For the first time, NASA's TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting ...
A new big-data analysis of the U.S. pinpoints how urban design aids the health of city residents—especially when cities provide walking opportunities, greenery and mixed-use streets with a blend of ...
A new evolutionary theory suggests that some asexual parasites may temporarily be able to infect a wider range of hosts as harmful genetic mutations build up. In a paper published in Trends in ...
Scientists have engineered a nanoscale switch using DNA "origami." Inspired by macroscale mechanical switches, the device achieves long-term functionality without the continuous forcing mechanism that ...
As humans, our eyes take in two-dimensional images that our brains convert to three-dimensional experiences. This ability enables us to be aware of our position in space, judge distances, possess ...
Imagine a piece of space debris the size of a hockey puck slams into a Starlink satellite at about 10 kilometers per second. The kinetic energy is equivalent to 2 kilograms of TNT, or a fully loaded ...
Before a leaf dies, plants recover nutrients that the rest of the plant can reuse for growth and survival. Researchers at Umeå Plant Science Center have now identified a metabolic "point of no return" ...
The growing use of renewable energy sources, such as solar and wind power, requires energy storage systems that can charge quickly, deliver power efficiently and remain stable over long-term use.
