Patterns of noise—normally considered flaws—in images of an ultracold cloud of potassium provide the first-ever visual evidence of correlated ultracold atoms, a potentially useful tool for many applications, according to physicists at JILA.
A virtually unstoppable 'snakebot' developed by a University of Michigan team resembles a high-tech slinky as it climbs pipes and stairs, rolls over rough terrain and spans wide gaps to reach the other side.
Taking a new approach to the painstaking assembly of nanometer-sized machines, a team of scientists at the University of Wisconsin-Madison has successfully used single bacterial cells to make tiny bio-electronic circuits.
President Bush presented medals today to eight scientists and engineers, including two Nobel laureates, for their distinguished careers and lifelong and individual achievements.
Thirty-five years after Moon-walking astronauts placed special reflectors on the lunar surface, scientists have used these devices to test Albert Einstein's general theory of relativity to unprecedented accuracy.
Using a technique employed by astronomers to determine stellar surface temperatures, chemists at the UIUC have measured the temperature inside a single, acoustically driven collapsing bubble.
A full-scale quantum computer could produce reliable results even if its components performed no better than today’s best first-generation prototypes, according to a paper in the March 3 issue in the journal Nature by a NIST scientist.
Data from the Cassini-Huygens satellite showing oxygen ions in the atmosphere around Saturn's rings suggests once again that molecular oxygen alone isn't a reliable indicator of whether a planet can support life.
'He who finds a thought that lets us even a little deeper into the eternal mystery of nature has been granted great grace.'
