Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Cosmic-Ray Feedback on Bistable Interstellar Medium Turbulence

The Astrophysical Journal
While cosmic rays ( E ≳ 1 GeV) are well coupled to a galaxy’s interstellar medium (ISM) at scales of L > 100 pc, adjusting stratification and driving outflows, their impact on small scales is less clear.

A bifacial paradise—The site of Ochtmissen, Germany, and its lithic assemblage in the context of the last glacial (early MIS 4) in the north‐central European Lowland

Boreas, EarlyView.
The Palaeolithic site of Ochtmissen (Lower Saxony, Germany) was excavated in fluvial terrace deposits during the winter of 1993/1994. The current study presents, for the first time, a thorough analysis of the lithic assemblage, encompassing its primary technological and typological characteristics, as well as the type and age of the fluvial deposits ...

Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

ON THE COSMIC RAY LATITUDE KNEE AROUND CAPE TOWN ANOMALY

Antarctic Record, 1963
Investigations of results obtained from the five cosmic ray measurements aboard SOYA during 1956-62 show a double 'knee' in latitude dependence around Cape Town anomaly. The first 'knee' is always found near 40° geomagnetic latitude taking account of the

Eros as the Meeting of Ecstasies in Christ: The Eucharistic Link between Divine and Human Love in Dionysius the Areopagite

International Journal of Systematic Theology, EarlyView.
Abstract Dionysius's vision of eros as a meeting of reciprocal ecstasies – where lover and beloved each pass out of themselves and into the other – has often been read as unifying dimensions of love otherwise thought to stand in tension, such as giving and receiving.
