Published Smell reports reveal the need to expand urban air quality monitoring, say researchers



Researchers have uncovered surprising insights into the Vancouver region's 'smellscape' using data from the Smell Vancouver app. Analyzing 549 reports from one year of app data, they discovered that 'rotten' and 'chemical' odours dominated, making up about 65 per cent of submissions. These unpleasant smells were linked to self-reported health issues like headaches and anxiety, leading some residents to change their behaviours, like closing windows even in stifling-hot weather.
Published Scientists devise method to secure Earth's biodiversity on the moon



New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.
Published Climate change means that tropical cyclones in Southeast Asia are developing faster, lasting longer



A study reveals that tropical cyclones in Southeast Asia are now forming closer to coastlines, intensifying more rapidly, and lingering longer over land.
Published Strong El Nino makes European winters easier to forecast



Forecasting European winter weather patterns months in advance is made simpler during years of strong El Ni o or La Ni a events in the tropical Pacific Ocean, a new study has found.
Published Recent volcanic 'fires' in Iceland triggered by storage and melting in crust



Scientists have detected geochemical signatures of magma pooling and melting beneath the subsurface during the 'Fagradalsfjall Fires', that began on Iceland's Reykjanes peninsula in 2021. Samples show that the start of the eruption began with massive pooling of magma, contrasting initial hypothesis for magma ascent straight from the mantle.
Published Bright prospects for engineering quantum light



Computers benefit greatly from being connected to the internet, so we might ask: What good is a quantum computer without a quantum internet?
Published Researchers develop general framework for designing quantum sensors



Researchers have designed a protocol for harnessing the power of quantum sensors. The protocol could give sensor designers the ability to fine-tune quantum systems to sense signals of interest, creating sensors that are vastly more sensitive than traditional sensors.
Published NASA data shows July 22, 2024 was Earth's hottest day on record



July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023. These record-breaking temperatures are part of a long-term warming trend driven by human activities, primarily the emission of greenhouse gases.
Published A blue miracle: How sapphires formed in volcanoes



Sapphires are among the most precious gems, yet they consist solely of chemically 'contaminated' aluminum oxide, or corundum. It is widely assumed that these crystals with their characteristically blue color come from deep crustal rocks and accidentally ended up on the Earth's surface as magma ascended. Geoscientists have now been able to show that the sapphire grains found in the Eifel (Germany) formed in association with volcanism.
Published Robotics: Self-powered 'bugs' can skim across water to detect environmental data



Researchers have developed a self-powered 'bug' that can skim across the water, and they hope it will revolutionize aquatic robotics.
Published California a botanical and climate change hot spot



Climate-driven shifts in California's biodiversity call for innovation and continued environmental stewardfship, says a new study. California's 30x30 Initiative and efforts to harmonize biodiversity with renewable energy are promising steps, while wildfire strategies need to further adapt.
Published Local food production saves costs and carbon



Emphasizing local food production over imported substitutes can lead to significant cost and carbon savings, according to data from the Inuvialuit Settlement Region in the Canadian Arctic. The research shows potential annual savings of more than 3.1 million Canadian dollars and roughly half the carbon emissions when locally harvested food is used instead of imported food. The study underscores the importance of climate change policies that take local food systems into account. Weakening of these local systems could lead to increased emissions and jeopardize the health and food security of remote communities.
Published Countries need to co-operate on migration as climate crisis worsens



Humanity must rethink migration as the climate crisis drives rapid global changes, researchers say.
Published Optical fibers fit for the age of quantum computing



A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing.
Published AI method radically speeds predictions of materials' thermal properties



Researchers developed a machine-learning framework that can predict a key property of heat dispersion in materials that is up to 1,000 times faster than other AI methods, and could enable scientists to improve the efficiency of power generation systems and microelectronics.
Published New study disputes Hunga Tonga volcano's role in 2023-24 global warm-up



New research is exploring the climate impact of the 2022 Hunga Tonga volcano eruption and challenging existing assumptions about its effects in the process.
Published Thousands of birds and fish threatened by mining for clean energy transition, study finds



Our increasing demand for metals and minerals is putting over four thousand vertebrate species at risk, with the raw materials needed for clean energy infrastructure often located in global biodiversity hotspots, a study has found.
Published Generative AI pioneers the future of child language learning



Researchers create a storybook generation system for personalized vocabulary learning.
Published Researchers develop state-of-the-art device to make artificial intelligence more energy efficient



Engineering researchers have demonstrated a state-of-the-art hardware device that could reduce energy consumption for artificial intelligent (AI) computing applications by a factor of at least 1,000.
Published Folded peptides are more electrically conductive than unfolded peptides



What puts the electronic pep in peptides? A folded structure, according to a new study. Researchers combined single-molecule experiments, molecular dynamics simulations and quantum mechanics to validate the findings.
