When setting goals, we often focus on achieving milestones like a PhD, job, tenure, or promotion. Those are great goals but they’re not enough.

We also need to think about:
-Why we’re pursuing that goal
-What specifically we need to do to succeed
-The values we will follow as we do the work

Oxidative stress sensing by the translation elongation machinery promotes production of detoxifying selenoproteins Selenocysteine, incorporated into polypeptides at recoded termination codons, plays an essential role in redox biology. Using GPX1 and GPX4, selenoenzymes that mitigate oxidative stress, as reporters,...

Colliding ribosomes are potent signals of cellular stress. But do cells use ‘programmed’ ribosome collisions to regulate gene expression? I’m excited to present a new story from my lab led by Frederick Rehfeld(@fred-rehfeld.bsky.social) which revealed that the answer is YES! Read on to find out how👇
