Published Case study: Drug-resistant bacteria responds to phage-antibiotic combo therapy
(via sciencedaily.com) Original source An experimental treatment using viruses to kill bacteria gave a mother more months of life and furthered knowledge to help future patients, researchers report in a recent case study.
Published By growing animal cells in rice grains, scientists dish up hybrid food
(via sciencedaily.com) Original source From lab-grown chicken to cricket-derived protein, these innovative alternatives offer hope for a planet struggling with the environmental and ethical impacts of industrial agriculture. Now, scientists add a new recipe to the list -- cultured beef rice -- by growing animal muscle and fat cells inside rice grains. The method results in a nutritious and flavorful hybrid food that, once commercialized, could offer a more affordable protein alternative with a smaller carbon footprint.
Published Biomanufacturing using chemically synthesized sugars enables sustainable supply of sugar without competing with food
(via sciencedaily.com) Original source Researchers have succeeded in biomanufacturing from chemically synthesized sugar for the first time in the world. With refinement of this technology, one can envision a future society in which the sugar required for biomanufacturing can be obtained 'anytime, anywhere, and at high rate'. In the future, biomanufacturing using chemically synthesized sugar is expected to be a game changer in the biotechnology field -- including the production of biochemicals, biofuels, and food, where sugar is an essential raw material -- ultimately leading to the creation of a new bio-industry.
Published CRISPR-copies: New tool accelerates and optimizes genome editing
(via sciencedaily.com) Original source Researchers are further improving CRISPR's versatility to engineer new grasses and yeasts for biochemical production.
Published Low-cost microbe can speed biological discovery
(via sciencedaily.com) Original source Researchers have created a new version of a microbe to compete economically with E. coli -- a bacteria commonly used as a research tool due to its ability to synthesize proteins -- to conduct low-cost and scalable synthetic biological experiments.
Published New trial highlights incremental progress towards a cure for HIV-1
(via sciencedaily.com) Original source A new clinical trial suggests that a combination of the drug vorinostat and immunotherapy can coax HIV-infected cells out of latency and attack them. The findings highlight how close -- yet still far -- researchers have come to developing a cure for HIV-1.
Published Interactions between flu subtypes predict epidemic severity more than virus evolution
(via sciencedaily.com) Original source Researchers have shed new light on how viral evolution, population immunity, and the co-circulation of other flu viruses shape seasonal flu epidemics.
Published Better diagnosis and treatment of cryptococcosis
(via sciencedaily.com) Original source A global guideline for the management of cryptococcosis, a fungal infection that can have serious health consequences, has been developed.
Published Compounds released by bleaching reefs promote bacteria, potentially stressing coral further
(via sciencedaily.com) Original source New research revealed that when coral bleaching occurs, corals release unique organic compounds into the surrounding water that not only promote bacterial growth overall, but select for opportunistic bacteria that may further stress reefs.
Published Archaeologists discover oldest known bead in the Americas
(via sciencedaily.com) Original source The bead found at the La Prele Mammoth site in Wyoming's Converse County is about 12,940 years old and made of bone from a hare.
Published Researchers uncover a key link in legume plant-bacteria symbiosis
(via sciencedaily.com) Original source Researchers have unveiled a groundbreaking discovery shedding light on the intricate play between legume plants and nitrogen-fixing bacteria. Their study details the crucial role played by phosphorylation in driving the formation of symbiotic organs, known as nodules, on plant roots. The long-term goal is to enable symbiosis in root nodules in important crops such as barley, maize and rice to avoid the use of chemical fertilizers.
Published 3D ice printing can create artificial blood vessels in engineered tissue
(via sciencedaily.com) Original source A new 3D printing method uses ice to build a template for artificial blood vessels in engineered tissue. Researchers hope the vessels could eventually be used in artificial organ transplants or drug testing.
Published The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly
(via sciencedaily.com) Original source Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.
Published Understanding chronic wasting disease in deer
(via sciencedaily.com) Original source A new collaborative study analyzed fecal samples to shed light on how the fatal disease impacts the gut microbiome in deer, providing a promising tool for disease surveillance.
Published Researchers uncover genetic factors for severe Lassa fever
(via sciencedaily.com) Original source Researchers report the results of the first ever genome-wide association study (GWAS) of a biosafety level 4 (BSL-4) virus. The team found two key human genetic factors that could help explain why some people develop severe Lassa fever, and a set of LARGE1 variants linked to a reduced chance of getting Lassa fever. The work could lay the foundation for better treatments for Lassa fever and other similar diseases. The scientists are already working on a similar genetics study of Ebola susceptibility.
Published Scientists develop artificial 'worm gut' to break down plastics
(via sciencedaily.com) Original source A team of scientists has developed an artificial 'worm gut' to break down plastics, offering hope for a nature-inspired method to tackle the global plastic pollution problem.
Published Surprise discovery of tiny insect-killing worm
(via sciencedaily.com) Original source Scientists have discovered a tiny worm species that infects and kills insects. These worms, called nematodes, could control crop pests in warm, humid places where other beneficial nematodes are currently unable to thrive.
Published Friend or foe? Ancient partnership between moss and fungi
(via sciencedaily.com) Original source Researchers have shed new light on the ancient relationship between moss and fungi. They discovered that intricate moss-fungi interactions often depended on a third variable -- the presence of endobacteria within the fungi themselves.
Published Organic compound found in trees could prevent contact lens eye infections
(via sciencedaily.com) Original source Researchers say hydroquinine could be an effective naturally occurring disinfecting solution for contact lenses and help combat keratitis infections.
Published New approach for fast and cost-effective pathogen detection
(via sciencedaily.com) Original source The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team now develops intelligent, miniaturized biosensor devices and systems using nanomaterials to determine biomolecules and cells as well as biochemical reactions or processes as disease markers. The team's current publication describes the development of a portable, palm-sized test system that can simultaneously carry out up to thirty-two analyses of one sample.
