A hidden pigment helps ocean algae harness sunlight without getting burned—and it may hold clues for better solar tech.

Under the sea, green algae have evolved a clever way to handle too much sunlight. Scientists found that a special pigment called siphonein acts like a natural sun shield, protecting the algae’s ...

Curved molecules that absorb sunlight, store the energy, and re-release it as heat are pushing the boundaries in solar thermal storage technology. The anthracene systems, derived from a by-product of ...

The sun can provide limitless heat for buildings and industrial processes. But using that heat on demand means capturing and storing solar thermal energy for when the sun isn’t shining. Researchers ...
