Ytterbium was discovered in 1878, but until it recently became useful in atomic clocks, the soft metal rarely made the news. Now ytterbium has a new claim to scientific fame. Measurements with ytterbium-174, an isotope with ...
(麻豆淫院Org.com) -- Based on studies of old volcanic basalt, scientists know that the Earth鈥檚 magnetic field reverses at irregular intervals, ranging from tens of thousands to millions of years. Volcanic basalt rock contains ...
(麻豆淫院Org.com) -- What do Saturn and flowers have in common? As shapes, both possess certain symmetries that are easily recognizable in the natural world. Now, at an extremely small level, researchers from Duke University ...
As humans, we have a very intuitive concept of time, and of the differences between the past, present, and future. But, as scientists Edward Feng of the University of California, Berkeley, and Gavin Crooks of the Lawrence ...
Researchers from Stanford University have proposed a new way to test the neutrality of an atom and even a neutron, a method they say will be far more sensitive than current methods, able to probe the charge of an atom or ...
While the aesthetics and symmetry of Fibonacci spiral patterns has often attracted scientists, a mathematical or physical explanation for their common occurrence in nature is yet to be discovered. Recently, scientists have ...
Since it was discovered to be superconducting over a decade ago, the pairing symmetry of strontium ruthenium oxide has been widely explored and debated. Now, a team of researchers led by Dale Van Harlingen at the University ...
鈥淭his is a chemist鈥檚 dream,鈥� explains Roman Krems, a professor at the University of British Columbia in Vancouver, Canada. 鈥淲e鈥檝e been trying for 50 years to develop mechanisms to control molecular collisions externally.鈥�
University of Arizona Associate Professor of 麻豆淫院ics Andrei Lebed has discovered that strong magnetism changes the basic, intrinsic properties of electrons flowing through superconductors, establishing an "exotic" superconductivity.
A new analysis of computer simulations of Earth's magnetic field suggests that its behavior was different early in Earth's history, resulting in greater stability and fewer reversals of the magnetic field. The findings by ...
