In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.

Researchers have developed an eco-friendly refrigeration device with record-breaking cooling performance in the world, setting to transform industries reliant on cooling and reduce global energy use. With a boost in efficiency of over 48%, the new elastocaloric cooling technology opens a promising avenue for accelerating the commercialization of this disruptive technology and addressing the environmental challenges associated with traditional cooling systems.

The design of streets and layout of buildings have an impact on a city's resilience in the face of increasingly severe floods brought on by climate change. Researchers look at buildings and other urban structures as physicists consider elements in complex material systems. With this insight, the researchers have developed a new approach to urban flood modelling and found their results helpful in analyzing city-to-city variations in flood risk globally.

Researchers are measuring and scanning samples for a global 'hailstone library'. Storm simulations using 3-D modelling of real hailstones -- in all sorts of weird shapes from oblong to flat discs or with spikes coming out -- show it behaves differently than spherical hail shapes. Data from the hail library could lead to more accurate storm forecasts.

A groundbreaking technology has been unveiled that improves the efficiency of thermoelectric materials, which are key in converting waste heat into electricity, by altering their geometry to resemble an hourglass. Unlike previous research that solely depended on the material properties of thermoelectric substances, this new approach is expected to have widespread applications in thermoelectric power generation.

On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.

As global warming intensifies, people increasingly suffer from extreme heat. For those working in a high-temperature environment indoors or outdoors, keeping thermally comfortable becomes particularly crucial. A team has now developed thermally-insulated and breathable soft robotic clothing that can automatically adapt to changing ambient temperatures, thereby helping to ensure worker safety in hot environments.

Using nighttime lightdata from NASA, remote sensing, official outage records and census information, a study reveals notable differences in power-restoration rates between urbanized and rural areas and between disadvantaged and more affluent communities after Hurricane Michael in Florida's Panhandle. Block groups with higher proportions of minorities, multi-family housing units, rural locations, and households receiving public assistance experienced slower restoration of power compared to urban and more affluent neighborhoods.

Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.
