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👇
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,...

Leadership skills are similar to research skills - we aren’t born knowing the best approaches but we can learn.
And just like learning how to be a researcher, growing as a leader involves making mistakes, listening to feedback, and improving over time.

The path to excellence is rarely a straight line; it comes with ups and downs, twists and turns. Let’s not fixate on the end goal so much that we may overlook valuable lessons along the way.

We all need mentors, and the further we go in our careers, the more mentors we need.
Whether it’s dealing with increasingly complex career situations, considering a career transition, or coping with a career ending, mentors can be an essential source of wisdom and support.

According to the textbooks, we lost the ability to make vitamin C because our diet meant that we didn't need it. But studies in animals suggest it had an unexpected benefit.
The real reason why we lost the ability to make vitamin C
The textbooks say our ancestors lost the ability to make vitamin C because we didn't need it, but the loss may have protected us from some parasites
