Engineers overcome radiation challenge with custom silicon chips

The Large Hadron Collider (LHC) is tough on electronics. Situated inside a 17-mile-long tunnel that runs in a circle under the border between Switzerland and France, this massive scientific instrument accelerates particles close to the speed of light before smashing them together. The collisions yield tiny maelstroms of particles and energy that hint at answers to fundamental questions about the building blocks of matter.

Those collisions produce an enormous amount of data—and enough radiation to scramble the bits and logic inside almost any piece of electronic equipment.

That presents a challenge to CERN’s physicists as they attempt to probe deeper into the mysteries of the Higgs boson and other fundamental particles. Off-the-shelf components simply can’t survive the inside the accelerator, and the market for radiation-resistant circuits is too small to entice investment from commercial chip manufacturers.

New software simulates cancer cell behavior using genomics and computational models

In the same vein as weather forecast models that predict developing storms, researchers have now developed a method to predict the cell activity in tissues over time. The new software combines genomics technologies with computational modeling to predict cell changes in behavior, such as communication between cells that could cause cancer cells to flourish.

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
