Most conventional methods of ultrafast photography use evenly spaced intervals in which images are taken, but new developments have shown how much can be left out of the story, especially when multiple timescales are involved.
Light is one of the most powerful tools scientists have for probing matter. By interacting with electrons, light reveals how atoms, molecules and materials are structured and how they evolve in time. Highly energetic ultraviolet ...
Tiny atoms and molecules are constantly bombarding each other all around us. While we regularly measure the large-scale effects of these interactions, measuring the effect of each individual collision is far more difficult. ...
Drone-mounted laser technology is helping archaeologists locate Aboriginal rock art sites hidden in the rugged, densely vegetated landscapes of Australia's Blue Mountains, demonstrating a new approach to surveying archaeological ...
It looks like a small, transparent patch with a rainbow on its surface—or for those old enough to remember, the back of a CD. The patch is the first of its kind in the world and, when combined with an ordinary smartphone ...
In a new Nature Physics study, researchers found that fin regrowth in zebrafish is driven by a brief burst of growth signal at the fin tip, sized to the amount lost, which sets up gradients of Erk activity that guide the ...
Voltage fluctuations, light fluctuations, temperature fluctuations—any fluctuations are troublesome and thus undesirable. They don't just cause discomfort; in engineering and medical applications, they affect the accuracy ...
The Korea Research Institute of Standards and Science (KRISS) has remeasured a key transition frequency of the strontium (Sr) atom for the first time in 88 years, since 1938, using a photonic grating chip. It has established ...
Today's computer technology, based on silicon chips, is slowly reaching its physical limits. Components cannot be miniaturized indefinitely, and clock speeds cannot be increased indefinitely. At the same time, huge AI data ...
Some quantum systems are so complex that even the most powerful supercomputers struggle to simulate their behavior. One solution is quantum simulation: building a controllable quantum system in the lab and tuning it to mimic ...
