he movements of cilia and flagella are driven by axonemal dynein ATPases, whose activity must be coordinated in space and time. On page 47, Rupp and Porter provide the first molecular characterization of a component of the dynein regulatory complex (DRC), a crucial but poorly understood regulator of flagellar movement. Besides suggesting a model for DRC assembly, the work identifies a possible ...

Abstract The pairing correlation in nuclei causes a characteristic excitation, known as the pair vibration, which is populated by transfer reactions. Here we introduce new method of characterizing vibration employing an analogy to Higgs mode, emerges infinite superconducting/superfluid systems collective vibrational mode associated with amplitude oscillation Cooper condensate. idea formulated d...

Leakage of air in tumble dryers is an important parameter regarding the energy efficiency drying process. In general, are prone to leakage, therefore further investigation and optimization this field great interest. This study investigates quantifies leakage within closed-loop system in-situ household heat pump dryer. Each potential location was characterized by curve obtained either isolated o...

Using magnetic tweezers, we study in real time the condensation of single DNA molecules under tension. We find that DNA condensation occurs via discrete nucleated events. By measuring the influence of an imposed twist, we show that condensation is initiated by the formation of a plectonemic supercoil. This demonstrates a strong interplay between the condensation transition and externally impose...
