We present the WD2014 chronology for the upper
part (0–2850 m; 31.2 ka BP) of the West Antarctic Ice Sheet
(WAIS) Divide (WD) ice core. The chronology is based on
counting of annual layers observed in the chemical, dust
and electrical conductivity records. These layers are caused
by seasonal changes...

The last glacial period exhibited abrupt Dansgaard–Oeschger climatic oscillations, evidence of which is preserved in a variety of Northern Hemisphere palaeoclimate archives¹. Ice cores show that Antarctica cooled during the warm phases of the Greenland Dansgaard–Oeschger cycle and vice versa[superscript 2,3], suggesting an interhemispheric redistribution of heat through a mechanism...
Genetic code expansion is a technology that allows for site-specific incorporation of noncanonical amino acids into recombinant proteins at amber stop codons using engineered translational machinery. The technology allows for expanded study into proteins, derived from the integration of novel chemical functions found in noncanonical amino acids, such as fluorescence,...
Boreal and temperate biomes host nearly half of the earth’s forested ecosystems. The temperate rainforests of the Pacific coast of North America constitute nearly half of all temperate rainforests on earth. Along the northern extent of this region, the perhumid and sub-polar rainforests of southeast and southcentral Alaska are among...
In nanoscale materials, the Coulombic interaction between electrons are stronger than in bulk materials. These stronger interactions, caused by confinement and reduced dielectric screening, have interesting consequences for light-matter interactions. In carbon nanotubes (CNTs), strong interactions can enhance the impact ionization process, and thus assist photocurrent generation in CNTs. Conversely,...
Metamorphosed volcanogenic rocks of the Permian and Triassic Seven Devils Group are exposed in the northern part of the Heavens Gate 7.5 minute quadrangle, western Idaho. These rocks originated in a volcanic arc at a destructive plate margin. In the north, rocks that probably belong to the Lower Permian Hunsaker...
