A look beyond the horizon of events

Black holes are still very mysterious celestial bodies which, according to the majority of physicists, do not, however, escape the laws of thermodynamics. As a result, these physical systems possess an entropy though no real agreement has been reached about the microscopic origin of this propriety and how it should be calculated. Scientists have now achieved important results in this calculation by applying a new formalism (Group Field Theory) of Loop Quantum Gravity (LQG), a very popular approach in the area of quantum gravity.

3D laser scanner runoff pushes new standard towards the finish line

Large-volume 3D laser scanners play an essential role in manufacturing large products (e.g., airplane wings), making measurements for large-scale construction (e.g., bridges), and other applications where very large structures must be measured in three dimensions. At present, however, there is no comprehensive standard to judge how well the instruments perform.

Possible case for fifth force of nature

A team of physicists at the University of California has uploaded a paper to the arXiv preprint server in which they suggest that work done by a team in Hungary last year might have revealed the existence of a fifth force of nature. Their paper has, quite naturally, caused quite a stir in the physics community as several groups have set a goal of reproducing the experiments conducted by the team at the Hungarian Academy of Science's Institute for Nuclear Research.

Upgraded PIP-II RFQ successfully takes first beam

In March, the Fermilab Accelerator Division successfully sent beam through a newly commissioned linear accelerator. The brand new radio-frequency quadrupole (RFQ) linac, designed and built by a team of engineers and physicists at Lawrence Berkeley National Laboratory, will be the start for a proposed upgrade to Fermilab's 800-MeV superconducting linear accelerator.

Scanning for skyrmions: Scientists directly image skyrmion cluster state transitions in iron-germanium nanodisks

Magnetic skyrmions, or noncoplanar swirling spin textures, are particle-like spin configurations with an integer topological charge that promise faster, denser memory storage. The hurdle to overcome in creating such devices is being able to understand single skyrmions in patterned nanoelements – but despite theoretical progress, real-world experimental studies of these entities have remained elusive.

NASA Awards Financial and Business Management Services Contract

NASA has selected Logical Innovations, Inc., of Houston to provide financial and business management services for the Office of the Chief Financial Officer, Office of Procurement and other entities at the agency's Johnson Space Center in Houston.

NASA Glenn’s Plum Brook Station Announces Open House Details

NASA Glenn’s Plum Brook Station is having a free public open house on June 11 and 12 from 10 a.m. to 6 p.m.

NASA Astronaut Kate Rubins Available for Interviews Before Space Station Launch

NASA astronaut Kate Rubins will be available for live satellite interviews from Moscow on Wednesday, June 1, before her launch to the International Space Station. She will answer questions about her upcoming mission aboard the world’s only orbiting laboratory from 9-10 a.m. EDT, airing live on NASA Television and streaming on the agency’s website.

Alabama Team Takes Top Robotic Honors

The seventh annual Robotics Mining Competition saw engineering teams from across the nation compete to design and build the most effective robotic excavation system.

VIDEO: ISS Astronauts Enjoy Dish Cooked Up by Students from Hampton, Virginia

Astronauts aboard the International Space Station recently feasted on a spicy Jamaican rice and beans with coconut milk entrée cooked up by a team of culinary students from Phoebus High School in Hampton, Virginia.
