New AI Algorithm Detects Signs of Life on Mars with 90% Accuracy

New AI algorithm can detect signs of life on other planets with 90% accuracy. Scientists want to send it to Mars.
Algorithm relies on the idea that chemistry of life differs from inanimate world. It can spot subtle differences in molecular patterns.
Algorithm was trained on 134 samples, including fossils. It successfully identified biotic vs abiotic samples.
Method can be used to study 3.5 billion year old rocks in Australia that may contain Earth's oldest fossils.
If proven effective on early Earth samples, algorithm could be embedded in sensors on rovers exploring Mars and icy moons.

AI System Predicts Smells of Molecules, Opening Door to Digitizing Odors

Scientists have trained an artificial intelligence (AI) system to create an odor map that visually displays the relationships between different smells and accurately predicts what a new molecule would smell like, with the AI's descriptions outperforming those of human panelists in most cases.
