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.

And once promising stuff seems to happen clean streak some colonies, test and sequence (you can also sequence population) but clean streaked colonies is neater usually

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.

I'm going to be advertising for a few positions in my group in the next couple of months for a big project on synthetic microbial communities.

I would love to hear from you if you are interested and I'd also appreciate if everyone could share this far and wide!

#Growth-coupled #selection just got an update ! In the last years, E. coli selection strains for #central , #amino #acid and #energy metabolism intermediates were created by the community. So, we compiled them and revisit the core concepts of growth coupling.

Proteins of amino acid metabolism form large structures and determine diffusion in the cytoplasm!

I get annoyed at the narrative that all the awareness and work on climate change hasn't done anything. Yes, global CO₂ emissions indeed continue to climb, but we don't know the counterfactual. When I was in grad school, we were on track for 5°C of warming. Now it's below 3°C. That's progress.

A line chart titled “Annual CO₂ emissions” shows the global carbon dioxide emissions from fossil fuels and industry from 1950 to 2023. The y-axis represents emissions in billions of tonnes (t), ranging from 0 to 40 billion t. The x-axis covers the years from 1950 to 2023.

The chart presents a steady increase in emissions from approximately 5 billion tonnes in 1950 to over 36 billion tonnes in 2023. Key features include:

A consistent upward trend from 1950 through the early 1970s.

A brief plateau and dip around 1980–1983.

A strong growth trend resuming in the late 1980s.

A sharp increase during the 2000s.

A slight drop around 2008–2009, likely due to the global financial crisis.

A major dip in 2020, attributed to the COVID-19 pandemic.

A rapid rebound in emissions after 2020, continuing the upward trend to a new high in 2023.

A blue line labeled “World” traces these changes over time.

Below the chart, the data source is listed as the Global Carbon Budget (2024), and the graphic is credited to OurWorldInData.org with a Creative Commons license (CC BY). A footnote explains that the data includes emissions from coal, oil, gas, flaring, cement, and steel, but excludes land-use changes such as deforestation.
