After a quiet, six-and-a-half-year, 2.2-billion-mile journey to Saturn aboard NASA’s Cassini spacecraft, the University of Chicago’s dust detector will soon begin its attempt to help unravel the mystery of the planet’s legendary rings one tiny particle at a time.
Cassini will become the first spacecraft ever to enter Saturn’s orbit at precisely 9:30 p.m. CDT June 30. NASA launched Cassini in October 1997. The University’s instrument, called the High Rate Detector, has quietly recorded sporadic dust impacts in interplanetary space during the mission. "We have seen some impacts, but only a few, maybe one a month. That’s about all you’d expect," said Anthony Tuzzolino, a Senior Scientist at the University of Chicago’s Enrico Fermi Institute.
But that could change on June 30, after Cassini passes through a gap between two of Saturn’s rings. The rings consist of billions of objects ranging in size from microscopic particles to car-sized boulders locked into orbit around the planet.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
