Published New research sheds light on relationships between plants and insects in forest ecosystems
(via sciencedaily.com) Original source Researchers have published new findings on how leaf-eating insects affect forest ecosystems worldwide. Researchers are aware of how large herbivores cycle nutrients in forests. They know much less, however, about how leaf-eating insects impact forest carbon and nutrient cycling.
Published Scientists discover entirely new wood type that could be highly efficient at carbon storage
(via sciencedaily.com) Original source Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood.
Published Shape-shifting 'transformer bots' inspired by origami
(via sciencedaily.com) Original source Inspired by the paper-folding art of origami, engineers have discovered a way to make a single plastic cubed structure transform into more than 1,000 configurations using only three active motors.
Published Robotics: Self-powered 'bugs' can skim across water to detect environmental data
(via sciencedaily.com) Original source Researchers have developed a self-powered 'bug' that can skim across the water, and they hope it will revolutionize aquatic robotics.
Published Generative AI pioneers the future of child language learning
(via sciencedaily.com) Original source Researchers create a storybook generation system for personalized vocabulary learning.
Published The ancestor of all modern birds probably had iridescent feathers
(via sciencedaily.com) Original source Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
Published Mixed approach to reforestation better than planting or regeneration alone
(via sciencedaily.com) Original source Reforestation in low- and middle-income countries can remove up to 10 times more carbon dioxide from the atmosphere at lower cost than previously estimated, making it a potentially more effective option to fight climate change. Most current reforestation programs focus on tree planting alone, but the study estimates that nearly half of all suitable reforestation locations would be more effective at sequestering carbon if forests were allowed to grow back naturally.
Published How well does tree planting work in climate change fight? It depends
(via sciencedaily.com) Original source Using trees as a cost-effective tool against climate change is more complicated than simply planting large numbers of them, an international collaboration has shown.
Published Trees reveal climate surprise -- bark removes methane from the atmosphere
(via sciencedaily.com) Original source Tree bark surfaces play an important role in removing methane gas from the atmosphere.
Published Researchers leveraging AI to train (robotic) dogs to respond to their masters
(via sciencedaily.com) Original source An international collaboration seeks to innovate the future of how a mechanical man's best friend interacts with its owner, using a combination of AI and edge computing called edge intelligence. The overarching project goal is to make the dog come 'alive' by adapting wearable-based sensing devices that can detect physiological and emotional stimuli inherent to one's personality and traits, such as introversions, or transient states, including pain and comfort levels.
Published New video test for Parkinson's uses AI to track how the disease is progressing
(via sciencedaily.com) Original source An automated assessment technique that uses artificial intelligence could revolutionize the management of Parkinson's disease.
Published Heat-sensitive trees move uphill seeking climate change respite
(via sciencedaily.com) Original source Trees in the Brazilian Atlantic Forest are migrating in search of more favourable temperatures with species in mountain forests moving uphill to escape rising heat caused by climate change.
Published Development of 'living robots' needs regulation and public debate
(via sciencedaily.com) Original source Researchers are calling for regulation to guide the responsible and ethical development of bio-hybrid robotics -- a ground-breaking science which fuses artificial components with living tissue and cells.
Published Genome study informs restoration of American chestnut tree
(via sciencedaily.com) Original source Researchers use genomes to help restore the American chestnut population and adjust species breeding to the changing climate.
Published Can consciousness exist in a computer simulation?
(via sciencedaily.com) Original source A new essay explores which conditions must be met for consciousness to exist. At least one of them can't be found in a computer.
Published Hundreds of new genome sequences fill gaps in the fruit fly tree of life
(via sciencedaily.com) Original source A multitude of new genomic sequence data fills major gaps in the fruit fly tree of life, researchers report.
Published Ant insights lead to robot navigation breakthrough
(via sciencedaily.com) Original source Have you ever wondered how insects are able to go so far beyond their home and still find their way? The answer to this question is not only relevant to biology but also to making the AI for tiny, autonomous robots. Drone-researchers felt inspired by biological findings on how ants visually recognize their environment and combine it with counting their steps in order to get safely back home. They have used these insights to create an insect-inspired autonomous navigation strategy for tiny, lightweight robots. It allows such robots to come back home after long trajectories, while requiring extremely little computation and memory (0.65 kiloByte per 100 m). In the future, tiny autonomous robots could find a wide range of uses, from monitoring stock in warehouses to finding gas leaks in industrial sites.
Published Discovery of a hybrid lineage offers clues to how trees adapt to climate change
(via sciencedaily.com) Original source The discovery of a hybrid population of poplar trees in western Wyoming has provided insight into how natural hybridization informs the evolution of many plant species, according to researchers. They also said their discovery suggests that genetic exchange between species may be critical for adaptation to environmental change.
Published Forests endure as carbon sink despite regional pressures
(via sciencedaily.com) Original source Despite facing regional threats like deforestation and wildfires, the world's forests continue to be a powerful weapon in the fight against climate change. A new study reveals these vital ecosystems have consistently absorbed carbon dioxide for the past three decades, even as disruptions chip away at their capacity. The study, based on long-term ground measurements combined with remote sensing data, found that forests take up an average of 3.5 0.4 billion metric tons of carbon per year, which is nearly half of the carbon dioxide emissions from burning fossil fuels between 1990 and 2019.
Published Logged forests can still have ecological value -- if not pushed too far
(via sciencedaily.com) Original source Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.
