Published Plate tectonic processes in the Pacific and Atlantic during the Cretaceous period have shaped the Caribbean region to this day
(via sciencedaily.com) Original source Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active subduction zones come into being, however, is still under debate. An example of this is the volcanic Lesser Antilles arc in the Caribbean. A research team recently developed models that simulated the occurrences in the Caribbean region during the Cretaceous, when a subduction event in the Eastern Pacific led to the formation of a new subduction zone in the Atlantic. The computer simulations show how the collision of the old Caribbean plateau with the Greater Antilles arc contributed to the creation of this new Atlantic subduction zone. Some 86 million years ago, the triggered processes subsequently resulted in a major mantle flow and thus to the development of the Caribbean large igneous province.
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 A neuromorphic visual sensor can recognize moving objects and predict their path
(via sciencedaily.com) Original source The new smart sensor uses embedded information to detect motion in a single video frame.
Published Multi-compartment membranes for multicellular robots: Everybody needs some body
(via sciencedaily.com) Original source We typically think of robots as metal objects, filled with motors and circuits. But the field of molecular robotics is starting to change that. Like the formation of complex living organisms, molecular robots derive their form and functionality from assembled molecules stored in a single unit, i.e., a body. Yet manufacturing this body at the microscopic level is an engineering nightmare. Now, a team has created a simple workaround.
Published Research in Japan shows the way toward tactile and proximity sensing in large soft robots
(via sciencedaily.com) Original source To make human-robot interactions safer and more fruitful, robots should be capable of sensing their environment. In a recent study, researchers developed a novel robotic link with tactile and proximity sensing capabilities. Additionally, they created a simulation and learning framework that can be employed to train the robotic link to sense its environment. Their findings will pave the way to a future where humans and robots can operate harmoniously in close proximity.
Published It's all in the wrist: Energy-efficient robot hand learns how not to drop the ball
(via sciencedaily.com) Original source Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects -- and not drop them -- using just the movement of its wrist and the feeling in its 'skin'.
Published Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards
(via sciencedaily.com) Original source Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.
Published Table tennis brain teaser: Playing against robots makes our brains work harder
(via sciencedaily.com) Original source Brain scans taken during table tennis reveal differences in how we respond to human versus machine opponents.
Published Kids judge Alexa smarter than Roomba, but say both deserve kindness
(via sciencedaily.com) Original source Most kids know it's wrong to yell or hit someone, but what if that someone is a robot named Alexa? A new study asked kids how smart and sensitive they thought the virtual assistant was compared to a robotic vacuum. Four- to eleven-year-olds rated Alexa as more intelligent than the Roomba but felt neither deserve to be yelled at or otherwise harmed.
Published AI-equipped eyeglasses read silent speech
(via sciencedaily.com) Original source Researchers have developed a silent-speech recognition interface that uses acoustic-sensing and artificial intelligence to continuously recognize up to 31 unvocalized commands, based on lip and mouth movements.
Published Robots predict human intention for faster builds
(via sciencedaily.com) Original source Humans have a way of understandings others' goals, desires and beliefs, a crucial skill that allows us to anticipate people's actions. Taking bread out of the toaster? You'll need a plate. Sweeping up leaves? I'll grab the green trash can. This skill, often referred to as 'theory of mind,' comes easily to us as humans, but is still challenging for robots. But, if robots are to become truly collaborative helpers in manufacturing and in everyday life, they need to learn the same abilities. Computer science researchers aim to teach robots how to predict human preferences in assembly tasks, so they can one day help out on everything from building a satellite to setting a table.
Published Was plate tectonics occurring when life first formed on Earth?
(via sciencedaily.com) Original source Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely occurring more than 4.2 billion years ago when life is thought to have first formed on our planet. This finding could prove beneficial in the search for life on other planets.
Published New cyber software can verify how much knowledge AI really knows
(via sciencedaily.com) Original source With a growing interest in generative artificial intelligence (AI) systems worldwide, researchers have created software that is able to verify how much information an AI farmed from an organization's digital database.
Published Origami-inspired robots can sense, analyze and act in challenging environments
(via sciencedaily.com) A multidisciplinary team has created a new fabrication technique for fully foldable robots that can perform a variety of complex tasks without relying on semiconductors.
Published Robotic hand can identify objects with just one grasp
(via sciencedaily.com) Newly created soft-rigid robotic fingers incorporate powerful sensors along their entire length, enabling them to produce a robotic hand that could accurately identify objects after only one grasp.
Published Forgive or forget: What happens when robots lie?
(via sciencedaily.com) Original source Student researchers investigate how intentional robot deception affects trust, examining the effectiveness of apologies after robots lie.
Published Can AI predict how you'll vote in the next election?
(via sciencedaily.com) Artificial intelligence technologies like ChatGPT are seemingly doing everything these days: writing code, composing music, and even creating images so realistic you'll think they were taken by professional photographers. Add thinking and responding like a human to the conga line of capabilities. A recent study proves that artificial intelligence can respond to complex survey questions just like a real human.
Published Preschoolers prefer to learn from a competent robot than an incompetent human
(via sciencedaily.com) Researchers found that preschoolers prefer learning from what they perceive as a competent robot over an incompetent human. This study is the first to use both a human speaker and a robot to see if children deem social affiliation and similarity more important than competency when choosing which source to trust and learn from.
