Using an experimental technique called "Oz," researchers stimulated the human retina such that people saw a brand-new color.

Most gamers will focus on FPS as a gauge of performance. But monitoring this stat is even more important.

An 11-year Hubble study has finally revealed how long a day lasts on Uranus.

"I think that the simplest explanation of the rotating universe is the universe was born in a rotating black hole."

The familiar zodiac constellations are defined by Earth's motion around the sun, but they don't define your fate

The celestial equivalent to latitude and longitude lets astronomers find their way across the heavens

A 2022 image of our galaxy's central black hole taken with the Event Horizon Telescope could have some important inaccuracies, a new study claims.

A look at the inner workings of the famous fast voxel traversal algorithm.

We have been adding "leap seconds" to time kept by our atomic clocks, but soon we may have to subtract one. Are the tiny adjustments worth the bother?

Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with feature sizes ranging from several micrometers to hundreds of micrometers find intensive applications.

Using a phenomenon known as gravitational lensing, it might be possible to use the sun as a gigantic telescope to peer deep into space.

Sci-fi geeks rejoice!

The first materials scientists might have been early humans who—through trial-and-error experiments—discovered the first "cutting-edge" technologies. They found that the best arrowheads and other tools could be made from certain types of natural, structural materials, which at the time included stones and animal bones.

This paper describes a discrete state-space model -- and accompanying methods -- for generative modelling. This model generalises partially observed Markov decision processes to include paths as latent variables, rendering it suitable for active inference and learning in a dynamic setting. Specifically, we consider deep or hierarchical forms using the renormalisation group. The ensuing renormalising generative…

Researchers developed a machine-learning framework that can predict a key property of heat dispersion in materials that is up to 1,000 times faster than other AI methods, and could enable scientists to improve the efficiency of power generation systems and microelectronics.

Just 13.8 billion years after the hot Big Bang, we can see objects up to 46.1 billion light-years away. No, this doesn't violate relativity.

/PRNewswire-PRWeb/ -- PI, a global leader in nanopositioning and motion control, continues to contribute to space exploration advancement as PI 6-DOF hexapods...

For some reason, when we talk about the age of stars, galaxies, and the Universe, we use "years" to measure time. Can we do better?

A set of 632 main-belt asteroids (178 previously known and 454 unknown objects) has been identified in the archival images from the NASA/ESA Hubble Space Telescope.

Pluto's surface is dominated by the huge, pear-shaped basin Sputnik Planitia, which appears to be of impact origin, but modeling has not yet explained its peculiar geometry.
