This week on Quantum Curiosities, Anna and Professor Halloway discuss the brain as a prediction machine. Rather than passively taking in the world, your brain is constantly guessing what's about to happen, filling in gaps, anticipating outcomes, and updating its predictions as things develop. They dig into how this predictive machinery shapes everything from perception to decision-making, and what happens when the predictions go wrong.

Anna Dean and Professor Clarke Halloway tackle the oldest question in human history: why are we here? Instead of relying on pre-written cosmic scripts, they examine how the sheer improbability of the physical universe sets the stage for human existence. The conversation moves past the anxiety of an indifferent cosmos and challenges you to look at your life not as a passive accident, but as an active experiment.

This episode of Quantum Curiosities and Tech Revelations breaks down the philosophical shift from searching for external validation to taking responsibility for your own purpose. You will hear why giving up on a grand, universal mandate is actually a liberating step. Meaning is not something you find waiting for you, but a structure you build yourself through your daily choices, relationships, and actions.

In this episode Anna and Professor Halloway discuss Midjourney's new Ultrasonic full body scanner technology.

Midjourney's Ultrasonic CT scanner is the flagship product of Midjourney Medical, a healthcare division the AI-image-generation company launched in June 2026. It's a full-body imaging device that uses ultrasound instead of radiation or magnets — essentially a "whole-body ultrasound" that captures a scan in as little as 60 seconds. The system relies on ultrasound-on-chip technology (developed in co-operation with Butterfly Network) and a water-based coupling medium, aiming to deliver MRI-comparable imaging quality at a fraction of the cost, time, and complexity of traditional scanners. Midjourney has reportedly committed over $74 million to the effort.

The company's vision is to make whole-body screening as casual as a trip to the spa: it plans to open its first "Midjourney Spa" in 2027, where patients would get a 60-second full-body scan without radiation exposure. The prototype was unveiled publicly in mid-2026 and has generated significant industry buzz, though it has also drawn skepticism from radiologists and medical professionals about whether ultrasound can truly match MRI-level diagnostic detail.
