Popular Science announces second annual 'Brilliant 10:' the country's top young scientists
...m cryptography. Scientists have long wanted to use photons to send secret keys, but until now the technology hasn't been precise enough. Enter Nam, who recently built the world's most sensitive photon detector. By interacting with the quantum world, his device could make coded messages uncrackable. For a co...Lasers create new possibilities for biological technology
...cess. As a result, a well-synchronized stream of photons fires out of the system, boosted up to a high-energy, "soft" x-ray wavelength. Many of the most important technologies of the 20th century, such as the Internet and MRI imaging, emerged from the use of electromagnetic radiation ranging from radio wav...Optically recording millisecond brain nerve impulses
...extremely short, intense pulses. When two or three photons strike a biological molecule at the same time, their energies combine. This has the cumulative effect of delivering one photon -- with nearly twice the energy -- to the sample. By adjusting the plane of focus, a multiphoton microscope can produce a v...Bay area to get unique x-ray microscopy resource
... needed for electron microscopy." Microscopy using photons that fall within the visible light region of the electromagnetic spectrum remains the workhorse of biology because it enables scientists to examine living cells in their natural state. Resolution, however, is typically no better than 200 nanometers, ......um entanglement had only been achieved between two photons or two atoms, not one of each. In this experiment, a trapped cadmium ion in an excited state decays by one of several possible decay paths, emitting a photon that carries off information about the state of the de-excited atom. This is the first obser...3-D micro-imaging technology licensed to Carl Zeiss Jena

...echnique to enhance the near-surface absorption of photons by semiconductors using engineered nanostructures placed on the surface of the semiconductor. The approach leads to a substantial increase in optical absorption, even in silicon-based semiconductors. Now, Yu plans to adapt this technology to thin-fil...Briggs takes to the molecular level Darwin's findings on plants sensing the direction of light
...hat serves as the detector and decoder of the blue photons on which the seedling cues to determine the direction of light. The molecule, known as phototropin, is now being intensively studied because of its unique properties by chemists and biophysicists as well as plant biologists. Professor Briggs began ...Free electron laser reaches 10 kW
...e form of photons. As in a conventional laser, the photons are bounced between two mirrors and then emitted as a coherent beam of light. However, FEL operators can adjust the wavelength of the laser's emitted light by increasing or decreasing the energies of the electrons in the accelerator or the amount of ...Jefferson Lab detector technology aids development of cystic fibrosis therapy
