Caught in the actinium

Caught in the actinium
2024-07-15
The element actinium was first discovered at the turn of the 20th century, but even now, nearly 125 years later, researchers still don’t have a good grasp on the metal’s chemistry. That’s because actinium is only available in extremely small amounts and working with the radioactive material requires special facilities. But to improve emerging cancer treatments using actinium, researchers will need to better understand how the element binds with other molecules. In a new study led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), ...

When to trust an AI model

2024-07-12
CAMBRIDGE, MA – Because machine-learning models can give false predictions, researchers often equip them with the ability to tell a user how confident they are about a certain decision. This is especially important in high-stake settings, such as when models are used to help identify disease in medical images or filter job applications. But a model’s uncertainty quantifications are only useful if they are accurate. If a model says it is 49% confident that a medical image shows a pleural effusion, then 49% of the time, the model should be right. MIT ...
