Electron Irradiation Study Narrows Theories on Nickelate Superconductivity

Researchers have taken an unconventional approach to understanding nickelate superconductors by deliberately introducing atomic defects using high-energy electron irradiation. The systematic study, published in Physical Review Letters, helps eliminate competing theories about how superconductivity emerges in these promising materials. This counterintuitive method of damaging high-quality samples provides crucial insights into the fundamental mechanisms driving superconductivity in nickelates.

A Backward Approach to Forward Progress

In a surprising twist, an international research collaboration has made significant headway in understanding superconducting nickelates by systematically damaging some of the best available samples. According to recently published research, scientists from MPI-CPfS teamed up with Stanford University and Ecole Polytechnique to bombard superconducting nickelate thin films with extremely high-energy electrons, deliberately introducing atomic-scale defects.

Stanford Team Develops Electromagnetic Cell Sorter That Levitates Cells by Density

Researchers at Stanford Medicine have developed a novel cell sorting device that uses electromagnetic forces to levitate and separate cells based on density. The technology enables gentle, label-free sorting of live versus dead cells and identification of cancer cell clusters without damaging samples.

A Magnetic Approach to Cell Sorting

What looks like cellular magic—cells floating upward from a liquid medium to hover at precise heights—is actually a sophisticated new sorting technology emerging from Stanford Medicine laboratories. According to recent reports in the Proceedings of the National Academy of Sciences, researchers have developed an electromagnetic device that levitates cells to separate them by type and condition without physical contact.

Satellite Data Reveals Magnetic Clues Before Major Myanmar Earthquake

Researchers have identified distinctive magnetic field anomalies in satellite data up to eight days before the devastating 2025 Myanmar earthquake. The study suggests these electromagnetic signals could contribute to future short-term earthquake forecasting systems.

Pre-Earthquake Magnetic Signals Detected

Scientists have uncovered magnetic field anomalies that appeared days before the devastating Mw7.7 earthquake that struck Myanmar on March 28, 2025, according to a new study published in Scientific Reports. The research team analyzed data from the European Space Agency’s Swarm satellite constellation, which revealed detectable disturbances in the Earth’s magnetic field beginning up to eight days before the seismic event that killed over 5,000 people.
