source Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in free space. These are the first to demonstrate simultaneous control of all four optical degrees of freedom. Because they're so thin, transparent, and compatible with photonic integrated circuits, they can be used to improve optical displays, LIDAR, optical communications, and quantum optics.
Published Tiny microbes could brew big benefits for green biomanufacturing
(via sciencedaily.com) Original source Scientists find new route in bacteria to decarbonize industry. The discovery could reduce greenhouse gas emissions from the manufacturing of fuels, drugs, and chemicals. A research team has engineered bacteria to produce new-to-nature carbon products that could provide a powerful route to sustainable biochemicals.
Published Symmetric graphene quantum dots for future qubits
(via sciencedaily.com) Original source Quantum dots in semiconductors such as silicon or gallium arsenide have long been considered hot candidates for hosting quantum bits in future quantum processors. Scientists have now shown that bilayer graphene has even more to offer here than other materials. The double quantum dots they have created are characterized by a nearly perfect electron-hole-symmetry that allows a robust read-out mechanism -- one of the necessary criteria for quantum computing.
Published Elucidating the mysteries of enzyme evolution at the macromolecular level
(via sciencedaily.com) Original source Researchers have made a major breakthrough earlier this year in the field of evolutionary conservation of molecular dynamics in enzymes. Their work points to potential applications in health, including the development of new drugs to treat serious diseases such as cancer or to counter antibiotic resistance.
Published Researchers close to unleashing rapeseed's protein power for human consumption
(via sciencedaily.com) Original source Half of plant proteins in the EU come from rapeseed plants. Until now, the plant has only been used for oil and animal feed, as it is both bitter and unsafe for human consumption. In a new study, researchers have gotten closer to removing the plant's bitter substances, and in doing so, are paving the way for a new protein source to support the green transition.
