Published Sulfur and the origin of life
(via sciencedaily.com) Original source A new study shines a spotlight on sulfur, a chemical element that, while all familiar, has proved surprisingly resistant to scientific efforts in probing its role in the origin of life.
Published Robot ANYmal can do parkour and walk across rubble
(via sciencedaily.com) Original source The quadrupedal robot ANYmal went back to school and has learned a lot. Researchers used machine learning to teach it new skills: the robot can now climb over obstacles and successfully negotiate pitfalls.
Published Mars attracts: How Earth's interactions with the red planet drive deep-sea circulation
(via sciencedaily.com) Original source Scientists have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulation. The patterns they discover suggest that warming seas could produce deep whirpools in ocean currents.
Published Scientists propose new theory that explains sand ripples on Mars and on Earth
(via sciencedaily.com) Original source Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?
Published How do neural networks learn? A mathematical formula explains how they detect relevant patterns
(via sciencedaily.com) Original source Neural networks have been powering breakthroughs in artificial intelligence, including the large language models that are now being used in a wide range of applications, from finance, to human resources to healthcare. But these networks remain a black box whose inner workings engineers and scientists struggle to understand. Now, a team has given neural networks the equivalent of an X-ray to uncover how they actually learn.
Published Robotic interface masters a soft touch
(via sciencedaily.com) Original source Researchers have developed a haptic device capable of reproducing the softness of various materials, from a marshmallow to a beating heart, overcoming a deceptively complex challenge that has previously eluded roboticists.
Published Going top shelf with AI to better track hockey data
(via sciencedaily.com) Original source Researchers got a valuable assist from artificial intelligence (AI) tools to help capture and analyze data from professional hockey games faster and more accurately than ever before, with big implications for the business of sports.
Published The role of machine learning and computer vision in Imageomics
(via sciencedaily.com) Original source A new field promises to usher in a new era of using machine learning and computer vision to tackle small and large-scale questions about the biology of organisms around the globe.
Published New study reveals insight into which animals are most vulnerable to extinction due to climate change
(via sciencedaily.com) Original source In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
Published Rock weathering and climate: Low-relief mountain ranges are largest carbon sinks
(via sciencedaily.com) Original source For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'
Published Method rapidly verifies that a robot will avoid collisions
(via sciencedaily.com) Original source A new safety-check technique can prove with 100 percent accuracy that a planned robot motion will not result in a collision. The method can generate a proof in seconds and does so in a way that can be easily verified by a human.
Published AI can speed design of health software
(via sciencedaily.com) Original source Artificial intelligence helped clinicians to accelerate the design of diabetes prevention software, a new study finds.
Published New dressing robot can 'mimic' the actions of care-workers
(via sciencedaily.com) Original source Scientists have developed a new robot that can 'mimic' the two-handed movements of care-workers as they dress an individual.
Published Geologists explore the hidden history of Colorado's Spanish Peaks
(via sciencedaily.com) Original source A team has collected dozens of samples from across southeastern Colorado, and their results could help to answer an enduring mystery: What made Colorado's High Plains so high?
Published Mercury rising: Study sheds new light on ancient volcanoes' environmental impact
(via sciencedaily.com) Original source Massive volcanic events in Earth's history that released large amounts of carbon into the atmosphere frequently correlate with periods of severe environmental change and mass extinctions. A new method to estimate how much and how rapidly carbon was released by the volcanoes could improve our understanding of the climate response, according to an international team.
Published 80 mph speed record for glacier fracture helps reveal the physics of ice sheet collapse
(via sciencedaily.com) Original source New research documents the fastest-known large-scale breakage along an Antarctic ice shelf. A 6.5-mile crack formed in 2012 over 5-and-a-half minutes, showing that ice shelves can effectively shatter -- though the speed is limited by seawater rushing in. The results help inform large-scale ice sheet models and projections of future sea level rise.
Published New AI model could streamline operations in a robotic warehouse
(via sciencedaily.com) Original source Researchers applied deep-learning approaches from vehicle routing to streamline planning trajectories for robots in an e-commerce warehouse. Their method breaks the problem down into smaller chunks and then predicts the best chunks to solve with traditional algorithms.
Published A novel method for easy and quick fabrication of biomimetic robots with life-like movement
(via sciencedaily.com) Original source Ultraviolet-laser processing is a promising technique for developing intricate microstructures, enabling complex alignment of muscle cells, required for building life-like biohybrid actuators. Compared to traditional complex methods, this innovative technique enables easy and quick fabrication of microstructures with intricate patterns for achieving different muscle cell arrangements, paving the way for biohybrid actuators capable of complex, flexible movements.
Published UBC Okanagan researchers look to the past to improve construction sustainability
(via sciencedaily.com) Original source Researchers are revisiting old building practices -- the use of by-products and cast-offs -- as a way to improve building materials and sustainability of the trade. A technique known as rammed earth construction uses materials that are alternatives to cement and are often more readily available in the environment. One such alternative is wood fly ash, a by-product of pulp mills and coal-fired power plants.
Published Biggest Holocene volcano eruption found by seabed survey
(via sciencedaily.com) Original source A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.
