The chemical and structural organization of the plant cell wall was examined in Zinnia elegans tracheary elements (TEs), which specialize by developing prominent secondary wall thickenings underlying the primary wall during xylogenesis in vitro.
We report an attosecond pump–probe measurement of the density matrix of valence electrons in atomic krypton ions.
Nanoscale mechanical forces generated by axonemal dynein motors derived from sperm flagellum are examined and reported.
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.
Preparation and sectioning of bacterial spores by focused ion beam and subsequent high resolution secondary ion mass spectrometry analytical imaging is demonstrated.
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.
In September 1981, legendary astronaut and first man on the moon Neil Armstrong visited Lawrence Livermore National Laboratory for the filming of a TV documentary on the U.S.
In February 1965, Apollo astronauts paid a visit to the pockmarked desert of the Nevada Test Site as part of their lunar training.
On July 6, 1962, the Sedan Event, the largest of the Project Plowshare experiments, was conducted at the Nevada Test Site. This 100-kiloton blast produced a crater approximately 1,200-feet-in-diameter, with a depth of 320 feet ...
