Doctors have performed brain surgery on a fetus in one of the first operations of its kind
What’s happened: A seven-week-old baby girl is one of the first people to have undergone an experimental brain operation while still in the womb. She had developed a dangerous condition that led blood to pool in a tiny pocket in her brain, which could have resulted in brain damage, heart problems, and breathing difficulties after birth. The operation might have saved her life.
How they did it: Doctors used ultrasound imaging to help them guide a needle through the mother’s abdomen, the uterus wall, and the fetus’s skull and into the malformation in the brain. They then fed a tiny catheter through the needle to deliver a series of tiny platinum coils into the blood-filled pocket. Once each was released, it expanded, helping to block the point where the artery joined the vein. The baby girl was born healthy a couple of days later.
What’s next: The team behind the operation now plans to treat more fetuses with similar brain conditions in the same way. For conditions like these, fetal brain surgery could be the future. Read the full story.

The big story
How to spot AI-generated text
This sentence was written by an AI—or was it? OpenAI’s chatbot, ChatGPT, presents us with a problem: How will we know whether what we read online is written by a human or a machine?
Since it was released in November 2022, ChatGPT has been used by over a million people. It has the AI community enthralled, and it is clear the internet is increasingly being flooded with AI-generated text.
We’re in desperate need of ways to differentiate between human- and AI-written text in order to counter potential misuses of the technology. And while labs are racing to develop tools tasked with spotting AI-generated text, they’re not always reliable. Read the full story.
