Published Beetles and their biodiversity in dead wood
(via sciencedaily.com) Original source Which energy type promotes the biodiversity of beetles living in dead wood in the forest? That depends entirely on where the beetles are in the food chain.
Published Earth's first animals had particular taste in real estate
(via sciencedaily.com) Original source Even without body parts that allowed for movement, new research shows -- for the first time -- that some of Earth's earliest animals managed to be picky about where they lived.
Published Can a city store as much carbon as a forest?
(via sciencedaily.com) Original source A new tool helps show how growing cities can remain carbon neutral.
Published Exploring the underground connections between trees
(via sciencedaily.com) Original source Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.
Published Tooth enamel provides clues to hunter-gatherer lifestyle of Neanderthals
(via sciencedaily.com) Original source A study has given an intriguing glimpse of the hunting habits and diets of Neanderthals and other humans living in western Europe.
Published Small wildlife surveys can produce 'big picture' results
(via sciencedaily.com) Original source Small-scale wildlife surveys can reveal the health of entire ecosystems, new research shows.
Published Viruses could reshuffle the carbon cycle in a warming world
(via sciencedaily.com) Original source The roles microbes play in ecosystems are changing with global warming. Microbes are also affected by infection by viruses, but scientists know relatively little about how these viral infections could change how microbes react to warming. In this study, scientists describe different ways that increasing temperatures could affect viruses and their microbial hosts. Their preliminary models show that viruses could alter carbon balance, causing some ecosystems to switch from net carbon sources to net carbon sinks.
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 Quantum lidar prototype acquires real-time 3D images while fully submerged underwater
(via sciencedaily.com) Original source Researchers have demonstrated a prototype lidar system that uses quantum detection technology to acquire 3D images while submerged underwater. The high sensitivity of this system could allow it to capture detailed information even in extremely low-light conditions found underwater.
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 The future of data storage lies in DNA microcapsules
(via sciencedaily.com) Original source Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.
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.
