Es gibt Suppenkasper, Korinthenkacker oder trübe Tassen. Man kann etwas anbrennen lassen, viel versieben und sogar den Löffel abgeben. Die Küche ist ein Ort der Sprüche. Welche kennen Sie?
Überraschende Entdeckung im Amazonas-Urwald: Offenbar lebt dort eine Affenart, die Biologen bisher verborgen geblieben war. Doch die Freude ist getrübt, denn der kleine Springaffe ist vom Aussterben bedroht.
J. C. Martinez, M. B. A. Jalil, and S. G. Tan The Klein tunneling of charge pairs in an electrostatically created p-n junction of monolayer graphene is shown to occur at an observable rate for moderate fields. The pairs undergo zitterbewegung (ZBW) in opposite directions leading to their separation and transverse dipole moment, since the valley ... [Appl. Phys. Lett.
Yu. Kaganovskii, D. L. Beke, and S. Kokenyesi The kinetics of photoinduced variations in surface profile in chalcogenide glass films under illumination is described. It is demonstrated that the competition between the stress-induced atomic flux (toward irradiated regions of the film) and the diffusion flux induced by an increase in the bulk ene ... [Appl. Phys. Lett.
Gian Luigi Bendazzoli, Stefano Evangelisti, Antonio Monari, and Raffaele Resta The qualitative difference between insulators and metals stems from the nature of the low-lying excitations, but alsoaccording to Kohn's theory [W. Kohn, Phys. Rev. 133, A171 (1964)]from a different organization of the electrons in their ground state: electrons are localized in insulators and deloca ... [J. Chem.
D. R. Welch, D. V. Rose, C. Thoma, R. E. Clark, C. B. Mostrom et al. Fully kinetic simulations have demonstrated that at sufficiently high currents, half of the neutrons produced by a deuterium Z-pinch are thermonuclear in origin. At 150-kA pinch current, O. A. Anderson et al. [Phys. Rev. 110, 1375 (1958)] clearly shows that essentially all of the neutrons produced b ... [Phys.
J. H. Gurian, H. Maeda, and T. F. Gallagher We have electro-optically sliced the output light of a commercial Coherent Evolution Nd:YLF laser to pump a kilohertz repetition rate nanosecond dye laser system. Simple and highly adjustable, this laser system can easily be used for initial state preparation for ultrafast systems as well as high re ... [Rev. Sci. Instrum.
In a new regime for atomic clocks, strong interactions between atoms dramatically increase the clock’s coherence time.

Background:
Classical nuclear localization signal (NLS) dependent nuclear import is carried out by a heterodimer of importin α and importin β. NLS cargo is recognized by importin α, which is bound by importin β.
Mutations of the KCNJ10 (Kir4.1) K+ channel underlie autosomal recessive epilepsy, ataxia, sensorineural deafness, and (a salt-wasting) renal tubulopathy (EAST)...
