Published Geologists challenge conventional view of Earth's continental history, stability with new study
(via sciencedaily.com) Original source The seemingly stable regions of the Earth's continental plates -- the so-called stable cratons -- have suffered repetitive deformation below their crust since their formation in the remote past, according to new research from the University of Illinois Urbana-Champaign. This hypothesis defies decades of conventional plate tectonics theory and begs to answer why most cratons have remained structurally stable while their underbellies have experienced significant change.
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 MethaneMapper is poised to solve the problem of underreported methane emissions
(via sciencedaily.com) Original source MethaneMapper is an artificial intelligence-powered hyperspectral imaging tool that researchers have developed to detect real-time methane emissions and trace them to their sources. The tool works by processing hyperspectral data gathered during overhead, airborne scans of the target area.
Published When water temperatures change, the molecular motors of cephalopods do too
(via sciencedaily.com) Original source Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.
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 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 New superconducting diode could improve performance of quantum computers and artificial intelligence
(via sciencedaily.com) Original source A team has developed a more energy-efficient, tunable superconducting diode -- a promising component for future electronic devices -- that could help scale up quantum computers for industry and improve artificial intelligence systems.
Published Viruses hidden in coral symbiont's genetic material are a potential threat to reefs
(via sciencedaily.com) Original source Microscopic algae that corals need for survival harbor a common and possibly disease-causing virus in their genetic material.
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 Shining a light on neuromorphic computing
(via sciencedaily.com) Original source AI, machine learning, and ChatGPT may be relatively new buzzwords in the public domain, but developing a computer that functions like the human brain and nervous system -- both hardware and software combined -- has been a decades-long challenge. Engineers are exploring how optical "memristors" may be a key to developing neuromorphic computing.
Published Quantum computers are better at guessing, new study demonstrates
(via sciencedaily.com) Original source Researchers have demonstrated a quantum speedup over the most efficient classical computer algorithm possible for what is believed to be the first time. The accomplishment was performed on an IBM Montreal Quantum Falcon r4 27-qubit device.
Published CRISPR/Cas9 reveals a key gene involved in the evolution of coral skeleton formation
(via sciencedaily.com) Original source New work uses cutting-edge CRISPR/Cas9 genome editing tools to reveal a gene that's critical to stony corals' ability to build their reef architectures. This research could inform coral conservation and restoration efforts.
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 New method improves efficiency of 'vision transformer' AI systems
(via sciencedaily.com) Original source Vision transformers (ViTs) are powerful artificial intelligence (AI) technologies that can identify or categorize objects in images -- however, there are significant challenges related to both computing power requirements and decision-making transparency. Researchers have now developed a new methodology that addresses both challenges, while also improving the ViT's ability to identify, classify and segment objects in images.
Published Phenomenal phytoplankton: Scientists uncover cellular process behind oxygen production
(via sciencedaily.com) Original source According to new research, the amount of oxygen in one of 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes photosynthesis in marine phytoplankton. The new study identifies how a proton pumping enzyme (known as VHA) aids in global oxygen production and carbon fixation from phytoplankton.
Published Protecting large ocean areas doesn't curb fishing catches
(via sciencedaily.com) Original source In the first-ever 'before and after' assessment of the impact of establishing Mexico's Revillagigedo National Park on the fishing industry, a team of US and Mexican researchers found that Mexico's industrial fishing sector did not incur economic losses five years after the park's creation despite a full ban in fishing activity within the MPA.
Published Ground beneath Thwaites Glacier mapped
(via sciencedaily.com) Original source The ground beneath Antarctica's most vulnerable glacier has now been mapped, helping scientists to better understand how it is being affected by climate change. Analysis of the geology below the Thwaites Glacier in West Antarctica shows there is less sedimentary rock than expected -- a finding that could affect how the ice slides and melts in the coming decades.
