Published Scientists 'read' the messages in chemical clues left by coral reef inhabitants
(via sciencedaily.com) Original source What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. But in underwater environments, invisible compounds create a complex 'soup' that is hard for scientists to decipher. Now, researchers have demonstrated a way to extract and identify these indicator compounds in seawater. They found metabolites previously undetected on reefs, including three that may represent different reef organisms.
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 A new study reveals that marine cyanobacteria communicate
(via sciencedaily.com) Original source A breakthrough study changes the way we understand cyanobacteria, which are essential for the sustenance of life. The study shows that these organisms do not operate in isolation, but rather physically interact through membrane-nanotubes, which function as exchange bridges between cells.
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 Tropical forests adjust strategies to thrive even when soils are nutrient poor
(via sciencedaily.com) Original source Tropical forests store a third of the world's carbon in their wood and soils. However, their future as a carbon sink has been uncertain. Scientists have long wondered whether nutrient-poor tropical soils would limit the ability of mature and recovering forests to thrive. A study offers a hopeful response, suggesting that forests have flexible strategies that help them overcome the challenge of scarce nutrients.
Published Fish in schools have an easier time swimming in rough waters
(via sciencedaily.com) Original source Swimming through turbulent water is easier for schooling fish compared to solitary swimmers, according to a new study.
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 Fighting fires from space in record time: How AI could prevent devastating wildfires
(via sciencedaily.com) Original source Scientists are getting closer to detecting bushfires in record time, thanks to cube satellites with onboard AI now able to detect fires from space 500 times faster than traditional on-ground processing of imagery.
Published Fishy mystery of marine reptile solved
(via sciencedaily.com) Original source The identity of a prehistoric marine reptile has finally been revealed after experts discovered that some of its remains actually belonged to fish.
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 'Open gates' in warming Arctic are expanding salmon range
(via sciencedaily.com) Original source New research has connected warming ocean temperatures to higher Pacific salmon abundance in the Canadian Arctic, an indicator that climate change is creating new corridors for the fish to expand their range. Salmon haven't historically been seen in large numbers in the Arctic Ocean and its watersheds, but in recent years incidental catches by subsistence fishermen have occasionally surged. Researchers working together with communities in the western Canadian Arctic, connected those salmon booms with a sequence of warm, ice-free conditions in the Arctic Ocean north of Alaska.
Published Early summer fishing can have an evolutionary impact, resulting in smaller salmon
(via sciencedaily.com) Original source A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon. This information can help to conserve large fish essential for the diversity and viability of salmon populations.
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 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 'Missing' early sea sponges discovered
(via sciencedaily.com) Original source Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for years.
Published A novel approach to tracking conservation reveals more areas may be conserved than currently accounted for
(via sciencedaily.com) Original source An international team of conservation researchers and practitioners has developed an inclusive inventory approach for tracking global conservation areas, with an emphasis on local data and expertise. Applying this approach across the nine countries spanning the Amazon Rainforest identified a wide array of conservation areas with greater diversity and area coverage than existing tracking systems showed.
Published Rate of global warming caused by humans at an all-time high, say scientists
(via sciencedaily.com) Original source Global warming caused by humans is advancing at 0.26 C per decade -- the highest rate since records began, according to new research by over 50 leading international scientists.
Published Giant viruses found on Greenland ice sheet
(via sciencedaily.com) Original source Giant viruses found on the Greenland ice sheet probably regulate the growth of snow algae on the ice by infecting them. Knowing how to control these viruses could help us reduce the rate of ice-melt.
