PSA: around 5-8% of the population has a color vision impairment for red/green. Many talks at #2025ICDB still use red-green LUTs on slides that are not accessible to everyone. Changing to more accessible colors is doable and easy. We can do better. #devbio #ICDB2025 #WeTheColorBlind

„Anyone who has studied science under the Nazis, as I did for my book Serving the Reich, cannot fail to be dismayed and alarmed at the parallels in the response so far of scientific institutions and academies to the purges and abuses of power following Trump’s executive orders“ 🧪

Scientific institutions have a long history of anticipatory obedience
Societies should learn from this and speak up to support inclusion
