Various technologies, networks and institutions benefit from or require accurate time keeping to synchronize their activities. Current ways of synchronizing time have some drawbacks that a new proposed method seeks to address. ...
The so-called Doomsday Clock, created by the Bulletin of the Atomic Scientists to measure the imminent risk of nuclear conflagration, has been at 100 seconds to midnight since 2020. It's now looking increasingly out of time ...
Shine a flashlight into a murky pond water and the beam won't penetrate very far. Absorption and scattering rapidly diminishes the intensity of the light beam, which loses a fixed percentage of energy per unit distance traveled. ...
Scientists want to increase their understanding of circadian rhythms, those internal 24-hour biological clock cycles of sleeping and waking that occur in organisms, ranging from humans to plants to fungi to bacteria. A research ...
Attoclocks, or attosecond clocks, are instruments that can measure time intervals on the attosecond scale by measuring the time it takes for electrons to tunnel out of atoms. The attosecond procedure was first introduced ...
Atomic clocks are the best sensors mankind has ever built. Today, they can be found in national standards institutes or satellites of navigation systems. Scientists all over the world are working to further optimize the precision ...
Optical frequency combs have changed science and technology as we know it. Responsible for measuring things like infrared and ultraviolet light, greenhouse gases, atomic clocks, and disease, optical frequency combs act as ...
When we think of ions, we usually think of single atoms that have lost or gained some electrons, but entire molecules can also become ions. In a new publication that was highlighted as an Editor's Suggestion in Physical Review ...
Astronomers discovered the first exoplanets in 1992. They found a pair of them orbiting the pulsar PSR B1257+12 about 2,300 light-years from the Sun. Two years later they discovered the third planet in the system.
In a new study, Stanford researchers demonstrate how to manipulate atoms so they interact with an unprecedented degree of control. Using precisely delivered light and magnetic fields, the researchers programmed a straight ...
