Technion researchers have developed accurate radiation sources that are expected to lead to breakthroughs in medical imaging and other areas. They have developed precise radiation sources that may replace the expensive and cumbersome facilities currently used for such tasks. The suggested apparatus produces controlled radiation with a narrow spectrum that can be tuned with high resolution, at a relatively low energy investment. The findings are likely to lead to breakthroughs in a variety of fields, including the analysis of chemicals and biological materials, medical imaging, X-ray equipment for security screening, and other uses of accurate X-ray sources.

Published in the journal Nature Photonics, the study was led by Professor Ido Kaminer and his master’s student Michael Shentcis as part of a collaboration with several research institutes at the Technion: the Andrew and Erna Viterbi Faculty of Electrical Engineering, the Solid State Institute, the Russell Berrie Nanotechnology Institute (RBNI), and the Helen Diller Center for Quantum Science, Matter and Engineering.

The researchers’ paper shows an experimental observation that provides the first proof-of-concept for theoretical models developed over the last decade in a series of constitutive articles. The first article on the subject also appeared in Nature Photonics. Written by Prof. Kaminer during his postdoc at MIT, under the supervision of Prof. Marin Soljacic and Prof. John Joannopoulos, that paper presented theoretically how two-dimensional materials can create X-rays. According to Prof. Kaminer, “that article marked the beginning of a journey towards radiation sources based on the unique physics of two-dimensional materials and their various combinations—heterostructures. We have built on the theoretical breakthrough from that article to develop a series of follow-up articles, and now, we are excited to announce the first experimental observation on the creation of X-ray radiation from such materials, while precisely controlling the radiation parameters.”

WASHINGTON — Northrop Grumman announced it will not move forward with the development of the OmegA rocket. The vehicle was designed for the sole purpose of competing for a National Security Space Launch contract award but didn’t make the cut.

“We have chosen not to continue development of the OmegA launch system at this time,” Northrop Grumman spokeswoman Jennifer Bowman said in a statement. “We look forward to continuing to play a key role in National Security Space Launch missions and leveraging our OmegA investments in other activities across our business.”

Bowman said the company will not be protesting the U.S. Space Force’s decision to select United Launch Alliance and SpaceX for the NSSL contracts.

🤔 “The White House today detailed the establishment of 12 new research institutes focused on AI and quantum information science. Agencies including the National Science Foundation (NSF), U.S. Department of Homeland Security, and U.S. Department of Energy (DOE) have committed to investing tens of millions of dollars in centers intended to serve as nodes for AI and quantum computing study.

Laments over the AI talent shortage in the U.S. have become a familiar refrain. While higher education enrollment in AI-relevant fields like computer science has risen rapidly in recent years, few colleges have been able to meet student demand due to a lack of staffing. In June, the Trump administration imposed a ban on U.S. entry for workers on certain visas — including for high-skilled H-1B visa holders, an estimated 35% of whom have an AI-related degree — through the end of the year. And Trump has toyed with the idea of suspending the Optional Practical Training program, which allows international students to work for up to three years in the U.S.”

The White House announced the creation of AI and quantum research institutes funded by billions in venture and taxpayer dollars.

This piece was written as part of the Artificial Intelligence and International Stability Project at the Center for a New American Security, an independent, nonprofit organization based in Washington, D.C. Funded by Carnegie Corporation of New York, the project promotes thinking and analysis on AI and international stability. Given the likely importance that advances in artificial intelligence could play in shaping our future, it is critical to begin a discussion about ways to take advantage of the benefits of AI and autonomous systems, while mitigating the risks. The views expressed here are solely those of the author and do not represent positions of IEEE Spectrum or the IEEE.

While we were all busy watching the Perseverance rover head off on its journey to Mars, NASA’s asteroid sample mission has been gearing up for its big moment. The Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx for short) has completed its final test approach of the surface. The next time it descends, OSIRIS-REx will scoop up pieces of the asteroid Bennu for return to Earth.

NASA launched OSIRIS-REx in 2016, sending it off to intercept 101955 Bennu, a carbonaceous asteroid about 1,610 feet (490 meters) in diameter. Bennu does get very close to Earth at points in its orbit — there’s even a small chance that it could impact the Earth in the next few centuries. Currently, it’s safely out of the way about 2 AU distant (an AU is the distance between Earth and the sun).
