Published Cocaine trafficking threatens critical bird habitats
(via sciencedaily.com) Original source In addition to its human consequences, cocaine trafficking harms the environment and threatens habitats important to dozens of species of migratory birds, according to a new study.
Published Humans are the elephant in the room where conservation is debated
(via sciencedaily.com) Original source Studies working to map conservation historically have left humans out of the equation. This study proposes ways to build in the outsized footprint created by people in wild places.
Published Uncovering the nature of emergent magnetic monopoles
(via sciencedaily.com) Original source To understand the unique physical phenomena associated with the properties of magnetic hedgehogs and antihedgehogs, which behave as virtual magnetic monopoles and antimonopoles respectively, it is essential to study their intrinsic excitations. In a new study, researchers revealed the dynamical nature of collective excitation modes in hedgehog lattices in itinerant chiral magnets. Their findings serve as the foundation for studying the dynamics of emergent magnetic monopoles in magnets.
Published Just thinking about a location activates mental maps in the brain
(via sciencedaily.com) Original source Researchers found that mental representations known as cognitive maps, located in the hippocampus and entorhinal cortex, are activated when the brain performs mental simulations of a navigational route.
Published Significant increase in nitrous-oxide emissions from human activities, jeopardizing climate goals
(via sciencedaily.com) Original source Emissions of nitrous-oxide (N2O) -- a potent greenhouse gas -- have continued to rise unabated over the past four decades, according to an international team of scientists.
Published New technique could help build quantum computers of the future
(via sciencedaily.com) Original source Researchers have demonstrated a new method that could enable the large-scale manufacturing of optical qubits. The advance could bring us closer to a scalable quantum computer.
Published Switching nanomagnets using infrared lasers
(via sciencedaily.com) Original source Physicists have calculated how suitable molecules can be stimulated by infrared light pulses to form tiny magnetic fields. If this is also successful in experiments, the principle could be used in quantum computer circuits.
Published Researchers use 3D visualization to predict, prevent hurricane damage
(via sciencedaily.com) Original source The researchers say 3D visualization of hurricanes and storm surges allows them to understand how flooding will impact coastal communities by allowing them to vividly see how each building and road might be impacted by a given flood.
Published Upstream and downstream: River study highlights cross-country inequities
(via sciencedaily.com) Original source New research highlights inequities between downstream and upstream countries that share the same watershed. The study outlines how international agreements can better address shared resource problems and call for greater collaboration and coordination between these international neighbors.
Published Study estimates that between 1980 and 2020, 135 million premature deaths could be linked to fine particulate matter pollution
(via sciencedaily.com) Original source A study has revealed that fine particulate matter from 1980 to 2020 was associated with approximately 135 million premature deaths globally.
Published 'Quantum optical antennas' provide more powerful measurements on the atomic level
(via sciencedaily.com) Original source A multi-institutional team has created atomic optical antennas in solids. The team used germanium vacancy centers in diamonds to create an optical energy enhancement of six orders of magnitude, a regime challenging to reach with conventional atomic antenna structures.
Published Cascadia Subduction Zone, one of Earth's top hazards, comes into sharper focus
(via sciencedaily.com) Original source A new study has produced the first comprehensive survey of the many complex structures beneath the seafloor in the Cascadia Subduction Zone, off British Columbia, Washington, Oregon and California. It is providing scientists with key insights into how future disasters may unfold.
Published Perturbations simplify the study of 'super photons'
(via sciencedaily.com) Original source Thousands of particles of light can merge into a type of 'super photon' under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access.
Published Earth and space share the same turbulence
(via sciencedaily.com) Original source Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.
Published Diagnosing damaged infrastructure from space
(via sciencedaily.com) Original source Synthetic Aperture Radar (SAR) remote sensing systems allow researchers to inspect and characterize pavements, retaining walls, and embankments from space and can help determine if there are flaws that should be further inspected for repair.
Published Novel diamond quantum magnetometer for ambient condition magnetoencephalography
(via sciencedaily.com) Original source A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG). The novel magnetometer, based on continuous-wave optically detected magnetic resonance, marks a significant step towards realizing ambient condition MEG and other practical applications.
Published Scientists question effectiveness of nature-based CO2 removal using the ocean
(via sciencedaily.com) Original source Limited understanding of basic ocean processes is hindering progress in marine carbon dioxide removal, with the on-going commercialization of some approaches 'premature and misguided'. Scientists now review the climatic effectiveness of four 'nature-based' techniques using marine biological processes. These involve shellfish cultivation, seaweed farming, coastal blue carbon -- using the restoration of seagrass, saltmarsh and mangrove forests -- and increasing whale populations through 're-wilding'.
Published Fighting fires from space in record time: How AI could prevent devastating wildfires
(via sciencedaily.com) Original source Scientists are getting closer to detecting bushfires in record time, thanks to cube satellites with onboard AI now able to detect fires from space 500 times faster than traditional on-ground processing of imagery.
Published Early summer fishing can have an evolutionary impact, resulting in smaller salmon
(via sciencedaily.com) Original source A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon. This information can help to conserve large fish essential for the diversity and viability of salmon populations.
Published A novel approach to tracking conservation reveals more areas may be conserved than currently accounted for
(via sciencedaily.com) Original source An international team of conservation researchers and practitioners has developed an inclusive inventory approach for tracking global conservation areas, with an emphasis on local data and expertise. Applying this approach across the nine countries spanning the Amazon Rainforest identified a wide array of conservation areas with greater diversity and area coverage than existing tracking systems showed.
