A personalized AI tool might help some reach end-of-life decisions—but it won’t suit everyone
—Jessica Hamzelou
This week, I’ve been working on a piece about an AI-based tool that could help guide end-of-life care. We’re talking about the kinds of life-and-death decisions that come up for very unwell people.
Often, the patient isn’t able to make these decisions—instead, the task falls to a surrogate. It can be an extremely difficult and distressing experience.
A group of ethicists have an idea for an AI tool that they believe could help make things easier. The tool would be trained on information about the person, drawn from things like emails, social media activity, and browsing history. And it could predict, from those factors, what the patient might choose. The team describe the tool, which has not yet been built, as a “digital psychological twin.”
There are lots of questions that need to be answered before we introduce anything like this into hospitals or care settings. We don’t know how accurate it would be, or how we can ensure it won’t be misused. But perhaps the biggest question is: Would anyone want to use it? Read the full story.

+ The messy morality of letting AI make life-and-death decisions. Automation can help us make hard choices, but it can’t do it alone. Read the full story.
+ …but AI systems reflect the humans who build them, and they are riddled with biases. So we should carefully question how much decision-making we really want to turn over to.
+ Technology that lets us “speak” to our dead relatives has arrived. But are we ready? Read the full story.

Toys can change your life
Toys, games, and even amusement park rides can change how young minds view science and math.
The Slinky has long served teachers as a medium for demonstrating longitudinal (soundlike) waves and transverse (lightlike) waves. A yo-yo can be used as a gauge (a “yo-yo meter”) to observe the forces on a roller coaster. Marbles employ mass and velocity. Even a simple ball offers insights into the laws of gravity.
And, over the last several decades, evidence has emerged that childhood play can shape our future selves: the skills we develop, the professions we choose, our sense of self-worth, and even our relationships. Read the full story.

The big story
Inside the experimental world of animal infrastructure
June 2022
Around the world, cities are building a huge variety of structures intended to mitigate the impacts of urbanization and roadbuilding on wildlife. The list includes green roofs, tree-lined skyscrapers, living seawalls, artificial wetlands, and all manner of shelters and “hibernacula.”
But the data on how effective these approaches are remains patchy and unclear. That is true even for wildlife crossings, the best-studied and most heavily funded example of such animal infrastructure. Read the full story.
