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

On the influence of the environment on galactic chemical abundances
, 2020 © 2016 The Authors. We examine the influence of the environment on the chemical abundances of late-type galaxies with masses of 10 9.1 -10 11 M⊙ using data from the Sloan Digital Sky Survey.

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.

Aeos Is Mixing It Up: The (In)homogeneity of Metal Mixing Following Population III Star Formation
The Astrophysical JournalStellar surface abundances are records of the state of the gas from which stars formed and thus trace how individual elements have mixed into the surrounding medium following their ejection from stars.

Chemical Abundances in SFG and DLA
, 2005 We investigate the chemical abundances of local star-forming galaxies which cause Damped Lyman Alpha lines. A metallicity versus redshift diagram is constructed, on which the chemical abundances of low-redshift star-forming galaxy populations are compared with those of high-redshift Damped Lyman Alpha systems.

Chemical abundances and chemical evolution of the Magellanic Clouds: Prospects for the future [PDF]
Symposium - International Astronomical Union, 1991 The prospects for future advances in understanding the chemical evolution of the Magellanic Clouds is reviewed on the basis of results presented at IAU Symposium #148. These are divided into three areas, the metallicity - age relationships, the current abundance set, and the theory of the chemical evolution of the Clouds.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma
FEBS Letters, EarlyView.Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Element Nucleosynthetic Origins from Abundance Spatial Distributions beyond the Milky Way
The Astrophysical Journal LettersAn element’s astrophysical origin should be reflected in the spatial distribution of its abundance, yielding measurably different spatial distributions for elements with different nucleosynthetic sites.

Metastatic niche shaped by host factors influences disseminated cancer cell fate
FEBS Letters, EarlyView.Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...
