Molecular models and data
// Journal Covers
The research team proposes a complementary interpretation of the mechanism responsible for the strong enhancement observed in surface enhanced raman scattering (SERS).
Microbe images
// Journal Covers
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.
Valenc electron images
// Journal Covers
We report an attosecond pump–probe measurement of the density matrix of valence electrons in atomic krypton ions.
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.

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.

Astronauts at the Nevada Test Site
// A Look Back
In February 1965, Apollo astronauts paid a visit to the pockmarked desert of the Nevada Test Site as part of their lunar training.

// A Look Back
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 ...
