Abstract: With its high penetration, spaceborne photon-counting LiDAR can acquire the vertical structure of vegetation, which can be used for high-precision inversion of vegetation vertical parameters ...

For the first time, scientists have directly measured “ultraweak” photon emissions from living organisms. In rats this glow fades rapidly after death. In plants it brightens under stress. In the ...

Quantum technologies are systems that can compute data, sense their surrounding environment or perform other functions leveraging quantum mechanical effects. Connecting these technologies over long ...

Abstract: Photon-efficient imaging founded on single-photon light detection and ranging (LiDAR) has significantly broadened the scope of human vision. Nevertheless, two major challenges impede its ...

It’s a game created in a virtual reality space, surrounded by walls on all four sides. Players shoot spheres at each other, aiming to get their sphere into the opponent’s goal, which requires quick ...

About 80% of the universe's mass is thought to consist of dark matter. Yet, little is known about the composition and structure of the particles that make up dark matter, presenting physicists with ...

Physicists have, for the first time, shown that even a single photon obeys one of nature’s strictest rules: conservation of angular momentum. Achieved only once in a billion attempts, this needle-in-a ...

A project at Switzerland's EPFL research center has developed a new variant of fluorescence lifetime imaging microscopy (FLIM) that could substantially accelerate the imaging operation. Described in ...

The new approach uses a purely optical technique called stimulated two-photon excitation to generate streams of photons in different polarization states directly from a quantum dot without requiring ...

Nostalgics and newbies alike have swarmed to classic Valve shooter Counter-Strike Source. Hailed as one of the defining FPS games of its era, CS Source is now furiously bunnyhopping its way up the ...

You can now order an “Iron Dome” for mosquitoes. Its name is the Photon Matrix, a black box about the size of a smartphone that can detect, track, and eliminate mosquitoes mid-flight using an ...
