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 This fish doesn't just see with its eyes -- it also sees with its skin
(via sciencedaily.com) Original source Without a mirror, it can be hard to tell if you're blushing, or have spinach in your teeth. But one color-changing fish has evolved a clever way to keep watch on the parts of itself that lie outside its field of view -- by sensing light with its skin.
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 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 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 The modern sea spider had started to diversify by the Jurassic, study finds
(via sciencedaily.com) Original source An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind.
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.
Published Race-based variations in gut bacteria emerge by 3 months of age
(via sciencedaily.com) Original source Early social and environmental exposures can have large and lasting effects on child development and adult health. One of the systems that is vulnerable to external influence is the gut microbiome. A new study highlights a critical development window during which racial differences in the gut microbiome emerge. The findings are based on analysis of data from 2,756 gut microbiome samples from 729 U.S. children between birth and 12 years of age.
Published New insights into fighting antimicrobial resistance
(via sciencedaily.com) Original source Cooking food thoroughly and avoiding some types of vegetables and salad during a course of antibiotic treatment could potentially reduce antibiotic resistance, by preventing bacteria carrying resistance genes getting into the gut, according to a new study.
Published Molecules in vegetables can help to ease lung infection
(via sciencedaily.com) Original source Researchers have found that molecules in vegetables like broccoli or cauliflower help to maintain a healthy barrier in the lung and ease infection.
Published Treating back-to-school ear infections without antibiotic resistance
(via sciencedaily.com) Original source 'Back-to-school' season means buying pens, figuring out the bus route, and ... earaches. Cutting corners with antibiotics, however, can accelerate resistance. Today, researchers report developing a single-use nanoscale system that's unlikely to generate resistance. Using a compound similar to bleach in test animals, they show it can kill off a bacterium that causes ear infections, and it could someday be easily applied as a gel.
Published Microgreens and mature veggies differ in nutrients, but both might limit weight gain
(via sciencedaily.com) Original source Young vegetables known as microgreens are reputed to be particularly good for health. But are microgreens the superfood they're claimed to be, and how do they compare to mature veggies? Scientists have found that their nutritional profiles differ, as do their effects on gut bacteria. Yet, tests in mice suggest that both microgreen and mature vegetables can limit weight gain.
Published Sea sequin 'bling' links Indonesian islands' ancient communities
(via sciencedaily.com) Original source Microscopic analysis has revealed that trends in body ornamentation were shared across Indonesian islands.
Published World's deepest coral calcification rates measured off Hawaiian Islands
(via sciencedaily.com) In the waters off the Hawaiian Islands, rates of calcification were measured in the deepest coral colonies.
Published Teeth could preserve antibodies hundreds of years old, study finds
(via sciencedaily.com) Original source Teeth could be capable of preserving antibodies for hundreds of years, allowing scientists to investigate the history of infectious human diseases, a new study has found.
Published Building muscle in the lab
(via sciencedaily.com) Original source A new method allows large quantities of muscle stem cells to be safely obtained in cell culture. This provides a potential for treating patients with muscle diseases -- and for those who would like to eat meat, but don't want to kill animals.
Published Common wristbands 'hotbed' for harmful bacteria including E. coli, staphylococcus
(via sciencedaily.com) Original source Routinely cleaning wristbands is generally ignored. New research finds 95 percent of wristbands tested were contaminated. Rubber and plastic wristbands had higher bacterial counts, while gold and silver, had little to no bacteria. Bacteria found were common skin residents of the genera Staphylococcus and Pseudomonas, and intestinal organisms of the genera Escherichia, specifically E. coli. Staphylococcus was prevalent on 85 percent of the wristbands; researchers found Pseudomonas on 30 percent of the wristbands; and they found E. coli bacteria on 60 percent of the wristbands, which most commonly begins infection through fecal-oral transmission.
Published Protective particles allow engineered probiotics to report gut disease
(via sciencedaily.com) Original source Bioengineers developed a platform that enhances survival and function of probiotics engineered to diagnose inflammatory bowel disease in animals. The technology holds promise for minimally invasive disease monitoring and advanced smart therapeutics.
