Time to leverage SynBio for tacking environmental pollution. But releasing bioengineered microorganisms still raises alarms. A new narrative is badly needed: bacteria for bioremediation are not alien intrusions but laboratory-trained extensions of life’s creativity link.springer.com/10.1038/s443...

Nice opinion Victor! I like the way of thinking to make regulations for engineered organisms more based on biochemical rules than on genetic rules, or maybe in general we should move to rules based on applications, are these beneficial to the planet and humanity, or just for making profit

Doing a PhD is - at heart - one long discussion with your mentor. The discussion changes over time - with unexpected turns and ups & downs - but through it all is a pair of people discussing a topic endlessly to make sense of it.
PhD students: choose someone you like to talk to!

Our new paper is out: we present a quantitative framework to assess how (bio)tech interventions in plant agriculture could meaningfully contribute to climate mitigation.

In my left hand I am holding the package of the 'hey mela' pregnancy test. The first vegan pregnancy test in the world. Now available in Germany.

'hey mela' is the first vegan pregnancy test in the world. Now available in Germany.

What could be vegan about it?

These tests are based on antibodies that are usually farmed from small rodents kept in cages, infected with hybridoma cells.

This test is based on AB expressed from algae!! 🧪

Fijn dat het deze verkiezingen een keer over belastingen gaat.
Nu nog zorgen dat de feiten het winnen van de framing.

De middenklasse in NL betaalt de belastingkortingen van de allerrijksten. Hoe rijker je bent, hoe lager je belastingdruk.

Dit komt door politieke keuzes. Ga stemmen 29 oktober.

Sounds like a good plan to keep it simple and start like that, worked often well for us. Try to see maybe based on limited intermediate OD checks (glass tubes that fit in spectrophotometer can be convenient) if strain already speeds up, so you can see soon enough if better strains take over the pop.
