Published Hotter sand from microplastics could affect sea turtle development
(via sciencedaily.com) Original source New research has found that extreme concentrations of microplastics could increase the temperature of beach sand enough to threaten the development of incubating sea turtles.
Published Four-legged robot traverses tricky terrains thanks to improved 3D vision
(via sciencedaily.com) Original source Researchers have developed a new model that trains four-legged robots to see more clearly in 3D. The advance enabled a robot to autonomously cross challenging terrain with ease -- including stairs, rocky ground and gap-filled paths -- while clearing obstacles in its way.
Published Mori3: A polygon shape-shifting robot for space travel
(via sciencedaily.com) Original source By combining inspiration from the digital world of polygon meshing and the biological world of swarm behavior, the Mori3 robot can morph from 2D triangles into almost any 3D object. The research shows the promise of modular robotics for space travel.
Published Eddies: Circular currents and their influence on the world's hottest ocean
(via sciencedaily.com) Original source Water from the Pacific Ocean flows into the Indian Ocean via the Indonesia Archipelago thanks to a vast network of currents that act as a conveyor belt, transporting warmth and nutrients. Currents can sometimes form circular motions and these are known as eddies. An international group of researchers has modeled the impacts of eddies on the currents that carry water from the Pacific Ocean to the Indian Ocean.
Published South Africa, India and Australia shared similar volcanic activity 3.5 billion years ago
(via sciencedaily.com) Original source The Daitari greenstone belt shares a similar geologic make-up when compared to the greenstones exposed in the Barberton and Nondweni areas of South Africa and those from the Pilbara Craton of north-western Australia.
Published Aviation turbulence strengthened as the world warmed
(via sciencedaily.com) Original source New research shows that clear-air turbulence increased in various regions around the world from 1979 -- 2020.
Published Chatgpt designs a robot
(via sciencedaily.com) Original source Poems, essays and even books -- is there anything the OpenAI platform ChatGPT can't handle? These new AI developments have inspired researchers to dig a little deeper: For instance, can ChatGPT also design a robot? And is this a good thing for the design process, or are there risks?
Published Measuring greenhouse gas from ponds improves climate predictions
(via sciencedaily.com) Original source Shallow lakes and ponds emit significant amounts of greenhouse gases into the atmosphere, but emissions from these systems vary considerably and are not well understood.
Published Sponge makes robotic device a soft touch
(via sciencedaily.com) Original source A simple sponge has improved how robots grasp, scientists have found.
Published Coral disease tripled in the last 25 years. Three-quarters will likely be diseased by next century
(via sciencedaily.com) Original source Research suggests warming temperatures will see nearly 80 per cent of coral in reefs diseased in the next 80 years.
Published Whales not to be counted on as 'climate savers'
(via sciencedaily.com) Original source Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The team found the amount potentially sequestered by the whales was too minimal to make significant impact on the trajectory of climate change.
Published Robot 'chef' learns to recreate recipes from watching food videos
(via sciencedaily.com) Original source Researchers have trained a robotic 'chef' to watch and learn from cooking videos, and recreate the dish itself.
Published River diversions may cause microplastics to remain longer on land and in streams before reaching oceans
(via sciencedaily.com) Original source Diverting streams and rivers to irrigate crops or provide drinking water may significantly extend the time microplastics spend in river catchments before they flow into our oceans, a new study reveals.
Published Below the surface: Researchers uncover reasons to rethink how mountains are built
(via sciencedaily.com) Original source A study suggests that the answers to how and why mountains form are buried deeper than once thought. Clues in the landscape of southern Italy allowed researchers to produce a long-term, continuous record of rock uplift, the longest and most complete record of its kind.
Published Researchers cultivate archaea that break down crude oil in novel ways
(via sciencedaily.com) Original source The seafloor is home to around one-third of all the microorganisms on the Earth and is inhabited even at a depth of several kilometers. Only when it becomes too hot does the abundance of microorganisms appear to decline. But how, and from what, do microorganisms in the deep seafloor live? How do their metabolic cycles work and how do the individual members of these buried communities interact? Researchers have now been able to demonstrate in laboratory cultures how small, liquid components of crude oil are broken down through a new mechanism by a group of microorganisms called archaea.
Published Little-known microbes could help predict climate tipping points
(via sciencedaily.com) Original source Rising temperatures could push ocean plankton and other single-celled creatures toward a carbon tipping point that fuels more warming. The carbon-eaters could become carbon-emitters. But new research shows it's also possible to detect early distress signals before they get there.
Published Petit-spot volcanoes involve the deepest known submarine hydrothermal activity, possibly release CO2 and methane
(via sciencedaily.com) Original source Underwater volcanism and its hydrothermal activity play an important role in marine biogeochemical cycles, especially the carbon cycle. But the nature of hydrothermal activity at 'petit-spot' volcanoes have not been revealed at all. Now, scientists reveal that petit-spot hydrothermal activity occurs on the deepest seafloor known to date and could release carbon dioxide (CO2) and methane, which may have implications for the global carbon cycle.
Published Newborn baby inspires sensor design that simulates human touch
(via sciencedaily.com) Original source As we move into a world where human-machine interactions are becoming more prominent, pressure sensors that are able to analyze and simulate human touch are likely to grow in demand.
Published Thermal energy stored by land masses has increased significantly
(via sciencedaily.com) Original source There are many effects of climate change. Perhaps the most broadly known is global warming, which is caused by heat building up in various parts of the Earth system, such as the atmosphere, the ocean, the cryosphere and the land. 89 percent of this excess heat is stored in the oceans, with the rest in ice and glaciers, the atmosphere and land masses (including inland water bodies). An international research team has now studied the quantity of heat stored on land, showing the distribution of land heat among the continental ground, permafrost soils, and inland water bodies. The calculations show that more than 20 times as much heat has been stored there since the 1960s, with the largest increase being in the ground.
Published Overfishing linked to rapid evolution of codfish
(via sciencedaily.com) Original source The overfishing of codfish spanning the second half of the 20th century indicates that human action can force evolutionary changes more quickly than widely believed, according to a new study.
