Optogenetics has long been a powerful experimental tool, but a growing body of research suggests it may now be approaching a ...

Light can do more than illuminate a material. In some cases, it can temporarily change how electrons move through it. That ...

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 ...

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 ...

The film explores the properties of light, including reflection and refraction, through various experiments. It demonstrates how light travels in straight lines, how mirrors can reflect images, and ...

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 ...

The process that powers much of life on Earth, photosynthesis, is so finely tuned that just one photon is enough to kick it off. Scientists have long suspected that photosynthesis must be sensitive to ...

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, ...
