In a lab in Zurich, scientists have built something that, at first glance, shouldn’t be possible. When a beam of infrared light strikes their ultra-thin lens—barely thicker than a red blood cell—it ...

Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and optical sensing. Ultraviolet and near-infrared wavelengths are routinely ...

A team of scientists has developed a powerful new way to detect subtle magnetic signals in common metals like copper, gold, and aluminum—using nothing more than light and a clever technique. Their ...

Scientists have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems. Scientists from the University of Birmingham and the University of Cambridge ...

Light painting is a technique used in both art and science that involves taking long-exposure photographs while moving some kind of light source—a small flashlight, perhaps, or candles or ...

Light pollution is a newly recognized source of pollution with many complexities. What is light pollution to one person may be the desired light levels of another. Balancing the pros and cons of light ...

A giant object that has been lurking in the relative galactic vicinity of the Solar System this entire time has just been unmasked in all its enormous, invisible glory. Just 300 light-years away, at ...

Scientists have introduced a microscopy technique that reveals a hidden layer of chemistry involving molecules that normally ...

Light and space artist Helen Pashgian's translucent columns seem like swollen sea creatures of the deep, ghostly structures that glow in darkened spaces. For about two years, Pashgian has been ...
