Published Ultrathin nanotech promises to help tackle antibiotic resistance
(via sciencedaily.com) Researchers have invented a nano-thin superbug-slaying material that could one day be integrated into wound dressings and implants to prevent or heal bacterial infections. The innovation -- which has undergone advanced pre-clinical trials -- is effective against a broad range of drug-resistant bacterial cells, including 'golden staph', which are commonly referred to as superbugs.
Published Movement sensors can detect disease in wild boar
(via sciencedaily.com) Original source Accelerometers reading the behavior of wild boars can pick up when animals are infected with a fatal virus.
Published Gotcha! New technology speeds up bacterial testing in food
(via sciencedaily.com) Researchers have developed a measurement technique that rapidly measures the number of viable bacteria in food products. They have succeeded in drastically reducing the inspection time from 2 days to about 1 hour. With this technology, it will be possible to confirm food safety before shipment from factories and prevent food poisoning.
Published You can leave your gloves on: New material burns viruses, safe for skin
(via sciencedaily.com) A new material that packs deadly heat for viruses on its outer surface while staying cool on the reverse side could be used to make sustainable, multiuse personal protective equipment.
Published Super antifreeze in cells: The ability to survive in ice and snow developed in animals far earlier than we thought
(via sciencedaily.com) Original source More than 400 million years ago, an insect-like animal called the springtail developed a small protein that prevents its cells from freezing.
Published Researcher helps boost immune system memory against influenza
(via sciencedaily.com) Original source Researchers are one step closer to making the T cell army stronger. In a recent study, researchers found that by manipulating one molecular signaling pathway in the T cells that participate in clearing influenza virus in the lungs, the strength and longevity of immunological memory produced can be improved.
Published Malaria-causing parasites resistant to both treatment and detection have emerged in Ethiopia
(via sciencedaily.com) Original source Genomic surveillance has revealed mutations in malaria-causing parasites that will complicate efforts to eradicate the disease in Africa.
Published 'A crab is never just a crab'
(via sciencedaily.com) Original source A herring in the North Sea, a crab in the Wadden Sea or an anemone fish on a coral reef, ... biologists like to think in terms of individual species that all have their own place within food webs in ecosystems across the world. 'But that is surely too simplistic thinking,' researchers warn.
Published Nutrients drive cellular reprogramming in the intestine
(via sciencedaily.com) Original source Researchers have unveiled an intriguing phenomenon of cellular reprogramming in mature adult organs, shedding light on a novel mechanism of adaptive growth. The study, which was conducted on fruit flies (Drosophila), provides further insights into dedifferentiation -- where specialized cells that have specific functions transform into less specialized, undifferentiated cells like stem cells.
Published Bacteria generate electricity from wastewater
(via sciencedaily.com) In a breakthrough for the field of bioelectronics, researchers have enhanced the ability of E. coli bacteria to generate electricity. The innovative approach only offers a sustainable solution for organic waste processing while outperforming previous state-of-the-art technologies, opening new horizons for versatile microbial electricity production.
Published Artificial intelligence could help build pollen jigsaw of present and ancient flora
(via sciencedaily.com) Original source An emerging system which combines rapid imaging with artificial intelligence could help scientists build a comprehensive picture of present and historic environmental change -- by swiftly and accurately analyzing pollen.
Published New at-home test for gingivitis protects oral health
(via sciencedaily.com) Original source Engineers have developed a new device that can warn consumers about early risks of tooth decay from diseases such as gingivitis and periodontitis.
Published How to prevent biofilms in space
(via sciencedaily.com) Original source In experiments aboard the International Space Station, a surface treatment developed engineers prevented the growth of microbial biofims. These films can damage equipment and potentially cause illness.
Published Fiber from crustaceans, insects, mushrooms promotes digestion
(via sciencedaily.com) Original source Crustaceans, insects and mushrooms are rich sources of the dietary fiber chitin, which activates the immune system and benefits metabolism, according to a new study in mice.
Published Dog diversity unveiled by international DNA database
(via sciencedaily.com) Original source An international consortium of scientists is using an unprecedentedly large database of canine DNA to take an unbiased look at how our furry friends evolved into the various breeds we know and love.
Published Blood-brain barrier governs ant behavior by altering hormone levels
(via sciencedaily.com) Original source In many animals, including ants, the blood-brain barrier (BBB) ensures normal brain function by controlling the movement of various substances in and out of the brain. Now, researchers have made the unexpected discovery that the BBB in carpenter ants plays an active role in controlling behavior that's essential to the function of entire ant colonies. The key is production in the BBB of a particular hormone-degrading enzyme.
Published Engineers design more powerful RNA vaccines
(via sciencedaily.com) By adding synergistic self-adjuvanting properties to COVID-19 RNA vaccines, researchers showed they could significantly boost the immune response generated in mice.
Published Genetic tools probe microbial dark matter
(via sciencedaily.com) Original source Genetic manipulation of a puzzling, miniscule bacteria that has lived in human mouths at least since the Middle Stone Age is elucidating the genes needed for its unusual lifestyle. These Patescibacteria in the human oral microbiome reside on the surface of another, larger host microbe. Found in many water and land environments, Patescibacteria in general lack the genes required to make many molecules necessary for life, such as the amino acids that make up proteins, the fatty acids that form membranes, and the nucleotides in DNA. This has led researchers to speculate that many of them rely on other bacteria to grow. In a new study, researchers present the first glimpse into the molecular mechanisms behind their relationship with their host cells. They also share details gleaned from fluorescent, time-lapse microsopic imaging of these bacteria as they bud and send out swarms of tiny progeny, only a fraction of which are able to establish a host relationship.
Published Cattle on low-protein rations may need amino acid supplement to boost milk yield
(via sciencedaily.com) Original source When dairy cows are fed diets with reduced protein concentrations -- aimed at decreased environmental nitrogen pollution from their manure such as nitrate leaching, nutrient-laden run-off and ammonia volatilization -- their milk production can suffer. Supplementing the amino acid histidine may help in maintaining, and even increasing, milk and milk-protein yields.
Published New compound unleashes the immune system on metastases
(via sciencedaily.com) Original source A new nanocomplex renders a tumor harmless -- and, on top of that, it trains the immune system to detect and eliminate metastases.
