Published Cleanup of inactive Gulf of Mexico wells estimated at $30 billion
(via sciencedaily.com) Original source A new article examines the cost to plug 14,000 wells that are inactive, have not produced for five years and are unlikely to be reactivated in the Gulf of Mexico region, which is the epicenter of U.S. offshore oil and gas operations.
Published First observational evidence of beaufort gyre stabilization, which could be precursor to huge freshwater release
(via sciencedaily.com) Original source A new study provides the first observational evidence of the stabilization of the anti-cyclonic Beaufort Gyre, which is the dominant circulation of the Canada Basin and the largest freshwater reservoir in the Arctic Ocean.
Published The influence of AI on trust in human interaction
(via sciencedaily.com) Original source As AI becomes increasingly realistic, our trust in those with whom we communicate may be compromised. Researchers at the University of Gothenburg have examined how advanced AI systems impact our trust in the individuals we interact with.
Published Archaea in a warming climate become less diverse, more predictable
(via sciencedaily.com) Original source Using a long-term multifactor experimental field site researchers showed that experimental warming of a tallgrass prairie ecosystem significantly altered the community structure of soil archaea and reduced their taxonomic and phylogenetic diversity.
Published Single approach on wild horses
(via sciencedaily.com) Original source Because contrasting societal views have created an approach that simultaneously manages horses on the range as wildlife, livestock and pets, current U.S. government programs are incapable of succeeding, according to researchers.
Published Scurrying centipedes inspire many-legged robots that can traverse difficult landscapes
(via sciencedaily.com) Original source Intrigued to see if the many limbs could be helpful for locomotion in this world, a team of physicists, engineers, and mathematicians are using this style of movement to their advantage. They developed a new theory of multilegged locomotion and created many-legged robotic models, discovering the robot with redundant legs could move across uneven surfaces without any additional sensing or control technology as the theory predicted.
Published AI could run a million microbial experiments per year
(via sciencedaily.com) Original source Automation uncovers combinations of amino acids that feed two bacterial species and could tell us much more about the 90% of bacteria that humans have hardly studied. An artificial intelligence system enables robots to conduct autonomous scientific experiments -- as many as 10,000 per day -- potentially driving a drastic leap forward in the pace of discovery in areas from medicine to agriculture to environmental science.
Published Scientists begin to unravel global role of atmospheric dust in nourishing oceans
(via sciencedaily.com) Original source New research begins to unravel the role dust plays in nourishing global ocean ecosystems while helping regulate atmospheric carbon dioxide levels.
Published How seaweed has been misleading scientists about reef health
(via sciencedaily.com) Original source For decades, scientists have used the amount of seaweed at the ocean's surface as a proxy for the health of coral reefs below. However, a new global study of more than 1,200 marine locations over a 16-year period reveals that this approach has been misleading -- and may even have hidden signs of reef stress.
Published Vanishing glaciers threaten alpine biodiversity
(via sciencedaily.com) Original source With glaciers melting at unprecedented rates due to climate change, invertebrates that live in the cold meltwater rivers of the European Alps will face widespread habitat loss, warn researchers. Many of the species are likely to become restricted to cold habitats that will only persist higher in the mountains, and these areas are also likely to see pressures from the skiing and tourism industries or from the development of hydroelectric plants.
Published Marine seagrass meadows show resilience to 'bounce back' after die-offs
(via sciencedaily.com) Original source A study in Florida Bay, one of the largest global contiguous seagrass systems, examined if a phytotoxin that accumulates as seagrass ecosystems become more enriched in nutrients prevents a marine seagrass, turtlegrass, from recruiting into open bare sediment following die-off events. While they do 'bounce back,' long-term monitoring indicates the timeframe for recovery after major die-off events is at least a decade. Turtlegrass can successfully recruit into open bare sediment following die-off events due to biomass partitioning.
Published Indo-Pacific corals more resilient to climate change than Atlantic corals
(via sciencedaily.com) Original source In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic.
Published Deep neural network provides robust detection of disease biomarkers in real time
(via sciencedaily.com) Original source A lab has developed a deep neural network that improves the accuracy of their unique devices for detecting pathogen biomarkers.
Published A touch-responsive fabric armband -- for flexible keyboards, wearable sketchpads
(via sciencedaily.com) Original source It's time to roll up your sleeves for the next advance in wearable technology -- a fabric armband that's actually a touch pad. Researchers say they have devised a way to make playing video games, sketching cartoons and signing documents easier. Their proof-of-concept silk armband turns a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material interprets what a user draws or types and converts it into images on a computer.
Published Researchers discover that the ice cap is teeming with microorganisms
(via sciencedaily.com) Original source Greenlandic ice is teeming with life, both on the surface and underneath. There are microscopic organisms that until recently science had no idea existed. There is even evidence to suggest that the tiny creatures color the ice and make it melt faster.
Published The science behind the life and times of the Earth's salt flats
(via sciencedaily.com) Original source Researchers have characterized two different types of surface water in the hyperarid salars -- or salt flats -- that contain much of the world's lithium deposits. This new characterization represents a leap forward in understanding how water moves through such basins, and will be key to minimizing the environmental impact on such sensitive, critical habitats.
Published Machine learning helps scientists identify the environmental preferences of microbes
(via sciencedaily.com) Original source A machine-learning approach can give scientists insight into the environmental preferences of microbes, based only on their genes. The approach has practical research implications: it could help researchers more efficiently grow bacteria in the laboratory. It could also lead to smarter use of microbes in agriculture, ecological restoration, and even probiotics.
Published Mushrooms and their post-rain, electrical conversations
(via sciencedaily.com) Original source Certain types of fungi can communicate with each other via electrical signals. But much remains unknown about how and when they do so. A group of researchers recently headed to the forest to measure the electrical signals of Laccaria bicolor mushrooms, finding that their electrical signals increased following rainfall.
Published Ecosystem evolution in Africa
(via sciencedaily.com) Original source New research pushes back the oldest evidence of C4 grass-dominated habitats in Africa -- and globally -- by more than 10 million years, with important implications for primate evolution and the origins of tropical C4 grasslands and savanna ecosystems across the African continent and around the world.
Published The reasons why insect numbers are decreasing
(via sciencedaily.com) Original source Researchers are investigating the causes and consequences of the worldwide insect decline as well as considering potential countermeasures.
