Compact and lightweight metasurfaces—which use specifically designed and patterned nanostructures on a flat surface to focus, shape and control light—are a promising technology for wearable applications, especially virtual and augmented reality systems. Today, research teams painstakingly design the...

Aerodynamics of perching birds could inform aircraft design

 Physics General News
 17 May 2022
If you have ever watched a bird land on a tree branch, you may have noticed that it rapidly pitches its wings upward at a high angle to execute a smooth landing. However, for some birds, they land by folding their wings as they perch instead, creating a sweeping motion as they decelerate....

A new law unchains fusion energy

 Physics General News
 17 May 2022
Physicists at EPFL, within a large European collaboration, have revised one of the fundamental laws that has been foundational to plasma and fusion research for over three decades, even governing the design of megaprojects like ITER. The update shows that we can actually safely use more hydrogen...

Rocket engine exhaust pollution extends high into Earth's atmosphere

 Physics General News
 17 May 2022
Reusable space technology has led to a rise in space transportation at a lower cost, as popularized by commercial spaceflights of companies like SpaceX and Virgin Galactic. What is poorly understood, however, is rockets' propulsion emissions creating significant heating and compositional changes in...
