Published A breakthrough in inexpensive, clean, fast-charging batteries
(via sciencedaily.com) Original source Scientists have created an anode-free sodium solid-state battery. This brings the reality of inexpensive, fast-charging, high-capacity batteries for electric vehicles and grid storage closer than ever.
Published Mighty floods of the Nile River during warmer and wetter climates
(via sciencedaily.com) Original source Global warming as well as recent droughts and floods threaten large populations along the Nile Valley. Sediment cores off the Nile mouth reveal insights into the effects and causes of heavy rainfall episodes about 9,000 years ago. That will help to prepare for weather extremes in a changing climate.
Published Clever clothes! Seams in clothing capture body movement
(via sciencedaily.com) Original source Everyday clothing may soon be able to capture and record body movements according to new research.
Published What was behind the 2021-2022 energy crisis within Europe?
(via sciencedaily.com) Original source A team of researchers had already been working with electricity price data for years before Russia's invasion of Ukraine, exploring statistics and developing forecasting methods. Now they zero in on how prices in different countries relate and how countries were affected by the energy crisis and address the interdependencies of different markets. Their approach combines statistical physics and network science, identifying communities and the fundamental spatiotemporal patterns within the electricity price/time data from all countries. The researchers hope their work will strengthen the European perspective in the political debate about electricity markets and prices, because problems like this are best tackled via international cooperation.
Published The evidence is mounting: humans were responsible for the extinction of large mammals
(via sciencedaily.com) Original source Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.
Published Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard
(via sciencedaily.com) Original source Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.
Published Soft, stretchy electrode simulates touch sensations using electrical signals
(via sciencedaily.com) Original source A team of researchers has developed a soft, stretchy electronic device capable of simulating the feeling of pressure or vibration when worn on the skin. This device represents a step towards creating haptic technologies that can reproduce a more varied and realistic range of touch sensations for applications such as virtual reality, medical prosthetics and wearable technology.
Published Characterization of the extraordinary thermoelectric properties of cadmium arsenide thin films
(via sciencedaily.com) Original source If there's one thing we humans are good at, it's producing heat. Significant amounts, and in many cases most of the energy we generate and put into our systems we lose as heat, whether it be our appliances, our transportation, our factories, even our electrical grid.
Published Ocean's loss of oxygen caused massive Jurassic extinction: Could it happen again?
(via sciencedaily.com) Original source Researchers have found a chemical clue in Italian limestone that explains a mass extinction of marine life in the Early Jurassic period, 183 million years ago. Volcanic activity pumped out CO2, warming oceans and lowering their oxygen levels. The findings may foretell the impact climate change and oxygen depletion might have on today's oceans.
Published Shocked quartz reveals evidence of historical cosmic airburst
(via sciencedaily.com) Original source Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth's atmosphere 12,800 years ago, causing a widespread climatic shift that, among other things, led to the abrupt reversal of the Earth's warming trend and into an anomalous near-glacial period called the Younger Dryas.
Published Researchers discover new flat electronic bands, paving way for advanced quantum materials
(via sciencedaily.com) Original source Scientists predict the existence of flat electronic bands at the Fermi level, a finding that could enable new forms of quantum computing and electronic devices.
Published Drivers ready to embrace wireless EV technology
(via sciencedaily.com) Original source Drivers are optimistic about 'on road' dynamic wireless charging that allows EV users to charge their batteries while driving -- but there are concerns.
Published Researchers engineer AI path to prevent power outages
(via sciencedaily.com) Original source Researchers developed an artificial intelligence (AI) model that could help electrical grids prevent power outages by automatically rerouting electricity in milliseconds. The approach is an early example of 'self-healing grid' technology, which uses AI to detect and repair problems such as outages autonomously and without human intervention when issues occur, such as storm-damaged power lines.
Published Carbon dioxide's heavy stamp on temperature: Doubling CO2 may mean 7 to 14 degree increase
(via sciencedaily.com) Original source A doubling of the amount of CO2 in the atmosphere could cause an increase in the average temperature on earth from 7 to even a maximum of 14 degrees. That is shown in the analysis of sediments from the Pacific Ocean off the coast of California.
Published Novel blood-powered chip offers real-time health monitoring
(via sciencedaily.com) Original source Researchers develop the first-ever device powered by blood to measure blood electrical conductivity.
Published Promise green hydrogen may not always be fulfilled
(via sciencedaily.com) Original source Green hydrogen often, but certainly not always, leads to CO2 gains.
Published The rotation of Earth's inner core has slowed, new study confirms
(via sciencedaily.com) Original source The new study provides unambiguous evidence that the inner core began to decrease its speed around 2010, moving slower than the Earth's surface.
Published New dart launcher may be better way to inject animals with drugs
(via sciencedaily.com) Original source A new type of dart launcher has been developed as a safer and more cost-effective alternative to firearms or air guns to inject animals with drugs or tracking chips.
Published Ancient ocean slowdown warns of future climate chaos
(via sciencedaily.com) Original source When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.
Published A 'liquid battery' advance
(via sciencedaily.com) Original source A team aims to improve options for renewable energy storage through work on an emerging technology -- liquids for hydrogen storage.
