The claim, published by vals.ai, is drawing attention on Hacker News, where commenters are weighing how much the discovery relies on AI-driven materials screening and whether the candidates can be experimentally verified.

The Sun has produced its most powerful solar flare in a long while, and two large clouds of plasma ejected from the star are now moving toward Earth. Russian media are tracking the event closely, with readers asking whether it will trigger magnetic storms. Forecasters, however, say no significant geomagnetic disturbances are expected between October 5 and 11, despite the scale of the flare.

Forecasters have issued a G2 geomagnetic storm watch after a powerful solar eruption sent charged material toward Earth. The disturbance is expected to reach the planet's magnetic field, potentially triggering displays of the northern lights visible across the northern United States. Moderate storm levels can also affect satellite operations and power grids at high latitudes.

The NOAA Space Weather Prediction Center has issued a G2 moderate geomagnetic storm watch for October 9, raising chances of aurora sightings at unusually low latitudes. Attention is also on a new spacecraft capturing a burst of aurora around the North Pole and the SMILE satellite, which is ending an 18-year gap in X-ray observations of Earth's magnetic shield.

The European Space Agency's Solar Orbiter mission has tracked the origin of mysterious magnetic switchbacks, sudden S-shaped bends in the Sun's magnetic field that have puzzled scientists for decades. Findings suggest the switchbacks originate in the Sun's surface, shedding new light on solar wind behaviour and space weather.

New research published in Nature examines where magnetic switchbacks in the solar wind come from. These sudden, zigzag reversals in the Sun's magnetic field, observed by spacecraft including Parker Solar Probe, have puzzled scientists for years. The study argues that the kinks originate in the Sun's corona rather than forming later in interplanetary space, with researchers debating what the finding means for models of how the solar wind is heated and accelerated.
