When the temperature drops, octopuses recode their RNA in thousands of places to alter the proteins made in their nerve cells
at Tel Aviv University in Israel, who also worked on the study. He says the reason for this isn’t completely known.
Kinesin-1 is responsible for transporting chemical cargo across long microtubules inside neurons, which can extend to a metre in length. As they travel, kinesins look like they are walking with tiny feet. The RNA editing changed part of the kinesin’s “foot” where it connects to the microtubules, making it travel more slowly at lower temperatures.

EU maintains recommendation on Covid-19 vaccines for pregnant womenHealth officials continue to recommend the Covid-19 vaccine during pregnancy, contrary to claims circulating on social media which falsely say it impacts fertility, misinterpreting an advisory from the European Medicines Agency (EMA) about possible changes to a person's menstrual cycle following messenger RNA shots. To date, the jabs have not been linked to adverse outcomes specific to pregnancy, whereas a coronavirus infection does increase the risk of complications, according to experts.
