Analyze This: A new fabric mimics polar bears’ pelts for warmth
With layers that work like polar bears’ skin and fur, a material absorbs light and keeps it from escaping.
- Tech
Nanocrystal ‘painted’ films may someday help relieve summer heat
The rainbow palette and cooling powers of new plant-based films comes from their microscopic surface patterns of tiny crystals.

Think of this new tech as sunglasses for our windows
Keeping buildings cool can use a lot of energy. Thanks to quantum computing, engineers designed a coating to cut the warming light that enters windows.
- Climate
Creating less new stuff could greatly help Earth’s climate
Instead of throwing unneeded things away, scientists recommend moving to a cycle of reducing, reusing, repairing and remaking old things into new ones.
