Published Chitin from consuming insects can help both gut microbiota and global health
(via sciencedaily.com) Original source Increased insect consumption by humans may be better for both gut health and planetary health. Chitin (kai'tin) and healthy fats from insects appear to contribute to healthy gut microbiota and are strong sources of protein and nutrients, according to a recent paper.
Published Hungry eyes: Spiders lose vision when they're starving
(via sciencedaily.com) Original source Biologists have discovered that underfed jumping spiders lose light-sensitive cells that are key to their vision.
Published Water arsenic including in public water is linked to higher urinary arsenic totals among the U.S. population
(via sciencedaily.com) Original source A new study shows that water arsenic levels are linked to higher urinary arsenic among the U.S. population for users of both private wells and public water systems.
Published Research collaboration aims to improve nationwide water quality, restore wetlands
(via sciencedaily.com) Original source The new classification system demonstrates the effects wetlands have on water quality at a continental scale -- invaluable data that can be used to better define whether wetlands are federally regulated under the U.S. Clean Water Act.
Published Chicken breeding in Japan dates back to fourth century BCE
(via sciencedaily.com) Original source Conclusive evidence of chicken breeding in the Yayoi period of Japan has been discovered from the Karako-Kagi site.
Published A once-stable glacier in Greenland is now rapidly disappearing
(via sciencedaily.com) Original source As climate change causes ocean temperatures to rise, one of Greenland's previously most stable glaciers is now retreating at an unprecedented rate, according to a new study.
Published Nature's chefs: Scientists propose food-making as means of understanding species interactions
(via sciencedaily.com) Original source An interdisciplinary group of researchers is proposing a new way to think of some interactions between species, classifying a variety of plants, animals and fungi as 'nature's chefs.' Specifically, nature's chefs are organisms that provide food -- or the illusion of food -- to other organisms. The concept offers a new perspective on species interactions, which can inform how people think about food across the tree of life as well as disparate research disciplines.
Published Why this bird flu is different: Scientists say new avian influenza requires urgent coordinated response
(via sciencedaily.com) Original source A new study tracks arrival and spread of highly pathogenic Avian Influenza (H5N1) decimating wild birds, impacting poultry and pushing up egg prices. The team found that the deadly impact on wild birds and a shift from seasonal to year-round infections signal dangerous changes in avian influenza in the U.S.
Published X-ray analysis sheds new light on prehistoric predator's last meal
(via sciencedaily.com) Original source We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.
Published Swimming secrets of prehistoric reptiles unlocked by new study
(via sciencedaily.com) Original source The diverse swimming techniques of the ancient reptiles that ruled the Mesozoic seas have been revealed.
Published Bird feeding helps small birds fight infection
(via sciencedaily.com) Original source Seeds and fat balls do more than just fill small birds' stomachs. New research from Lund University in Sweden shows that feeding during the wintertime causes birds to be healthier, since they do not have to expend as much energy fighting infections.
Published Researchers develop carbon-negative concrete
(via sciencedaily.com) Original source A viable formula for a carbon-negative, environmentally friendly concrete that is nearly as strong as regular concrete has been developed. In a proof-of-concept work, the researchers infused regular cement with environmentally friendly biochar, a type of charcoal made from organic waste, that had been strengthened beforehand with concrete wastewater. The biochar was able to suck up to 23% of its weight in carbon dioxide from the air while still reaching a strength comparable to ordinary cement. The research could significantly reduce carbon emissions of the concrete industry, which is one of the most energy- and carbon-intensive of all manufacturing industries.
Published Counting the cost of sunshine: Finding a better metric to measure human ecological footprints
(via sciencedaily.com) Original source The human food-energy-water system is wickedly interconnected, but most of the links in the network are neither global nor local -- the action lies in everyday trade between counties and states that rely on each other's ecosystems. To capture a better picture of human impacts in this system, you need a measurement that starts at the source -- the sun.
Published Filtering pollution: A microfluidic device for collecting microplastics via acoustic focusing
(via sciencedaily.com) Original source Microplastics (MPs), plastic debris smaller than 5 mm, indirectly harm the environment. They are traditionally collected and removed from water by filtering through meshes, which is inefficient. Researchers have now developed a high-enrichment microfluidic device that utilizes acoustic focusing to collect and remove 10--200 ?m MPs from wastewater without recirculation. Its collection rates and enrichment ratios ranged approximately from 70--90% and 50--100, respectively on test samples.
Published A solar hydrogen system that co-generates heat and oxygen
(via sciencedaily.com) Original source Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size.
Published Temperature, drought influencing movement of Plains bison
(via sciencedaily.com) Original source Temperature and severe drought can drive movement among herds of Plains bison, says a recent study. The team's GPS-backed data suggests that conserving the once-endangered species could depend on accounting for the climate extremes that Plains bison will likely encounter moving forward.
Published Recovering rare earth elements in environmental water
(via sciencedaily.com) Original source A research group has succeeded in selectively recovering trace rare earth elements in synthetic seawater and environmental water, such as hot spring water, using baker's yeast with a phosphate group added. The phosphorylated yeast is expected to be utilized as a material for recovering useful metals and removing toxic metals, thereby contributing to the realization of a metal resource-circulating society.
Published Software to untangle genetic factors linked to shared characteristics among different species
(via sciencedaily.com) Original source Scientists have developed a software package to help answer key questions about genetic factors associated with shared characteristics among different species.
Published Scientists develop new way to measure wind
(via sciencedaily.com) Original source Atmospheric scientists have developed an algorithm that uses data from water vapor movements to measure wind. This could help predict extreme events like hurricanes.
Published Nature-based management is making rivers more resilient
(via sciencedaily.com) Original source Nature-based management is making rivers more resilient. New research shows progress in Australia towards United Nations goals, making rivers more able to recover from flood, drought and other impacts. In July 2022, the 120-kilometre Wollombi Brook, which flows north into the Hunter Valley in New South Wales, suffered one of its biggest floods on record. And it held up remarkably well, says Professor Kirstie Fryirs of the School of Natural Sciences at Macquarie University. 'Yes, there was widespread inundation, but the flood waters were slower and the vegetation prevented large scale erosion and sediment movement. 'All the hard work that a very active community put into nature-based rehabilitation for more than 20 years, such as continuous streamside revegetation, played a role in this outcome.' It is one of the best examples in Australia of sustainable environmental restoration in the management of rivers, she says
