Conventional wisdom holds that as coral reefs die, they become underwater barrens dominated by algae. In some places that’s true — but elsewhere, they’re following a different trajectory.

New catalysts made from abundant and inexpensive materials could lead to a commercially viable way to convert carbon dioxide into plastics and other useful products.

Eating protein-rich algae, insects and lab-cultured meats is more than a dietary fad: it could bring benefits for our health and the environment.

A genetic tweak that makes photosynthesis more efficient in plants could increase crop yields by 40%, and help feed millions more people around the globe.

Certain salt-loving microorganisms could eat seaweed and produce biodegradable plastics in a sustainable fashion.

Manufacturing bricks is carbon-intensive and creates toxic air pollution. Recycling treated solid waste to make bricks would keep some of this waste from landfills and reduce brick-making's emissions.

Fast fashion is a bane on the environment. Now researchers have come up with a way to turn discarded clothes into fire- and water-proof building materials.

In 2016 alone, humans consumed almost 70 billion chickens globally. These huge numbers are part of the reason why the biomass of humans and domesticated animals, combined, now outweighs that of all wild vertebrates on earth.
