Published Pairing crypto mining with green hydrogen offers clean energy boost
(via sciencedaily.com) Original source Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
Published New all-liquid iron flow battery for grid energy storage
(via sciencedaily.com) Original source A new iron-based aqueous flow battery shows promise for grid energy storage applications.
Published Unintended consequences of fire suppression
(via sciencedaily.com) Original source A new study reveals how fire suppression ensures that wildfires will burn under extreme conditions at high severity, exacerbating the impacts of climate change and fuel accumulation.
Published Researchers take major step toward developing next-generation solar cells
(via sciencedaily.com) Original source Engineers have discovered a new way to manufacture solar cells using perovskite semiconductors. It could lead to lower-cost, more efficient systems for powering homes, cars, boats and drones.
Published A new way to quantify climate change impacts: 'Outdoor days'
(via sciencedaily.com) Original source 'Outdoor days,' a new measure, describes climate change impacts by noting the number of days per year that outdoor temperatures are comfortable enough for normal outdoor activities.
Published Satellite data assimilation improves forecasts of severe weather
(via sciencedaily.com) Original source In 2020, a line of severe thunderstorms unleashed powerful winds that caused billions in damages across the Midwest United States. A new technique that incorporates satellite data could improve forecasts -- including where the most powerful winds will occur -- for similar severe weather events.
Published The heat index -- how hot it really feels -- is rising faster than temperature
(via sciencedaily.com) Original source Researchers showed in 2022 that heat index calculations by NOAA based on analyses from the 1970s don't adequately reflect the heat stress humans feel during the extremes of heat and humidity accompanying climate change. Using their revised heat index, the researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days.
Published Metamaterials and AI converge, igniting innovative breakthroughs
(via sciencedaily.com) Original source Scientists unveil next-generation research trends in metaphotonics platforms with AI.
Published Brain-inspired wireless system to gather data from salt-sized sensors
(via sciencedaily.com) Original source In a new study, researchers describe a novel approach for a wireless communication network that can efficiently transmit, receive and decode data from thousands of microelectronic chips that are each no larger than a grain of salt.
Published Fast-charging lithium-sulphur batteries on the horizon
(via sciencedaily.com) Original source New research shows that the next generation of lithium-sulphur (Li||S) batteries may be capable of being charged in less than five minutes, instead of several hours as is currently the case.
Published Self-heating concrete is one step closer to putting snow shovels and salt out of business
(via sciencedaily.com) Original source Researchers recently reported on the science behind its special concrete, that can warm itself up when it snows, or as temperatures approach freezing.
Published Meteorology: Weak polar vortex makes weather more predictable
(via sciencedaily.com) Original source Events in the stratosphere are making long-range weather in Northern Europe easier to forecast, researchers have discovered.
Published Breakthrough could make automated dosing systems universal
(via sciencedaily.com) Original source Automated insulin dosing systems combine low-cost blood-glucose monitors with insulin pumps that use precision dosing to continuously regulate blood-sugar and hold it steady. Synthetic biologists have found a way to piggyback on the technology and make it universally applicable for the precision dosing of virtually any drug.
Published Diverse habitats help salmon weather unpredictable climate changes
(via sciencedaily.com) Original source Restored salmon habitat should resemble financial portfolios, offering fish diverse options for feeding and survival so that they can weather various conditions as the climate changes, a new study shows.
Published Researchers prove fundamental limits of electromagnetic energy absorption
(via sciencedaily.com) Original source Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers optimize devices designed to block certain frequencies of radiation while allowing others to pass through, for applications such as stealth or wireless communications.
Published New study shows analog computing can solve complex equations and use far less energy
(via sciencedaily.com) Original source A team of engineers has proven that their analog computing device, called a memristor, can complete complex, scientific computing tasks while bypassing the limitations of digital computing.
Published Tropical birds could tolerate warming better than expected, study suggests
(via sciencedaily.com) Original source We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine.
Published An electricity generator inspired by the drinking bird toy powers electronics with evaporated water
(via sciencedaily.com) Original source Inspired by the classic drinking bird toy, scientists have developed an engine that efficiently converts energy from water evaporation into electricity to power small electronics. The device produces energy outputs exceeding 100 volts -- much higher than other techniques that generate electricity from water -- and can operate for several days using only 100 milliliters of water as fuel, according to a new study.
Published Ready for the storm: Researchers analyze infrastructure, demographics to see where tornadoes are most disruptive
(via sciencedaily.com) Original source Researchers examined demographics, infrastructure and more than seven decades of weather data to determine which places in Kentucky are most vulnerable to tornadoes.
Published Scientists use novel technique to create new energy-efficient microelectronic device
(via sciencedaily.com) Original source Researchers have created a new material that uses 'redox gating' to control the movement of electrons in and out of a semiconducting material.
