Mini antimatter accelerator could rival the likes of the Large Hadron Collider

Researchers have found a way to accelerate antimatter in a 1000x smaller space than current accelerators, boosting the science of exotic particles.

Diamond-based sensors enable spintronics and next-generation MRI

Sensors developed under the DIADEMS project and capable of measuring magnetic fields with unprecedented accuracy are on the path to commercialisation. The technology has already spurred the creation of four start-ups.

SNS completes full neutron production cycle at record power level

The Spallation Neutron Source at the Department of Energy's Oak Ridge National Laboratory has reached a new milestone by operating a complete neutron production run cycle at 1.3 megawatts.

Surprise slow electrons are produced when intense lasers hit clusters of atoms

Scientists found that relatively slow electrons are produced when intense lasers interact with small clusters of atoms, upturning current theories.

NASA Invests in Concepts for a Vibrant Future Commercial Space Economy

In an ongoing effort to foster commercial activity in space, NASA has selected 13 companies to study the future of commercial human spaceflight in low-Earth orbit, including long-range opportunities for the International Space Station.

NASA Glenn Selects Winners of Drop Tower Challenge

NASA's Glenn Research Center in Cleveland has selected winners of the 2018 Microgravity Expulsion from Water Experiments Challenge. The winning teams have been invited to participate in the American Society for Gravitational and Space Research (ASGSR) conference in Washington D.C. in November.

Tying down electrons with nanoribbons

Nanoribbons are promising topological materials displaying novel electronic properties. Chemists and physicists have found a way to join two different types of nanoribbon to create a topological insulator that confines single electrons to the junction between them. Alternating nanoribbon types create a chain of interacting electrons that act as metals, insulators or interacting spins -- qubits for a quantum computer -- depending on separation. This opens the door to designer materials with unique quantum properties.

Novel approach to coherent control of a three-level quantum system

For the first time, researchers were able to study quantum interference in a three-level quantum system and thereby control the behavior of individual electron spins. To this end, they used a novel nanostructure, in which a quantum system is integrated into a nanoscale mechanical oscillator in form of a diamond cantilever.

NASA Announces New Partnerships to Develop Space Exploration Technologies

NASA is partnering with six U.S. companies to develop 10 “tipping point” technologies that have the potential to significantly benefit the commercial space economy and future NASA missions, including lunar lander and deep space rocket engine technologies.

Aboard the ISS, researchers investigate complex dust behavior in plasmas

400 kilometers above Earth, researchers examined waves in complex plasma under microgravity conditions and found that the microparticles behaved in nonuniform ways in the presence of varying electrical fields. They report some of the first findings from the Plasma-Kristall 4 experiment.
