Published Cats purrfectly demonstrate what it takes to trust robots
(via sciencedaily.com) Original source Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction.
Published Today's world: Fastest rate of carbon dioxide rise over the last 50,000 years
(via sciencedaily.com) Original source Today's rate of atmospheric carbon dioxide increase is 10 times faster than at any other point in the past 50,000 years, researchers have found through a detailed chemical analysis of ancient Antarctic ice.
Published When consumers would prefer a chatbot over a person
(via sciencedaily.com) Original source Actually, sometimes consumers don't want to talk to a real person when they're shopping online, a new study suggests. In fact, what they really want is a chatbot that makes it clear that it is not human at all. In a new study, researchers found that people preferred interacting with chatbots when they felt embarrassed about what they were buying online -- items like antidiarrheal medicine or, for some people, skin care products.
Published Transformation of ocean management is underway
(via sciencedaily.com) Original source Despite its benefits and recognition as a keystone practice of ocean stewardship and conservation, adoption of ecosystem-based management has been slow to take hold. To support this change in ocean management, a group of researchers and practitioners investigated the global progress of marine EBM initiatives.
Published Ocean biodiversity work needs improvement
(via sciencedaily.com) Original source An international collaboration says the world's largest marine protected areas aren't collectively delivering the biodiversity benefits they could be because of slow implementation of management strategies and a failure to restrict the most impactful human activities.
Published A better way to control shape-shifting soft robots
(via sciencedaily.com) Original source A new machine-learning technique can train and control a reconfigurable soft robot that can dynamically change its shape to complete a task. The researchers also built a simulator that can evaluate control algorithms for shape-shifting soft robots.
Published Robotic system feeds people with severe mobility limitations
(via sciencedaily.com) Original source Researchers have developed a robotic feeding system that uses computer vision, machine learning and multimodal sensing to safely feed people with severe mobility limitations, including those with spinal cord injuries, cerebral palsy and multiple sclerosis.
Published Generative AI that imitates human motion
(via sciencedaily.com) Original source Walking and running is notoriously difficult to recreate in robots. Now, a group of researchers has overcome some of these challenges by creating an innovative method that employs central pattern generators -- neural circuits located in the spinal cord that generate rhythmic patterns of muscle activity -- with deep reinforcement learning. The method not only imitates walking and running motions but also generates movements for frequencies where motion data is absent, enables smooth transition movements from walking to running, and allows for adapting to environments with unstable surfaces.
Published Human activity is making it harder for scientists to interpret oceans' past
(via sciencedaily.com) Original source New research shows human activity is significantly altering the ways in which marine organisms are preserved, with lasting effects that can both improve and impair the fossil record.
Published New study finds AI-generated empathy has its limits
(via sciencedaily.com) Original source Conversational agents (CAs) such as Alexa and Siri are designed to answer questions, offer suggestions -- and even display empathy. However, new research finds they do poorly compared to humans when interpreting and exploring a user's experience.
Published Marine bacteria team up to produce a vital vitamin
(via sciencedaily.com) Original source Two species of marine bacteria from the North Sea have established an unusual and sometimes destructive relationship to produce the important vitamin B12. The team's experiments show that the two microbial species have developed a coordinated strategy to obtain the scarce but essential vitamin.
Published Caterbot? Robatapillar? It crawls with ease through loops and bends
(via sciencedaily.com) Original source Engineers created a catapillar-shaped robot that splits into segments and reassembles, hauls cargo, and crawls through twisting courses.
Published Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs
(via sciencedaily.com) Original source A new study shows stony coral tissue loss disease is causing drastic changes in the Caribbean's population of corals, which is sure to disrupt the delicate balance of the ecosystem and threaten marine biodiversity and coastal economies.
Published Ice shelves fracture under weight of meltwater lakes
(via sciencedaily.com) Original source Heavy pooling meltwater can fracture ice, potentially leading to ice shelf collapse.
Published Stretchable e-skin could give robots human-level touch sensitivity
(via sciencedaily.com) Original source A stretchy electronic skin could equip robots and other devices with the same softness and touch sensitivity as human skin, opening up new possibilities to perform tasks that require a great deal of precision and control of force.
Published For microscopic organisms, ocean currents act as 'expressway' to deeper depths
(via sciencedaily.com) Original source Some of the ocean's tiniest organisms get swept into underwater currents that act as a conduit that shuttles them from the sunny surface to deeper, darker depths where they play a huge role in affecting the ocean's chemistry and ecosystem, according to new research.
Published Human activity is causing toxic thallium to enter the Baltic sea, according to new study
(via sciencedaily.com) Original source Human activities account for 20% to more than 60% of toxic thallium entering the Baltic Sea over the past eight decades, according to new research. Currently, the amount of thallium, which is considered the most toxic metal for mammals, remains low in Baltic seawater. Much of the thallium in the Baltic, which is the largest human-induced hypoxic area on Earth, has been accumulated in the sediment thanks to sulfide minerals.
Published Robots invited to help make wind turbine blades
(via sciencedaily.com) Original source Researchers have successfully leveraged robotic assistance in the manufacture of wind turbine blades, allowing for the elimination of difficult working conditions for humans and the potential to improve the consistency of the product.
Published Random robots are more reliable
(via sciencedaily.com) Original source New algorithm encourages robots to move more randomly to collect more diverse data for learning. In tests, robots started with no knowledge and then learned and correctly performed tasks within a single attempt. New model could improve safety and practicality of self-driving cars, delivery drones and more.
Published Mystery behind huge opening in Antarctic sea ice solved
(via sciencedaily.com) Original source Researchers have discovered the missing piece of the puzzle behind a rare opening in the sea ice around Antarctica, which was nearly twice the size of Wales and occurred during the winters of 2016 and 2017. A study reveals a key process that had eluded scientists as to how the opening, called a polynya, was able to form and persist for several weeks.
