Using the Rozhen National Astronomical Observatory, Bulgarian astronomers have conducted optical photometric observations of an ultracompact binary known as GP Com. Results of the observational campaign, presented in the Proceedings of the Bulgarian Academy of Sciences, shed more light on the properties of this system.

It has been a dream of astronomers and solar scientists for ages. A new mission gives solar researchers a powerful new tool in their arsenal: on-demand, total solar eclipses. Launched in 2024, The European Space Agency’s Proba-3 mission has proven the feasibility of a free-flying, space-based coronagraph. Now, the first science results from the mission are giving us a view of the origin of space weather. The results were recently published in The Astrophysical Journal Letters.

The concept of spacetime, first described in Einstein’s theory of general relativity, has since been widely studied by many physicists worldwide. Spacetime is described mathematically as a four-dimensional (4D) continuum in which physical events occur, which merges three-dimensional (3D) space, with one-dimensional (1D) time.

For the first time, a research team has demonstrated, in a metal-wall environment, a plasma regime that simultaneously achieves partial divertor detachment, an edge-localized-mode (ELM)-free high-confinement mode (H-mode), and high pedestal performance. This integrated regime was sustained on a minute scale and the work is published in Physical Review Letters.

In the increasingly digital world, the demand for faster, more efficient and miniaturized optical devices is ever-growing. From high-speed internet and secure quantum communications to advanced medical imaging and precision manufacturing, the backbone of these technologies is light, specifically how we can control and manipulate it at the nanoscale.

Spintronic devices enable data processing with significantly lower energy consumption. They are based on the interaction between ferromagnetic and antiferromagnetic layers. Now, a team from Freie Universität Berlin, HZB and Uppsala University has succeeded in tracking—separately for each layer—how the magnetic order changes after a short laser pulse has excited the system. The researchers were also able to identify the main cause of the loss of antiferromagnetic order in the oxide layer: The excitation is transported from the hot electrons in the ferromagnetic metal to the spins in the antiferromagnet. The findings are published in the journal Physical Review Letters.

A scientific discovery by researchers at Tel Aviv University’s School of Chemistry offers a new perspective on a long-standing scientific mystery: how does a flowing liquid suddenly become a rigid, almost frozen material, without changing its structure? This phenomenon, known as the “glass transition,” has puzzled physicists for over a hundred years. The study proposes a new experimental approach to observing this elusive process—by tracking the motion of tiny particles that serve as microscopic “sensors” within the material.

Researchers at Tampere University have recently demonstrated that light can be used to precisely reshape soft materials without mechanical contact. They have developed light-responsive hydrogel thin films that enable programmable surfaces with high sensitivity, rapid response, precise spatial control and reversibility. The technology opens new possibilities for tunable devices in photonics, sensing and biomedicine.

A new study by University of Maryland chemical physicists demonstrates how to control the nuclear spin of molecular hydrogen (H2) by simply freezing it in dry ice. This new technique, published in the journal Physical Review Letters, could improve energy storage for hydrogen fuel, memory for quantum computing and the ability to measure comet temperatures in outer space.
