Published 'Inkable' nanomaterial promises big benefits for bendable electronics
(via sciencedaily.com) An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight and bendable displays and devices.
Published 3D-printed revolving devices can sense how they are moving
(via sciencedaily.com) Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ability to sense their angular position, rotation speed, and direction of rotation.
Published Activity deep in Earth affects the global magnetic field
(via sciencedaily.com) Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth's core, where temperatures exceed 5,000-degrees C. New research from geophysicists suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities -- or anomalies, as scientists call them -- of the Earth's magnetic field.
Published Resilient bug-sized robots keep flying even after wing damage
(via sciencedaily.com) Researchers have developed resilient artificial muscles that can enable insect-scale aerial robots to effectively recover flight performance after suffering severe damage.
Published Where did Earth's water come from? Not melted meteorites, according to scientists
(via sciencedaily.com) A new study brings scientists one step closer to answering the question of where Earth's water came from.
Published Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots
(via sciencedaily.com) The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.

Published The world's atmospheric rivers now have an intensity ranking like hurricanes
(via sciencedaily.com) Atmospheric rivers, which are long, narrow bands of water vapor, are becoming more intense and frequent with climate change. A new study demonstrates that a recently developed scale for atmospheric river intensity (akin to the hurricane scale) can be used to rank atmospheric rivers and identify hotspots of the most intense atmospheric rivers not only along the U.S. West Coast but also worldwide.
Published Life in the smoke of underwater volcanoes
(via sciencedaily.com) Disconnected from the energy of the sun, the permanently ice-covered Arctic deep sea receives miniscule amounts of organic matter that sustains life. Bacteria which can harvest the energy released from submarine hydrothermal sources could thus have an advantage. Scientists found bacteria uniquely adapted to this geo-energy floating in deep-sea waters. They describe the role of these bacteria for biogeochemical cycling in the ocean.
Published Virtual reality games can be used as a tool in personnel assessment
(via sciencedaily.com) Fast gamers are more intelligent: Intelligence can be predicted through virtual reality games.
Published In the world's smallest ball game, scientists throw and catch single atoms using light
(via sciencedaily.com) Researchers show that individual atoms can be caught and thrown using light. This is the first time an atom has been released from a trap -- or thrown -- and then caught by another trap. This technology could be used in quantum computing applications.
Published Researchers unveil smart contact lens, capable of implementing AR-based navigation
(via sciencedaily.com) A research team has introduced core technology for smart contact lenses that can implement AR-based navigation through a 3D printing process.
Published A pool at Yellowstone is a thumping thermometer
(via sciencedaily.com) Doublet Pool's regular thumping is more than just an interesting tourist attraction. A new study shows that the interval between episodes of thumping reflects the amount of energy heating the pool at the bottom, as well as in indication of how much heat is being lost through the surface. Doublet Pool, the authors found, is Yellowstone's thumping thermometer.
Published Viable superconducting material created, say researchers
(via sciencedaily.com) Researchers report the creation of a superconducting material at both a temperature and pressure low enough for practical applications. In a new paper, the researchers describe a nitrogen-doped lutetium hydride that exhibits superconductivity at 69 degrees Fahrenheit and 10 kilobars (145,000 pounds per square inch, or psi) of pressure.
Published Gas monitoring at volcanic fields outside Naples, Italy, exposes multiple sources of carbon dioxide emissions
(via sciencedaily.com) The Phlegraean volcanic fields just west of Naples, Italy, are among the top eight emitters of volcanic carbon dioxide in the world. Since 2005, the Solfatara crater -- one of many circular depressions in the landscape left by a long history of eruptions --has been emitting increased volumes of gas. Today it emits 4,000-5,000 tons of carbon dioxide each day, equivalent to the emissions from burning ~500,000 gallons of gasoline. Researchers estimate that as much as 20%--40% of the current carbon dioxide emissions are from the dissolution of calcite in the rocks, while 60%--80% is from underground magma.
Published New breakthrough enables perfectly secure digital communications
(via sciencedaily.com) Researchers have achieved a breakthrough to enable 'perfectly secure' hidden communications for the first time. The method uses new advances in information theory methods to conceal one piece of content inside another in a way that cannot be detected. This may have strong implications for information security, besides further applications in data compression and storage.
Published Mineral particles and their role in oxygenating the Earth's atmosphere
(via sciencedaily.com) Mineral particles played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, according to new research.
Published Can artificial intelligence help find life on Mars or icy worlds?
(via sciencedaily.com) Researchers have mapped the sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano. Then they trained a machine learning model to recognize the patterns and rules associated with their distributions so it could learn to predict and find those same distributions in data on which it was not trained. In this case, by combining statistical ecology with AI/ML, the scientists could locate and detect biosignatures up to 87.5 percent of the time and decrease the area needed for search by up to 97 percent.
Published Mississippi River Delta study reveals which human actions contribute to land loss
(via sciencedaily.com) Scientists reveal new information about the role humans have played in large-scale land loss in the Mississippi River Delta -- crucial information in determining solutions to the crisis.
Published Most detailed geological model reveals Earth's past 100 million years
(via sciencedaily.com) Previous models of Earth's recent (100 million years) geomorphology have been patchy at best. For the first time a detailed continuous model of the Earth's landscape evolution is presented, with potential for understanding long-term climate and biological development.
