When my dad was sick, I started Googling grief. Then I couldn’t escape it.

—Tate Ryan-Mosley, senior tech policy reporter

I’ve always been a super-Googler, coping with uncertainty by trying to learn as much as I can about whatever might be coming. That included my father’s throat cancer.

I started Googling the stages of grief, and books and academic research about loss, from the app on my iPhone, intentionally and unintentionally consuming people’s experiences of grief and tragedy through Instagram videos, various newsfeeds, and Twitter testimonials.

Yet with every search and click, I inadvertently created a sticky web of digital grief. Ultimately, it would prove nearly impossible to untangle myself from what the algorithms were serving me. I got out—eventually. But why is it so hard to unsubscribe from and opt out of content that we don’t want, even when it’s harmful to us? Read the full story.

AI models spit out photos of real people and copyrighted images

The news: Image generation models can be prompted to produce identifiable photos of real people, medical images, and copyrighted work by artists, according to new research. 

How they did it: Researchers prompted Stable Diffusion and Google’s Imagen with captions for images, such as a person’s name, many times. Then they analyzed whether any of the generated images matched original images in the model’s database. The group managed to extract over 100 replicas of images in the AI’s training set.

Why it matters: The finding could strengthen the case for artists who are currently suing AI companies for copyright violations, and could potentially threaten the human subjects’ privacy. It could also have implications for startups wanting to use generative AI models in health care, as it shows that these systems risk leaking sensitive private information. Read the full story.

The big story

Companies hoping to grow carbon-sucking kelp may be rushing ahead of the science

September 2021

One of the hottest climate change solutions that companies are touting is that kelp could suck up carbon dioxide and store it away in the depths of the sea, effectively reversing climate change.

But scientists are still grappling with fundamental questions about this approach. How much kelp can we grow? What will it take to ensure that most of the seaweed sinks to the bottom of the ocean? And how much of the carbon will stay there long enough to really help the climate? Read the full story.
