L1R, a myristylated late gene product of vaccinia virus, is essential for formation of infectious intracellular mature virions (IMV). In its absence, only viral particles arrested at an immature stage are detected and no infectious progeny virus are produced. Previous studies have shown that the L1R protein is exclusively associated...
The Office of Naval Research's Coupled Boundary Layers and Air–Sea Transfer (CBLAST) program is being conducted to investigate the processes that couple the marine boundary layers and govern the exchange of heat, mass, and momentum across the air–sea interface. CBLAST-LOW was designed to investigate these processes at the low-wind extreme...
Laboratory culture experiments were performed to establish the range of growth conditions where ¹³C labeling of di- and tri-unsaturated C₃₇ methyl ketones yields reliable growth rates for alkenone-producing algae. Results document that even at low growth rates and short time intervals, ¹³C labeling of the di-unsaturated C₃₇ alkenone provides reasonable...
In 2006, NASA led a field campaign to investigate the factors that control the fate of African easterly waves (AEWs) moving westward into the tropical Atlantic Ocean. Aircraft and surface-based equipment were based on Cape Verde's islands, helping to fill some of the data void between Africa and the Caribbean....
The Holocene portion of the Siple Dome (Antarctica) ice core was
dated by interpreting the electrical, visual and chemical properties of the
were interpreted manually and with a computer algorithm.The algorithm
was adjusted to be consistent with atmospheric methane stratigraphic
(Greenland Ice Sheet Project 2) ice core, ¹⁰Be stratigraphic ties...
Submersible exploration of the Samoan hotspot revealed a new, 300-m-tall, volcanic cone, named Nafanua, in the summit crater of Vailulu’u seamount. Nafanua grew from the 1,000-m-deep crater floor in <4 years and could reach the sea surface within decades. Vents fill Vailulu’u crater with a thick suspension of particulates and...
