Published Brightest gamma-ray burst of all time came from the collapse of a massive star
(via sciencedaily.com) Original source In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The team also looked for signatures of heavy elements like gold and platinum in the supernova. They found no evidence of such elements, deepening the mystery of their origins.
Published PFAS exposure from high seafood diets may be underestimated
(via sciencedaily.com) Original source A study suggests that people with diets high in seafood may face a greater risk of exposure to PFAS -- the family of human-made toxins known as 'forever chemicals' -- than previously thought. The researchers stress the need for more stringent public health guidelines that establish how much seafood people can safely consume to limit their exposure, particularly in coastal areas where seafood is frequently eaten.
Published Rock permeability, microquakes link may be a boon for geothermal energy
(via sciencedaily.com) Original source Using machine learning, researchers have tied low-magnitude microearthquakes to the permeability of subsurface rocks beneath the Earth, a discovery that could have implications for improving geothermal energy transfer.
Published Nanoscale movies shed light on one barrier to a clean energy future
(via sciencedaily.com) Original source New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.
Published Tropical coral-infecting parasites discovered in cold marine ecosystems
(via sciencedaily.com) Original source Parasites thought only to infect tropical coral reefs have been discovered in a large variety of creatures in cold marine ecosystems along the Northeast Pacific, according to new research.
Published Method to extract useful proteins from beer-brewing leftovers
(via sciencedaily.com) Original source Researchers have created a method that extracts over 80 percent of the available protein in grain leftovers from brewing beer, commonly known as brewers' spent grain.
Published Oxidant pollutant ozone removes mating barriers between fly species
(via sciencedaily.com) Original source Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.
Published Ocean currents threaten to collapse Antarctic ice shelves
(via sciencedaily.com) Original source Meandering ocean currents play an important role in the melting of Antarctic ice shelves, threatening a significant rise in sea levels.
Published Cloud engineering could be more effective 'painkiller' for global warming than previously thought
(via sciencedaily.com) Original source Cloud 'engineering' could be more effective for climate cooling than previously thought, because of the increased cloud cover produced, new research shows.
Published Hybrid intelligence can reconcile biodiversity and agriculture
(via sciencedaily.com) Original source So far, biodiversity and agricultural productivity could not be reconciled because the socio-ecological system of agriculture is highly complex, and the interactions between humans and the environment are difficult to capture using conventional methods. A research team now shows a promising way to achieve both goals at the same time. They focus on further developing artificial intelligence in combination with collective human judgement: hybrid intelligence.
Published Mapped: 33 new big game migrations across American West
(via sciencedaily.com) Original source A new set of maps that document the movements of ungulates was published today in the fourth volume of the Ungulate Migrations of the Western United States. The maps in this collaborative report series reveal the migration routes and critical ranges used by ungulates, or hooved mammals, in the western U.S., furthering scientists' understanding of the geography of big game migrations.
Published Chemicals stored in home garages linked to ALS risk
(via sciencedaily.com) Original source Storing chemicals in a garage at home may associate with an increased risk of ALS, a study finds. This comes as research has found that exposure to environmental toxins, such as pesticides and volatile organic compounds, are also linked to ALS development. Researchers call the buildup of exposures of the lifetime the ALS exposome.
Published Ants in Colorado are on the move due to climate change
(via sciencedaily.com) Original source Ant species living in Boulder's foothills have shifted their habitat over the last six decades, potentially affecting local ecosystems, suggests a new study.
Published More than half a million global stroke deaths may be tied to climate change
(via sciencedaily.com) Original source A changing climate may be linked to growing death and disability from stroke in regions around the world, according to a new study. Researchers found over three decades that non-optimal temperatures, those above or below temperatures associated with the lowest death rates, were increasingly linked to death and disability due to stroke. The study does not prove that climate change causes stroke. It only shows an association. The study also did not examine other risk factors such as high blood pressure and high cholesterol levels.
Published Using CO2 and biomass, researchers find path to more environmentally friendly recyclable plastics
(via sciencedaily.com) Original source Researchers have created a potential alternative to traditional petroleum-based plastic that is made from carbon dioxide (CO2) and lignin, a component of wood that is a low-cost byproduct of paper manufacturing and biofuel production.
Published New report 'braids' Indigenous and Western knowledge for forest adaptation strategies against climate change
(via sciencedaily.com) Original source Forests could also be potential bulwarks against climate change. But, increasingly severe droughts and wildfires, invasive species, and large insect outbreaks -- all intensified by climate change -- are straining many national forests and surrounding lands in the United States. A report outlines a new approach to forest stewardship that 'braids together' Indigenous knowledge and Western science to conserve and restore more resilient forestlands.
Published Novel UV broadband spectrometer revolutionizes air pollutant analysis
(via sciencedaily.com) Original source A research team has developed a broadband UV dual-comb spectrometer with which air pollutants can be continually measured and their reaction with the environment can be observed in real time.
Published Microplastic 'hotspots' identified in Long Island Sound
(via sciencedaily.com) Original source Forensic and environmental experts have teamed up to develop a new scientific method to pinpoint microplastic pollution 'hotspots' in open waters.
Published Deforestation harms biodiversity of the Amazon's perfume-loving orchid bees
(via sciencedaily.com) Original source A survey of orchid bees in the Brazilian Amazon, carried out in the 1990s, is shedding new light the impact of deforestation on the scent-collecting pollinators, which some view as bellwethers of biodiversity in the neotropics.
Published Cold-affinity algae species are gradually being replaced by warm-affinity ones off the coast of Biscay
(via sciencedaily.com) Original source A study has analyzed the impact of the rise in sea surface temperature on macroalgae communities over the last four decades. Points at various depths were investigated in a location off the coast of Biscay, and an increasing scarcity was observed in the number of cold-affinity structuring species, while small warm-affinity ones have proliferated. The researchers are warning that some ecological functions are in jeopardy as a result.
