Published Scientists warn of rise in potentially fatal bacterial infection due to global warming
(via sciencedaily.com) Continued warming of the climate would see a rise in the number and spread of potentially fatal infections caused by bacteria found along parts of the coast of the United States. Vibrio vulnificus bacteria grow in warm shallow coastal waters and can infect a cut or insect bite during contact with seawater. The researchers predict that by 2041--2060 infections may spread to encompass major population centers around New York. Combined with a growing and increasingly elderly population, who are more susceptible to infection, annual case numbers could double.
Published Known active ingredient as new drug candidate against mpox
(via sciencedaily.com) Mpox -- previously known as 'monkeypox' -- is currently spreading worldwide. Researchers have now identified a compound that could help fight the disease.
Published Memory B cell marker predicts long-lived antibody response to flu vaccine
(via sciencedaily.com) Memory B cells play a critical role to provide long-term immunity after a vaccination or infection. Researchers have now described a distinct and novel subset of memory B cells that predict long-lived antibody responses to influenza vaccination in humans. These effector memory B cells appear to be poised for a rapid serum antibody response upon secondary challenge one year later.
Published Hidden 'super spreaders' spur dengue fever transmission
(via sciencedaily.com) For mosquito-borne diseases such as dengue fever, the abundance of the insects in places where people gather has long served as the main barometer for infection risk. A new study, however, suggests that the number of 'hidden' infections tied to a place, or cases of infected people who show no symptoms, is the key indicator for dengue risk.
Published Sea otters killed by unusual parasite strain
(via sciencedaily.com) An unusually severe form of toxoplasmosis killed four sea otters and could pose a threat to other marine wildlife and humans, finds a new study.
Published Photosynthesis 'hack' could lead to new ways of generating renewable energy
(via sciencedaily.com) Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to new ways of generating clean fuel and renewable energy.
Published Semiconductor lattice marries electrons and magnetic moments
(via sciencedaily.com) A model system created by stacking a pair of monolayer semiconductors is giving physicists a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.
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 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 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 Synthesis gas and battery power from sunlight energy
(via sciencedaily.com) Plants use photosynthesis to harvest energy from sunlight. Now researchers have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.
Published Visualization of electron dynamics on liquid helium
(via sciencedaily.com) An international team has discovered how electrons can slither rapidly to-and-fro across a quantum surface when driven by external forces. The research has enabled the visualization of the motion of electrons on liquid helium.
Published 'Y-ball' compound yields quantum secrets
(via sciencedaily.com) Scientists investigating a compound called 'Y-ball' -- which belongs to a mysterious class of 'strange metals' viewed as centrally important to next-generation quantum materials -- have found new ways to probe and understand its behavior.
Published Batteries: Passivation layer mystery solved
(via sciencedaily.com) In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.
Published Surprise in the quantum world: Disorder leads to ferromagnetic topological insulator
(via sciencedaily.com) Magnetic topological insulators are an exotic class of materials that conduct electrons without any resistance at all and so are regarded as a promising breakthrough in materials science. Researchers have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing the ferromagnetic topological insulator MnBi6Te10 from the manganese bismuth telluride family. The amazing thing about this quantum material is that its ferromagnetic properties only occur when some atoms swap places, introducing antisite disorder.
Published 'Inkable' nanomaterial promises big benefits for bendable electronics
(via sciencedaily.com) An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight and bendable displays and devices.
Published High-energy-density, long life-cycle rechargeable lithium metal batteries
(via sciencedaily.com) Research shows promise for developing high-energy-density rechargeable lithium-metal batteries and addressing the electrochemical oxidation instability of ether-based electrolytes.
Published Emergence of extensively drug-resistant Shigella sonnei strain in France
(via sciencedaily.com) Shigellosis, a highly contagious diarrheal disease, is caused by Shigella bacteria circulating in industrializing countries but also in industrialized countries. Scientists who have been monitoring Shigella in France for several years have detected the emergence of extensively drug-resistant (XDR) strains of Shigella sonnei.
Published First detection of neutrinos made at a particle collider
(via sciencedaily.com) A team including physicists has for the first time detected subatomic particles called neutrinos created by a particle collider, namely at CERN's Large Hadron Collider (LHC). The discovery promises to deepen scientists' understanding of the nature of neutrinos, which are among the most abundant particles in the universe and key to the solution of the question why there is more matter than antimatter.
