  • In the photoelectric effect, a photon ejects an electron from a material. Researchers have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their...
  • Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new...
  • Researchers have discovered a novel strategy for creating superatoms -- combinations of atoms that can mimic the properties of more than one group of elements of the periodic table. These superatoms...
  • The first examples of covalent organic frameworks (COFs) were discovered in 2005, but quality has been poor and preparation methods uncontrolled. Now researchers have produced high-quality versions...
  • Astronomers have made the most precise test of gravity outside our own solar system. By combining data taken with NASA's Hubble Space Telescope and the European Southern Observatory's Very Large...
