New spacecraft will watch Earth’s shield take the hit as solar storms come roaring in

A joint European-Chinese spacecraft is set to blast off Tuesday to investigate what happens when extreme winds and giant explosions of plasma shot out from the sun slam into Earth’s magnetic shield.

We tested the new World Cup ball. This is what you need to know about how it will fly, dip and swerve

Every four years, the men’s World Cup delivers some certainties. The pitch dimensions are tightly regulated, offside is signaled with a flag, and referees end the match with a blast of a whistle. But one key piece of equipment is changed on purpose: the ball.

Neutrino flavor flips could be key to triggering supernovae

Despite being so elusive, neutrinos are produced in abundance in some of the most violent events in the universe. One of their strangest properties is that they can spontaneously switch between three types, or “flavors”: a phenomenon known as neutrino oscillation that remains poorly understood in extreme astrophysical environments.

First outbursting hot subdwarf binary discovered

An international team of astronomers has utilized the Zwicky Transient Facility (ZTF) and the Transiting Exoplanet Survey Satellite (TESS) to investigate a binary system designated ZTF J0007+4804. As a result, they have found that ZTF J0007+4804 is the first hot subdwarf-white dwarf system discovered that produces dwarf nova outbursts. The finding is reported in a paper published May 4 on the arXiv preprint server.

A hidden threshold enables tunable control of liquid crystal helices for energy-efficient technologies

Liquid crystals are an integral part of modern technology, ranging from displays to advanced sensory systems. In a study published in Scientific Reports, researchers from the Institute of Experimental Physics of the Slovak Academy of Sciences (IEP SAS) in Košice, in collaboration with international partners, have demonstrated how minute changes in material composition can achieve precise control over behavior in electric and magnetic fields.

Sunlight-powered generation of correlated photon pairs

Pairs of correlated or entangled photons are a foundational resource in quantum optics. They are most commonly produced through spontaneous parametric down-conversion (SPDC), a nonlinear optical process that typically relies on a stable, coherent laser to pump a nonlinear crystal. Because of this requirement, SPDC has long been viewed as impractical without laboratory-grade laser systems.

Physicists create hybrid light-matter particles that interact strongly enough to compute

Eighty years ago, Penn researchers J. Presper Eckert and John Mauchly launched the age of electronic computing by harnessing electrons to solve complex numerical problems with ENIAC, the world’s first general-purpose electronic computer. Today, that same architecture still underlies general computing, but electrons are beginning to show their limits. Because they carry a charge, they lose energy as heat, encounter resistance as they move through materials, and become harder to manage as chips incorporate more transistors and handle larger volumes of data.
