What values does an AI show when talking to real people? Anthropic took a deep dive into its AI, Claude.
They analyzed 700,000 real conversations to see if Claude actually acts "helpful, honest, and harmless."
Good news: Claude mostly aligns with its goals.

This study helps us understand how AI makes judgments and whether it aligns with human values in the real world.
Key point: Evaluating AI values isn't just for the lab. We need ways to check them during actual use, not just pre-release.

This dirt formwork is "infinitely recyclable," according to the researchers. Just dirt turned into a useful tool.
Plus, 3D printing soil makes it easier to create custom, complex shapes optimized to use less concrete.

After success with small doses, they're now testing larger amounts on volunteers. Mild side effects reported so far.
If trials confirm safety and effectiveness, it could be in practical use around 2030. Other teams are also developing similar artificial oxygen carriers.

But avoiding Toxoplasma is key: it’s risky in pregnancy, for low immunity, and a top cause of US foodborne illness deaths.
Protect yourself: cook meat properly, thoroughly wash produce, be careful with cat litter (especially if high-risk), and always wash your hands well.
