Editor’s note: On November 17, 2022, Science retracted the study described in this article, in part because “an analysis of the raw and published data revealed serious irregularities and discrepancies,” writes H. Holden Thorp, the editor in chief of Science. “These issues have caused the editors at Science to lose all confidence in the conclusions […]
Like the surface of an alien planet, thin sheets of copper display a complex topography of ridges and valleys. These never-before-seen undulations may spell trouble for electronic gadgets: The zigzagging surface could contribute to the electrical resistance of miniature copper wires that snake throughout computer chips. Using a scanning tunneling microscope, scientists observed nanoscale peaks […]
Diamonds are going 2-D. The superhard form of carbon can be forged in thin films known as diamondene, new evidence suggests. While graphite, the form of carbon found in pencils, can be made into atom-thick sheets known as graphene, scientists have struggled to create two-dimensional films of its relative, diamond. When a pair of graphene […]
If Lewis Carroll were alive today, he wouldn’t bother with a looking glass. His book would be called Alice Through the Wormhole. Being the mathematician that he was, Carroll (aka Charles Dodgson) would have kept current with the latest developments in quantum physics. He would no doubt be intrigued by a new paper describing an […]
The sky will go dark. The temperature will drop. Stars will shine in the middle of the day. For the first time in nearly a century, millions of Americans from coast-to-coast will witness a total solar eclipse. Those who have watched the sun suddenly snuff out say it’s an otherworldly feeling. It can be humbling. […]
CASPER MOUNTAIN, Wyo. — It’s nothing like a sunset. It’s cold and dark, but it’s not like nighttime, or even twilight. The moon just snaps into place over the last slivers of the sun, turning the sun into a dark hole. The only illumination — a flat, ghostly, metallic sort of light — is from […]
Dumb extinction jokes aside, dodos’ life history is largely unknown. Now the first closeup look inside the long-gone birds’ bones is giving a glimpse into their lives, an international research team reports August 24 in Scientific Reports. Until now, almost nothing has been known about the basic biology of dodos, such as when they mated […]
A newfangled data storage device, which takes up less than a millionth the amount of space of its predecessors, could be a key component of futuristic communication systems. Scientists fashioned a tiny crystal that stores snippets of quantum information — which unlike computer data “bits” that come only in 0s and 1s, can also exist […]
In the Twitterverse, science can stir up some vigorous debates. And they’re not all about the standard issues of climate change, vaccines and evolution. Some dueling tweets involve the scientific enterprise itself. For instance, one recent tweet proclaimed “Science isn’t ‘self-correcting.’ Science is broken,” linking to a commentary about the well-documented problem that many scientific […]
A series of rapid-fire solar flares is providing the first chance to test a new theory of why the sun releases its biggest outbursts when its activity is ramping down. Migrating bands of magnetism that meet at the sun’s equator may cause the biggest flares, even as the sun is going to sleep. A single […]
