Humboldt’s annotations about the social situation of the Canary Islands and his influence on the German speaking travelers in the 19th century

La corta estancia de Humboldt en las Islas Canarias supuso para muchos científicos e intelectuales de lengua alemana un «redescubrimiento» del Archipiélago y, así, por influencia directa o indirecta de Humboldt, viajaron a Canarias geólogos, botánicos, zoólogos, pintores e incluso juristas. Los testimonios que nos han legado tienen naturaleza eminentemente científica, aunque —siguiendo el ejemplo del prusiano— la mayoría de ellos se hace eco en sus obras de la deplorable situación social y económica en la que se encontraba la población insular. En nuestro trabajo analizamos la imagen del régimen señorial que ofrecen los viajeros del siglo XIX en Canarias y mostramos cómo centran su atención en problemas de los que ya Humboldt se había ocupado.Humboldt’s short stay on the Canary Islands evoked to many German scientists a rediscovery of the archipelago. Directly and indirectly stimulated, geologists, botanists, zoologists, painters and even jurists visited the islands, completing Humboldt’s work in many areas. Their testimonies are merely scientific, although —following Humboldt’s example— the majority mentions the unfavorable economic and social situation of the local population. With our article we analyze the image which the almost feudal conditions had generated to the 19th century voyagers and would like to show that they paid attention in many cases to problems that Humboldt —the Prussian supporter of the French revolution— had mentioned ye

The Stubenberg meteorite—An LL6 chondrite fragmental breccia recovered soon after precise prediction of the strewn field

On March 6, 2016 at 21:36:51 UT, extended areas of Upper Austria, Bavaria (Germany) and the southwestern part of the Czech Republic were illuminated by a very bright bolide. This bolide was recorded by instruments in the Czech part of the European Fireball Network and it enabled complex and precise description of this event including prediction of the impact area. So far six meteorites totaling 1473 g have been found in the predicted area. The first pieces were recovered on March 12, 2016 on a field close to the village of Stubenberg (Bavaria). Stubenberg is a weakly shocked (S3) fragmental breccia consisting of abundant highly recrystallized rock fragments embedded in a clastic matrix. The texture, the large grain size of plagioclase, and the homogeneous compositions of olivine (Fa31.4) and pyroxene (Fs25.4) clearly indicate that Stubenberg is an LL6 chondrite breccia. This is consistent with the data on O, Ti, and Cr isotopes. Stubenberg does not contain solar wind-implanted noble gases. Data on the bulk chemistry, IR spectroscopy, cosmogenic nuclides, and organic components also indicate similarities to other metamorphosed LL chondrites. Noble gas studies reveal that the meteorite has a cosmic ray exposure (CRE) age of 36 ± 3 Ma and that most of the cosmogenic gases were produced in a meteoroid with a radius of at least 35 cm. This is larger than the size of the meteoroid which entered the Earth's atmosphere, which is constrained to <20 cm from short-lived radionuclide data. In combination, this might suggest a complex exposure history for Stubenberg.PostprintPeer reviewe

Starship Troopers

In Robert A. Heinlein\u27s controversial bestseller, a recruit of the future goes through the toughest boot camp in the Universe—and into battle against mankind\u27s most alarming enemy. JOIN THE ARMY AND SEE THE UNIVERSE The historians can\u27t seem to settle whether to call this one “The Third Space War” (or the fourth), or whether “The First Interstellar War” fits it better. The soldiers just call it “The Bug War.” Everything up to then and still later were “incidents,” “patrols,” or “police actions.” In the Mobile Infantry, everybody fights. But you\u27re just as dead if you buy the farm in an “incident” as you are if you buy it in a declared war...“A classic…If you want a great military adventure, this one is for you.”—All SciF

Simultaneous Detection of mRNA and Protein in S. cerevisiae by Single-Molecule FISH and Immunofluorescence

Single-molecule fluorescent in situ hybridization (smFISH) enables the detection and quantification of endogenous mRNAs within intact fixed cells. This method utilizes tens of singly labeled fluorescent DNA probes hybridized against the mRNA of interest, which can be detected by using standard wide-field fluorescence microscopy. This approach provides the means to generate absolute quantifications of gene expression within single cells, which can be used to link molecular fluctuations to phenotypes. To be able to correlate the expression of an mRNA and a protein of interest in individual cells, we combined smFISH with immunofluorescence (IF) in yeast cells. Here, we present our smFISH-IF protocol to visualize and quantify two cell cycle-controlled mRNAs (CLN2 and ASH1) and the cell cycle marker alpha-tubulin in S. cerevisiae. This protocol, which is performed over 2 days, can be used to visualize up to three colors at the time (i.e., two mRNAs, one protein). Even if the described protocol is designed for S. cerevisiae, we think that the considerations discussed here can be useful to develop and troubleshoot smFISH-IF protocols for other model organisms
