Published An 'introspective' AI finds diversity improves performance
(via sciencedaily.com) Original source An artificial intelligence with the ability to look inward and fine tune its own neural network performs better when it chooses diversity over lack of diversity, a new study finds. The resulting diverse neural networks were particularly effective at solving complex tasks.
Published New AI technology gives robot recognition skills a big lift
(via sciencedaily.com) The day when robots can cook dinner, clear the kitchen table and empty the dishwasher is still a long way off. First, robots need to be able to recognize the many items of different sizes, shapes and brands in our homes. A team has now made a significant advance toward that technology with a robotic system that uses artificial intelligence to help robots better identify and remember objects.
Published Arctic soil methane consumption may be larger than previously thought and increases in a drier climate
(via sciencedaily.com) Original source A recent study finds that Arctic soil methane uptake may be larger than previously thought, and that methane uptake increases under dry conditions and with availability of labile carbon substrates.
Published Coastal fisheries show surprising resilience to marine heat waves
(via sciencedaily.com) New research found that marine heat waves -- prolonged periods of unusually warm ocean temperatures -- haven't had a lasting effect on the fish communities that feed most of the world. The finding is in stark contrast to the devastating effects seen on other marine ecosystems cataloged by scientists after similar periods of warming, including widespread coral bleaching and harmful algal blooms.
Published Using evidence from last Ice Age, scientists predict effects of rising seas on coastal habitats
(via sciencedaily.com) Original source The rapid sea level rise and resulting retreat of coastal habitat seen at the end of the last Ice Age could repeat itself if global average temperatures rise beyond certain levels, according to an analysis by an international team of scientists.
Published Emphasizing the need for energy independence could change the views of climate deniers, study says
(via sciencedaily.com) Original source Emphasising the need for energy independence and environmental stewardship could help to change people’s minds about the climate crisis, a new study says.
Published Can this forest survive? Predicting forest death or recovery after drought
(via sciencedaily.com) Original source New work could help forest managers predict which forests are most at risk from drought and which will survive.
Published Tiny, shape-shifting robot can squish itself into tight spaces
(via sciencedaily.com) Imagine a robot that can wedge itself through the cracks in rubble to search for survivors trapped in the wreckage of a collapsed building. Engineers are working toward to that goal with CLARI, short for Compliant Legged Articulated Robotic Insect.
Published After Chernobyl nuclear accident: The wild boar paradox, finally solved
(via sciencedaily.com) Original source While the contamination of deer and roe deer decreased over time as expected, the measured levels of radioactivity in the meat of wild boar remained surprisingly high -- higher than the half-life of cesium would suggest. For many years, this 'wild boar paradox' was considered unsolved. Now an explanation has been found: It is a late aftermath of the nuclear weapons tests from the 1960s.
Published Want to fight climate change? Don't poach gorillas (or elephants, hornbills, toucans, etc.)
(via sciencedaily.com) Original source A new article found that overhunting of gorillas, elephants, and other large fruit-eating seed-dispersers make tropical forests less able to store or sequester carbon.
Published Sensors harnessing light give hope in rehabilitation
(via sciencedaily.com) A research team overcomes limitations of conventional strain sensors using computer vision integrated optical sensors.
Published Wildfire, soil emissions increasing air pollution in remote forests
(via sciencedaily.com) Original source Nitrogen dioxide levels in remote forest areas are increasing, and wildfire and soil emissions are likely the reasons why, finds a new study.
Published Broken by bison, aspen saplings having a tough time in northern Yellowstone
(via sciencedaily.com) In northern Yellowstone National Park, saplings of quaking aspen, an ecologically important tree in the American West, are being broken by a historically large bison herd, affecting the comeback of aspen from decades of over-browsing by elk.
Published Past abrupt changes in North Atlantic Overturning have impacted the climate system across the globe
(via sciencedaily.com) Original source Abrupt climate changes have affected rainfall patterns worldwide in the past, especially in the tropical monsoon region, a new study shows. An international team of scientists used dripstones from globally distributed caves together with model simulations to analyze the global impacts of rapid Northern-Hemisphere temperature increases, the widely studied Dansgaard-Oeschger events, that repeatedly occurred during the last ice age. The comparison of stalagmite and model data shows in unprecedented detail how these abrupt changes and the associated modifications of the Atlantic overturning circulation, AMOC for short, have affected global atmospheric circulation.
Published Due to sea-ice retreat, zooplankton could remain in the deep longer
(via sciencedaily.com) Original source Due to intensifying sea-ice melting in the Arctic, sunlight is now penetrating deeper and deeper into the ocean. Since marine zooplankton respond to the available light, this is also changing their behavior -- especially how the tiny organisms rise and fall within the water column. As an international team of researchers has now shown, in the future this could lead to more frequent food shortages for the zooplankton, and to negative effects for larger species including seals and whales.
Published Brain signals transformed into speech through implants and AI
(via sciencedaily.com) Researchers have succeeded in transforming brain signals into audible speech. By decoding signals from the brain through a combination of implants and AI, they were able to predict the words people wanted to say with an accuracy of 92 to 100%.
Published Researcher finds inspiration from spider webs and beetles to harvest fresh water from thin air
(via sciencedaily.com) A team of researchers is designing novel systems to capture water vapor in the air and turn it into liquid. They have developed sponges or membranes with a large surface area that continually capture moisture from their surrounding environment.
Published Pros and cons of ChatGPT plugin, Code Interpreter, in education, biology, health
(via sciencedaily.com) Researchers see potential in educational settings for the newest official ChatGPT plugin, called Code Interpreter, they've found limitations for its use by scientists who work with biological data utilizing computational methods to prioritize targeted treatment for cancer and genetic disorders.
Published Soils forming on the branches of trees are an overlooked forest habitat
(via sciencedaily.com) A study on 'canopy soils' on old trees in Costa Rica shows they are important habitats and carbon stores that cannot easily be replaced.
Published AI helps robots manipulate objects with their whole bodies
(via sciencedaily.com) A new AI technique enables a robot to develop complex plans for manipulating an object using its entire hand, not just fingertips. This model can generate effective plans in about a minute using a standard laptop.
