(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 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 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 Researchers engineer bacteria that can detect tumor DNA
(via sciencedaily.com) Original source Creating new technologically advanced sensors, scientists have engineered bacteria that detect the presence of tumor DNA in live organisms. Their innovation could pave the way to new biosensors capable of identifying various infections, cancers and other diseases.
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 Scientists reverse hearing loss in mice
(via sciencedaily.com) Original source New research has successfully reversed hearing loss in mice. Scientists used a genetic approach to fix deafness in mice, restoring their hearing abilities in low and middle frequency ranges.
Published Surprising discovery of low-noise genes
(via sciencedaily.com) Original source While engaging in cell division research, researchers made a surprisingly quiet discovery. When cells express RNA, there is always some fluctuation, or noise, in how much RNA is produced. The scientists found several genes whose noise dips below a previously established threshold, known as the noise floor, during expression.
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 The 'unknome': A database of human genes we know almost nothing about
(via sciencedaily.com) Original source Researchers hope that a new, publicly available database they have created will shrink, not grow, over time. That's because it is a compendium of the thousands of understudied proteins encoded by genes in the human genome, whose existence is known but whose functions are mostly not.
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 Mineralization of bone matrix regulates tumor cell growth
(via sciencedaily.com) Original source Tumor cells are known to be fickle sleeper agents, often lying dormant in distant tissues for years before reactivating and forming metastasis. Numerous factors have been studied to understand why the activation occurs, from cells and molecules to other components in the so-called tissue microenvironment.
Published Astonishing complexity of bacterial circadian clocks
(via sciencedaily.com) Original source Bacteria make up more than 10% of all living things but until recently we had little realization that, as in humans, soil bacteria have internal clocks that synchronize their activities with the 24-hour cycles of day and night on Earth. New research shows just how complex and sophisticated these bacterial circadian clocks are, clearing the way for an exciting new phase of study.
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 Study finds a surprising new role for a major immune regulator
(via sciencedaily.com) Original source The immune regulatory protein STING has a previously unknown function: acting as an ion channel that allows protons to leak into cells. This discovery makes it the first human immune sensor that can translate danger signals into ion flow.
Published DNA tilts and stretches underlie differences in mutation rates across genomes
(via sciencedaily.com) Original source Researchers have changed the way to look at DNA. They show that DNA is much more than a linear sequence of building blocks; it has a 3D structure that influences the variation of human genome-wide mutation rates meaningfully and consistently, and this is likely conserved among species.
Published Current takes a surprising path in quantum material
(via sciencedaily.com) Researchers used magnetic imaging to obtain the first direct visualization of how electrons flow in a special type of insulator, and by doing so they discovered that the transport current moves through the interior of the material, rather than at the edges, as scientists had long assumed.
