Your daily dose of what's up in emerging technology
By Rhiannon Williams • 1.19.24
Hello, and happy Friday! Today: doctors are exploring how to use animal organs for human transplants—by keeping them outside patients' bodies. Plus: how a new AI project hopes to help reverse the impacts of racial segregation in South Africa, and the first gene-editing treatment is giving people living with sickle-cell disease new hope—but it comes with a hefty price tag. Whatever you're up to, have a great weekend!
A brain-dead man was attached to a gene-edited pig liver for three days
Surgeon Abraham Shaked thinks he has probably carried out more than 2,500 liver transplants. But in December 2023, the team he oversees at the University of Pennsylvania did something he'd never tried before.
Working on the body of a brain-dead man, they attached his veins to a refrigerator-size machine with a pig liver mounted in the middle of it. For three days, the man's blood passed into the machine, through the pig liver, and back into his body.
This "extracorporeal," or outside-the-body, liver is designed to help people survive acute liver failure. The idea is to use the external organ to support people with liver failure until a human liver transplant becomes available for them—or until their livers bounce back. Read the full story.

How satellite images and AI could help fight spatial apartheid in South Africa
Raesetje Sefala grew up sharing a bedroom with her six siblings in a cramped township in the Limpopo province of South Africa. The township's inhabitants, predominantly Black people, had inadequate access to schools, health care, parks, and hospitals.
Just a few miles away in Limpopo, white families lived in big, attractive houses, with easy access to all these things. The older Sefala became, the more she peppered her father with questions about the visible racial segregation of their neighborhood: "Why is it like this?"
Now, at 28, she is helping do something about it. Alongside computer scientists Nyalleng Moorosi and Timnit Gebru at the nonprofit Distributed AI Research Institute (DAIR), which Gebru set up in 2021, she is deploying computer vision tools and satellite images to analyze the impacts of racial segregation in housing, with the ultimate hope that their work will help to reverse it.

The first gene-editing treatment: 10 Breakthrough Technologies 2024
It was only 11 years ago that scientists first developed the potent DNA-snipping technology called CRISPR. Now they've brought CRISPR out of the lab and into real medicine with a treatment that cures the symptoms of sickle-cell disease.
Sickle-cell is caused by inheriting two bad copies of one of the genes that make hemoglobin. Symptoms include bouts of intense pain, and life expectancy with the disease is just 53 years. It affects 1 in 4,000 people in the US, nearly all of them African-American.
The news is undoubtedly good. But the expected price tag of the gene-editing treatment is $2 to $3 million. And Vertex has no immediate plans to offer it in Africa—where sickle-cell disease is most common, and where it still kills children. Read the full story.

The big story
AI hype is built on high test scores. Those tests are flawed.
August 2023
In the past few years, multiple researchers claim to have shown that large language models can pass cognitive tests designed for humans, from working through problems step by step, to guessing what other people are thinking.
These kinds of results are feeding a hype machine predicting that these machines will soon come for white-collar jobs. But there's a problem: There's little agreement on what those results really mean. Read the full story.
