Published New findings offer potential breakthrough in HIV cure research
(via sciencedaily.com) Original source The results of a novel study has revealed exciting findings in the pursuit of an HIV cure.
Published Western science catches up with First Nations' medicinal use of ant honey
(via sciencedaily.com) Original source Scientists have discovered the honey produced by Australian ants possesses unique anti-microbial activity against bacteria and fungi that could make the liquid useful medicinally.
Published A new type of quantum bit in semiconductor nanostructures
(via sciencedaily.com) Researchers have created a quantum superposition state in a semiconductor nanostructure that might serve as a basis for quantum computing. The trick: two optical laser pulses that act as a single terahertz laser pulse.
Published Monkeypox: Characterization of post-infectious immune response
(via sciencedaily.com) Original source In 2022-2023, an outbreak of monkeypox, now known as mpox (caused by the monkeypox virus or MPXV) led to 87,000 human cases in 170 countries. Most cases were reported outside the usual areas in which the virus circulates. Since the outbreak began, surveillance of the virus has been stepped up in Europe, with nearly 5,000 cases being reported in France.
Published 'Quantum avalanche' explains how nonconductors turn into conductors
(via sciencedaily.com) Original source The study takes a new approach to answer a long-standing mystery about insulator-to-metal transitions.
Published Study explores how often children diagnosed with flu experience serious neuropsychiatric side effects
(via sciencedaily.com) Original source While the incidence of influenza-associated neuropsychiatric events in children in the United States is unknown, the controversy over the use of a common antiviral medication typically administered to treat flu in children has sparked concern among parents and medical professionals alike.
Published Revealing HIV drug-resistance mechanisms through protein structures
(via sciencedaily.com) Original source Researchers have discovered the molecular mechanisms by which the human immunodeficiency virus (HIV) becomes resistant to Dolutegravir, one of the most effective, clinically used antiviral drugs for treating HIV. Their findings reveal how changes to the 3D structures of integrase, an HIV protein, can lead to Dolutegravir resistance and how other compounds may be able to overcome this resistance.
Published Detection of bacteria and viruses with fluorescent nanotubes
(via sciencedaily.com) The new carbon nanotube sensor design resembles a molecular toolbox that can be used to quickly assemble sensors for a variety of purposes -- for instance for detecting bacteria and viruses.
Published Some people's brain function still affected by Long COVID years after infection
(via sciencedaily.com) Original source Researchers have found that people with longer-term COVID-19 symptoms including brain fog showed reduced performance in tasks testing different mental processes up to two years after infection with the virus.
Published Scientists develop AI-based tracking and early-warning system for viral pandemics
(via sciencedaily.com) Original source Machine-learning system effectively predicts emergence of prominent variants.
Published Fueled by new chemistry, algorithm mines fungi for useful molecules
(via sciencedaily.com) Original source A newly described type of chemistry in fungi is both surprisingly common and likely to involve highly reactive enzymes, two traits that make the genes involved useful signposts pointing to a potential treasure trove of biological compounds with medical and chemical applications. It was also nearly invisible to scientists until now.
Published Unveiling the quantum dance: Experiments reveal nexus of vibrational and electronic dynamics
(via sciencedaily.com) Scientists have demonstrated experimentally a long-theorized relationship between electron and nuclear motion in molecules, which could lead to the design of materials for solar cells, electronic displays and other applications that can make use of this powerful quantum phenomenon.
Published Gene mutation may explain why some don't get sick from COVID-19
(via sciencedaily.com) Original source People who contract COVID-19 but never develop symptoms -- the so-called super dodgers -- may have a genetic ace up their sleeve. They're more than twice as likely as those who become symptomatic to carry a specific gene variation that helps them obliterate the virus, according to a new study.
Published 'Mind controlling' parasitic worms are missing genes found in every other animal
(via sciencedaily.com) Original source Parasitic hairworms manipulate the behavior of their hosts in what's sometimes called 'mind control.' A new study reveals another strange trait shared by different hairworm species: they're missing about 30% of the genes that researchers expected them to have. What's more, the missing genes are responsible for the development of cilia, the hair-like structures present in at least some of the cells of every other animal known.
Published Theory for superfluid helium confirmed
(via sciencedaily.com) Researchers have achieved a groundbreaking milestone in studying how vortices move in these quantum fluids. A new study of vortex ring motion in superfluid helium provides crucial evidence supporting a recently developed theoretical model of quantized vortices.
Published Researchers establish criterion for nonlocal quantum behavior in networks
(via sciencedaily.com) A new theoretical study provides a framework for understanding nonlocality, a feature that quantum networks must possess to perform operations inaccessible to standard communications technology. By clarifying the concept, researchers determined the conditions necessary to create systems with strong, quantum correlations.
Published New superconductors can be built atom by atom
(via sciencedaily.com) The future of electronics will be based on novel kinds of materials. Sometimes, however, the naturally occurring topology of atoms makes it difficult for new physical effects to be created. To tackle this problem, researchers have now successfully designed superconductors one atom at a time, creating new states of matter.
Published Despite doubts from quantum physicists: Einstein's theory of relativity reaffirmed
(via sciencedaily.com) Original source One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all measurements to date confirm the equivalence principle, quantum theory postulates that there should be a violation. This inconsistency between Einstein's gravitational theory and modern quantum theory is the reason why ever more precise tests of the equivalence principle are particularly important. A team has now succeeded in proving with 100 times greater accuracy that passive and active gravitational mass are always equivalent -- regardless of the particular composition of the respective masses.
Published Controlling signal routing in quantum information processing
(via sciencedaily.com) Original source Routing signals and isolating them against noise and back-reflections are essential in many practical situations in classical communication as well as in quantum processing. In a theory-experimental collaboration, a team has achieved unidirectional transport of signals in pairs of 'one-way streets'. This research opens up new possibilities for more flexible signaling devices.
Published Fungi blaze a trail to fireproof cladding
(via sciencedaily.com) Original source Scientists have shown it's possible to grow fungi in thin sheets that could be used for fire-retardant cladding or even a new kind of fungal fashion.
