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,...

👀 "An entire lane of solo drivers on Denny Way between Seattle Center and I-4 can fit into one articulated Route 8 bus, and a dedicated transit lane would allow that bus to be over four times faster than driving along this section"

Cars just don't scale well, especially in dense cities.

yearly reminder to people insisting that we view Christopher Columbus as "a man of his time" that *the people responsible for the Spanish Inquisition* thought Columbus was out of pocket

Thomas Lecaque @tlecaque.bsky.social · 1d

Christopher Columbus was dragged back to Spain in chains by a crusading knight, convicted of tyranny and immeasurable cruelty, pardoned by Isabella but banned from returning to Hispaniola.

Fuck Columbus.

A lot changes over time. Including knowledge/memory of the road rules, driver skills and ability, and the size and deadliness of vehicles.

Standing up to fascism is always the right choice.

Rejecting censorship is always the right choice.

Fighting for marginalized and vulnerable communities is always the right choice.
