Peppercorn-sized clumps of human brain cells grown in a lab for a record seven years aged similarly to those inside our heads, suggesting they "recorded the passage of time," scientists said Wednesday.

Humans develop at a slower rate than other mammalian species, like mice, but scientists are still trying to understand the molecular basis of these differences. Now, researchers from the Ebisuya Group at EMBL Barcelona and ...

The closer two people grow, the more alike their brains work—or so the assumption goes. Two ETH Zurich studies challenge this idea by examining the brain activity of younger and older adults who drew together over several ...

Superconductors are materials that carry electrical current with zero resistance below a specific critical temperature. In conventional superconductors, the transition to superconductivity generally occurs at very low temperatures.

Electron microscopes are used wherever particularly small details need to be imaged. But from a strictly physical point of view, every electron in a conventional electron microscope represents a missed opportunity: If all ...

Blue morpho butterflies have captivated the human eye for centuries. We even have one as an emoji on our phones. In a recent experiment, researchers at the Smithsonian Tropical Research Institute (STRI) documented for the ...

A global symbol of parties and celebrations but an environmental headache, the humble balloon is undergoing a green revolution thanks to U.K. researchers.

More than 6,500 years ago, someone carefully drilled a hole in a human tooth, strung it on a cord and likely used it as a necklace. Found during field surveys at the Vinča cultural site of Jablanica in Serbia, the human tooth ...

Precise activation of tens of thousands of genes is critical for healthy development and growth. Specialized segments of our DNA are responsible for carefully orchestrating genetic sequences that result in the production ...

Ammonia is one of the most important chemicals produced in the world, ranking second only to sulfuric acid in the total volume produced each year. It is used mostly to make fertilizer, which is essential to feeding the world's ...

Now it's the moon's turn to pull a disappearing act. After being shut out of this month's total solar eclipse, the Americas will have the best seats in the celestial house when Earth's shadow briefly envelops the moon. Almost ...

A human, an octopus, and a coral could hardly look more different—yet deep inside their cells, their chromosomes still carry recognizable pieces of a genome inherited from an animal ancestor that lived more than 600 million ...
