An anomaly-detection model developed by SMART utilizes machine learning to quickly detect microbial contamination.

MIT scientists estimate that oxygenic photosynthesis — the ability to turn light and water into energy, releasing oxygen— first evolved on Earth between 3.4 and 2.9 billion years ago.

Zeroing in on the origins of Earth’s “single most important evolutionary innovation”

A new study shows oxygenic photosynthesis likely evolved between 3.4 and 2.9 billion years ago.

Bench, bath and beyond: Transform your apartment into a yeast lab, and have fun doing it!

In quarantine in my own home, I re-discovered a centuries-old truth: yeast will appear and grow anywhere. With a bit of intuition and a lot of patience, you too can transform any apartment into a lab to grow your pet yeast in!
