Generative AI is an energy hog. Is the tech worth the environmental cost?
Generative AI and the hype around it has rung in excitement and alarm bells this year. Here’s how to consider climate, energy and AI's intersection.
- Neuroscience
Electronic ‘tattoos’ offer an alternative to electrodes for brain monitoring
A standard EEG test requires electrodes that come with pitfalls. A spray-on ink, capable of carrying electrical signals, avoids some of those.
- Artificial Intelligence
Here’s why turning to AI to train future AIs may be a bad idea
If future AI models are trained on AI-generated content, they could end up producing more bias and nonsense, researchers caution.
