Sneaker waves are likely fueled by a specific type of wave condition generated by far-off storms and paired with just the right conditions closer to shore, a new study has found.

A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.

Honey bee colony loss across the United States over the last five years is primarily related to the presence of parasitic mites, nearby pesticides, and extreme weather events as well as challenges with overwintering, according to a new study. The study took advantage of novel statistical methods and is among the first to concurrently consider a variety of potential honey bee stressors at a national scale.

A handful of hyper-productive fisheries provide sustenance to a billion people and employ tens of millions. These fisheries occur on the eastern edges of the world's oceans -- off the West Coast of the U.S., the Canary Islands, Peru, Chile, and Benguela. There, a process called upwelling brings cold water and nutrients to the surface, which in turn supports large numbers of larger sea creatures that humans depend on for sustenance. A new project is seeking to understand how changes to the climate and oceans will impact fisheries in the U.S. and around the world.

Scientists have conducted a detailed examination of high-nickel-content layered cathodes, considered to be components of promise in next-generation lithium-ion batteries. Advanced electron microscopy and deep machine learning enabled the team to observe atomic-scale changes at the interface of materials that make up the batteries.

Europe lacks groundwater -- a lot of groundwater. The continent has already been suffering from a severe drought since 2018. This is confirmed by satellite data.

Mobile phone batteries with a lifetime up to three times longer than today's technology could be a reality thanks to a recent innovation.

Scientists are drawing inspiration from plants to develop new techniques to separate and extract valuable minerals, metals and nutrients from resource-rich wastewater.

Researchers recently announced that salt marshes, critical habitats threatened by rapid sea-level rise, may in fact thrive despite higher water levels. The key factor that determines whether salt marshes collapse or flourish involves not water, but sediment.

Las Vegas, with its rapid urbanization and desert landscape, is highly vulnerable to flooding. For this reason, flood managers have built an extensive system of drainage ditches and detention basins to protect the public. Now, a new study shows how intentional engineering and urban development are interacting with climate change to alter the timing and intensity of flood risk.

Researchers have devised a better way to measure how fast sediment flows in rivers -- information that can help scientists and planners better prepare for flooding and weather-related events, understand salmon activity and even restore rivers.

Tropical forests are crucial for sucking up carbon dioxide from the atmosphere. But they're also subject to intense storms that can cause 'windthrow' -- the uprooting or breaking of trees. A new study finds that more extreme thunderstorms from climate change will likely cause a greater number of large windthrow events in the Amazon, which could impact the rainforest's ability to serve as a carbon sink.

Flow batteries offer a solution. Electrolytes flow through electrochemical cells from storage tanks in this rechargeable battery. The existing flow battery technologies cost more than $200/kilowatt hour and are too expensive for practical application, but engineers have now developed a more compact flow battery cell configuration that reduces the size of the cell by 75%, and correspondingly reduces the size and cost of the entire flow battery. The work could revolutionize how everything from major commercial buildings to residential homes are powered.

Disturbances to Earth's magnetic field can lead birds astray -- a phenomenon scientists call 'vagrancy' -- even in perfect weather, and especially during fall migration. While other factors such as weather likely play bigger roles in causing vagrancy, researchers found a strong correlation between birds that were captured far outside of their expected range and the geomagnetic disturbances that occurred during both fall and spring migrations.

Earth's average surface temperature in 2022 tied with 2015 as the fifth warmest on record, according to an analysis by NASA. Continuing the planet's long-term warming trend, global temperatures in 2022 were 1.6 degrees Fahrenheit (0.89 degrees Celsius) above the average for NASA's baseline period (1951-1980), scientists report.

Combining satellite technology with machine learning may allow scientists to better track and prepare for climate-induced natural hazards, according to new research.

Vital winter ice road infrastructure may be cracking and sinking under the load of an unseasonably warm start to the new year across Europe and North America. New research warns that ice roads, essential for moving people, food, medicine and fuel in remote northern communities, as well as heavy machinery used by industry, may become unsustainable as the climate warms. This poses significant issues this century.

Translating electrochemical performance of large format batteries to microscale power sources has been a long-standing technological challenge, limiting the ability of batteries to power microdevices, microrobots and implantable medical devices. Researchers have created a high-voltage microbattery (> 9 V), with high-energy and -power density, unparalleled by any existing battery design.

Despite recent, torrential rains, most of Southern California remains in a drought. Accordingly, many residents plant trees prized for drought tolerance, but a new study shows that these trees lose this tolerance once they're watered.
