    PNAS is here! Pictured is a developing Arabidopsis thaliana lateral root, with cell outlines shown in blue. Yujuan Du and Ben Scheres found that the PLETHORA transcription factors PLT3, PLT5, and PLT7 regulate the initiation of cell divisions at the start of Arabidopsis lateral root development. According to the authors, PLETHORA transcription factors are key molecular triggers for the establishment of new meristems and tissue differentiation associated with a new growth axis.

    During the Dust Bowl, archaeologist Waldo Wedel began studying the Great Plains to determine how cultures had historically survived despite drought, crop failure, and soil loss. With his wife and research partner, Mildred, Waldo took a Direct Historical Approach to his research, by looking at the culture and materials of modern people in the area and working backward. He was an early advocate of environmental and ecological approaches to archaeology. Find out how his emphasis on settlement patterns and cultural geography helped develop a comprehensive chronology of the Great Plains. bit.ly/NASWedel #MemoirMonday #archaeologist #science #GreatPlains #DustBowl #SettlementPattern #CulturalGeography #NativeAmericans #ecology #environment #archaeology #AmericanIndianHeritageMonth #Pawnee #RiverBasinSurveys

    The NAS Award in Chemical Sciences is presented annually to honor innovative research that contributes to a better understanding of the natural sciences and to the benefit of humanity. In 2016 #NASmember Carolyn Bertozzi of @stanford received the award founding bio-orthogonal chemistry, and applying this novel chemistry to install artificial sugars on the surface of living cells, enabling the study of their roles in cancer and the immune system. Winners do not have to be members of the NAS. #NationalChemistryWeek #science #chemistry #ArtificalSugar #cancer #ImmuneSystem #BioorthogonalChemistry #CarolynBertozzi

    Every other year, the NAS honors contributions to chemistry that satisfy a need in society with the NAS Award for Chemistry in Service to Society. Recipients are not always members of the NAS. In 2017 #NASmember Leroy Hood received the award for revolutionary work in biology and medicine. One of his chemical developments is the automated DNA sequencer. This tool spearheaded the Human Genome Project. #science #chemistry #NationalChemistryWeek #biology #medicine #NDAsequencer #HumanGenomeProject #LeeHood #biotech #innovator
