Published A novel, completely solid, rechargeable air battery



Solid-state batteries use solid electrodes and solid electrolytes, unlike the more commonly known lithium-ion batteries, which use liquid electrolytes. Solid-state batteries overcome various challenges associated with liquid-based batteries, such as flammability, limited voltage, unstable reactants, and poor long-term cyclability and strength. Making advances in this field, researchers recently demonstrated an all-solid-state rechargeable air battery composed of a redox-active organic negative electrode and a proton-conductive polymer electrolyte.
Published Megawatt electrical motor designed by engineers could help electrify aviation



Aerospace engineers designed a 1-megawatt electrical motor that is a stepping stone toward electrifying the largest aircraft.
Published New study could help unlock 'game-changing' batteries for electric vehicles and aviation



Researchers have revealed the mechanisms that cause lithium metal solid-state batteries to fail. The new insights could help overcome the technical issues with solid-state batteries, unlocking a game-changing technology for electric vehicles and aviation.
Published Weather anomalies are keeping insects active longer



Extreme weather events have affected moth and butterfly activity more than the average increase in global temperature over the last several decades.
Published Ticks prove resilient to extreme temperatures



A recent study shows blacklegged ticks (Ixodes scapularis) are actually really good at surviving extreme cold and heat in nature. Previous lab research suggests that even short periods of especially warm or cold conditions should easily kill ticks, but the a new analysis reveals this is only the case for larval ticks in the environment.
Published Global flash droughts expected to increase in a warming climate



Researchers have published new findings on how our warming climate will affect the frequency of flash droughts and the risk to croplands globally.
Published New method predicts extreme events more accurately



A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.
Published Simultaneous atmospheric and marine observations directly beneath a violent, Category 5 typhoon in the North-West Pacific



Scientists have successfully conducted a simultaneous marine and atmospheric measurements at multiple locations directly beneath a violent, Category 5, which is the strongest class, typhoon in the North-West Pacific, before it reached land.
Published Calcium rechargeable battery with long cycle life



With the use of electric vehicles and grid-scale energy storage systems on the rise, the need to explore alternatives to lithium-ion batteries has never been greater. Researchers have recently developed a prototype calcium metal rechargeable battery capable of 500 cycles of repeated charge-discharge -- the benchmark for practical use. The breakthrough was made thanks to the development of a copper sulfide nanoparticle/carbon composite cathode and a hydride-based electrolyte.
Published Flexing crystalline structures provide path to a solid energy future



Researchers have uncovered the atomic mechanisms that make a class of compounds called argyrodites attractive candidates for both solid-state battery electrolytes and thermoelectric energy converters. The discoveries -- and the machine learning approach used to make them -- could help usher in a new era of energy storage for applications such as household battery walls and fast-charging electric vehicles.
Published Modular builds may help construction industry weather a perfect storm



Engineers have calculated the potential cost savings for builders who opt for modular construction techniques to avoid lengthy and expensive holdups caused by poor weather.
Published How a drought affects trees depends on what's been holding them back



Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.
Published Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world



Researchers found that the Hunga-Tonga eruption was associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based communications. Their findings also suggest that a long-held atmospheric model should be revised.
Published In years after El Niño, global economy loses trillions



Researchers report that the financial toll of the climate pattern known as El Niño can persist for several years and cost trillions in lost income worldwide. The study, which is among the first to evaluate the long-term costs of El Niño, found that the 1982 and 1997 events led to $4.1 trillion and $5.7 trillion in lost income in the five years following them. With El Niño projected to return this year, the researchers project that global economic losses for the 21st century will amount to $84 trillion as climate change potentially amplifies the events' frequency and strength.
Published An electric vehicle battery for all seasons



Scientists have developed a fluorine-containing electrolyte for lithium-ion batteries whose charging performance remains high in frigid regions and seasons. They also determined why it is so effective.
Published Extremely hot days are warming twice as fast as average summer days in North-West Europe



New study analyzed data on near-surface air temperatures recorded for North-West Europe over the past 60 years. The findings show that the maximum temperature of the hottest days is increasing at twice the rate of the maximum temperature of average summer days. The results highlight the need for urgent action by policy makers to adapt essential infrastructure to the impacts of climate change.
Published New priming method improves battery life, efficiency



Engineers have developed a readily scalable method to optimize a silicon anode priming method that increases lithium-ion battery performance by 22% to 44%.
Published Extending the life of a lithium metal anode using a protective layer made of an extremely tough gel electrolyte



A research team has succeeded in substantially improving the cycling performance of a lithium metal battery by developing a mechanically very strong polymeric gel electrolyte and integrating it into the battery as a layer to protect the lithium metal anode. This achievement may greatly facilitate efforts to put lithium metal anodes -- a potentially very high performance anode material -- into practical use.
Published Atmospheric research provides clear evidence of human-caused climate change signal associated with CO2 increases



New research provides clear evidence of a human 'fingerprint' on climate change and shows that specific signals from human activities have altered the temperature structure of Earth's atmosphere.
Published Prolonged power outages, often caused by weather events, hit some parts of the U.S. harder than others



New research found that Americans already bearing the brunt of climate change and health inequities are most at risk of impact by a lengthy power outage.
