Published Mind-control robots a reality?
(via sciencedaily.com) Researchers have developed biosensor technology that will allow you to operate devices, such as robots and machines, solely through thought control.
Published A sowing, pruning, and harvesting robot for SynecocultureTM farming
(via sciencedaily.com) Synecoculture, a new farming method, involves growing mixed plant species together in high density. However, it requires complex operation since varying species with different growing seasons and growing speeds are planted on the same land. To address this need, researchers have developed a robot that can sow, prune, and harvest plants in dense vegetation growth. Its small, flexible body will help large-scale Synecoculture. This is an important step towards achieving sustainable farming and carbon neutrality.
Published New study provides first comprehensive look at oxygen loss on coral reefs
(via sciencedaily.com) A new study is providing an unprecedented examination of oxygen loss on coral reefs around the globe under ocean warming. The study captures the current state of hypoxia -- or low oxygen levels -- at 32 different sites, and reveals that hypoxia is already pervasive on many reefs.
Published How fishermen benefit from reversing evolution of cod
(via sciencedaily.com) Intense fishing and over-exploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. A new study shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity.
Published Resilient bug-sized robots keep flying even after wing damage
(via sciencedaily.com) Researchers have developed resilient artificial muscles that can enable insect-scale aerial robots to effectively recover flight performance after suffering severe damage.
Published Bird flu associated with hundreds of seal deaths in New England in 2022
(via sciencedaily.com) Researchers have found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.
Published Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots
(via sciencedaily.com) The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.
Published Robots can help improve mental wellbeing at work -- as long as they look right
(via sciencedaily.com) Robots can be useful as mental wellbeing coaches in the workplace -- but perception of their effectiveness depends in large part on what the robot looks like.
Published Researcher solves nearly 60-year-old game theory dilemma
(via sciencedaily.com) A researcher has solved a nearly 60-year-old game theory dilemma called the wall pursuit game, with implications for better reasoning about autonomous systems such as driver-less vehicles.
Published Researchers develop soft robot that shifts from land to sea with ease
(via sciencedaily.com) Most animals can quickly transition from walking to jumping to crawling to swimming if needed without reconfiguring or making major adjustments. Most robots cannot. But researchers have now created soft robots that can seamlessly shift from walking to swimming, for example, or crawling to rolling using a bistable actuator made of 3D-printed soft rubber containing shape-memory alloy springs that react to electrical currents by contracting, which causes the actuator to bend. The team used this bistable motion to change the actuator or robot's shape. Once the robot changes shape, it is stable until another electrical charge morphs it back to its previous configuration.
Published Study shows how biodiversity of coral reefs around the world changes with depth
(via sciencedaily.com) Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.
Published Minke whales are as small as a lunge-feeding baleen whale can be
(via sciencedaily.com) A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.
Published Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems
(via sciencedaily.com) An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.
Published Sea temperatures control the distributions of European marine fish
(via sciencedaily.com) An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.
Published Virtual reality games can be used as a tool in personnel assessment
(via sciencedaily.com) Fast gamers are more intelligent: Intelligence can be predicted through virtual reality games.
Published Unprecedented increase in ocean plastic since 2005 revealed by four decades of global analysis
(via sciencedaily.com) A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a new study.
Published Artificial intelligence (AI) reconstructs motion sequences of humans and animals
(via sciencedaily.com) Imagine for a moment, that we are on a safari watching a giraffe graze. After looking away for a second, we then see the animal lower its head and sit down. But, we wonder, what happened in the meantime? Computer scientists have found a way to encode an animal's pose and appearance in order to show the intermediate motions that are statistically likely to have taken place.
Published Major North American oil source yields clues to one of earth's deadliest mass extinctions
(via sciencedaily.com) Geologists studying the Bakken Shale Formation discovered a critical kill mechanism behind a series of extinctions some 350 million years ago.
Published Paleontologists flip the script on anemone fossils
(via sciencedaily.com) Billions of sea anemones adorn the bottom of the Earth's oceans -- yet they are among the rarest of fossils because their squishy bodies lack easily fossilized hard parts. Now a team of paleontologists has discovered that countless sea anemone fossils have been hiding in plain sight for nearly 50 years. It turns out that fossils long-interpreted as jellyfish were anemones. To do so, a team of scientists has simply turned the ancient animals upside down.
Published Does current shellfish anti-predator gear curb 'crunching' rays?
(via sciencedaily.com) It's not just humans who enjoy eating shellfish, so do marine rays. They like to 'crunch' on clams, which can sometimes take a big bite out of clammers' profits. Using aerial and underwater videos, researchers assessed the ability of the whitespotted eagle ray to interact with clams housed within a variety anti-predator materials. Whitespotted eagle rays have strong jaws, plate-like teeth and nimble pectoral fins, which make them formidable and highly maneuverable predators of clams.
