Out of scores of climate papers I read this year, this might be the coolest... and most troubling? Turns out the genes of Southern Ocean octopus populations show that the West Antarctic Ice Sheet collapsed 120,000 years ago at temperatures like today's 🧪 😬

This Antarctic Octopus Has a Warning About Rising Sea Levels
A huge ice sheet appears to have melted about 120,000 years ago, when temperatures were similar to those on Earth today, according to a DNA study that mapped octopus movements.

Scientists 🧪 were like "Hey, you know how we can get DNA into our experimental organisms using electricity? You think...we could use electric eels for that?". h

They did the experiment, and the answer was hell yeah we can.

WILD new paper from Shintaro Sakaki et al

A Figure 1: EOD exposure from electric eel to zebrafish larvae. (A) This illustration depicts the experimental tank used to expose the recipient organism to the electric eel’s electric organ discharge (EOD). Within the tank, three carbon rod electrodes are placed: two inputs (colored black and red) and a ground electrode (colored green). (B) An EOD is induced by the electric eel during its predatory behavior when it feeds on a goldfish. The cuvette containing zebrafish larvae and a DNA solution is positioned in close proximity to the high-voltage pulses generated by the electric eel. The magenta curve illustrates the electric field produced by the electric eel. (C) This illustration indicates the construction of the GFP expression plasmid driven by the Oryzias latipes actb promoter. (D) The photograph displays 7-day post-fertilization (dpf) Danio rerio (zebrafish) larvae that were subjected to microinjection with the indicator plasmid at the one-to-eight cell stages. The plasmid has re
