Scientists Develop a Light-Driven Three-Dimensional Plasmonic Nanosystem

This scissor-like nanosystem consisting of bundles of coiled up DNA (grey) measures only a few nanometers. In visible light, the two DNA ends (red) sticking out of the bundles are linked up with each other. When the researchers switch on the UV light, the system opens up. They can measure the opening and closing with the aid of physical changes ... Read More »

Physicists Test the Response Time of Electrons

Attosecond flashes of visible light make it possible to measure the delay with which electrons react to the exciting light because of their inertia. The characteristic form of the light wave arises because the researchers at the Max Planck Institute of Quantum Optics form the pulse from light of different wavelengths. Researchers from the Laboratory for Attosecond Physics generated for ... Read More »

New Research May Solve Longstanding Fusion Reactor Mystery

A view inside the Alcator C-Mod tokamak. New research from MIT shows two types of turbulence within plasma that cause significant heat loss. Solving this problem could take the world a step closer to fusion power which has the promise of limitless and relatively clean energy. One of the biggest obstacles to making fusion power practical — and realizing its ... Read More »

New Results from Large Underground Xenon (LUX) Dark Matter Experiment

(Photo by Matthew Kapust/Sanford Underground Research Facility) A new set of calibration techniques employed by LUX scientists has dramatically improved the sensitivity of the LUX Dark Matter Experiment. The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (SURF) in the Black Hills of ... Read More »

New Phase of Carbon Allows Researchers to Make Diamond Structures at Room Temperature

This is a scanning electron microscopy image of microdiamonds made using the new technique. Researchers at North Carolina State University have discovered a new phase of solid carbon and have developed a technique for using this carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air. The new phase of solid carbon, called Q-carbon, is ... Read More »

Physicists Achieve Quantum Entanglement at Room Temperature

Paul Klimov, a graduate student in the Institute for Molecular Engineering, adjusts the intensity of a laser beam during an experiment. Because the laser light lies within the infrared spectrum, it is invisible to the human eye. Courtesy of Awschalom Group A newly published study from the University of Chicago and Argonne National Laboratory demonstrates how macroscopic entanglement can be ... Read More »

Quantum Process Significantly Boosts the Energy That Can Be Harnessed from Sunlight

A newly published study details how a quantum process increases the number of electrons produced when light strikes a metal-dielectric interface. Researchers believe this finding could lead to better solar cells or light detectors. The new approach is based on the discovery that unexpected quantum effects increase the number of charge carriers, known as electrons and “holes,†that are knocked ... Read More »

Physicists Make First Ever Measurement of Antiproton Interactions

A new measurement by RHIC’s STAR collaboration reveals that the force between antiprotons (p) is attractive and strong—just like the force that holds ordinary protons (p) together within the nuclei of atoms. A team of scientists has announced the first ever measurement of antiproton interactions that make possible the existence of antimatter nuclei. The discovery gives physicists new ways to ...

MicroBooNE Physics Experiment Detects Its First Neutrino Candidates

This image shows an event display from the first accelerator-born neutrino candidates spotted with the MicroBooNE detector. MicroBooNE started receiving its very first neutrino beam from the Fermilab Booster accelerator on October 15, 2015. On November 2, 2015, sceiietnsts released the first neutrino event candidates that their automated neutrino event reconstruction identified. Halloween has come and gone, but Yale physicist ...

Glueball – A Particle Purely Made of Nuclear Force

Nucleons consist (left) of quarks (matter particles) and gluons (force particles). A glueball (right) is made up purely of gluons. Scientists from Vienna University believe they may have discovered the long-sought-after glueball, a particle composed of pure force. For decades, scientists have been looking for so-called “glueballsâ€. Now it seems they have been found at last. A glueball is an ... Read More »
