How do corals make the most of their symbiotic algae?

Corals depend on their symbiotic relationships with the algae that they host. But how do they keep algal population growth in check? The answer to this fundamental question could help reefs survive in a changing climate.

Who controls whom: Algae or sea anemone?

Bleached anemones—those lacking symbiotic algae—do not move toward light, a behavior exhibited by healthy, symbiotic anemones. Published in Coral Reefs, this finding from Carnegie's Shawna Foo, Arthur Grossman, and Ken ...

Bio-inspired nano-catalyst guides chiral reactions

Many medicines are twisted molecules with two mirror image versions, but the body uses only one. Inspired by photosynthetic bacteria, a team at the University of Michigan built a catalyst that guides chemical reactions toward ...

What delayed Earth's oxygenation?

Powering a massive biosphere on Earth, photosynthesis is the light-mediated reaction that converts carbon dioxide and water to carbohydrates and oxygen. About 2.3 billion years ago, this reaction led to a dramatic oxygenation ...

How plant cells neutralize the potential for self-harm

Photosynthesis makes our atmosphere oxygen-rich and forms the bedrock of our food supply. But under changing or stressful environmental conditions, the photosynthetic process can become unbalanced, resulting in an excess ...
