Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

The Modern Reproduction of a Mongol Era Bow Based on Historical Facts and Ancient Technology Research

EXARC Journal, 2017
This bow was a concept, commissioned from Ulrich Velthuysen, a Swedish archer. This horn bow could be classified as a post-conquest design from early 14th century AD Mongolia.

An Experimental Approach to Assessing the Tempering and Firing of Local Pottery Production in Nubia during the New Kingdom Period

EXARC Journal, 2022
Recently, the development of an independent strand of study, known as the ‘archaeology of dung,’ has resulted in numerous cross-geographical publications confirming the use of animal dung in archaeological deposits as the main fuel source and several ...

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

A Preliminary Attempt to Reconstruct some Tools and Techniques of Ornamentation of the Comb-Pit Ware from the Site of Hepojarvi (Karelian Isthmus, Leningrad Oblast, Russia)

EXARC Journal, 2019
The site of Hepojarvi is located on the northern coast of Hepojarvi lake, near Saint Petersburg, Russia. The site is a multi-layer settlement with different types of Neolithic pottery (from Sperrings to late Comb-Pit Ware); the settlement functioned in ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

FEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.
