🩸🧬 Delighted to share our new @nature.com paper! Genetic studies of >28,000 people reveal a BACH2-NRF2 pathway for activating fetal hemoglobin, suggesting new tx avenues for sickle cell disease & β-thalassemia. Led by the amazing Chun-Jie Guo & co! www.nature.com/articles/s41...

Human genetics implicates a BACH2–NRF2 axis in fetal haemoglobin activation - Nature
BACH2 restrains activation of the fetal-haemoglobin-encoding γ-globin genes, while loss of BACH2 enhances NRF2 chromatin occupancy and promotes the formation of activation foci at the γ-globin genes.

AI hugely accelerate some steps but not others. What happens to science when the cost of producing a plausibly looking paper is lower than the cost of its evaluation ? www.washingtonpost.com/education/20...
washingtonpost.com
Using AI, a professor wrote 200 papers this year. Researchers are alarmed.
An online platform removed 257 papers written or co-written by the University of Chicago’s Nicholas Polson after other academics raised questions.
