Unleashing the power of AI to track animal behavior

Movement offers a window into how the brain operates and controls the body. From clipboard-and-pen observation to modern artificial intelligence-based techniques, tracking human and animal movement has come a long way. Current ...

A new technique to detect invisibility cloaks

A study developed by researchers from the Universitat Politècnica de València (UPV), associated with the Nanophotonics Technology Center (NTC) and the company DAS Photonics, promises to revolutionize the design of so-called ...

Acoustics researchers develop novel underwater carpet cloak

Acoustic camouflage, realized by controlling wave propagation, has attracted much attention in recent years. Aided by a reflecting surface, acoustic carpet cloak has become one of the most practically feasible invisibility ...

Physicists embark on a hunt for a long-sought quantum glow

For "Star Wars" fans, the streaking stars seen from the cockpit of the Millennium Falcon as it jumps to hyperspace is a canonical image. But what would a pilot actually see if she could accelerate in an instant through the ...

Bending light for safer driving; invisibility cloaks to come?

Optical cloaking allows objects to be hidden in plain sight or to become invisible by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, like in the "Harry Potter" books, ...

Dashing the dream of ideal 'invisibility' cloaks for stress waves

Whether Harry Potter's invisibility cloak, which perfectly steers light waves around objects to make them invisible, will ever become reality remains to be seen, but perfecting a more crucial cloak is impossible, a new study ...

Invisible tags: Physicists write, read and erase using light

A team of physicists headed by Professor Sebastian Reineke of TU Dresden has developed a new method of storing information in fully transparent plastic foils. Their innovative idea has been published in Science Advances.
