Sodium-ion batteries are attracting growing attention as a greener and more affordable alternative to today’s lithium-ion batteries. Sodium is abundant, widely available, and cheaper than...

After a nuclear or radiological accident, knowing who has been exposed to radiation—and how much—can save lives. But traditional ways of measuring radiation dose usually...

More than 200 years after Johann Wolfgang von Goethe’s death, his curiosity about nature is still leading to new discoveries. Scientists in Germany have now...

The chemical is known as thiepine, or 2,5-cyclohexadiene-1-thione (C₆H₆S), a ring-shaped sulfur-bearing hydrocarbon produced in biochemical reactions. When examining the molecular cloud G+0.693–0.027, a star-forming...

Scientists have created the most detailed map yet of dark matter—the mysterious substance that makes up most of the universe and quietly shapes everything...

Breast cancer is one of the most common cancers among women worldwide. For decades, mammography screening has been one of the most important tools...

Physicists at Heidelberg University have developed a new theory that brings together two long-separate ideas in quantum physics, offering a clearer picture of how...

Quantum materials sound futuristic — their strange behaviors come directly from the laws of quantum physics, which govern how atoms and electrons interact. They can...

In 2023, NASA's OSIRIS-REx mission returned a sample of dust and rocks from the near-Earth asteroid Bennu. This remarkable achievement not only provided scientists with...

In a new study, researchers found that the highly-infectious SARS-CoV-2 virus is most ideally adapted to infect human cells—rather than bat or pangolin cells In...

As electric vehicles and renewable energy systems become more common, the world is searching for better, more affordable, and environmentally friendly battery options. A new...
