Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

A team of scientists has replicated one of Thomas Edison's early experiments from his quest to make the lightbulb, but with ...

Experiments with identical replicas of Thomas Edison's original light bulbs shows the inventor may have accidentally created ...

A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with ...

In this video I test if light can be black. I show you several experiments that show you cases of light that is black and ...

Much of what we know about plant circadian rhythms is the result of laboratory experiments where inputs such as light and temperature can be tightly controlled. Less is known about how these ...

Researchers discovered that light can cause evaporation of water from a surface without the need for heat. This 'photomolecular effect' could be important for understanding climate change and for ...

Green light means “go.” That might apply to evaporating water molecules too. Visible light, especially that of a greenish hue, might spur water to evaporate, researchers report in the Nov. 7 ...

Biologist Brian Gall was flinging stowaway spiders out of his kayak when he noticed an interesting pattern: After landing on the water’s surface, the arachnids quickly darted to the nearest shoreline, ...
