Published Protected areas in Thailand are at a higher risk of forest fires when located away from indigenous communities
(via sciencedaily.com) Original source Research has found that national parks and protected areas are at a higher risk of forest fires when located farther away from indigenous communities. Based on the analysis of satellite images from Thailand and case studies from other Southeast Asian countries, the research demonstrates that policymakers can achieve improvements in forest health by working collaboratively with indigenous communities. Involving communities results in reduction of forest fires and air pollution.
Published Climate change shown to cause methane to be released from the deep ocean
(via sciencedaily.com) Original source New research has shown that fire-ice -- frozen methane which is trapped as a solid under our oceans -- is vulnerable to melting due to climate change and could be released into the sea.
Published Greenhouse gases in oceans are altered by climate change impact on microbes
(via sciencedaily.com) Original source The ocean is a global life-support system, and climate change causes such as ocean warming, acidification, deoxygenation, and nitrogen-deposition alter the delicate microbial population in oceans. The marine microbial community plays an important role in the production of greenhouse gases like nitrous oxide and methane. Scientists have explored the climate change impact on marine microbes. Their research helps raise awareness about climate change severity and the importance of ocean resources.
Published The ocean may be storing more carbon than estimated in earlier studies
(via sciencedaily.com) Original source The ocean's capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report. Scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed. Plankton gobble up carbon dioxide and, as they grow, convert it into organic tissue via photosynthesis.
Published Plant nurseries are exacerbating the climate-driven spread of 80% of invasive species
(via sciencedaily.com) Original source Researchers have provided detailed maps of how 144 common invasive plants species will react to 2° Celsius of climate change in the eastern U.S., as well as the role that garden centers currently play in seeding future invasions.
Published Artificial intelligence makes gripping more intuitive
(via sciencedaily.com) Original source Artificial hands can be operated via app or with sensors placed in the muscles of the forearm. New research shows: a better understanding of muscle activity patterns in the forearm supports a more intuitive and natural control of artificial limbs. This requires a network of 128 sensors and artificial intelligence based techniques.
Published Exposure to soft robots decreases human fears about working with them
(via sciencedaily.com) Original source Seeing robots made with soft, flexible parts in action appears to lower people's anxiety about working with them or even being replaced by them. A study found that watching videos of a soft robot working with a person at picking and placing tasks lowered the viewers' safety concerns and feelings of job insecurity. This was true even when the soft robot was shown working in close proximity to the person. This finding shows soft robots hold a potential psychological advantage over rigid robots made of metal or other hard materials.
Published Underwater vehicle AI model could be used in other adaptive control systems
(via sciencedaily.com) Original source Unmanned Underwater Vehicles (UUVs) are used around the world to conduct difficult environmental, remote, oceanic, defense and rescue missions in often unpredictable and harsh conditions. A new study has now used a novel bio-inspired computing artificial intelligence solution to improve the potential of UUVs and other adaptive control systems to operate more reliability in rough seas and other unpredictable conditions.
Published Fossil CO2 emissions at record high in 2023
(via sciencedaily.com) Original source Global carbon emissions from fossil fuels have risen again in 2023 -- reaching record levels, according to new research.
Published Deep sea sensor reveals that corals produce reactive oxygen species
(via sciencedaily.com) Original source A new sensor on the submersible Alvin discovered reactive oxygen species for the first time in deep-sea corals, broadening our understanding of fundamental coral physiology.
Published How mountains affect El Niño-induced winter precipitation
(via sciencedaily.com) Original source A consideration of how mountains influence El Niño and La Niña-induced precipitation change in western North America may be the ticket to more informed water conservation planning along the Colorado River, new research suggests.
Published Snail-inspired robot could scoop ocean microplastics
(via sciencedaily.com) Original source Inspired by a small and slow snail, scientists have developed a robot protype that may one day scoop up microplastics from the surfaces of oceans, seas and lakes.
Published Artificial light is luring birds to cities and sometimes to their deaths
(via sciencedaily.com) Original source Scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap -- with buildings that lead to collisions, less habitat, scarcer food, and more people and cats. The study provides the first continent-wide maps of migration stopover hotspots in the contiguous United States, and knowing these broadscale layover patterns can help in the development of conservation plans.
Published A color-based sensor to emulate skin's sensitivity
(via sciencedaily.com) Original source In a step toward more autonomous soft robots and wearable technologies, researchers have created a device that uses color to simultaneously sense multiple mechanical and temperature stimuli.
Published Consensus needed on when global warming reaches 1.5°C
(via sciencedaily.com) Original source A team of scientists has emphasized that -- surprisingly -- there is currently no formally agreed way of defining the current level of global warming relevant to the Paris Agreement.
Published Illuminating the benefits of marine protected areas for ecotourism, and vice versa
(via sciencedaily.com) Original source As California, the U.S. and the world work to make good on commitments to conserve 30% of oceans and lands by 2030, all strategies are on the table -- and under the microscope. When it comes to the ocean, one valuable tool is marine protected areas (MPAs), regions that are defined, designated and managed for long-term conservation. Among other benefits, MPAs protect habitats and promote species diversity. They also hold value for communities and industries.
Published Antarctica's ancient ice sheets foreshadow dynamic changes in Earth's future
(via sciencedaily.com) Original source Identifying how and why Antarctica's major ice sheets behaved the way they did in the early Miocene could help inform understanding of the sheets' behavior under a warming climate. Together, the ice sheets lock a volume of water equivalent to more than 50 meters of sea level rise and influence ocean currents that affect marine food webs and regional climates. Their fate has profound consequences for life nearly everywhere on Earth.
Published Researchers develop novel deep learning-based detection system for autonomous vehicles
(via sciencedaily.com) Original source Autonomous vehicles require object detection systems to navigate traffic and avoid obstacles on the road. However, current detection methods often suffer from diminished detection capabilities due to bad weather, unstructured roads, or occlusion. Now, a team of researchers has developed a novel Internet-of-Things-enabled deep learning-based end-to-end 3D object detection system with improved detection capabilities even under unfavorable conditions. This study marks a significant step in autonomous vehicle object detection technology.
Published Decoding past climates through dripstones
(via sciencedaily.com) Original source A recent study demonstrates how dripstones can be crucial for reconstructing past climates. The new approach can provide a detailed picture of the climate around early human occupations in South Africa.
