Nuclear clocks tick for the first time

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca Toscani De Col and colleagues ...

Slime molds make decisions using internal fluid flows

Despite lacking brains or nervous systems, slime molds are capable of making surprisingly sophisticated decisions: navigating mazes, finding food and even remembering where they found it last time. How they manage to do all ...

New strategy enhances oxygen reduction in zinc-air batteries

Batteries are undergoing rapid advances. For example, modern zinc-air batteries have the remarkable ability to use oxygen as energy—but that oxygen isn't stored in the battery itself. Zinc-air batteries take in surrounding ...

Our brains may be automatically filtering out negative words

We tend to assume that emotionally charged words are more likely to grab our attention. An insult shouted across a crowded room or a disturbing phrase overheard on television can seem impossible to ignore. But a new study ...

Fructose sends a weaker satiety signal to the brain than glucose

Researchers at the Monell Chemical Senses Center have found that common dietary sugars fructose and glucose, despite having the same number of calories, communicate with the brain through different gut–brain pathways, a difference ...

Trees may store less carbon than expected in the future

It's intuitive to think that if a tree is photosynthesizing, it's also growing. But that's not necessarily so—and a new study of oak trees, published in the journal Science Advances, found that even as they photosynthesize ...

Supercomputer predicts 2026 World Cup results

A model built by researchers from the University of Liverpool's Management School predicts an England-Spain FIFA World Cup 2026 final, with Spain the favorite to lift the trophy—a repeat of recent major tournament history. ...

SpaceX lifts off in record Wall Street debut

Elon Musk's SpaceX began its first day as a public company on Wall Street on Friday after the biggest initial public offering in history, with the polarizing entrepreneur promising he will take humanity to Mars.
