Sperm cells
// Journal Covers
Nanoscale mechanical forces generated by axonemal dynein motors derived from sperm flagellum are examined and reported.
Molecular model, hands
// Journal Covers
Analysis of molecular dynamics simulations shows that although the opened form of Proliferating Cell Nuclear Antigen (PCNA) can achieve conformations matching the helical pitch of Replication Factor C, it is not biased toward a right-handed spiral structure.
Images of spores
// Journal Covers
Preparation and sectioning of bacterial spores by focused ion beam and subsequent high resolution secondary ion mass spectrometry analytical imaging is demonstrated.
Images of optical damage
// Journal Covers
In this study, we quantitatively compare the effectiveness and efficiency of mid-IR (4.6 μm) versus far-IR (10.6 μm) lasers in mitigating damage growth on fused silica surfaces.
