Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Frequency Analysis of Hard Disk Drive Spindle System Supported by Hydrodynamic Bearings

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2007
Herringbone-grooved hydrodynamic bearings are now being applied to hard disk drive (HDD) spindle motors instead of ball bearings for demand for HDDs with larger storage capacities, faster access times, and reduced sizes.

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
