Humans develop sharp vision during early fetal development thanks to an interplay between a vitamin A derivative and thyroid hormones in the retina, Johns Hopkins University scientists have found.

In this quick science experiment, I fill a bowl with clear water beads and show how they seem to disappear when I pour in ...

When light passes through materials, it typically changes direction and bends in predictable ways. This change in direction, known as refraction, is caused by a change in the speed of light as it ...

In the 1930s, the Switzer brothers stumbled onto a way to mimic fluorescence. That led to Day-Glo, which has been making the world a brighter place ever since ...

Physicists artificially slowed down time to reveal the bizarre Terrell-Penrose effect, a consequence of special relativity. This image from the experiment shows a sphere seemingly moving at 99.9 ...

Since it turned on, the James Webb Space Telescope has revealed dozens of mysterious red blobs in space. The so-called Little Red Dots start to appear around 600 million years after the big bang and ...

Achieving sub-second 3D printing, DISH combines wave-optics modeling and angular illumination to improve resolution and depth in additive manufacturing.

have created a new type of insect cyborg that can navigate autonomously -- without wires, surgery, or stress-inducing electrical shocks. The system uses a small ultraviolet (UV) light helmet to steer ...

Adam Sherwinski teaches ciLiving host, Jaclyn Friedlander about light refraction. Watch how light bends when it passes ...

A doctoral student re-created a tiny piece of the universe in a bottle to investigate the chemistry that led to life on Earth.

A team of scientists led by Academician Professor Xiang Zhang, President and Vice-Chancellor of The University of Hong Kong ...

Artemis II, the next mission in NASA’s Artemis program to explore the Moon, is scheduled to launch from Florida within the coming weeks. The mission will be the first crewed mission to the vicinity of ...
