Cambridge researchers have identified magnetic monopoles in hematite, suggesting new possibilities for advanced, eco-friendly computing technologies. This first-time observation of emergent monopoles in a natural magnet could unlock new avenues in quantum material research.
Researchers have discovered magnetic monopoles – isolated magnetic charges – in a material closely related to rust, a result that could be used to power greener and faster computing technologies.
Researchers led by the University of Cambridge used a technique known as diamond quantum sensing to observe swirling textures and faint magnetic signals on the surface of hematite, a type of iron oxide.
Brain networks are often represented by graph models that incorporate neuroimaging data from MRI or CT scans to represent functional or structural connections within the brain. These brain graphs can be used to understand how the organ changes over time.
Traditionally, however, these models treat the brain graphs as static, which can miss or ignore underlying changes that could signal the onset of disease or neurological disorders.
A collaborative team of researchers led by Lifang He, an assistant professor of computer science and engineering at Lehigh University, recently received a $1 million grant from the National Science Foundation, with $300,000 going to Lehigh, to develop new methods for modeling the dynamics of brain graphs using artificial intelligence that will generate more accurate, interpretable, and fair predictions when it comes to disease.

Study by the Universities of Bonn and St. Andrews proposes a new possible explanation for the Hubble tension.
The universe is expanding. How fast it does so is described by the so-called Hubble-Lemaitre constant. But there is a dispute about how big this constant actually is: Different measurement methods provide contradictory values. This so-called “Hubble tension” poses a puzzle for cosmologists. Researchers from the Universities of Bonn and St. Andrews are now proposing a new solution: Using an alternative theory of gravity, the discrepancy in the measured values can be easily explained — the Hubble tension disappears. The study has now been published in the Monthly Notices of the Royal Astronomical Society (MNRAS).

New research has unveiled an advancement in Light Detection and Ranging (LIDAR) technology, offering unparalleled sensitivity and precision in measuring the distance of remote objects.
This research, published in Physical Review Letters, is a result of a collaboration between the group of Professor Yoon-Ho Kim at POSTECH in South Korea, and the Quantum Science and Technology Hub at the University of Portsmouth.
Coherent LIDAR has long been a cornerstone in distance measurement, but its capabilities have been restrained by the coherence time of the light source. In a pioneering move, researchers have introduced two-photon LIDAR, eliminating the range limitations imposed by coherence time, to achieve accurate and precise ranging of a remote object situated far beyond the coherence time dictated by the spectral bandwidth of the light source.
