When Einstein's gravitational waves meet Newton's tides
Newton's theory of gravity has described the tides accurately for centuries. But could a tiny trace of Einstein's general relativity also be hidden in them? In...
NASA's Swift telescope has burned up, months after a robot sent to save it failed
NASA's Neil Gehrels Swift Observatory took its last look at the sky on Oct. 20, 2026, while orbiting about 171 miles (275 kilometers) above Earth. NASA ended th...
Earth's slowing spin may have shaped its primordial crust
Around 4.5 billion years ago, a planet-sized object collided with the newly formed Earth, throwing out the debris that would later form the moon. The collision...
From doctors and teachers to lawyers, every profession has a duty to align with climate goals
A Dutch family doctor named Tibor Poelmann posted a petition on an online forum for general practitioners (GPs) in 2021. He wanted their pension fund to stop in...
Coordinated activity gives large pedestrian crowds a distinctive seismic signature
Large pedestrian crowds generate distinctive seismic signals depending on their collective behavior, according to a new study that includes data from Tokyo scho...
Young children like sharks, but fear grows with age
Most young children like sharks, with almost seven in 10 describing them in a positive light, but a new study has found that associations between sharks and fea...
Which infinity is bigger? Under alternative mathematical rules, a 2D map emerges
It is one of the great questions of mathematics: What does "infinity" actually mean? Which infinities are larger than others? Can infinities be arranged in a se...
New statistical method eliminates AI estimation bias in econometrics
A new research paper describes a statistical framework that resolves significant calculation biases caused by artificial intelligence in econometric models. The...
What sorts of nudges win wallet share in the attention economy?
Nudges—the subtle interventions that encourage people to make beneficial decisions without forcing them into these choices—are a popular marketing tool widely u...
Microbial growth in simulated Mars conditions could guide search for life
A new experiment reveals that Earth's microbes can grow in harsh conditions similar to what may exist just below the surface of Mars, suggesting new directions...
Researchers highlight ferroptosis's dual roles in plant immunity
When plants encounter pathogens, they can defend themselves by rapidly killing infected cells to restrict pathogen spread. This immune response, known as the hy...
A phenanthrene co-guest helps crystalline sponges reveal 3D structures of small, low-polarity molecules
Adding phenanthrene as a co-guest let the second-generation crystalline sponge (2G-CS) method determine X-ray structures for 24 of 30 small, low-polarity C₁₅ mo...
