Published Light-controlled artificial maple seeds could monitor the environment even in hard-to-reach locations
(via sciencedaily.com) Original source Researchers have developed a tiny robot replicating the aerial dance of falling maple seeds. In the future, this robot could be used for real-time environmental monitoring or delivery of small samples even in inaccessible terrain such as deserts, mountains or cliffs, or the open sea. This technology could be a game changer for fields such as search-and-rescue, endangered species studies, or infrastructure monitoring.
Published Projected loss of brown macroalgae and seagrasses with global environmental change
(via sciencedaily.com) Original source Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.
Published Antarctic ice shelves hold twice as much meltwater as previously thought
(via sciencedaily.com) Original source Slush -- water-soaked snow -- makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models. The findings could have profound implications for ice shelf stability and sea level rise.
Published Researchers address ocean paradox with 55 gallons of fluorescent dye
(via sciencedaily.com) Original source Researchers have directly measured cold, deep water upwelling via turbulent mixing along the slope of a submarine canyon in the Atlantic Ocean.
Published El Niño forecasts extended to 18 months with innovative physics-based model
(via sciencedaily.com) Original source As more attention is drawn to possible severe weather around the world scientists are looking to improve planning for possible droughts, floods and other scenarios. A team of researchers created a new tool that will allow forecasting of El Nino Southern Oscillation by up to 18 months.
Published Underwater mountains have a big impact on ocean circulation
(via sciencedaily.com) Original source Colossal undersea mountains, towering up to thousands of metres high, stir up deep sea currents: impacting how our ocean stores heat and carbon. An international team used numerical modelling to quantify how underwater turbulence around these mountains, called seamounts, influences ocean circulation; finding it is an important mechanism in ocean mixing and one that is missing from climate models used in policymaking.
Published Researchers develop new training technique that aims to make AI systems less socially biased
(via sciencedaily.com) Original source Researchers have created a new, cost-effective training technique for artificial intelligence systems that aims to make them less socially biased.
Published Next platform for brain-inspired computing
(via sciencedaily.com) Original source Computers have come so far in terms of their power and potential, rivaling and even eclipsing human brains in their ability to store and crunch data, make predictions and communicate. But there is one domain where human brains continue to dominate: energy efficiency.
Published Robots face the future
(via sciencedaily.com) Original source Researchers have found a way to bind engineered skin tissue to the complex forms of humanoid robots. This brings with it potential benefits to robotic platforms such as increased mobility, self-healing abilities, embedded sensing capabilities and an increasingly lifelike appearance. Taking inspiration from human skin ligaments, the team included special perforations in a robot face, which helped a layer of skin take hold.
Published Meet CARMEN, a robot that helps people with mild cognitive impairment
(via sciencedaily.com) Original source Meet CARMEN, short for Cognitively Assistive Robot for Motivation and Neurorehabilitation -- a small, tabletop robot designed to help people with mild cognitive impairment (MCI) learn skills to improve memory, attention, and executive functioning at home.
Published Prying open the AI black box
(via sciencedaily.com) Original source Meet SQUID, a new computational tool. Compared with other genomic AI models, SQUID is more consistent, reduces background noise, and can yield better predictions regarding critical mutations. The new system aims to bring scientists closer to their findings' true medical implications.
Published Much of the Nord Stream gas remained in the sea
(via sciencedaily.com) Original source Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.
Published Restored rat-free islands could support hundreds of thousands more breeding seabirds
(via sciencedaily.com) Original source Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.
Published Researchers teach AI to spot what you're sketching
(via sciencedaily.com) Original source A new way to teach artificial intelligence (AI) to understand human line drawings -- even from non-artists -- has been developed.
Published AI recognizes athletes' emotions
(via sciencedaily.com) Original source Using computer-assisted neural networks, researchers have been able to accurately identify affective states from the body language of tennis players during games. For the first time, they trained a model based on artificial intelligence (AI) with data from actual games. Their study demonstrates that AI can assess body language and emotions with accuracy similar to that of humans. However, it also points to ethical concerns.
Published Satellites to monitor marine debris from space
(via sciencedaily.com) Original source Detecting marine debris from space is now a reality, according to a new study. Until now, the amount of litter -- mostly plastic -- on the sea surface was rarely high enough to generate a detectable signal from space. However, using supercomputers and advanced search algorithms, the research team has demonstrated that satellites are an effective tool for estimating the amount of litter in the sea.
Published Researchers use large language models to help robots navigate
(via sciencedaily.com) Original source A technique can plan a trajectory for a robot using only language-based inputs. While it can't outperform vision-based approaches, it could be useful in settings that lack visual data to use for training.
Published Self-assembling and disassembling swarm molecular robots via DNA molecular controller
(via sciencedaily.com) Original source Researchers have succeeded in developing a DNA-based molecular controller. Crucially, this controller enables the autonomous assembly and disassembly of molecular robots, as opposed to manually directing it.
Published A conservation market could incentivize global ocean protection
(via sciencedaily.com) Original source Thirty-by-thirty: protect 30% of the planet by 2030. While conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Researchers have now proposed a market-based approach to achieving the 30x30 targets in the ocean.
Published Scientists unravel drivers of the global zinc cycle in our oceans, with implications for a changing climate
(via sciencedaily.com) Original source The understanding of the global zinc cycle in our oceans has important implications in the context of warming oceans. A warmer climate increases erosion, leading to more dust in the atmosphere and consequently more dust being deposited into the oceans. More dust means more scavenging of zinc particles, leading to less zinc being available to sustain phytoplankton and other marine life, thereby diminishing the oceans' ability to absorb carbon.
