Discovery of meteorites on a blue-ice field near the Frontier Mountains, North Victoria Land, Antarctica

A high concentration of meteorites were discovered on a blue ice field northeast of the Frontier Mountains. As a result of a systematic search, a total of 42 meteorites were recovered. The current glacial situation has evolved through various stages, which are discussed in relationship to the concentration of meteorites. Ice flow patterns are summarized. The chemical composition and terrestrial ages of the meteorites are discussed

The Arabidopsis ROP-activated receptor-like cytoplasmic kinase RLCK VI_A3 is involved in control of basal resistance to powdery mildew and trichome branching.

KEY MESSAGE: The Arabidopsis receptor-like cytoplasmic kinase AtRLCK VI_A3 is activated by AtROPs and is involved in trichome branching and pathogen interaction. Receptor-like cytoplasmic kinases (RLCKs) belong to the large superfamily of receptor-like kinases, which are involved in a variety of cellular processes like plant growth, development and immune responses. Recent studies suggest that RLCKs of the VI_A subfamily are possible downstream effectors of the small monomeric G proteins of the plant-specific Rho family, called 'Rho of plants' (RAC/ROPs). Here, we describe Arabidopsis thaliana AtRLCK VI_A3 as a molecular interactor of AtROPs. In Arabidopsis epidermal cells, transient co-expression of plasma membrane located constitutively activated (CA) AtROP4 or CA AtROP6 resulting in the recruitment of green fluorescent protein-tagged AtRLCK VI_A3 to the cell periphery. Intrinsic kinase activity of AtRLCK VI_A3 was enhanced in the presence of CA AtROP6 in vitro and further suggested a functional interaction between the proteins. In the interaction of the biotrophic powdery mildew fungus Erysiphe cruciferarum (E. cruciferarum) and its host plant Arabidopsis, Atrlck VI_A3 mutant lines supported enhanced fungal reproduction. Furthermore Atrlck VI_A3 mutant lines showed slightly reduced size and an increase in trichome branch number compared to wild-type plants. In summary, our data suggest a role of the AtROP-regulated AtRLCK VI_A3 in basal resistance to E. cruciferarum as well as in plant growth and cellular differentiation during trichome morphogenesis. Results are discussed in the context of literature suggesting a function of RAC/ROPs in both resistance and susceptibility to pathogen infection

Espíritus en los bosques: una socioecología de las “naturalezas salvajes” brasileñas

Aquest article proposa innovacions teòriques, metodològiques i empíriques que poden expressar millor la riquesa de les cosmovisions no seculars i llur relació amb aspectes ambientals globals. S’empra un enfocament relacional de les “natures salvatges” brasileres per dialogar amb cosmovisions animistes i espiritualment bifurcades i tal vegada fins i tot amb éssers no humans de manera que es pugui promoure una conservació ambiental socialment inclusiva. Això resulta de màxima importància en un moment en què el naturalisme naïf de la conservació biocèntrica basat en l’anomenada “(re)naturalització” no està mitigant pas les emissions de carboni ni el canvi climàtic de forma significativa. Per tal d’assolir una mena de conservació més espiritual, dos dels catorze modes d’existència de Latour en una cosmovisió científica reformada —la religió [REL] i la metamorfosi [MET]— estan relacionats amb la conservació ambiental. Es presenten quatre tipus ideals de cosmovisió que es mostren hibridats en tres biomes diferents del Brasil. Es demostra que les cosmovisions híbrides, animistes i espiritualment bifurcades predominen a les regions boscoses preservades del país. Des d’una perspectiva constructivista, aquestes cosmovisions es relacionen amb la conservació socioecològica relacional, superant la seva omissió per part de les mentalitats dominants als parcs nacionals biocèntrics de biaix urbà.This article proposes theoretical, methodological and empirical innovations which can better express the richness of non-secular worldviews and their relationship to global environmental issues. A relational approach to the Brazilian “wilds” is used to dialogue with animist and spiritually bifurcated worldviews and perhaps even with non-human beings in a way that promotes socially-inclusive environmental conservation. This is of the utmost importance at a time when the naïve naturalism of biocentric conservation of the so-called (re)wilds is not mitigating global carbon emissions and climate change in any significant way. In the search for a more spiritual kind of conservation, two of Latour’s fourteen modes of existence in a reformed scientific worldview — religion [REL] and metamorphosis [MET] — are related to environmental conservation. Four ideal types of worldview are presented and shown to be hybridized in three different biomes of Brazil. Hybridized animist-spiritually bifurcated worldviews are shown to predominate in preserved wooded regions of the country and are constructively engaged by relational socio-ecological conservation rather than ignored by urban-biased biocentric national park mentalities.Este artículo propone innovaciones teóricas, metodológicas y empíricas que pueden expresar mejor la riqueza de las cosmovisiones no seculares y su relación con aspectos ambientales globales.

The early history of Parke-Davis and Company

The history of the pharmaceutical company called Parke-Davis and Company is traced. The company originated as a partnership between Dr. Samuel Duffield and Hervey C. Parke in 1866. Duffield withdrew from the business in 1871 and George S. Davis entered into the picture. By 1890, Parke-David has become a successful and prosperous company. However, in 1961, the company was in a downward spiral. It was later purchased by Warner-Lambert in 1974
