Published How a horse whisperer can help engineers build better robots
(via sciencedaily.com) Original source New research shows us that age-old interactions between people and their horses can teach us something about building robots designed to improve our lives.
Published Ocean ecosystem: Mixotrophic microorganisms play key role
(via sciencedaily.com) Original source Researchers have identified a previously unknown group of bacteria, called UBA868, as key players in the energy cycle of the deep ocean. They are significantly involved in the biogeochemical cycle in the marine layer between 200 and 1000 meters.
Published Jellyfish-like robots could one day clean up the world's oceans
(via sciencedaily.com) Original source Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.
Published Massive iceberg discharges during the last ice age had no impact on nearby Greenland, raising new questions about climate dynamics
(via sciencedaily.com) Original source New findings suggest that Heinrich Events had no discernible impact on temperatures in Greenland, which could have repercussions for scientists' understanding of past climate dynamics.
Published Cheaper method for making woven displays and smart fabrics -- of any size or shape
(via sciencedaily.com) Original source Researchers have developed next-generation smart textiles -- incorporating LEDs, sensors, energy harvesting, and storage -- that can be produced inexpensively, in any shape or size, using the same machines used to make the clothing we wear every day.
Published Nanowire networks learn and remember like a human brain
(via sciencedaily.com) Original source Scientists have demonstrated nanowire networks can exhibit both short- and long-term memory like the human brain.
Published Whales stop by Gold Coast bay for day spa fix with full body scrubs
(via sciencedaily.com) Original source A new Griffith University study has found that humpback whales will use sandy, shallow bay areas to 'roll' around in sandy substrates to remove dead skin cells on their return journeys south to cooler waters. Using data and footage collected from the tags, whales were observed performing full and side rolls in up to 49m water depth on the sea floor that was lined with fine sand or rubble.
Published Arctic ice algae heavily contaminated with microplastics
(via sciencedaily.com) Original source The alga Melosira arctica, which grows under Arctic sea ice, contains ten times as many microplastic particles as the surrounding seawater. This concentration at the base of the food web poses a threat to creatures that feed on the algae at the sea surface. Clumps of dead algae also transport the plastic with its pollutants particularly quickly into the deep sea -- and can thus explain the high microplastic concentrations in the sediment there.
Published ChatGPT is still no match for humans when it comes to accounting
(via sciencedaily.com) Original source ChatGPT faced off against students on accounting assessments. Students scored an overall average of 76.7%, compared to ChatGPT's score of 47.4%. On a 11.3% of questions, ChatGPT scored higher than the student average, doing particularly well on AIS and auditing. But the AI bot did worse on tax, financial, and managerial assessments, possibly because ChatGPT struggled with the mathematical processes required for the latter type.
Published AI system can generate novel proteins that meet structural design targets
(via sciencedaily.com) Original source A new machine-learning system can generate protein designs with certain structural features, and which do not exist in nature. These proteins could be utilized to make materials that have similar mechanical properties to existing materials, like polymers, but which would have a much smaller carbon footprint.
Published Quantum entanglement could make accelerometers and dark matter sensors more accurate
(via sciencedaily.com) Original source The 'spooky action at a distance' that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones.
Published Polar ice sheet melting records have toppled during the past decade
(via sciencedaily.com) Original source The seven worst years for polar ice sheets melting and losing ice have occurred during the past decade, according to new research, with 2019 being the worst year on record. The seven worst years for polar ice sheets melting and losing ice have occurred during the past decade, according to new research, with 2019 being the worst year on record. The melting ice sheets now account for a quarter of all sea level rise -- a fivefold increase since the 1990's -- according to researchers who have combined 50 satellite surveys of Antarctica and Greenland taken between 1992 and 2020, funded by NASA and the European Space Agency.
Published Immediate carbon cuts, common marine heatwave terminology urged
(via sciencedaily.com) Original source Oceanographers provide a reality check on the limitations of carbon dioxide removal and a warning that marine heatwaves need clear definitions so communities can adapt.
Published Scientists identify 2022 sea urchin killer
(via sciencedaily.com) Original source A team of researchers has identified a single-celled organism called a ciliate as the cause of a massive die-off event to a marine animal vital to coral reef health.
Published A once-stable glacier in Greenland is now rapidly disappearing
(via sciencedaily.com) Original source As climate change causes ocean temperatures to rise, one of Greenland's previously most stable glaciers is now retreating at an unprecedented rate, according to a new study.
Published Rock, paper, scissors: Searching for stronger nonlocality using quantum computers
(via sciencedaily.com) Original source In the quantum world particles can instantaneously know about each other's state, even when separated by large distances. This is known as nonlocality. Now, A research group has produced some interesting findings on the Hardy nonlocality that have important ramifications for understanding quantum mechanics and its potential applications in communications.
Published Long-distance quantum teleportation enabled by multiplexed quantum memories
(via sciencedaily.com) Original source Researchers report having achieved quantum teleportation from a photon to a solid-state qubit over a distance of 1km, with a novel approach using multiplexed quantum memories.
Published Scientists discover pristine deep-sea coral reefs in the Galápagos Marine Reserve
(via sciencedaily.com) Original source Scientists have discovered extensive, ancient deep-sea coral reefs within the Galápagos Marine Reserve (GMR) -- the first of their kind ever to be documented inside the marine protected area (MPA) since it was established in 1998. The first reef observed was found at 400-600m (1,310-1,970 feet) depth at the summit of a previously unmapped seamount in the central part of the archipelago and supports a breathtaking mix of deep marine life.
Published Team designs four-legged robotic system that can walk a balance beam
(via sciencedaily.com) Original source Researchers have designed a system that makes an off-the-shelf quadruped robot nimble enough to walk a narrow balance beam -- a feat that is likely the first of its kind.
Published Coastal species persist on high seas on floating plastic debris
(via sciencedaily.com) Original source The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.
