Published Hailstone library to improve extreme weather forecasting
(via sciencedaily.com) Original source Researchers are measuring and scanning samples for a global 'hailstone library'. Storm simulations using 3-D modelling of real hailstones -- in all sorts of weird shapes from oblong to flat discs or with spikes coming out -- show it behaves differently than spherical hail shapes. Data from the hail library could lead to more accurate storm forecasts.
Published Large Hadron Collider pipe brings search for elusive magnetic monopole closer than ever
(via sciencedaily.com) Original source New research using a decommissioned section of the beam pipe from the Large Hadron Collider (LHC) at CERN has bought scientists closer than ever before to test whether magnetic monopoles exist. Scientists have revealed the most stringent constraints yet on the existence of magnetic monopoles, pushing the boundaries of what is known about these elusive particles.
Published New research shows unprecedented atmospheric changes during May's geomagnetic superstorm
(via sciencedaily.com) Original source On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.
Published Researchers observe 'locked' electron pairs in a superconductor cuprate
(via sciencedaily.com) Original source The finding could help future efforts to design superconductors that work at higher temperatures.
Published New insight Into behavior of electrons
(via sciencedaily.com) Original source Physicists have uncovered new states of matter by exploring the behavior of flatland electrons in extreme conditions, revealing insights that could impact quantum computing and advanced materials.
Published Quantum pumping in molecular junctions
(via sciencedaily.com) Original source Researchers have developed a new theoretical modelling technique that could potentially be used in the development of switches or amplifiers in molecular electronics.
Published Advancing modular quantum information processing
(via sciencedaily.com) Original source A team of physicists envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations. The ability to carry out such correlated or 'entangling' operations between linked qubits is the basis of the enhanced power quantum computing holds compared with current computers.
Published Physicists throw world's smallest disco party
(via sciencedaily.com) Original source A new milestone has been set for levitated optomechanics as a group of scientists observed the Berry phase of electron spins in nano-sized diamonds levitated in vacuum.
Published Hydrometeorology and location affect hospitalizations for waterborne infectious diseases in the US
(via sciencedaily.com) Original source An analysis of 12 years of data collected from over 500 hospitals in 25 different states shows that weather, geographic location, and urban or rural location all appear to influence hospitalizations for waterborne infectious diseases.
Published Tropical Atlantic mixing rewrites climate pattern rules
(via sciencedaily.com) Original source Changes in the Atlantic Ocean's mixed layer are the primary force behind the Atlantic Multidecadal Variability (AMV).
Published A method that paves the way for improved fuel cell vehicles
(via sciencedaily.com) Original source More efficient and longer-lasting fuel cells are essential for fuel cell-powered heavy-duty hydrogen vehicles to be an alternative to combustion fuelled counterparts. Researchers have developed an innovative method to study and understand how parts of fuel cells degrade over time. This is an important step towards the improved performance of fuel cells and them becoming commercially successful.
Published Nighttime light data shows inequities in restoring power after Hurricane Michael
(via sciencedaily.com) Original source Using nighttime lightdata from NASA, remote sensing, official outage records and census information, a study reveals notable differences in power-restoration rates between urbanized and rural areas and between disadvantaged and more affluent communities after Hurricane Michael in Florida's Panhandle. Block groups with higher proportions of minorities, multi-family housing units, rural locations, and households receiving public assistance experienced slower restoration of power compared to urban and more affluent neighborhoods.
Published Climate change raised the odds of unprecedented wildfires in 2023-24
(via sciencedaily.com) Original source Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.
Published Study reveals urban trees suffer more from heat waves and drought than their rural counterparts
(via sciencedaily.com) Original source A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.
Published Breakthrough in nanotechnology: Viewing the invisible with advanced microscopy
(via sciencedaily.com) Original source Scientists have made a groundbreaking discovery in the field of nanotechnology. They have developed a novel microscopy method that allows for the unprecedented visualization of nanostructures and their optical properties.
Published The mother of all motion sensors
(via sciencedaily.com) Original source Researchers have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable.
Published New study unveils 16,000 years of climate history in the tropical Andes
(via sciencedaily.com) Original source Researchers highlight the roles of carbon dioxide and ocean currents as key drivers of temperature fluctuations in the tropical Andes over a 16,000 year period.
Published How mortal filaments' self-assemble and maintain order: Align or die
(via sciencedaily.com) Original source A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto 'dying to align': Misaligned filaments 'die' spontaneously to form a ring structure at the center of the dividing cell. The work could find applications in developing synthetic self-healing materials.
