The Download: Synthetic cow embryos, and AI jobs of the future
About a decade ago, biologists started to observe that stem cells, left alone in a walled plastic container, will spontaneously self-assemble and try to make an embryo. These structures, sometimes called “embryo models” or embryoids, have gradually become increasingly realistic.
The University of Florida is trying to create a large animal starting only from stem cells—no egg, no sperm, and no conception. They’ve transferred “synthetic embryos,” artificial structures created in a lab, to the uteruses of eight cows in the hope that some might take.
At the Florida center, researchers are now attempting to go all the way. They want to make a live animal. If they do, it wouldn’t just be a totally new way to breed cattle. It could shake our notion of what life even is. Read the full story.

Job titles of the future: AI prompt engineer
The role of AI prompt engineer attracted attention for its high-six-figure salaries when it emerged in early 2023. Companies define it in different ways, but its principal aim is to help a company integrate AI into its operations.
Danai Myrtzani of Sleed, a digital marketing agency in Greece, describes herself as more prompter than engineer. She joined the company in March 2023 as one of two experts on its new experimental-AI team, and has helped develop a tool that generates personalized LinkedIn posts for clients. Here’s what she has to say about her work.
