Published Unraveling the drought dilemma: Can reservoirs be a carbon source?
(via sciencedaily.com) Original source A team delves into the spatiotemporal patterns of water volume and total organic carbon concentration of agricultural reservoirs.
Published U.S. drought-monitoring system outpaced by climate changes
(via sciencedaily.com) Original source A new study reports that the U.S. Drought Monitor's weekly maps of nationwide drought conditions -- which help direct emergency federal aid -- have captured the steady march of climate change, but the Drought Monitor has itself failed to adapt to that reality. Areas of the country are spending more and more time in severe drought conditions the Drought Monitor still considers to be rare occurrences. The consequences could be that swaths of the country -- particularly in the West -- may not receive aid in keeping with the enhanced risk of drought as periodic emergencies become persistent new realities.
Published Record low Antarctic sea ice 'extremely unlikely' without climate change
(via sciencedaily.com) Original source Scientists have found that the record-low levels of sea ice around Antarctica in 2023 were extremely unlikely to happen without the influence of climate change. This low was a one-in-a-2000-year event without climate change and four times more likely under its effects.
Published Ion irradiation offers promise for 2D material probing
(via sciencedaily.com) Original source Two-dimensional materials such as graphene promise to form the basis of incredibly small and fast technologies, but this requires a detailed understanding of their electronic properties. New research demonstrates that fast electronic processes can be probed by irradiating the materials with ions first.
Published Magnetic imprint on deconfined nuclear matter
(via sciencedaily.com) Original source Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the collisions. The study provides proof that the magnetic fields exist and offers a new way to measure electrical conductivity in quark-gluon plasma.
Published Diamond glitter: A play of colors with artificial DNA crystals
(via sciencedaily.com) Original source Using DNA origami, researchers have built a diamond lattice with a periodicity of hundreds of nanometers -- a new approach for manufacturing semiconductors for visible light.
Published Climate change likely to aggravate brain conditions
(via sciencedaily.com) Original source Climate change, and its effects on weather patterns and adverse weather events, is likely to negatively affect the health of people with brain conditions, argue a team of researchers.
Published Studying bubbles can lead to more efficient biofuel motors
(via sciencedaily.com) Original source By studying how bubbles form in a drop of biodiesel, researchers can help future engines get the most energy out of the fuel.
Published Researchers use artificial intelligence to boost image quality of metalens camera
(via sciencedaily.com) Original source Researchers have leveraged deep learning techniques to enhance the image quality of a metalens camera. The new approach uses artificial intelligence to turn low-quality images into high-quality ones, which could make these cameras viable for a multitude of imaging tasks including intricate microscopy applications and mobile devices.
Published A simple quantum internet with significant possibilities
(via sciencedaily.com) Original source It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's possible. That's exactly what physicists have done, using existing Boston-area telecommunication fiber, in a demonstration of the world's longest fiber distance between two quantum memory nodes to date.
Published Bio-based resins could offer recyclable future for 3D printing
(via sciencedaily.com) Original source A new type of recyclable resin, made from biosourced materials, has been designed for use in 3D printing applications.
Published 90% of Floridians believe climate change is happening
(via sciencedaily.com) Original source The latest 'Florida Climate Resilience Survey' found that 90% of Floridians believe that climate change is happening. Belief in human-caused climate change has surged among Florida Independents while slipping among Republicans in the state since last fall. But despite these changes, the survey found enduring support among Floridians for increased government action to address the consequences of a warming planet. The survey found 68% of all respondents want state government to do more and 69% want the federal government to do more to address climate change.
Published Metalens expands Its reach from light to sound
(via sciencedaily.com) Original source Engineers achieve a wide field-of-hearing acoustic metalens free from aberrations.
Published Scientists create an 'optical conveyor belt' for quasiparticles
(via sciencedaily.com) Original source Using interference between two lasers, a research group has created an 'optical conveyor belt' that can move polaritons -- a type of light-matter hybrid particle -- in semiconductor-based microcavities. This work could lead to the development of new devices with applications in areas such as quantum metrology and quantum information.
Published Speedy, secure, sustainable -- that's the future of telecom
(via sciencedaily.com) Original source A new device that can process information using a small amount of light could enable energy-efficient and secure communications.
Published 2023 was the hottest summer in two thousand years
(via sciencedaily.com) Original source Researchers have found that 2023 was the hottest summer in the Northern Hemisphere in the past two thousand years, almost four degrees warmer than the coldest summer during the same period.
Published Milestone in plasma acceleration
(via sciencedaily.com) Original source Scientists have made a significant advance in laser plasma acceleration. By employing an innovative method, a research team managed to substantially exceed the previous record for proton acceleration. For the first time, they achieved energies that so far have only seemed possible at much larger facilities. As the research group reported, promising applications in medicine and materials science have now become much likelier.
Published Good vibrations: New tech may lead to smaller, more powerful wireless devices
(via sciencedaily.com) Original source What if your earbuds could do everything your smartphone can, but better? A new class of synthetic materials could allow for smaller devices that use less power.
Published Take cover! Survey shows tornado warnings widely misunderstood
(via sciencedaily.com) Original source A study showed that about half of those surveyed in the mid-South could not accurately identify a tornado warning.
Published Improved wildfire smoke model identifies areas for public health intervention
(via sciencedaily.com) Original source The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.
