A 1000-year-old mystery solved: Unlocking the molecular structure for the medieval blue from Chrozophora tinctoria, also known as folium

A 150 year-old mystery solved: Transfer of the rheophytic endemic liverwort Myriocolea irrorata to Colura

Myriocolea irrorata is an endemic rheophytic liverwort known from a few localities in the Eastern Andes of Ecuador. Morphologically it belongs to the Cololejeunea-Tuyamaella clade of Lejeuneaceae, however, due to its exclusively Radula-type branching, transversely inserted, hollow leaves, large size, and an extremely high number of clustered gynoecia it has often been regarded as an isolated el...

Mystery solved

Mutant mice lacking the integrin alpha8 subunit exhibit variable defects in kidney development with most mutants missing both kidneys. Several lines of evidence indicate that the known extracellular matrix ligands for integrin alpha8beta1 are either dispensable for or not involved in alpha8beta1 signaling during kidney development. This suggests the presence of an unknown ligand. A novel alpha8...

The magic angle: a solved mystery.

We resolve the long-standing mysterious discrepancy between the experimental magic angle in EELS--approximately 2theta(E)--and the quantum mechanical prediction of approximately 4theta(E). A relativistic approach surpassing the usually applied kinematic correction yields a magic angle close to the experimental value. The reason is that the relativistic correction of the inelastic scattering cro...

Furthermore, by using [2, p. 230, (1)] a computable representation for the G-function in (1) (and hence also for F,112(s)) may be given in terms of essentially a linear combination of four hypergeometric functions OF3[b2s2 /16] provided that no two of the parameters {1, 1 1+v-P1v-P) differ by an integer. This result for Fv-112(s) is given (correctly) in [3, p. 353, (9)] so that the proposed int...
