From afar, the Sun looks calm and peaceful in our daytime skies. But up close, it’s an erupting, chaotic display of solar activity the likes of which astrophysicists didn’t expect until the last year or so.

“We didn’t think the Sun was going to be as active this particular cycle, but the observations are completely opposite,” Andrew Gerrard, the department chair and director of the Center for Solar-Terrestrial Research at New Jersey Institute of Technology, told Business Insider.

Solar cycles typically occur every 11 years. Within that time, the Sun oscillates from minimum to maximum solar activity, with maximum activity peaking in the middle of the cycle when the Sun’s magnetic fields flip.

A new vaccine designed to prime the immune system to recognise and fight lung cancer has been tested on UK patients for the first time.

Researchers leading the trial have said that BioNTech’s BNT116 vaccine could improve survival rates among people with the disease, and hope that it could eventually become the standard of care worldwide.

It works by presenting the immune system with tumour markers from non-small cell lung cancer, the most common form of the disease, to prime the body to fight cancer cells expressing these markers.

We present the direct experimental observation of the formation of a diamagnetic cavity and magneto-Rayleigh-Taylor (MRT) instability in a betaapprox1 high energy density plasma. Proton radiography is used to measure the two dimensional path-integrated magnetic field in a laser-produced plasma propagating parallel to a preimposed magnetic field. Flutelike structures, associated with the MRT instability, are observed to grow at the surface of the cavity, with a measured wavelength of 1.2 mm and growth time of 4 ns. These measurements are in good agreement with predictions of three dimensional magnetohydrodynamic simulations using the GORGON code.

Materials that exhibit superconducting properties at high temperatures, known as high-temperature superconductors, have been the focus of numerous recent studies, as they can be used to develop new technologies that perform well at higher temperatures. Although high-temperature superconductivity has been widely investigated, its underlying physics is not yet fully understood.

Via testing with a skin stand-in, a trio of physicists at Technical University of Denmark has ranked the types of paper that are the most likely to cause a paper cut. In an article published in Physical Review E, Sif Fink Arnbjerg-Nielsen, Matthew Biviano and Kaare Jensen tested the cutting ability and circumstances involved in paper cuts to compile their rankings.

In recent years, advances in photonics and materials science have led to remarkable developments in sensor technology, pushing the boundaries of what can be detected and measured. Among these innovations, non-Hermitian physics has emerged as a crucial area of research, offering new ways to manipulate light and enhance sensor sensitivity.

A research team has discovered the Fano resonance interference effect between mixed atomic spins. They proposed a novel magnetic noise suppression technique, reducing magnetic noise interference by at least two orders of magnitude. The study was published in Physical Review Letters. The team was led by Prof. Peng Xinhua and Associate Prof. Jiang Min from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS)
