Wheat containing exotic DNA from wild relatives benefits from up to 50 per cent higher yields in hot weather compared with elite lines lacking these genes.

A researcher has developed technology that could prevent electric vehicle fires, like those caused by saltwater flooding from Hurricane Ian. The technology, an aqueous battery, replaces the volatile and highly flammable organic solvents found in electric vehicle lithium-ion batteries with saltwater to create a battery that is safer, faster charging, just as powerful and won't short circuit during flooding.

A research team has built and tested a new interlayer to prevent dissolution of the sulfur cathode in lithium-sulfur batteries. This new interlayer increases Li-S cell capacity and maintains it over hundreds of cycles.

The severity of marine heatwaves (MHWs) that are increasingly impacting ocean ecosystems, including vulnerable coral reefs, has primarily been assessed using remotely sensed sea-surface temperatures (SSTs), without information relevant to heating across ecosystem depths. Here, using a rare combination of SST, high-resolution in-situ temperatures, and sea level anomalies observed over 15 years near Moorea, French Polynesia, we document subsurface MHWs that have been paradoxical in comparison to SST metrics and associated with unexpected coral bleaching across depths. Variations in the depth range and severity of MHWs was driven by mesoscale (10s to 100s of km) eddies that altered sea levels and thermocline depths and decreased (2007, 2017 and 2019) or increased (2012, 2015, 2016) internal-wave cooling.

Researchers examine the role of spring heatwaves on the melting rates of mountain snowpacks across the West. They found that in April 2021, record-breaking snowmelt rates occurred at 24% of all mountain snowpack monitoring sites in the region, further compounding the impacts of extended drought conditions.

Lithium is expensive and limited, necessitating the development of efficient energy storage systems beyond lithium-ion batteries. Sodium is a promising candidate. However, sodium ions, being large and sluggish, hamper sodium-ion battery (SIB) anode performance. Researchers have recently developed pyrolyzed quinacridones, new carbonaceous SIB anode materials, that are efficient, easily prepared, and exhibit excellent electrochemical properties, including high sodium-ion storage performance and cycling stability.

Tropical cyclone researchers report a warming climate could increase the number of tropical cyclones and their intensity in the North Atlantic, potentially creating more and stronger hurricanes. In a second research paper, researchers examine a possible explanation for the relatively constant number of tropical cyclones around the globe every year.

Researchers now have a much better understanding of how climate change can impact and cause sea water temperatures on one side of the Indian Ocean to be so much warmer or cooler than the temperatures on the other -- a phenomenon that can lead to sometimes deadly weather-related events like megadroughts in East Africa and severe flooding in Indonesia.

Global warming is expected to lead to an accumulation of particularly intense hurricanes in the United States. This may substantially increase the economic losses caused by these storms. Better insurance could effectively mitigate the climate change-induced increase in economic losses. This is shown in a new study examining the effectiveness of climate risk insurance in the US.

A new study has found that individuals from disadvantaged backgrounds are more likely to experience disaster-related home loss, and they are also more likely to develop functional limitations following the disaster.

Engineers have announced the development of solid electrolytes with enhanced atmospheric stability.

For many people, holidays in the snow are as much a part of the end of the year as Christmas trees and fireworks. As global warming progresses, however, white slopes are becoming increasingly rare. Researchers have calculated how well one of Switzerland's largest ski resorts will remain snow reliable with technical snow-making by the year 2100, and how much water this snow will consume.

As the supersonic solar wind surges towards Earth, its interaction with our planet's magnetic field creates a shock to deflect its flow, and a foreshock filled with electromagnetic waves. How these waves can propagate to the other side of the shock has long remained a mystery.

Scientists give the lay of the land in the quest for electrolytes that could enable revolutionary battery chemistries.

Chemists use flash Joule heating to recover graphite anodes from spent lithium-ion batteries at a cost of about $118 per ton.

A polymer-based electrolyte makes for batteries that keep working -- and don't catch fire -- when heated to over 140 degrees F.

Researchers are hoping that a new, low-cost battery which holds four times the energy capacity of lithium-ion batteries and is far cheaper to produce will significantly reduce the cost of transitioning to a decarbonized economy.

Scientists used high energy x-rays to investigate the solid-electrolyte interphase, a chemical layer in batteries that's key to stabilizing lithium metal anodes. Chemists unraveled this complex chemical mechanisms that is crucial for boosting energy density.

Researchers have developed a new method for producing a key component of lithium-ion batteries. The result is a more affordable battery from a faster, less wasteful process that uses less toxic material.
