Time reversal: A simple particle could reveal new physics
A simple atomic nucleus could reveal properties associated with the mysterious phenomenon known as time reversal and lead to an explanation for one of the greatest mysteries of physics: the imbalance of matter and antimatter in the universe. The physics world was rocked recently by the news that a class of subatomic particles known as […]
New twist on Brownian motion seen for the first time
October 11, 2011
An important aspect of Brownian motion predicted decades ago has been observed for the first time by researchers in Europe. The team has measured how micrometre-sized spheres interact with a surrounding fluid and have shown that the spheres “remember” their previous motion. Their experimental technique, the researchers claim, could be used as a biophysical sensor. […]
Physicists turn liquid into solid using an electric field
October 11, 2011
Physicists have predicted that under the influence of sufficiently high electric fields, liquid droplets of certain materials will undergo solidification, forming crystallites at temperature and pressure conditions that correspond to liquid droplets at field-free conditions. This electric-field-induced phase transformation is termed electrocrystallization The study, performed by scientists at the Georgia Institute of Technology, appears online […]
How a Team of Enthusiasts Are Mapping Dark Matter
October 11, 2011
Earthly skills like handwritten signature verification turn out to be useful on a cosmological scale as well When the Euclid mission lifts off at the end of this decade, it will map galaxy clusters in infrared and visible light, helping to blueprint the large-scale structure of the universe. And a bunch of amateur science geeks […]
The microwave sky after one year of Planck operations
October 11, 2011
Aniello Mennella, for the Planck Collaboration The ESA Planck satellite, launched on May 14th, 2009, is the third generation space mission dedicated to the measurement of the Cosmic Microwave Background (CMB), the first light in the Universe. Planck observes the full sky in nine frequency bands from 30 to 857 GHz and is designed to […]
