Published Next epidemic could be spotted early in wastewater
(via sciencedaily.com) Original source Researchers behind the UK's first pilot public health surveillance system based on analysis of wastewater say that routine monitoring at sewage treatment works could provide a powerful early warning system for the next flu or norovirus epidemic, alerting hospitals to prepare and providing public health agencies with vital health information.
Published Observing group-living animals with drones and computer vision
(via sciencedaily.com) New method to study the movement, behaviour, and environmental context of group-living animals using drones and computer vision.
Published New mosquito species reported in Florida
(via sciencedaily.com) A mosquito known only by its scientific name, Culex lactator, is the latest to establish in the Sunshine State, according to a new study.
Published New simulation reveals secrets of exotic form of electrons called polarons
(via sciencedaily.com) Conditions mapped for the first time of polaron characteristics in 2D materials. TACC's Frontera supercomputer generated quantum mechanical calculations on hexagonal boron nitride system of 30,000 atoms.
Published Turn off porch light to aid caterpillars -- and safeguard backyard ecosystems
(via sciencedaily.com) Moderate levels of artificial light at night -- like the fixture illuminating your backyard -- bring more caterpillar predators and reduce the chance that these lepidoptera larvae grow up to become moths and serve as food for larger prey.
Published Researchers get to the 'bottom' of how beetles use their butts to stay hydrated
(via sciencedaily.com) Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.
Published To ward off aging, stem cells must take out the trash
(via sciencedaily.com) Researchers find stem cells use a surprising system for discarding misfolded proteins. This unique pathway could be the key to maintaining long-term health and preventing age-related blood and immune disorders.
Published How the 'marsupial sabertooth' thylacosmilus saw its world
(via sciencedaily.com) A new study investigates how an extinct, carnivorous marsupial relative with canines so large they extended across the top of its skull could hunt effectively despite having wide-set eyes, like a cow or a horse. The skulls of carnivores typically have forward-facing eye sockets, or orbits, which helps enable stereoscopic (3D) vision, a useful adaptation for judging the position of prey before pouncing. Scientists studied whether the 'marsupial sabertooth' Thylacosmilus atrox could see in 3D at all.
Published Forest growing season in eastern U.S. has increased by a month
(via sciencedaily.com) The growing period of hardwood forests in eastern North America has increased by an average of one month over the past century as temperatures have steadily risen, a new study has found.
Published Mind-control robots a reality?
(via sciencedaily.com) Researchers have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought control.
Published Another crystalline layer on crystal surface as a precursor of crystal-to-crystal transition
(via sciencedaily.com) Ice surfaces have a thin layer of water below its melting temperature of 0 degrees Celsius. Such premelting phenomenon is important for skating and snowflake growth. Similarly, liquid often crystallizes into a thin layer of crystal on a flat substrate before reaching its freezing temperature, i.e. prefreezing. The thickness of the surface layer usually increases and diverges as approaching the phase transition (such as melting and freezing) temperature. Besides premelting and prefreezing, whether similar surface phenomenon exists as a precursor of a phase transition has rarely been explored. Scientists now propose that a polymorphic crystalline layer may form on a crystal surface before the crystal-crystal phase transition and names it pre-solid-solid transition.
Published Nano cut-and-sew: New method for chemically tailoring layered nanomaterials could open pathways to designing 2D materials on demand
(via sciencedaily.com) A new process that lets scientists chemically cut apart and stitch together nanoscopic layers of two-dimensional materials -- like a tailor altering a suit -- could be just the tool for designing the technology of a sustainable energy future. Researchers have developed a method for structurally splitting, editing and reconstituting layered materials, called MAX phases and MXenes, with the potential of producing new materials with very unusual compositions and exceptional properties.
Published 3D internal structure of rechargeable batteries revealed
(via sciencedaily.com) Researchers have pioneered a technique to observe the 3D internal structure of rechargeable batteries. This opens up a wide range of areas for the new technique from energy storage and chemical engineering to biomedical applications.
Published Microscopy: Highest resolution in three dimensions
(via sciencedaily.com) Researchers have developed a super-resolution microscopy method for the rapid differentiation of molecular structures in 3D.
Published Graphene quantum dots show promise as novel magnetic field sensors
(via sciencedaily.com) Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with unique capabilities, according to a new study.
Published New material may offer key to solving quantum computing issue
(via sciencedaily.com) A new form of heterostructure of layered two-dimensional (2D) materials may enable quantum computing to overcome key barriers to its widespread application, according to an international team of researchers.
Published The quantum twisting microscope: A new lens on quantum materials
(via sciencedaily.com) One of the striking aspects of the quantum world is that a particle, say, an electron, is also a wave, meaning that it exists in many places at the same time. Researchers make use of this property to develop a new type of tool -- the quantum twisting microscope (QTM) -- that can create novel quantum materials while simultaneously gazing into the most fundamental quantum nature of their electrons.
Published Ramping up domestic graphite production could aid the green energy transition
(via sciencedaily.com) Given the growing importance of graphite in energy storage technologies, a team of esearchers has conducted a study exploring ways to reduce reliance on imports of the in high-demand mineral, which powers everything from electric vehicles (EVs) to cell phones.
Published Smooth sailing for electrons in graphene
(via sciencedaily.com) Physicists have directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results have applications in developing new, low-resistance materials, where electrical transport would be more efficient.
