Droplet Levitation Is a New Way to Explore Airborne Viruses and Microorganisms

Researchers report achieving self-sustaining and long-term levitation of millimeter-sized droplets of several different liquids without any external forces. To get the droplets to levitate, they use solutocapillary convection, which occurs when a ...

Small-Winged and Lighter Colored Butterflies Likely to Be at Greatest Threat from Climate Change

彩色的蝴蝶likel Small-winged、更轻y to be at greatest threat from climate change. The family, wing length and wing colour of tropical butterflies all influence their ability to withstand rising temperatures, say ecologists. The ...

Thermal Cloak Passively Keeps Electric Vehicles Cool in the Summer and Warm in the Winter

When an electric vehicle is parked outside, its temperature can swing wildly from day to night and season to season, which can lead to deterioration of the battery. To dampen these fluctuations and extend the battery's lifespan, researchers have ...

The Ground Is Deforming, and Buildings Aren't Ready

A new study has linked underground climate change to the shifting ground beneath urban areas. The phenomenon is affecting all major urban areas around the globe, causing civil structures and infrastructures to ...
