Startup Switch Bioworks is taking a new approach: using a genetic switch that allows microbes to establish themselves and grow before shifting into nitrogen-producing mode.

The company is currently trialing its product in six US states. And, although it’s too early to say exactly how well the approach works in the field, its modeling suggests microbes could eventually replace about 50% of synthetic fertilizer.

The Hugging Face hack could indicate cultural issues at OpenAI

OpenAI has released a postmortem technical report on last month’s Hugging Face hack. But it’s missing a critical dimension: the role company culture may have played.

That’s all the more concerning because the report’s few references to human error suggest OpenAI’s culture played a big role. Its employees noticed models communicating with one another during training and evaluation, yet allowed them to continue. At multiple points, they either failed to raise the alarm or were not heard when they did.

“All these different failures are all pointing in the same direction, which is that the safety culture at OpenAI doesn’t exist or is anemically weak,” says Zvi Mowshowitz, a popular AI safety writer.
