The James Webb Space Telescope has captured a remarkably intimate portrait of two small galaxies locked in a slow, spiraling ...

ABSTRACT: As the foundation of the national economy, the stable and healthy development of agriculture is directly linked to sustained economic growth and long-term social stability. Strengthening the ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

We have long taken it for granted that gravity is one of the basic forces of nature—one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

‌A urine concentration test provides the specific gravity of your urine. This measures your kidneys’ ability to balance water content and excrete waste. It is important in diagnosing some health ...

All the fundamental forces are thought to be carried by a particle, but a new mathematical model suggests gravity may be a striking exception. Building on a decades-old idea, researchers have revealed ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

THE clinical value of the urinary specific gravity is unchallenged by the thousands who routinely perform it as part of every urinalysis. The claim that it differentiates transudate from exudate in ...
