Astronaut Shubhanshu Shukla has used a water blob to explain Earth's shape. Discover the physics of surface tension, rotation, and inertia in this space and physics explainer.

The surface tension of a liquid is a measure of the cohesive forces that hold the molecules together. It is responsible for a water drop assuming a spherical shape and for the effects of surfactants ...

NASA’s Perseverance rover produced breathable oxygen on Mars on April 20, 2021, marking the first time humans manufactured a ...

Researchers from North Carolina State University have used laser ablation to create ultra-stretchable, superomniphobic ...

Those of us who watch the Olympics as bystanders tend to smugly judge athletes for succumbing to pressure without ...

In the 1930s, the Switzer brothers stumbled onto a way to mimic fluorescence. That led to Day-Glo, which has been making the world a brighter place ever since ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.

Using gold flakes, salt water, and light, scientists have made the universe’s invisible binding forces visible in color. The discovery opens new possibilities for studying how matter organizes itself ...

Researchers at North Carolina State University have developed an ultra-stretchable material that repels nearly ...

We build a giant slingshot strong enough to launch full-size cars and decide to see how far we can push it. What starts as a simple test quickly escalates as tension increases and launches get more ...

Abstract: The reconfigurable intelligent surface (RIS) is a promising technology for overcoming the coverage hole in millimeter wave communications, which consists of many tunable passive elements and ...

Abstract: Future 6G networks demand a paradigm shift towards smart wireless environments with integrated communication, sensing, and security capabilities. Intelligent Omni-Surfaces (IOS) are emerging ...
