Published Generating stable qubits at room temperature
(via sciencedaily.com) Original source Quantum bits, or qubits, can revolutionize computing and sensing systems. However, cryogenic temperatures are required to ensure the stability of qubits. In a groundbreaking study, researchers observed stable molecular qubits of four electron spins at room temperature for the first time by suppressing the mobility of a dye molecule within a metal-organic framework. Their innovative molecular design opens doors to materials that could drive the development of quantum technologies capable of functioning in real-world conditions.
Published Experiments in infant mice suggest new way to prevent spread of flu in people
(via sciencedaily.com) Original source Scientists have long known that some viruses and bacteria begin infections by latching first onto sugar molecules on the surfaces of cells lining the sinuses and throat of mammals, including humans. Viral particles, for instance, can attach to these molecules, called sialic acids, or SAs, like keys fitting into locks.
Published First direct imaging of small noble gas clusters at room temperature
(via sciencedaily.com) Original source Scientists have succeeded in the stabilization and direct imaging of small clusters of noble gas atoms at room temperature. This achievement opens up exciting possibilities for fundamental research in condensed matter physics and applications in quantum information technology. The key to this breakthrough was the confinement of noble gas atoms between two layers of graphene.
Published Toxic algae blooms: Study assesses potential health hazards to humans
(via sciencedaily.com) Original source Water samples from 20 sites were tested using a panel of immortalized human cell lines corresponding to the liver, kidney and brain to measure cytotoxicity. Results show that each control toxin induced a consistent pattern of cytotoxicity in the panel of human cell lines assayed. Known toxins were seen only during blooms. Because cell toxicity was seen in the absence of blooms, it suggests that there might be either emergent toxins or a combination of toxins present at those times. Findings suggest that other toxins with the potential to be harmful to human health may be present in the lagoon.
Published A new type of plant metalloreductase maintains root growth under low phosphorus
(via sciencedaily.com) Original source Phosphorus is essential for undisturbed plant growth and development. However, in many soils, phosphorus is only poorly available. One mechanism used by plants to increase phosphorus availability is the release of malate, an organic acid, which can form complexes with iron or aluminium in the soil, thereby liberating sorbed phosphate. However, this response can also result in iron overaccumulation, which can inhibit root growth.
Published Study on lamprey embryos sheds light on the evolutionary origin of vertebrate head
(via sciencedaily.com) Original source Scientists have investigated lamprey embryos using cutting-edge microscopic techniques to reveal interesting insights about vertebrate head evolution, clarifying an unresolved mystery in basic science.
Published Plant warfare: The crucial function of Nrc proteins in tomato defense mechanisms
(via sciencedaily.com) Original source New research delves into the intricate defense mechanisms of tomatoes against the notorious bacterial pathogen, Pseudomonas syringae pv. tomato (Pst). It's a classic tale of nature's arms race: as pathogens evolve to outsmart plant defenses, plants counter with more sophisticated immune responses.
Published With only the pawprints, researchers study elusive bobcat
(via sciencedaily.com) Original source With DNA recovered from animal tracks, scientists revealed information about the ancestry and microbial community of bobcats without having to sample the animal directly.
Published Researchers demonstrate that quantum entanglement and topology are inextricably linked
(via sciencedaily.com) Original source Researchers have demonstrated the remarkable ability to perturb pairs of spatially separated yet interconnected quantum entangled particles without altering their shared properties.
Published Smart skin bacteria are able to secrete and produce molecules to treat acne
(via sciencedaily.com) Original source An experimental study has shown that a type of skin bacterium can efficiently be engineered to produce a protein to regulate sebum production. This application could treat acne without compromising the homeostasis of the entire skin microbiome.
Published Stranger than friction: A force initiating life
(via sciencedaily.com) Original source As the potter works the spinning wheel, the friction between their hands and the soft clay helps them shape it into all kinds of forms and creations. In a fascinating parallel, sea squirt oocytes (immature egg cells) harness friction within various compartments in their interior to undergo developmental changes after conception.
Published New study uses machine learning to bridge the reality gap in quantum devices
(via sciencedaily.com) Original source A study has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the 'reality gap': the difference between predicted and observed behavior from quantum devices.
Published Large-scale mapping of pig genes could pave the way for new human medicines
(via sciencedaily.com) Original source Researchers have carried out complex genetic analyses of hundreds of pigs and humans to identify differences and similarities. This new knowledge can be used to ensure healthier pigs for farmers and can help the pharmaceutical industry breed better laboratory pigs for testing new medicines.
Published Life span increases in mice when specific brain cells are activated
(via sciencedaily.com) Original source A new study identifies, in mice, a critical communication pathway connecting the brain and the body's fat tissue in a feedback loop that appears central to energy production throughout the body. The research suggests that the gradual deterioration of this feedback loop contributes to the increasing health problems that are typical of natural aging.
Published Researchers discover molecular 'barcode' used by bacteria to secrete toxins
(via sciencedaily.com) Original source Researchers have discovered a molecular 'barcode' system used by disease-causing bacteria to distinguish between beneficial and toxic molecules.
Published Researchers develop algorithm to determine how cellular 'neighborhoods' function in tissues
(via sciencedaily.com) Original source Researchers have developed a new AI-powered algorithm to help understand how different cells organize themselves into particular tissues and communicate with one another.
Published Important membrane transport mechanism in pathogenic bacteria
(via sciencedaily.com) Original source Some bacterial membrane transporters work almost like freight elevators to transport substances through the cell membrane into the interior of the cell. The transporter itself spans the bacterial membrane. Like a forklift, a soluble protein outside the bacterium transports the substance to the 'elevator' and unloads its cargo there. The freight elevator transports it to the inside of the cell, in other words to another floor.
Published A novel strategy for extracting white mycelial pulp from fruiting mushroom bodies
(via sciencedaily.com) Original source Mycelial fibers, the fibrous cells found in fruiting mushroom bodies, have gained momentum as a sustainable material for making faux-leather and packaging owing to their excellent formability. Recently, a team of researchers has found a simple way of obtaining mycelial fibers, called 'mycelial pulp,' from fruiting mushroom bodies and bleaching them using sunlight while keeping their mycelial structures intact.
Published A new approach can address antibiotic resistance to Mycobacterium abscessus
(via sciencedaily.com) Original source Scientists have created analogs of the antibiotic spectinomycin that are significantly more effective against these highly resistant bacteria.
Published Engineers invent octopus-inspired technology that can deceive and signal
(via sciencedaily.com) Original source With a split-second muscle contraction, the greater blue-ringed octopus can change the size and color of the namesake patterns on its skin for purposes of deception, camouflage and signaling. Researchers have drawn inspiration from this natural wonder to develop a technological platform with similar capabilities for use in a variety of fields, including the military, medicine, robotics and sustainable energy.
