With Eugene Koonin, we propose a concept of “the selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268

Tell Congress to reject Arctic drilling The Trump EPA’s plan to roll back crucial climate and environmental regulations will dismantle decades of progress in reducing harmful climate pollution. It’s a giveaway to Big Oil, and it comes at ev...

Congress is considering opening up the Arctic National Wildlife Refuge in Alaska to oil drilling in their latest government funding bill.

We can’t let this happen – demand that Congress rejects Arctic drilling in this bill.

Cells are swapping their mitochondria. What does this mean for our health? Researchers are studying why the energy factories are moving between cells and whether the process can be harnessed to treat cancer and other diseases.

#mitochondria ... and you still call us powerhouses!

Congratulations!

Also, they are hermaphroditic. If two tripodfish happen to meet, they mate. But if there is no partner, no problem: one fish can produce both sperms and eggs and reproduce by itself.

Not sure how this sponge feels being out of the water!
#Porifera

Cool #mitochondria (the rest is not bad either!)
