Scientists reach the ultimate quantum limit on a surface

Scientists have achieved a quantum breakthrough by creating an ultra-clean surface where individual molecules can maintain their delicate quantum properties at the fundamental limit. The discovery could unlock unprecedented control over molecules and help drive the next generatio

Alaska’s monster tsunami sent water 1,580 feet up a mountain

A massive landslide in Alaska triggered the second-highest tsunami ever recorded, sending water and debris 1,580 feet up a mountainside just hours after tourists visited the area. Scientists discovered that the disaster was preceded by several warning signs, including rapid glaci

Metalens microscope switches focus with voltage, not moving optics

Just as it is difficult for a camera to keep both a nearby flower and a distant mountain sharply focused at the same time, conventional optical microscopes face a similar challenge when imaging structures located at different depths inside the body. Tighter focusing of light impr
