Published Could microplastics in soil introduce drug-resistant superbugs to the food supply?
(via sciencedaily.com) Original source A new review argues ever-present microplastics could promote gene transfer among microbes, potentially resulting in greater antibiotic resistance. The review calls for more research on microplastic-microbe interactions where our food is grown.
Published Hot chemistry quickly transforms aromatic molecules into harmful aerosols
(via sciencedaily.com) A research group has established key early steps in the conversion of aromatic molecules, a major constituent of traffic and other urban volatile emissions, into aerosol. Their findings increase understanding of the chemical processes that degrade urban air quality and influence climate change.
Published Scientists develop fermionic quantum processor
(via sciencedaily.com) Researchers have designed a new type of quantum computer that uses fermionic atoms to simulate complex physical systems. The processor uses programmable neutral atom arrays and is capable of simulating fermionic models in a hardware-efficient manner using fermionic gates. The team demonstrated how the new quantum processor can efficiently simulate fermionic models from quantum chemistry and particle physics.
Published Biologist gets the scoop on squash bug poop
(via sciencedaily.com) Original source A discovery about how a common insect acquires a microbe that is essential for its growth may help in the control of an agricultural pest.
Published Fungus gnats as pollinators not pests
(via sciencedaily.com) Original source Many plants and crops rely on insects to pollinate them so they can reproduce. A new study has shown that several flowering plants from the group Euonymus are pollinated by fungus gnats, a dipteran insect. Specifically, they pollinate Euonymus plants which have red-petaled flowers with short stamens and yogurt-like scent. Although fungus gnats are known to pollinate hundreds of plant species, this study shows that the particular traits of red Euonymus flowers were likely to have been acquired via pollination syndrome, evolving over a process of natural selection to be pollinated specifically by fungus gnats. This research highlights the important role of Diptera, which are commonly regarded as pests, in plant diversity and evolution.
Published Steam condenser coating could save 460M tons of CO2 annually
(via sciencedaily.com) If coal and natural gas power generation were 2% more efficient, then, every year, there could be 460 million fewer tons of carbon dioxide released and 2 trillion fewer gallons of water used. A recent innovation to the steam cycle used in fossil fuel power generation could achieve this.
Published New antibiotic from microbial 'dark matter' could be powerful weapon against superbugs
(via sciencedaily.com) Original source A new powerful antibiotic, isolated from bacteria that could not be studied before, seems capable of combating harmful bacteria and even multi-resistant 'superbugs'. Named Clovibactin, the antibiotic appears to kill bacteria in an unusual way, making it more difficult for bacteria to develop any resistance against it.
Published High-fat diets alter gut bacteria, boosting colorectal cancer risk in mice
(via sciencedaily.com) Original source Researchers have discovered how high-fat diets can change gut bacteria and alter digestive molecules called bile acids that are modified by those bacteria, predisposing mice to colorectal cancer. The findings bring scientists closer to understanding the causes of and how to prevent colorectal cancer.
Published The trio -- nickel, palladium, and platinum -- for enhanced hydrogen evolution
(via sciencedaily.com) A research team enhanced hydrogen evolution catalyst through stepwise deposition.
Published Topology's role in decoding energy of amorphous systems
(via sciencedaily.com) Researchers used topological data analysis to improve the predictions of physical properties of amorphous materials by machine-learning algorithms. This may allow for cheaper and faster calculations of material properties.
Published New epoxy resin resists flames and reduces waste
(via sciencedaily.com) Researchers have developed an epoxy resin that can be repaired and recycled, in addition to being flame-retardant and mechanically strong. Potential applications range from coating for wooden flooring to composites in aerospace and railways.
Published Deciphering the molecular dynamics of complex proteins
(via sciencedaily.com) Which structures do complex proteins adopt in solution? Biophysicists answer this question using the example of ubiquitin dimers as well as a new combination of high-resolution NMR spectroscopy and sophisticated computer simulations.
Published Sharing chemical knowledge between human and machine
(via sciencedaily.com) Researchers have developed a platform that uses artificial neural networks to translate chemical structural formulae into machine-readable form. With this platform, they have created a tool with which this information from scientific publications can be automatically fed into databases. Until now, this had to be done literally by hand and was time-consuming.
Published New antifungal therapy for fungal meningitis
(via sciencedaily.com) Original source A team of researchers successfully tested a new antifungal therapy to treat fungal meningitis.
Published New approach shows hydrogen can be combined with electricity to make pharmaceutical drugs
(via sciencedaily.com) The world needs greener ways to make chemicals. In a new study, researchers demonstrate one potential path toward this goal by adapting hydrogen fuel cell technologies.
Published Research team developing a nano-sized force sensor and improving high-precision microscopy technology
(via sciencedaily.com) Recent research in cell biology highlights groundbreaking results. An international team of researchers have recently established a tool they developed to study the mechanics of the cell. The tool can be used to study the inner forces of the cell, for example, the stretching of the nuclear membrane. The microscopic force sensor, only about 0.00002 mm long, is constructed of exotic ingredients such as spider web protein parts, fluorescent proteins from jellyfish, and antibodies from alpaca. In addition, the multidisciplinary team of researchers has developed further the sensitivity of super-resolution microscopy technique.
Published 'Viral relicts' in the genome could fuel neurodegeneration
(via sciencedaily.com) Original source Genetic remnants of viruses that are naturally present in the human genome could affect the development of neurodegenerative diseases. Researchers come to this conclusion on the basis of studies on cell cultures.
Published Using big data on livestock farms could improve antimicrobial resistance surveillance
(via sciencedaily.com) Original source A new study suggests that using big data and machine learning in antimicrobial resistance (AMR) surveillance in livestock production methods could help inform interventions and offer protections against germs that are becoming resistant to antibiotics.
Published Demon hunting: Physicists confirm 67-year-old prediction of massless, neutral composite particle
(via sciencedaily.com) In 1956, theoretical physicist David Pines predicted that electrons in a solid can do something strange. While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle that is massless, neutral, and does not interact with light. He called this particle a 'demon.' Now, researchers have finally found Pines' demon 67 years after it was predicted.
Published Novel treatment based on gene editing safely and effectively removes HIV-like virus from genomes of non-human primates
(via sciencedaily.com) Original source A single injection of a novel CRISPR gene-editing treatment safely and efficiently removes SIV -- a virus related to the AIDS-causing agent HIV -- from the genomes of non-human primates, scientists now report. The groundbreaking work complements previous experiments as the basis for the first-ever clinical trial of an HIV gene-editing technology in human patients, which was authorized by the Food and Drug Administration (FDA) in 2022.
