Purdue University researchers have found a way to use machine learning for reducing that time to just a few days. Their study is one of the first demonstrations of using machine learning to discover physical laws from data.

A team of engineers from Purdue University, Air Squared Inc., and Whirlpool Corporation is working on building a fridge for zero gravity that operates in different orientations and just as well as the one in your kitchen, giving astronauts access to longer-lasting and more nutritious food.

New paint formulation could help buildings rely less on air conditioning.

The paint would not only send heat away from a surface but also away from Earth into deep space where heat travels indefinitely at the speed of light.
