The Download: stem cell experiments, and coining “embryo tech”

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

A biotech company says it put dopamine-making cells into people’s brains

The news: In an important test for stem-cell medicine, biotech company BlueRock Therapeutics says implants of lab-made neurons introduced into the brains of 12 people with Parkinson’s disease appear to be safe and may have reduced symptoms for some of them.

How it works: The new cells produce the neurotransmitter dopamine, a shortage of which is what produces the devastating symptoms of Parkinson’s, including problems moving. The replacement neurons were manufactured using powerful stem cells originally sourced from a human embryo created using an in vitro fertilization procedure.

Why it matters: The small-scale trial is one of the largest and most costly tests yet of embryonic-stem-cell technology, the controversial and much-hyped approach of using stem cells taken from IVF embryos to produce replacement tissue and body parts. Read the full story.

Here’s why I am coining the term “embryo tech”

Antonio, our senior biomedicine editor, has been following experiments using embryonic stem cells for quite some time. He has coined the term “embryo tech” for the  powerful technology researchers can extract by studying them, which includes new ways of reproducing through IVF—and could even hold clues to real rejuvenation science.

The big story

El Paso was “drought-proof.” Climate change is pushing its limits.


December 2021

El Paso has long been a model for water conservation. It’s done all the right things—it’s launched programs to persuade residents to use less water and deployed technological systems, including desalination and wastewater recycling, to add to its water resources. A former president of the water utility once famously declared El Paso “drought-proof.” 

Now, though, even El Paso’s careful plans are being challenged by intense droughts. As the pressure ratchets up, El Paso, and places like it, force us to ask just how far adaptation can go. Read the full story.
