Published Mushroom stump waste could be inexpensive, healthy chicken feed supplement
(via sciencedaily.com) Original source Feed costs for producing broiler chickens accounts for 60% to 70% of total production costs, and stump waste from the production of button mushrooms comprises nearly 30% of total mushroom weight. Marrying the two has the potential to reduce both cost and waste, especially in Pennsylvania, which is a national leader in the production of broiler chickens and button mushrooms.
Published Frozen? Let it melt with efficient new de-icer friendly to the environment
(via sciencedaily.com) Original source A research team has found a de-icing mixture with high effectiveness and low environmental impact after using machine learning to analyze ice melting mechanisms of aqueous solutions of 21 salts and 16 organic solvents.
Published Earth and space share the same turbulence
(via sciencedaily.com) Original source Researchers have discovered that the turbulence found in the thermosphere -- known as the gateway to space -- and turbulence in the troposphere, here closer to sea level, follow the same physical laws despite having drastically different atmospheric compositions and dynamics.
Published Silkworms help grow better organ-like tissues in labs
(via sciencedaily.com) Original source Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used in a kidney organ-on-a-chip platform, the membrane helped tissues grow to recreate the functionality of both healthy and diseased kidneys.
Published Diagnosing damaged infrastructure from space
(via sciencedaily.com) Original source Synthetic Aperture Radar (SAR) remote sensing systems allow researchers to inspect and characterize pavements, retaining walls, and embankments from space and can help determine if there are flaws that should be further inspected for repair.
Published Climate crisis puts Australia's ski industry on slippery slope, but not all hope is lost
(via sciencedaily.com) Original source Australia's ski industry is at risk of major disruptions and shorter seasons if the current level of climate pollution continues, according to new modelling. The report found the average ski season across all resorts in Australia will be 44 days shorter by 2050 under a mid-greenhouse gas emissions scenario and 55 days shorter under a high-emissions scenario.
Published Fish out of water: How killifish embryos adapted their development
(via sciencedaily.com) Original source The annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body structure is not predetermined from the outset. This could enable the species to survive dry periods unscathed.
Published Climate policy: competing crises
(via sciencedaily.com) Original source Current crises are distracting from the climate crisis and weakening support for climate action, a Europe-wide survey reveals.
Published Determining sex in ants
(via sciencedaily.com) Original source Researchers have been investigating the molecular mechanisms responsible for determining sex in ants. Although the vast majority of an ant colony consists of female workers, males are essential to the continuing survival of the species. In order to uncover the mechanisms involved, the researchers decided to focus on diploid males, which occasionally occur in the Argentine ant.
Published Marsupials key to discovering the origin of heater organs in mammals
(via sciencedaily.com) Original source Around 100 million years ago, a remarkable evolutionary shift allowed placental mammals to diversify and conquer many cold regions of our planet. New research shows that the typical mammalian heater organ, brown fat, evolved exclusively in modern placental mammals. The research team demonstrated that marsupials, our distant relatives, possess a not fully evolved form of brown fat. They discovered that the pivotal heat-producing protein called UCP1 became active after the divergence of placental and marsupial mammals. This finding is crucial for understanding the role of brown fat in mammalian evolution, endothermy, and metabolism.
Published Scientists question effectiveness of nature-based CO2 removal using the ocean
(via sciencedaily.com) Original source Limited understanding of basic ocean processes is hindering progress in marine carbon dioxide removal, with the on-going commercialization of some approaches 'premature and misguided'. Scientists now review the climatic effectiveness of four 'nature-based' techniques using marine biological processes. These involve shellfish cultivation, seaweed farming, coastal blue carbon -- using the restoration of seagrass, saltmarsh and mangrove forests -- and increasing whale populations through 're-wilding'.
Published Universal bitter blocker could help patients take their medicines as prescribed
(via sciencedaily.com) Original source Strong bitterness is the main reason why people all over the world, especially children, avoid taking their medicines, putting their health, and sometimes, their lives at risk. Now, a group of scientists has identified the first temporary, universal taste blocker that works in people.
Published 'Painting with light' illuminates photo evidence of air pollution
(via sciencedaily.com) Original source Photographs making invisible air pollution visible have sparked discussion around the impact of air pollution on communities ascross the globe.
Published Uptake of tire wear additives by vegetables grown for human consumption
(via sciencedaily.com) Original source Car tires contain hundreds of chemical additives that can leach out of them. This is how they end up in crops and subsequently in the food chain. Researchers have now detected these chemical residues in leafy vegetables for the first time. Although the concentrations were low, the evidence was clear, a finding that is also known for drug residues in plant-based foods.
Published A cracking discovery -- eggshell waste can recover rare earth elements needed for green energy
(via sciencedaily.com) Original source A collaborative team of researchers has made a cracking discovery with the potential to make a significant impact in the sustainable recovery of rare earth elements (REEs), which are in increasing demand for use in green energy technologies. The team found that humble eggshell waste could recover REES from water, offering a new, environmentally friendly method for their extraction.
Published Bone loss drugs can help azoles fight fungal infections
(via sciencedaily.com) Original source A new study suggests that adding common bone loss drugs to azoles can improve efficacy when treating fungal infections.
Published Climate change will make ozone pollution worse: Here's how
(via sciencedaily.com) Original source A new study finds climate change is likely to make upward spikes of ozone at ground level worse by 2050, which could result in many parts of the United States falling out of compliance with air quality standards and increasing risks to public health.
Published Electrified charcoal 'sponge' can soak up CO2 directly from the air
(via sciencedaily.com) Original source Researchers have developed a low-cost, energy-efficient method for making materials that can capture carbon dioxide directly from the air. Researchers used a method similar to charging a battery to instead charge activated charcoal, which is often used in household water filters.
Published New technique reveals how gene transcription is coordinated in cells
(via sciencedaily.com) Original source Researchers invented a technique that allows them to observe which genes and enhancers are active in a cell at the same time. This could help them determine which enhancers control which genes and may reveal potential new drug targets for genetic disorders.
Published Father's diet before conception influences children's health
(via sciencedaily.com) Original source A recent study provides new insights into how fathers' diets and overweight can affect their children's health even before conception. The findings of the study can help develop preventive health measures for men wishing to become fathers: The healthier the father's diet, the lower the risk for their children to develop obesity or diseases such as diabetes later in life.
