Published New soft robots roll like tires, spin like tops and orbit like moons
(via sciencedaily.com) Original source Researchers have developed a new soft robot design that engages in three simultaneous behaviors: rolling forward, spinning like a record, and following a path that orbits around a central point. The device, which operates without human or computer control, holds promise for developing soft robotic devices that can be used to navigate and map unknown environments.
Published Protecting coral 'nurseries' as important as safeguarding established coral reefs
(via sciencedaily.com) Original source New research in the southwestern part of Hawai'i Island shows that identifying and protecting marine ecosystems both down-current and up-current of coral reefs, specifically areas where coral larvae are more likely to survive and thrive, is crucial to future coral conservation and restoration efforts -- especially as reefs face increasing pressure from the devastating effects of climate change.
Published Fastest swimming insect could inspire uncrewed boat designs
(via sciencedaily.com) Original source Whirligig beetles, the world's fastest-swimming insect, achieve surprising speeds by employing a strategy shared by fast-swimming marine mammals and waterfowl, according to a new study that rewrites previous explanations of the physics involved.
Published The snail or the egg?
(via sciencedaily.com) Original source Animals reproduce in one of two distinct ways: egg-laying or live birth. By studying an evolutionarily recent transition from egg-laying to live-bearing in a marine snail, collaborative research has shed new light on the genetic changes that allow organisms to make the switch.
Published Male southern elephant seals are picky eaters
(via sciencedaily.com) Original source New research suggests these large marine mammals are extremely fussy and only eat their favorite foods.
Published The choreography connecting kelp forests to the beach
(via sciencedaily.com) Original source A new study uncovers a symphony of synchrony between the kelp forest and beach, with broader implications for the beach food web as the climate changes.
Published Vitamin discovered in rivers may offer hope for salmon suffering from thiamine deficiency disease
(via sciencedaily.com) Original source Researchers have discovered vitamin B1 produced by microbes in rivers, findings that may offer hope for vitamin-deficient salmon populations.
Published 'Giant' predator worms more than half a billion years old discovered in North Greenland
(via sciencedaily.com) Original source Fossils of a new group of animal predators have been located in the Early Cambrian Sirius Passet fossil locality in North Greenland. These large worms may be some of the earliest carnivorous animals to have colonized the water column more than 518 million years ago, revealing a past dynasty of predators that scientists didn't know existed.
Published Could an electric nudge to the head help your doctor operate a surgical robot?
(via sciencedaily.com) Original source People who received gentle electric currents on the back of their heads learned to maneuver a robotic surgery tool in virtual reality and then in a real setting much more easily than people who didn't receive those nudges, a new study shows.
Published Fish display distinct individual behaviors when swimming to find food
(via sciencedaily.com) Original source Fish from the same species can evolve their sense of smell and display individual foraging 'personalities' to successfully find food in different habitats.
Published AI's memory-forming mechanism found to be strikingly similar to that of the brain
(via sciencedaily.com) Original source An interdisciplinary team consisting of researchers has revealed a striking similarity between the memory processing of artificial intelligence (AI) models and the hippocampus of the human brain. This new finding provides a novel perspective on memory consolidation, which is a process that transforms short-term memories into long-term ones, in AI systems.
Published Global inventory of sound production brings us one step closer to understanding aquatic ecosystems
(via sciencedaily.com) Original source Our understanding of which aquatic species produce sounds just took a big step forward. Scientists have created an inventory of species confirmed or expected to produce sound underwater.
Published Some coral species might be more resilient to climate change than previously thought
(via sciencedaily.com) Original source Some coral species can be resilient to marine heat waves by 'remembering' how they lived through previous ones, research suggests.
Published 15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems
(via sciencedaily.com) Original source Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.
Published Artificial intelligence can predict events in people's lives
(via sciencedaily.com) Original source Artificial intelligence can analyze registry data on people's residence, education, income, health and working conditions and, with high accuracy, predict life events.
Published AI study reveals individuality of tongue's surface
(via sciencedaily.com) Original source Artificial Intelligence (AI) and 3D images of the human tongue have revealed that the surface of our tongues are unique to each of us, new findings suggest. The results offer an unprecedented insight into the biological make-up of our tongue's surface and how our sense of taste and touch differ from person to person.
Published Cognitive strategies for augmenting the body with a wearable, robotic arm
(via sciencedaily.com) Original source Scientists show that breathing may be used to control a wearable extra robotic arm in healthy individuals, without hindering control of other parts of the body.
Published Can AI be too good to use?
(via sciencedaily.com) Original source Much of the discussion around implementing artificial intelligence systems focuses on whether an AI application is 'trustworthy': Does it produce useful, reliable results, free of bias, while ensuring data privacy? But a new article poses a different question: What if an AI is just too good?
Published Artificial intelligence systems excel at imitation, but not innovation
(via sciencedaily.com) Original source Artificial intelligence (AI) systems are often depicted as sentient agents poised to overshadow the human mind. But AI lacks the crucial human ability of innovation, researchers have found.
Published Whale-SETI: Groundbreaking encounter with humpback whales reveals potential for nonhuman intelligence communication
(via sciencedaily.com) Original source A team of scientists had a close encounter with a non-human (aquatic) intelligence. The Whale-SETI team has been studying humpback whale communication systems in an effort to develop intelligence filters for the search for extraterrestrial intelligence. In response to a recorded humpback 'contact' call played into the sea via an underwater speaker, a humpback whale named Twain approached and circled the team's boat, while responding in a conversational style to the whale 'greeting signal.' During the 20-minute exchange, Twain responded to each playback call and matched the interval variations between each signal.
