(via sciencedaily.com) Graphene nanoribbons have outstanding properties that can be precisely controlled. Researchers have succeeded in attaching electrodes to individual atomically precise nanoribbons, paving the way for precise characterization of the fascinating ribbons and their possible use in quantum technology.
Published Researchers develop a unique quantum mechanical approach to determining metal ductility
(via sciencedaily.com) A team of scientists developed a new quantum-mechanics-based approach to predict metal ductility. The team demonstrated its effectiveness on refractory multi-principal-element alloys.
Published Elephant ancestors´ teeth evolved in response to long term changes in diet and climate in Africa
(via sciencedaily.com) Original source A new study shows that the cheek teeth of proboscideans (elephants and their ancient relatives) evolved in response to dietary changes due to vegetation changes and climate change in East Africa during the last 26 million years.
Published Behind the rind: New genomic insights into watermelon evolution, quality, and resilience
(via sciencedaily.com) Original source Scientists have constructed a comprehensive 'super-pangenome' for watermelon and its wild relatives, uncovering beneficial genes lost during domestication that could improve disease resistance and fruit quality of this vital fruit crop.
Published Arrays of quantum rods could enhance TVs or virtual reality devices
(via sciencedaily.com) Using scaffolds of folded DNA, engineers assembled arrays of quantum rods with desirable photonic properties that could enable them to be used as highly efficient micro-LEDs for televisions or virtual reality devices.
Published High-precision genome sequencing of buckwheat breeds hope for future harvests
(via sciencedaily.com) Original source Buckwheat's high-precision chromosomal-level genome sequence has been deciphered, a key step toward unraveling the evolution of the buckwheat genome and the origins of the cultivated crop. By altering specific genes using a method independent of common genome-editing techniques, the researchers successfully developed a self-fertile buckwheat variety as well as a new type of the crop with a sticky, mochi-like texture. This breeding method may contribute to a more diverse range of orphan crops than what is possible with existing genome editing technologies.
Published Hidden moles in hidden holes
(via sciencedaily.com) Original source An international team of scientists has for the first time identified two new underground mammals that could have been living, undetected, in eastern Turkey for up to 3 million years. They say it is rare to find new species of mammals today, and evidence that the true nature of biodiversity can be under-estimated.
Published Evolving elegance: Scientists connect beauty and safeguarding in ammonoid shells
(via sciencedaily.com) Original source With 350 million years of evolution culminating in almost two centuries of scientific discourse, a new hypothesis emerges. Researchers propose a new explanation for why ammonoids evolved a highly elaborate, fractal-like geometry within their shells. Their analysis shows that the increasing complexity of shell structures provided a distinct advantage by offering improved protection against predators.
Published Global consortium creates large-scale, cross-species database and universal 'clock' to estimate age in all mammalian tissues
(via sciencedaily.com) Original source An international research team details changes in DNA that researchers found are shared by humans and other mammals throughout history and are associated with life span and numerous other traits.
Published Biologists find what colors a butterfly's world
(via sciencedaily.com) Original source As butterflies flit among flowers, they don't all view blossoms the same way. In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. Biologists have discovered that in at least one species, the variation results from a vision gene's jump onto a sex chromosome. It's the first known finding that this kind of genetic change causes sexually dimorphic vision.
Published Potential application of unwanted electronic noise in semiconductors
(via sciencedaily.com) Random telegraph noise (RTN) in semiconductors is typically caused by two-state defects. Two-dimensional (2D) van der Waals (vdW) layered magnetic materials are expected to exhibit large fluctuations due to long-range Coulomb interaction; importantly, which could be controlled by a voltage compared to 3D counterparts having large charge screening. Researchers reported electrically tunable magnetic fluctuations and RTN signal in multilayered vanadium-doped tungsten diselenide (WSe2) by using vertical magnetic tunneling junction devices. They identified bistable magnetic states in the 1/f2 RTNs in noise spectroscopy, which can be further utilized for switching devices via voltage polarity.
Published The oldest and fastest evolving moss in the world might not survive climate change
(via sciencedaily.com) Original source A 390-million-year-old moss called Takakia lives in some of Earth's most remote places, including the icy cliffs of the Tibetan Plateau. In a decade-long project, a team of scientists climbed some of the tallest peaks in the world to find Takakia, sequence its DNA for the first time, and study how climate change is impacting the moss. Their results show that Takakia is one of the fastest evolving species ever studied -- but it likely isn't evolving fast enough to survive climate change.
Published Researchers use SPAD detector to achieve 3D quantum ghost imaging
(via sciencedaily.com) Researchers have reported the first 3D measurements acquired with quantum ghost imaging. The new technique enables 3D imaging on a single photon level, yielding the lowest photon dose possible for any measurement.
Published Quantum material exhibits 'non-local' behavior that mimics brain function
(via sciencedaily.com) New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.
Published Parasites of viruses drive superbug evolution
(via sciencedaily.com) Original source Researchers have discovered a previously unknown mechanism by which bacteria share their genetic material through virus parasites. The insights could help scientists to better understand how bacteria rapidly adapt and evolve, and how they become more virulent and resistant to antibiotics.
Published How the hospital pathogen Acinetobacter baumannii quickly adapts to new environmental conditions
(via sciencedaily.com) Original source Hospital-acquired infections are often hard to treat because the corresponding pathogens become increasingly resistant against antibiotics. The bacterium Acinetobacter baumannii is particularly feared, and there is great pressure to devise novel therapeutic approaches to combat it. Bioinformaticians have now detected an unexpectedly wide diversity of certain cell appendages in A. baumannii that are associated with pathogenicity. This could lead to treatment strategies that are specifically tailored to a particular pathogen.
