The Sun Is More Active Than Scientists Anticipated. Here’s What It Means For Us

Posted by in categories: physics, space

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.

The lung cancer signs everyone needs to know about as new vaccine announced

Posted by in category: biotech/medical

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.

Observation of a magneto-Rayleigh-Taylor instability in magnetically collimated plasma jets

Posted by in category: energy

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.

Study uncovers broken mirror symmetry in the Fermi-liquid-like phase of a cuprate

Posted by in categories: materials, physics

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.

New research suggests a way to capture physicists’ most wanted particle—gravitons

Posted by in categories: particle physics, quantum physics

A team led by Stevens professor Igor Pikovski has just outlined how to detect single gravitons, thought to be the quantum building blocks of gravity—and making that experiment real should be possible with quantum technology, they suggest, in the near future.

Paper types ranked by likelihood of paper cuts

Posted by in category: physics

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.

Reconfigurable sensor can detect particles 0.001 times the wavelength of light

Posted by in categories: materials, particle physics

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.

Quantum nonlocality demonstrated in first loophole-free test of Hardy’s paradox

Posted by in category: quantum physics

A research team has achieved the loophole-free test of Hardy’s paradox for the first time. The team successfully demonstrated Hardy’s nonlocality while closing both the detection efficiency loophole and the locality loophole.

Research team develops atomic comagnetometer that suppresses noise by two orders of magnitude

Posted by in category: futurism

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)
