The Earth's magnetic field has reversed many times at an irregular rate throughout its history. Long periods without reversal have been interspersed with eras of frequent reversals. What is the reason for these reversals ...
(Â鶹ÒùÔºOrg.com) -- 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 ...
(Â鶹ÒùÔºOrg.com) -- Â鶹ÒùÔºicists 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 ...
International collaboration including MPQ scientists sets a new value for the antiproton mass relative to the electron with unprecedented precision.
Supramolecules comprising many kinds of proteins and nucleic acids are present in all living organisms. Often with precise structures and a variety of parts, these supramolecules exhibit complex movements and exhaustive functions, ...
While insulating against electrical currents in their interior, the surface of materials called topological insulators permits the flow of electron spins relatively unhindered. The almost lossless flow of spin information ...
(Â鶹ÒùÔºOrg.com) -- The simplest, most sensible "Big Bang" universe, theoretical physicists believe, would be one in which equal numbers of particles and antiparticles are formed in pairs. As the universe cools, most of these ...
Nuclear magnetic resonance (NMR) is a powerful tool for chemical analysis and, in the form of magnetic resonance imaging (MRI), an indispensable technique for medical diagnosis. But its uses have been limited by the need ...
(Â鶹ÒùÔºOrg.com) -- In 1998, scientists discovered that the Universe is expanding at an accelerating rate. Currently, the most widely accepted explanation for this observation is the presence of an unidentified dark energy, ...
A new way of understanding the structure of proteins, polymers, minerals, and engineered materials will be published in the May 2011 issue of the journal Nature Materials. The discovery by two Penn State University researchers ...
