Changing the antibiotic playbook to catch an ESKAPE artist‎

Nearly a century ago, a single colony of Staphylococcus aureus (S. aureus) helped launch the antibiotic age. In 1928, Alexander Fleming returned to his London lab to find that a stray mold had wiped out the Staphylococcus growing on one of his plates. The accident gave the world penicillin, ushering in the age of biomedicine and ensuring that an infected cut or scrape would not be fatal.

Early Earth's auroral belts may have formed a natural ion-beam reactor for prebiotic chemistry‎

We usually think of auroras as beautiful lights in the night sky. I see them as visible traces of a connection between the sun, Earth's magnetic field and the atmosphere. This led me to an origin-of-life question: Could the planetary structure that produces auroras also have organized chemical reactions on early Earth?

Crime is falling—but the public doesn't feel safer, UK study finds‎

Crime levels are falling for most offenses across the UK—but the public doesn't necessarily feel safer. It's a human trait to focus on frightening information in the news or on social media—but it could also mean that people are more fearful about crime than they need to be.

Park rangers and residents speak up to save Togo's last national park‎

A few years ago, I drove with an old friend from Togo, West Africa, towards the country's last remaining large protected area, Fazao-Malfakassa National Park. Our destination was the Hotel Fazao, where his uncle had once worked as a professional chef after its opening in 1980. For decades, while the park was managed by the Swiss Franz Weber Foundation (FWF), the hotel had hosted tourists from around the world who came to see elephants, monkeys, and other wildlife for which Africa is famous.

AI governance model inspired by Pope Leo XIV aims to put ethics first‎

Researchers at the John Paul II Catholic University of Lublin (KUL) and the University of Eastern Finland have developed a new model of artificial intelligence governance inspired by the teachings of Pope Leo XIV as set out in his encyclical Magnifica Humanitas. The new model is intended to ensure that AI technologies are developed and used safely, fairly and with full respect for human rights.

Bumpy battery surfaces can masquerade as nanoscale ion pathways, misleading material design‎

A signal that appears to show ions moving inside a battery may, in fact, be an illusion caused by an uneven surface. A KAIST research team has identified the origin of this type of artifact, which can lead researchers to misinterpret what is happening inside a battery, and has developed a method to reduce it.

War drama Pressure depicts D‑day's weather forecast—what we found when we recreated the challenge using modern systems‎

Meteorologist James Stagg gave what many regard as the most important weather forecast in history in June 1944. The fate of more than 150,000 Allied troops preparing to invade the Normandy beaches on D-Day and the future of the war in Europe depended on Stagg and his forecasting teams. Get the forecast wrong and an already perilous invasion might not succeed, prolonging the war. In the briefing room at Southwick House near Portsmouth, waiting for the forecast, sat General Dwight D. Eisenhower.

Survey of young researchers raises concerns over future of science in U.S.‎

One-third of young scientists who had been planning careers in academic research changed their minds in the spring of 2025, according to a new survey. Fewer expected to remain in higher education or work in the U.S., or felt that pursuing a Ph.D. was the right decision.
