Falling stars hold clue for understanding dying stars

An international team of researchers has proposed a new method to investigate the inner workings of supernovae explosions. This new method uses meteorites, and is unique in that it can determine the contribution from electron anti-neutrinos, enigmatic particles which can't be tracked through other means.

Terahertz spectroscopy enters the single-molecule regime

Researchers showed that long-wavelength terahertz (THz) spectroscopy can detect motion of single molecules, not just molecular ensembles. They used a single-molecule transistor design, where pairs of metal electrodes trap isolated C60 molecules, focus the THz beam onto them, and measure current change caused by THz-induced oscillation. Two vibrational peaks were recorded. The measurement was sensitive enough to register slight peak-splitting caused by electron charging. This could promote wider use of THz spectroscopy.

NASA Invites Media to View Spacecraft to Study the Frontier of Space

NASA is inviting media to view NASA’s Ionospheric Connection Explorer (ICON) spacecraft Thursday, Oct. 4, ahead of its scheduled launch aboard a Northrop Grumman Pegasus XL rocket Saturday, Oct. 6, at 4 a.m. EDT from Cape Canaveral Air Force Station (CCAFS) in Florida.

NASA Invites Media to Witness Final Orion Parachute Test in Arizona Desert

NASA is inviting media to view the final test of the Orion spacecraft’s parachute system on Wednesday, Sept. 12, at the U.S. Army’s Yuma Proving Ground in Arizona. This test is the last in a series of eight to qualify the parachutes for crewed Orion missions to the Moon and beyond.

Cannibalistic materials feed on themselves to grow new nanostructures

Scientists have induced a two-dimensional material to cannibalize itself for atomic 'building blocks' from which stable structures formed. The findings provide insights that may improve design of 2-D materials for fast-charging energy-storage and electronic devices.

Hunting for dark quarks

Quarks are the smallest particles that we know of. In fact, according to the Standard Model of particle physics, which describes all known particles and their interactions, quarks should be infinitely small. If that's not mind-boggling enough, enter dark quarks – hypothetical particles that have been proposed to explain dark matter, an invisible form of matter that fills the universe and holds the Milky Way and other galaxies together.

Device harvests energy from low-frequency vibrations

A wearable energy-harvesting device could generate energy from the swing of an arm while walking or jogging, according to a team of researchers from Penn State's Materials Research Institute and the University of Utah. The device, about the size of a wristwatch, produces enough power to run a personal health monitoring system.

The potential harbingers of new physics persist in LHC data

For some time now, researchers have noted several anomalies in the decays of beauty mesons in the data coming in from the LHCb experiment at the Large Hadron Collider. Are they more than just statistical fluctuations? The latest analysis, taking into account so-called long-distance effects in the decays of particles, increases the probability that the anomalies are not an error in the measuring techniques.

NASA Awards Contract for Earth Science Mission Hosting Services

NASA has awarded a contract to General Atomics of San Diego, California, for services required to host the agency’s Multi-Angle Imager for Aerosols (MAIA) instrument on a commercial satellite in low-Earth orbit.

NASA Awards Contract to Upgrade Launch Pad Fuel System for World’s Largest Rocket

NASA has awarded a contract to Precision Mechanical, Inc., in Cocoa, Florida, for the manufacture, fabrication and installation of upgrades to the Liquid Hydrogen (LH2) System at Launch Complex 39B at NASA’s Kennedy Space Center in Florida.
