Published Wildfire, drought cause $11.2 billion in damage to private timberland in three Pacific states, study finds
(via sciencedaily.com) Original source Wildfires and drought have led to $11.2 billion in damages to privately held timberland in California, Oregon and Washington over the past two decades, a new Oregon State University study found.
Published Aerosols: When scents influence our climate
(via sciencedaily.com) Original source Tiny particles that form from molecules in the air play an important role for climate change. But until now, the have been poorly understood. Scientists have now analyzed how these particles form.
Published Forming ice: There's a fungal protein for that
(via sciencedaily.com) Original source New research explores how proteins produced by a common fungus trigger ice nucleation at warm temperatures. The study holds potential implications for improving our understanding of how life affects precipitation and climate.
Published Solar-powered device produces clean water and clean fuel at the same time
(via sciencedaily.com) Original source A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been developed by researchers.
Published Yucatán's underwater caves host diverse microbial communities
(via sciencedaily.com) Original source With help from an experienced underwater cave-diving team, researchers have constructed the most complete map to date of the microbial communities living in the submerged labyrinths beneath Mexico's Yucatán Peninsula. Researchers found the cave system's microbiome is distinct from the nearby sea, and microbial communities vary between cave systems forming distinct 'neighborhoods.'
Published Low-intensity fires reduce wildfire risk by 60%
(via sciencedaily.com) Original source High-intensity, often catastrophic, wildfires have become increasingly frequent across the Western U.S. Researchers quantified the value of managed low-intensity burning to dramatically reduce the risk of such fires for years at a time.
Published How mega-floods can be predicted
(via sciencedaily.com) Original source Extreme flood events are extraordinary outliers that were not considered possible on the basis of local data. However, if one considers the entire European continent, these local surprises are no longer surprising at all. If data from other regions with similar hydrological conditions is taken into account, the extent of these 'mega-floods' suddenly becomes predictable.
Published Barnacle bends shape to fend off warm-water sea snails on the move
(via sciencedaily.com) Original source Some barnacles are 'morphing' to protect themselves from predatory warm-water sea snails, which are expanding into their territory due to climate change.
Published Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage
(via sciencedaily.com) Original source Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
Published Greenland's glacier retreat rate has doubled over past two decades
(via sciencedaily.com) Original source A new study documents how Greenland's peripheral glaciers have changed from 1890 to 2022. Using satellite images and a unique archive of historical aerial photos, researchers documented changes in the lengths of more than 1,000 of the country's glaciers over the past 130 years. Although glaciers in Greenland have experienced retreat throughout the last century, the rate of their retreat has rapidly accelerated over the last two decades.
Published Zooplankton in ocean and freshwater are rapidly escalating the global environmental threat of plastics
(via sciencedaily.com) Original source A collaborative research team has recently revealed that rotifers, a kind of microscopic zooplankton common in both fresh and ocean water around the world, are able to chew apart microplastics, breaking them down into even smaller, and potentially more dangerous, nanoplastics -- or particles smaller than one micron. Each rotifer can create between 348,000 -- 366,000 per day, leading to uncountable swarms of nanoparticles in our environment.
Published Feral horses and peatland carbon emissions
(via sciencedaily.com) Original source A ground-breaking new study has found carbon emissions from Australian alpine peatlands to be much higher in areas disturbed by feral horses.
Published Southern Alaska's national forests key to meeting climate, conservation goals
(via sciencedaily.com) Original source Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
Published A different take on phosphorus: Bacteria use organic phosphorus and release methane in the process
(via sciencedaily.com) Original source Some bacteria are able to tap into unusual sources of nutrients in the surface water of the oceans. This enables them to increase their primary production and extract more carbon dioxide from the atmosphere. In doing so, however, they release the potent greenhouse gas methane.
Published Device 'smells' seawater to discover, detect novel molecules
(via sciencedaily.com) Original source Under the ocean's surface, marine organisms are constantly releasing invisible molecules. Some of the chemical clues reveal which creatures are nearby, while others could be used someday as medications. Now, researchers report a proof-of-concept device that 'sniffs' seawater, trapping dissolved compounds for analyses. The team showed that the system could easily concentrate molecules that are present in underwater caves and holds promise for drug discovery in fragile ecosystems, including coral reefs.
Published 'Biodiversity time machine' provides insights into a century of loss
(via sciencedaily.com) Original source AI analysis shows pollution levels, extreme weather events and increasing temperatures devastates biodiversity in freshwater lakes.
Published Experiment shows biological interactions of microplastics in watery environment
(via sciencedaily.com) Original source Scientists have learned over the years that when aquatic organisms such as zooplankton become exposed to microplastics, they eat poorly. Research now shows that their plastic-induced eating difficulties also limit the ability of zooplankton to control algal proliferation. When algae bloom out of control, this presents a problem because some species produce toxins. Also, algal blooms can be associated with pea-soupy, unattractive bodies of water and contribute to hypoxia, a low-oxygen condition that may lead to fish kills.
Published We can save lives and millions with less nitrate in drinking water
(via sciencedaily.com) Original source Denmark could save lives and more than $300 million a year by reducing the amount of nitrate in its drinking water. An ever-growing body of research concludes that the amount of nitrate in some Danish boreholes increases the risk of colorectal cancer.
Published Food waste prevention in Europe can generate major footprint savings
(via sciencedaily.com) Original source New calculations show that the European countries have great potential for reducing the demand for global food resources and the associated GHG footprint. Researchers have estimated the climate footprint savings that may be obtained from reducing food loss and waste along Europe's food supply chain by 50 % by 2030.
Published How to eat our way out of the climate crisis
(via sciencedaily.com) Original source Researchers conducted a study to determine if replacing dietary fats from palm oil, soy and other agricultural crops with fats created synthetically in chemical or biological processes could help reduce climate change-causing greenhouse gases. The researchers' analysis finds a reduction in carbon emissions and other benefits, such the opening of agricultural lands to reforestation which benefits biodiversity and creates a carbon sink.
