The Sun released a powerful X1.3-class solar flare on the afternoon of July 4, peaking at 4:41 p.m. Eastern Time (20:41 UTC), NASA’s Solar Dynamics Observatory confirmed. The flare originated from a newly emerged sunspot region designated AR4482 on the Sun’s southeast limb. X-class flares are the most intense category on the solar flare scale, […]

Philosophy journals have no uniform conflict-of-interest policies. A researcher can publish a paper on AI ethics while serving as a paid consultant for an AI company, and readers, and editors, would have no structured way to know. A new open letter released July 1 by professors Cailin O’Connor (UC Irvine) and Craig Callender (UC San […]

For twenty years, computer scientists have wrestled with a deceptively simple question: can a quantum computer verify solutions to problems that a classical computer cannot even describe? The answer, it turns out, is yes, and the proof is 96 pages long. A team of four researchers, John Bostanci (Simons Institute / Columbia), Jonas Haferkamp (Ruhr […]

The booming market for online GLP-1 prescriptions is built on convenience: a few clicks, a brief questionnaire, and a month’s supply of a weight-loss drug arrives at your door. But a new secret shopper study published July 6 in JAMA reveals how little clinical oversight many of those prescriptions involve. Researchers at Yale University posed […]

Psoriasis affects more than 125 million people worldwide, and while biologic therapies that block the IL-17 pathway have transformed treatment, they remain expensive, require injection, and suppress the immune system systemically. A new study published in Nature Communications on July 6 opens the door to a different approach: topical creams that achieve the same effect […]

Heart failure with reduced ejection fraction (HFrEF), a condition in which the heart’s left ventricle cannot pump blood effectively, remains a major therapeutic challenge despite advances in drug therapy. Researchers at Harbin Medical University have identified a molecular mechanism that drives the pathological cardiac remodeling at the root of the disease: a splicing factor called […]

Modeling extreme weather events, the kind that cause the most damage, is computationally brutal. A 1-in-100-year heatwave requires at least 100 simulated years to generate even a single example by brute force. With high-resolution climate models, the computing time and energy cost associated with such a simulation would be measured in months or years, even […]

The first real-world field test of a geoengineering concept to slow Arctic sea ice loss has produced a clear result: pumping seawater onto the surface of sea ice can thicken it by up to 32 centimeters. The question is whether the approach can ever work at a meaningful scale. The experiment, conducted during the 2024-2025 […]

For more than a century, physics textbooks have taught that magnets come in two fundamental types. Ferromagnets, like the bar magnets on a refrigerator, have a strong net magnetization because all their atomic spins point in the same direction. Antiferromagnets have their spins arranged in alternating opposite directions, canceling out to produce zero net magnetization. […]
