What time is it? The answer, no matter what your initial reference may be—a wristwatch, a smartphone, or an alarm clock—will always trace back to the atomic clock.
(Phys.org) —Within the mammalian inner ear, or cochlea, a remarkable but and long-debated phenomenon occurs: As they move from the base of the cochlea to its apex, traveling fluid waves – that is, surface waves, in which ...
(Phys.org) —Not all water is equal—at least not at the molecular level. There are two versions of the water molecule, para and ortho water, in which the spin states of the hydrogen nuclei are different. In the journal Angewandte ...
(Phys.org) —As computer chips continue to get smaller and more powerful, the field of electronics is approaching some severe limits.
Where did life on Earth come from? There are several theories as to what might have happened. Maybe comets came bearing organic material, or life was transported from another planet such as Mars, or something happened in ...
When a two-body relation becomes a three-body relation, the behaviour of the system changes and typically becomes more complex. While the basic physics of two interacting particles is well understood, the mathematical description ...
(Phys.org) —A chip-scale device that both produces and detects a specialized gas used in biomedical analysis and medical imaging has been built and demonstrated at the National Institute of Standards and Technology (NIST). ...
Carbon nanotubes are expected to be used in a myriad of applications ranging from military protective clothing to hydrogen storage. Due to their nanometer dimensions, however, the structure and surface chemistry of individual ...
Fungal geneticist Scott Baker rifles through a stack of petri dishes housed in a small refrigerator at EMSL. He selects a plate dotted with white cauliflower-shaped colonies of fungus, punctuated by one brazen smudge that ...
(Phys.org) —Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a compact atomic clock design that relies on cold rubidium atoms instead of the usual hot atoms, a switch that promises ...
