Published Tiny roundworms carve out unique parasitic niche inside pseudoscorpion's protective covering
(via sciencedaily.com) Original source In a parasitic first, a Baltic amber specimen has revealed that millions of years ago tiny worms known as nematodes were living inside of and feeding on the outer protective layer of pseudoscorpions.
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 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 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 Exploring three frontiers in marine biomass and blue carbon capture
(via sciencedaily.com) Original source A new study offers first-time insights into three emerging climate innovations to safeguard or increase the carbon naturally captured by ocean and coastal ecosystems: rapid interventions to save the Great Barrier Reef, satellite-tracked kelp beds in the deep ocean, and seagrass nurseries in the United Kingdom.
Published Summer droughts in Northern hemisphere increasingly likely as seasonal streamflows change
(via sciencedaily.com) Original source Declining snowfall is changing the seasonal patterns of streamflow throughout the Northern hemisphere boosting chances of water shortages in the summer, scientists have found.
Published Some countries could meet their total electricity needs from floating solar panels
(via sciencedaily.com) Original source Floating solar photovoltaic panels could supply all the electricity needs of some countries, new research has shown. The researchers calculated the daily electrical output for floating photovoltaics (FPV) on nearly 68,000 lakes and reservoirs around the world, using available climate data for each location.
Published Gigantic Jurassic pterosaur fossil unearthed in Oxfordshire, UK
(via sciencedaily.com) Original source A team of palaeontologists has discovered a fossil of a gigantic flying reptile from the Jurassic period with an estimated wingspan of more than three metres -- making it one of the largest pterosaurs ever found from that era.
Published Microscopic defects in ice shape how massive glaciers flow, study shows
(via sciencedaily.com) Original source A glacier's flow depends on how microscopic defects move through the ice, according to new research that also yielded a new model for predicting how glaciers will flow, ultimately contributing to sea-level rise.
Published Mapping the seafloor sediment superhighway
(via sciencedaily.com) Original source A new scientific model is giving researchers an unprecedented, global look at the activities of clams, worms, and other invertebrate animals that burrow at the bottom of the ocean.
Published Shape and depth of ocean floor profoundly influence how carbon is stored there
(via sciencedaily.com) Original source The movement of carbon between the atmosphere, oceans and continents -- or carbon cycle -- regulates Earth's climate, with the ocean playing a major role in carbon sequestration. A new study finds that the shape and depth of the ocean floor explain up to 50% of the changes in depth at which carbon has been sequestered there over the past 80 million years. While these changes have been previously attributed to other causes, the new finding could inform ongoing efforts to combat climate change through marine carbon sequestration.
Published Crucial shift in River Nile's evolution during ancient Egypt discovered
(via sciencedaily.com) Original source Researchers have explored how the River Nile evolved over the past 11,500 years and how changes in its geography could have helped shape the fortunes of ancient Egyptian civilization. Research reveals a major shift in the Nile around four thousand years ago, after which the floodplain in the Nile Valley around Luxor greatly expanded.
Published Greenhouses cover more and more of Earth's surface
(via sciencedaily.com) Original source Greenhouse cultivation is booming globally, especially in the Global South -- and across one country in particular. This is revealed in a new study that deploys detailed satellite imagery and AI to map greenhouses across the planet. According to the researchers, the development is a source of both promise and concern.
Published Fresh findings: Earliest evidence of life-bringing freshwater on Earth
(via sciencedaily.com) Original source New research has found evidence that fresh water on Earth, which is essential for life, appeared about four billion years ago -- five hundred million years earlier than previously thought.
Published How sharks survived a major spike in Earth's temperature
(via sciencedaily.com) Original source The sharks we know today as the open ocean's top predators evolved from stubby bottom dwellers during a dramatic episode of global warming millions of years ago.
Published Researchers call for return of Sumas Lake following devastating 2021 floods
(via sciencedaily.com) Original source A new proposal has emerged in response to the November 2021 floods that swept Sumas Prairie in the Fraser Valley, British Columbia, causing mass evacuations and millions in damages. Instead of rebuilding the dykes to manage water flows and prevent future floods, scientists, along with members of the Sumas First Nation and other research partners, suggest an alternative: let Sumas Lake, which was drained in the early 1920s and converted into the farmland known as Sumas Prairie, return to its natural state. This can be done by buying out properties on the lakebed -- a solution that is projected to cost around $1 billion, less than half of the estimated $2.4 billion cost of repairing the dykes and installing a new pump station.
Published An unlikely hero in evolution: Worms
(via sciencedaily.com) Original source One of Earth's most consequential bursts of biodiversity -- a 30-million-year period of explosive evolutionary changes spawning innumerable new species -- may have the most modest of creatures to thank for the vital stage in life's history: worms.
