The microalgae Dunaliella tertiolecta phototrophically generates glycerol as an osmolyte in response to salt stress. This biogenic carbon sink is also a platform intermediate for the chemical sector. A synergistic genome and time resolved proteome analysis deciphered the metabolic pathways activated under salt stress. Immediately (30 min) Ca 2+ signaling pathways and ions channels are activated, while in the longer term (24 h)...

The iron (Fe)-oxide deposits of the Lahn-Dill-type are composed of haematite-quartz and rare siderite-haematite ores. These ores formed as marine chemical sediments on top of volcaniclastic rocks near the Middle to Late Devonian boundary (∼ 380 Ma). As such, their trace element fractionation patterns provide key information on venting style, ocean chemistry, particle-solution interaction, and depositional environment at the ti...
