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 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 App-based tool quantifies pesticide toxicity in watersheds; identifies mitigation opportunities
(via sciencedaily.com) Original source Pesticides are a leading source of chemical hazards in aquatic environments. Researchers have introduced a new tool to help evaluate toxicity at high resolution and suggests that targeting a small number of pesticides in a few watersheds could significantly reduce aquatic toxicity in California's agricultural centers.
Published Top fish predators could suffer wide loss of suitable habitat by 2100 due to climate change
(via sciencedaily.com) Original source A study of 12 species of highly migratory fish predators -- including sharks, tuna, and billfish such as marlin and swordfish -- finds that most of them will encounter widespread losses of suitable habitat and redistribution from current habitats in the Northwest Atlantic Ocean (NWA) and the Gulf of Mexico (GOM) by 2100. These areas are among the fastest warming ocean regions and are projected to increase between 1-6°C (+1-10°F) by the end of the century, a sign of climate-driven changes in marine ecosystems.
Published Classroom environmental education doesn't change attitudes
(via sciencedaily.com) Original source Researchers evaluated the effectiveness of conservation educational activities in the Cape Verde Island of Maio.
Published Marine protected areas overwhelmingly manage with climate change in mind
(via sciencedaily.com) Original source Scientific findings don't always translate neatly into actions, especially in conservation and resource management. The disconnect can leave academics and practitioners disheartened and a bit frustrated.
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 City-dwelling wildlife demonstrate 'urban trait syndrome'
(via sciencedaily.com) City life favors species that are adaptable and not too fussy about what they eat, among other characteristics. A worldwide consortium of scientists calls the resulting collection of traits an 'Urban Trait Syndrome.'
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 Managing domestic and wildcats is likely to remain fraught, new research warns
(via sciencedaily.com) Original source Current efforts to protect and restore native biodiversity is being threatened by difficulties in identifying wild and domestic cats, and categorization is likely to remain fraught for the foreseeable future, experts have warned.
Published New Antarctic extremes 'virtually certain' as world warms
(via sciencedaily.com) Original source Extreme events in Antarctica such as ocean heatwaves and ice loss will almost certainly become more common and more severe, researchers say.
Published Bat activity lower at solar farm sites
(via sciencedaily.com) The activity level of six bat species was significantly reduced at solar farm sites, researchers have observed.
Published Study reveals successful strategies for removing invasive caimans from Florida Everglades
(via sciencedaily.com) A new study reveals how a succession of strategies can take control of an invasive species population.
Published Kordofan giraffes face local extinction if poaching continues
(via sciencedaily.com) Original source Poaching of two Critically Endangered Kordofan giraffes per year could result in extinction in just 15 years within Cameroon's Bénoué National Park without intervention.
Published Tropical trees use social distancing to maintain biodiversity
(via sciencedaily.com) Original source Tropical forests can harbor hundreds of species of trees in one square mile. Researchers reveal key factors in the spatial distribution of adult trees.
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.
Published Unleashing a new era of color tunable nano-devices -- smallest ever light source with switchable colors formed
(via sciencedaily.com) New research has achieved a significant breakthrough in color switching for nanocrystals, unlocking exciting possibilities for a simple, energy efficient display design and for tunable light sources needed in numerous technologies. The discovery also has potential applications in sensitive sensors for various substances, including biological and neuroscience uses, as well as advancements in quantum communication technologies.

Published Sensing and controlling microscopic spin density in materials
(via sciencedaily.com) Researchers found a way to tune the spin density in diamond by applying an external laser or microwave beam. The finding could open new possibilities for advanced quantum devices.
Published Nanorings: New building blocks for chemistry
(via sciencedaily.com) Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear. Recently, researchers made stacked sandwich complexes form a nano-sized ring. Physical and other properties of these cyclocene structures will now be further investigated.
Published Scientists dig into wildfire predictions, long-term impacts
(via sciencedaily.com) Original source Wildfires are an ancient force shaping the environment, but they have grown in frequency, range and intensity in response to a changing climate. Scientists are working on several fronts to better understand and predict these events and what they mean for the carbon cycle and biodiversity.
