Physicists undo the ‘coffee ring effect’
U. PENN (US) — By changing the shape of particles, physicists are able to disrupt a common phenomenon known as the “coffee ring effect“— the ring-shaped stain left after coffee drops evaporate. Continue…

Measuring matter hotter than the sun
VANDERBILT (US)—Scientists have created an exotic state of matter with a temperature of four trillion degrees Celsius. It’s the hottest temperature ever achieved in a laboratory and 250,000 times hotter than the heart of the sun. (more…)

High-speed images reveal essence of liquid
Simulation of a granular stream in free fall, breaking into particle clusters like droplets in a stream of water falling from a faucet. As in ordinary liquids, weak attractive forces drive the clustering, but result here in a novel, ultra-low surface tension fluid. (Credit: University of Chicago)

Dark energy model suggests frozen universe
VANDERBILT (US)—Imagine a time when the entire universe froze. According to a new model for dark energy, that is essentially what happened about 11.5 billion years ago, when the universe was a quarter of the size it is today. (more…)

Fine print so small it’s subatomic
STANFORD (US)—How tiny is the world’s smallest writing? The letters in the words written by Standford University researchers are assembled from subatomic-sized bits as small as 0.3 nanometers—or roughly one third of a billionth of a meter.
