Bumblebees" nutrition influences their pesticide resistance
How susceptible bumblebees are to a common fungicide depends on the flowering plants to which it is applied on and how diverse the food supply is that is available to the insects. Monocultures can increase the insects' sensitivity to the fungicide or.....»»
Flood risk mapping is a public good, so why the public resistance in Canada?
Flood risk maps are an essential public good. Indeed, many countries like the United Kingdom already offer flood risk mapping......»»
Blighia sapida: A tropical fruit with antimicrobial properties
Antimicrobial resistance (AMR) remains 1 of the top 3 global public health challenges facing humanity. Every year, 70,000 people die globally from AMR, and the threat is exacerbated by the fact that we have moved from the era of excess antibiotics to.....»»
What makes an orange? New study finds one gene, seven chemicals
Tracing an orange's flavor could help us get both disease resistance and taste. Enlarge (credit: Tanja Ivanova) In the US, for orange juice to be labeled as such, it must be 90 percent sweet orange, or Citrus sinensis. T.....»»
What makes a pathogen antibiotic-resistant?
Antimicrobial resistance is a story of constantly moving parts and players. With every new or tweaked antibiotic or antimicrobial drug, the targeted pathogens begin the evolutionary dance of acquiring resistance, prompting researchers to constantly d.....»»
Not just humans: Bees and chimps can also pass on their skills
Bumblebees and chimpanzees can learn skills from their peers so complicated that they could never have mastered them on their own, an ability previously thought to be unique to humans, two studies said on Wednesday......»»
Researchers focus on finding flaws in superbugs" armor
Recent years have seen the rise of bacterial pathogens that have developed resistance to antibiotics. One such superbug, carbapenem-resistant Acinetobacter baumannii (CRAB), kills hundreds of critically ill patients in the U.S. each year, usually in.....»»
Emerging Salmonella variety in dairy cows found to worsen antimicrobial resistance
A study of more than 5,000 Salmonella bacteria isolated over 15 years from dairy cattle samples in the Northeast reveals a significant increase in resistance to the antimicrobial medications ampicillin, florfenicol and ceftiofur......»»
Supporting disease-challenged broiler chickens through nutrition
When broiler chickens are busy fighting the parasitic infection coccidiosis, they can't absorb nutrients efficiently or put energy toward growth. With consumer sentiment pitted against antimicrobials and other drugs, producers still have some options.....»»
Degree of cell crowding in the early human embryo influences cell identity decision, new culture system finds
Research conducted by Dr. Shota Nakanoh in a collaboration between Dr. Teresa Rayon's lab at the Institute and Professor Ludovic Vallier's lab at the Wellcome-MRC Cambridge Stem Cell Institute has determined that the degree of cell crowding in the ea.....»»
Team finds novel vehicle for antibiotic resistance
Antibiotic resistance is a significant and growing medical problem worldwide. Researchers at the Marine Biological Laboratory (MBL) and collaborators have found a novel genetic arrangement that may help a common bacterium in the human gut, Bacteroide.....»»
How "the strong force" influences the gravitational wave background
Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe......»»
Scientists discover 18 new species of gut microbes in search for origins of antibiotic resistance
In a paper published February 28 in Proceedings of the National Academy of Sciences (PNAS), a research team describes the discovery of 18 never-before-seen species of bacteria of the Enterococcus type that contain hundreds of new genes—findings tha.....»»
Unlocking the secrets of geraniol: A key to enhanced disease resistance in tea plants
Geraniol contributes to the floral scent of tea (Camellia sinensis) and is abundant in tea plants, yet its biosynthesis and role in stress responses remain unclear......»»
Scientists discover why ripe fruit is more susceptible to necrotrophic pathogens than unripe fruit
In a recent study published in Molecular Plant, researchers have elucidated the mechanism underlying the increased susceptibility to necrotrophs during fruit ripening and have developed a rapid strategy to improve tomato fruit resistance to necrotrop.....»»
Research confirms exogenous methyl jasmonate can enhance tomato resistance
Tomato (Solanum lycopersicum L.) is the most widely cultivated and consumed horticultural crop. At present, saline-alkali is an important abiotic stress source that affects tomato production. Exogenous methyl jasmonate (MeJA) can enhance the resistan.....»»
Unlocking the potential of protease inhibitors for enhanced pest resistance in tea plants
Protease inhibitors are a promising strategy for enhancing herbivore resistance in plants, which is crucial for addressing the significant yield losses in crops such as tea plants due to insect herbivores. Serine protease inhibitors (SERPIN) are one.....»»
The effects of primer pairs, PCR conditions, and peptide nucleic acid clamps on plant root fungal diversity assessment
Fungi are frequently found both around and within plant tissues (especially in roots) and are involved in both plant nutrient acquisition and resistance to pathogens. Thus, characterizing the diversity and composition of plant-associated fungal commu.....»»
Scientists develop rapid gene-screening platform to boost disease resistance in crops
Scientists at CSIRO, Australia's national science agency, have achieved a breakthrough in molecular plant pathology, marking a technological leap forward for breeding durable disease-resistant crops......»»
What ancient farmers can really teach us about adapting to climate change—and how political power influences outcomes
In dozens of archaeological discoveries around the world, from the once-successful reservoirs and canals of Angkor Wat in Cambodia to the deserted Viking colonies of Greenland, new evidence paints pictures of civilizations struggling with unforeseen.....»»
Generative AI can accelerate study time, research shows
Time plays a crucial role in higher education learning and influences learning progress and the achievement of academic goals. Shortening learning time through AI-supported, personalized approaches can help to reduce drop-out rates and increase enrol.....»»
