Crawfish could transfer ionic lithium from their environment into food chain
From cell phones to watches to electric cars, lithium-ion rechargeable batteries power a plethora of devices. The increased use of this technology means more lithium could find its way into the environment as consumers discard electronic products......»»
Researchers explore how beluga whale melon changes shape during social interaction
A trio of animal science researchers at the University of Rhode Island, in the U.S., has identified five major shapes displayed by the beluga whale melon. For their study published in the journal Animal Cognition, Justin Richard, Isabelle Pellegrini,.....»»
Hitting this stretchy, electronic material makes it tougher
Accidents happen every day, and if you drop your smartwatch, or it gets hit really hard, the device probably won't work anymore. But now, researchers report on a soft, flexible material with "adaptive durability," meaning it gets stronger when hit or.....»»
Electronic perturbation-promoted interfacial pathway for facile C–H dissociation
Pt-based catalysts have been extensively employed in catalytic propane dehydrogenation (PDH) processes, playing a crucial role in propylene production. However, monometallic Pt catalysts often exhibit inferior propylene selectivity due to the hydroge.....»»
Tanks of the triassic: New crocodile ancestor identified
Dinosaurs get all the glory. But aetosaurs, a heavily armored cousin of modern crocodiles, ruled the world before dinosaurs did. These tanks of the Triassic came in a variety of shapes and sizes before going extinct around 200 million years ago. Toda.....»»
Arctic cooperation at a standstill because of Russia"s war in Ukraine: Report
A new ZOiS Report analyzes the various effects of Russia's war against Ukraine on the Arctic region. The authors also assess how a baseline of coordination with Russia on the vital issues of security and climate change could be re-established for the.....»»
Revealing environmental exposure to liquid crystal monomers from digital displays
Liquid crystal monomers (LCMs) are synthetic organic chemicals used in manufacturing liquid crystal displays (LCDs) present in numerous digital electronic devices. As the use of digital electronics, such as computers and smartphones, becomes increasi.....»»
Conduction of catalytic properties from buried transitional metals to exposed inert main group metals
The electronic interaction between buried single transitional metal and adjacent aluminum atoms via metallic bonding can be well demonstrated......»»
Hubble tracks Jupiter"s stormy weather
The largest and nearest of the giant outer planets, Jupiter's colorful clouds present an ever-changing kaleidoscope of shapes and colors. This is a planet where there is always stormy weather: cyclones, anticyclones, wind shear, and the largest storm.....»»
Quantum dance to the beat of a drum: Researchers observe how energy of single electron is tuned by surrounding atoms
Physicists at the University of Regensburg have choreographed the shift of a quantized electronic energy level with atomic oscillations faster than a trillionth of a second......»»
"Post Office Horizon" scandal exposes dangers of "technological justice", according to study
A new study examines how the Post Office Horizon scandal exposes the dangers of 'technological justice'. Researchers also emphasize the dangers of 'technological rationality', where technology shapes not only our actions but also our capacity for cri.....»»
Scientists use spent brewer"s yeast to filter out metal from waste streams
When we recycle electronic devices we can no longer use, we expect to make the most out of the precious natural resources that went into building them. But electronic waste is notoriously difficult to recycle because it's hard to separate the differe.....»»
Coalition launches to expand electronic vehicle title and registration process
The eSTART — or Electronic Secure Title and Registration Transformation — Coalition, which will launch Wednesday, wants to bring awareness to legislative efforts, facilitate engagement and dispel misconceptions associated with electronic title an.....»»
Researchers devise new ways to engineer carbon-based semiconductors for electronics of the future
It might look like a roll of chicken wire, but this tiny cylinder of carbon atoms—too small to see with the naked eye—could one day be used for making electronic devices ranging from night vision goggles and motion detectors to more efficient sol.....»»
Quantum-mechanical "molecules" spotted in superconducting devices
Electronic states that resemble molecules and are promising for use in future quantum computers have been created in superconducting circuits by physicists at RIKEN......»»
The first Europeans reached Ukraine 1.4 million years ago, new study finds
During warm periods in Earth's history, known as interglacials, glaciers the size of continents pulled back to reveal new landscapes. These were new worlds for early humans to explore and exploit, and 1.4 million years ago this was Europe: a Terra nu.....»»
Climate change in Greenland could cause trouble for Arctic char
Arctic char (Salvelinus alpinus) like clean, cold water and can be found around northern Greenland, Svalbard, Alaska and in Arctic parts of Russia and Canada......»»
