Experiments at Lawrence Livermore National Laboratory's National Ignition Facility (NIF) require breathtaking precision. Each of the 192 lasers is focused to a width of a few millimeters to enter a 3-millimeter hole at the top or bottom of a 2-centimeter (0. 8-inch) gold canister known as a hohl...
After his wife’s death while doing fieldwork, he rejected writing as a detached observer, setting off a profound shift in cultural anthropology.
Half of all Americans live in the suburbs. For decades, planners and policymakers have blamed suburban sprawl's environmental and social costs on one thing: distance. The farther people live from city centers, the more they drive, the more carbon they emit and the more disconnected they become ...
Global climate change has increased the frequency of regional cold spells, causing substantial yield losses and even crop failure. Meanwhile, excessive nitrogen fertilizer use in agriculture has increased non-point-source pollution. Improving both stress resilience and nitrogen use efficiency h...
Southwest Research Institute (SwRI) scientists studying the inner main-belt asteroid Donaldjohanson have found that its rotation wobbles. Rather than rolling through space in a steady pattern, Donaldjohanson turns on two axes, rotating end over end once every 10. 5 Earth days while wobbling arou...
How does light turn into motion within a metal? A team of researchers from European XFEL, the University of Potsdam and other participating institutions has shown that ultrashort optical laser pulses can trigger extremely rapid lattice vibrations in periodically layered metal structures—not prim...
