Feitje van de dag

De geur van de zee wordt niet door zout veroorzaakt, maar door een mix van chemicaliën, waarvan dimethylsulfide de grootste veroorzaker van de geur is. Dit gas wordt geproduceerd door bacteriën die dode algen en zeewier opeten. Ditzelfde gas vind je in bier en scheten.

Everybody needs to calm their tits about the purported detection of dimethylsulfide at K2-18b. 1) It could very well be a statistical bias or artifact, and 2) it's not a definitive biosignature in any case. There's dimethylsulfide on Mars and in comets too, but no one thinks that's proof of life.

De plankton­rijke wereldzeeën doen méér dan het opnemen van CO₂: plankton produceert het gas dimethylsulfide (DMS) dat, na chemische reacties in de atmosfeer, leidt tot wolken met meer, maar kleinere druppeltjes. Deze wolken zijn daardoor witter en weerkaatsen meer zonlicht terug de ruimte in.

De 'hint of life' is heel mager (zie 🧵 hieronder), maar de timing met het aankomende aspergeseizoen is wel uitermate perfect.
De mogelijks gedetecteerde molecule is immers dimethylsulfide, één van de afbraakproducten van het asperagusinezuur, wat de typische aspergegeur in urine oplevert ;)

It's #NationalBeachDay!

Do you love the smell of the sea? 🌊 For the large part, what you're enjoying is the smell of algal decay with notes of seaweed sex. You're welcome!

The complex with undergoing an oxygen atom transfer reaction, converting DMSO to dimethylsulfide. I took the NMR sample out of the glove box and smelled it, sampling the delightful (to me at the time) smell of rotten eggs from the dimethyl sulfide.

Potential for microbial methanethiol-dependent dimethylsulfide production in different marine sediments
Potential for microbial methanethiol-dependent dimethylsulfide production in different marine sediments
Guo et al. demonstrate that H2S/MeSH-dependent DMS production through the Mdd pathway is prevalent in different types of marine sediments, including pelagic deep-sea sediments, and may substantially contribute to oceanic DMS production.

En verder worden doorgaans andere zwavelverbindingen toegevoegd aan methaan om eventuele lekken detecteerbaar te maken. Methaanthiol volgens mij, maar misschien was het dimethylsulfide.

It's just dimethylsulfide? Surely that's not fueling speculation of life 😅 like surely we know that intense radiation and random chance can form molecules at that level of complexity 👀

Duvel is inderdaad geen echte tripel, maar ligt er wel aardig tegenaan vind ik.
Vooral de Tripel van La trappe staat net als Duvel bekend door de typerende smaak die ontstaat door DMS (dimethylsulfide)

De planktonrijke wereldzeeën doen méér dan het opnemen van CO₂: plankton produceert het gas dimethylsulfide (DMS) dat, na chemische reacties in de atmosfeer, leidt tot wolken met meer, maar kleinere druppeltjes. Deze wolken zijn daardoor witter en weerkaatsen meer zonlicht terug de ruimte in. Zo koelt het zeeleven het klimaat op aarde.

The S-methyltransferase enzyme MddH produces DMS from hydrogen sulfide and methanethiol and its gene abundance rivals that of other known genes whose products generate DMS in marine environments.

I'm excited to extend next year's #ZOO3700 plankton lecture to include a digression into #dinoflagellates and #dimethylsulfide!

how you smell the ocean
how parasitoids find their prey
how clouds are formed
how we find life on another planet

Dinoflagellates - you rock!
