This is a condensation trail, or contrail, left behind an aircraft.Credit: Courtesy of Mick West Well-understood physical and chemical processes can easily explain the alleged evidence of a secret, large-scale atmospheric spraying program, commonly referred to as "chemtrails" or "covert...
Laser light coupled into the microfiber.Credit: OIST Light can take many different forms. Even in our day-to-day life, sunlight is vastly different from fluorescent light. In physics, when studying interactions between light and tiny particles, the shape of the light...
Artistic image of light trapped on the surface of a nanoparticle topological insulator.Credit: Vincenzo Giannini New research suggests that it is possible to create a new form of light by binding light to a single electron, combining the properties of...
UNM Research Assistant Aram Gragossian tests lasers in one of the Department of Physics & Astronomy's optics laboratories. Credit: University of New Mexico   When most people think about lasers, they usually imagine them generating heat and even setting something on...
This is a section from the crystal lattice of Calcium-chromium oxide showing how the spins are subject to conflicting demands. In this ball-and-stick model, the green and red sticks connecting the atoms (grey and black balls) represent ferromagnetic interactions...
Ortho-hydrogen converts to para-hydrogen by releasing energy to the ice surface. The conversion rate differed depending on the ice temperature.Credit: Naoki Watanabe, Hokkaido University Scientists at Hokkaido University have revealed temperature-dependent energy-state conversion of molecular hydrogen on ice surfaces, suggesting...

Emission spectra are a widely used method for identifying chemical compounds; the bright lines reveal the different frequencies of light that can be emitted by an atom. Here, a normal emission spectrum for an atom in a high-energy state...
