Electron beam method enables precise nanoscale carving and building of copper structures

Creating complex structures at the tiniest scales has long been a challenge for engineers. But new research from Georgia Tech shows how electron beams, already widely used in imaging and fabrication, can also be used as ultra-precise tools to both carve and build structures out of materials like copper.

The research group of Professor Andrei Fedorov at the George W. Woodruff School of Mechanical Engineering has discovered a technique that uses focused electron beams in a liquid environment to either remove or deposit copper, depending entirely on the surrounding chemistry.

By tuning the amount of in the solution, the researchers were able to control whether the beam etched away the material or deposited it, effectively allowing 3D sculpting at the atomic level.

Researchers demonstrate first bidirectional asymmetric frequency conversion in a single system

A research team in Korea has experimentally demonstrated, for the first time in the world, a nonlinear wave phenomenon that changes its frequency—either rising or falling—depending on which direction the waves come from.

Much like Janus, the Roman god with two faces looking in , the system exhibits different responses depending on the direction of the incoming wave. This groundbreaking work opens new horizons for technologies ranging from medical ultrasound imaging to advanced noise control.

The joint research team, led by Professor Junsuk Rho of POSTECH’s Departments of Mechanical Engineering, Chemical Engineering, Electrical Engineering, and the Graduate School of Convergence Science and Technology, along with Dr. Yeongtae Jang, Ph.D. candidate Beomseok Oh, and Professor Eunho Kim of Jeonbuk National University, has experimentally demonstrated a phenomenon of bidirectional asymmetric frequency conversion within a granular phononic crystal system.

Neutron beam platform unites simulation and biology for advanced therapy research

One of ANSTO’s advanced imaging instruments Dingo now delivers a rare fusion of simulation and radiobiology, becoming a launchpad for an innovative neutron therapy innovation.

This unique scientific capability comprises a single research platform for high-fidelity simulation, real-time dosimetry, and biological response data—all from a neutron beam instrument.

Two new papers published in Scientific Reports report how ANSTO researchers have adapted neutron tomography into a fully integrated testbed for neutron capture therapy research. The platform allows scientists to model conditions, plan experiments, and irradiate , all within a validated, operational system.

Thought To Be Impossible — Scientists Rewrite a Material’s “Magnetic DNA”

Is it magic? Physicists at the University of Konstanz have successfully altered the properties of a material using light and magnons in a non-thermal manner. What if it were possible to temporarily change a material so completely that it behaves like an entirely different one? No special chemical

Cosmic Death Spiral: Astronomers Catch Planet in Final Orbit Before Destruction

A team of astronomers led by Macquarie University has monitored the orbital decay of an extreme exoplanet to gain new insights into how stars dissipate energy. The exoplanet TOI-2109b, found 870 light-years away in the Hercules constellation of the Milky Way, stands out as one of the most extreme

Soco404 and Koske Malware Target Cloud Services with Cross-Platform Cryptomining Attacks

Threat hunters have disclosed two different malware campaigns that have targeted vulnerabilities and misconfigurations across cloud environments to deliver cryptocurrency miners.

The threat activity clusters have been codenamed Soco404 and Koske by cloud security firms Wiz and Aqua, respectively.

Soco404 “targets both Linux and Windows systems, deploying platform-specific malware,” Wiz researchers Maor Dokhanian, Shahar Dorfman, and Avigayil Mechtinger said. “They use process masquerading to disguise malicious activity as legitimate system processes.”

Earth and Space for Educators

This FREE features Inspiration4 astronaut Chris Sembroski and educator Erin Duncan-Sembroski, along with your hosts, planetary scientist Dr. Kirby Runyon and space educator Dr. Mark Wagner. The high-energy one-hour session is focused on providing an overview of the three-day Earth and Space Experience coming up on November 7–9, 2025. Register now to learn about the geology at specific locations in Southern New Mexico, and how these sites are analogs for the Moon, Mars, and elsewhere in the solar system. Time is also allocated for a Q&A opportunity with all four speakers… come ready with questions! Participation in this also includes access to free space education resources that you can take back to share with your students or others in your community.

Note: This is appropriate for educators, industry professionals, and space enthusiasts from all walks of life. Space education is for everyone!

Chris “Hanks” Sembroski is a commercial astronaut, U.S. Air Force veteran, and passionate advocate for space exploration and STEM education. Best known for his role as Mission Specialist on the historic Inspiration4 mission in 2021, Sembroski spent three days in space, completing 47 orbits as part of the first all-civilian crew. With degrees in aeronautics and a career dedicated to advancing aerospace innovation, he has contributed to groundbreaking projects like Blue Origin’s New Glenn program and teaches as an adjunct faculty member at Embry-Riddle Aeronautical University. Chris’s journey reflects a lifelong passion for human spaceflight, from launching model rockets in college, leading teams through simulated missions at U.S. Space Camp, to advocating for space policy in Washington, D.C. He continues to inspire the next generation through his work as a speaker, educator, and industry leader, embodying the spirit of generosity and exploration.
