Artificial intelligence in biomedicine: A key to analyzing millions of individual cells
Our bodies are made up of around 75 billion cells. But what function does each individual cell perform and how greatly do a healthy person's cells differ from those of someone with a disease? To draw conclusions, enormous quantities of data must be analyzed and interpreted. For this purpose, machine learning methods are applied. Researchers have now tested self-supervised learning as a promising approach for testing 20 million cells or more.

Imagining the physics of George R.R. Martin's fictional universe
Researchers have derived a formula for viral behavior in the Wild Cards, a science fiction series written by a collection of authors about an alien virus called the Wild Card that mutates human DNA. The formula he derived is a Lagrangian formulation, which considers the different ways a system can evolve. It's also a fundamental physics principle, which also makes the fictional example a powerful teaching tool.
