Experimental setup A detailed description of our experimental setup has been given in previous works35,60,61. In short, we trap individual 88Sr atoms in a programmable one-dimensional array of optical tweezers (813 nm) generated by acousto-optic deflectors (AODs). The atoms are initialized in the 5s2 1S0 state and cooled on the narrow-line red transition 5s2 1S0 ↔ 5s5p 3P1
Two US Army 4th Infantry Division soldiers sat on the barren desert earth at Fort Irwin, California. One wore first-person-view goggles and held a drone controller. The other watched the drone’s feed on a laptop. After a few moments of setup, the Neros Archer lifted off, the buzz loud up close and still audible at
Explanation: There are more than half a million galaxies in the central panel of this image from the NSF-DOE Vera C. Rubin Observatory in Chile. This is the COSMOS field, a patch of sky several times larger than the full moon, first observed by Hubble. It has also been observed by Webb and other telescopes because it contains comparatively few bright stars from our own galaxy, offering
U.S. Immigration and Customs Enforcement says it expects every officer and agent in the field to be equipped with a body camera by the end of August, a rapid expansion that could provide an unprecedented visual record of the federal government’s immigr… WASHINGTON — U.S. Immigration and Customs Enforcement said Saturday it expects every officer

When NASA’s Curiosity rover recently began ascending a Martian valley nicknamed “Big Valley,” it sent back images that were familiar to scientists on the mission: honeycomb textures called polygonal fractures, each about 1.5 to 3 inches (4 to 8 centimeters) wide. The mission has detected small specks of these geometric shapes several times before, but
