NASA Announces Media Briefing on New Van Allen Probes Results

NASA will hold a news conference at 2 p.m. EST, Thursday, Feb. 28, to discuss new observations from NASA's twin Van Allen Probes, which are studying Earth's radiation belts. The briefing will be held at the Johns Hopkins University Applied Physics Laboratory, Kossiakoff Center, 11100 Johns Hopkins Rd., in Laurel, Md.

NASA Hosts Media Teleconference About Black Hole Studies

NASA will host a news teleconference at 1 p.m. EST, Wednesday, Feb. 27, to announce black hole observations from its newest X-ray telescope, the Nuclear Spectroscopic Telescope Array (NuSTAR), and the European Space Agency's XMM-Newton X-ray telescope.

Scientists develop a whole new way of harvesting energy from the sun

A new method of harvesting the sun's energy is emerging. Though still in its infancy, the research promises to convert sunlight into energy using a process based on metals that are more robust than many of the semiconductors used in conventional methods.

Laser mastery narrows down sources of superconductivity

Uncovering the mechanism behind high-temperature superconductivity -- a phenomenon with tremendous value to advances in energy efficiency and sustainability -- remains one of the greatest and most pressing puzzles in physics. Now, using precise laser pulses and atomically perfect 2-D materials, scientists have ruled out one possible source of HTS: Fleeting fluctuations called charge-density waves.

Quantum algorithm breakthrough: Performs a true calculation for the first time

Scientists have demonstrated a quantum algorithm that performs a true calculation for the first time. Quantum algorithms could one day enable the design of new materials, pharmaceuticals or clean energy devices.

Better power grid synchronization may enable smart grids to self-recover from failures

(Phys.org)—Although the LHC has often been called the largest machine in the world, that title may be more appropriately given to something much more familiar: power grids. Consisting of thousands of generators and substations linked across thousands of miles, these networks form the backbone of society in developed countries. Yet most of the grids that power our modern economy are based on technology from the 1960s, even though power demands have changed dramatically since then.

Creating next-generation materials able to operate in the toughest environments

Scientists have launched a new research project to develop next-generation materials able to operate in the most extreme environments.

Formation of nanoparticles can now be studied molecule-by-molecule

Atmospheric aerosol particles affect our climate by slowing down the global warming, research suggests. Scientists have succeeded in developing measurement techniques that allow detection of aerosol nucleation starting from the formation of clusters from vapor molecules, and the growth of these clusters into aerosol particles.

Researchers discover a way to generate an electron Airy beam

(Phys.org)—A team of physicists in Israel has succeeded in generating an electron Airy beam for the first time. As they describe in their paper published in the journal Nature, the researchers used a technique similar to that used by previous researchers to create Airy beams based on light.

NASA Astronaut Talks Space With Ventura County Students

NASA astronaut and U.S. Navy captain Stephen Bowen, a veteran of three NASA spaceflights, is set to visit two Ventura, Calif., schools on Wednesday, Feb. 27, to discuss his work at NASA and share his spaceflight experience with students.
