An ancient enzyme helps some land and freshwater bacteria produce a building block of plastic when they metabolize sulfur

By drawing heat radiated from a person's body rather than cooling and dehumidifying air, radiant-cooling panels could cool people in outdoor spaces using little energy

Naturally available compounds in the peels are a benign alternative to the harsh chemicals used today to extract valuable metals from discarded batteries

Sunlight-absorbing sheets that make fuel from carbon dioxide and water could reduce greenhouse gas in the atmosphere, and our dependence on fossil fuels

Modified E. Coli bacteria convert a chemical derived from plant lignin into a key ingredient for making nylon

Using the red pigment in bricks as a chemical reactant, researchers fill brick pores with conductive plastic so they can store energy

Recycled road-making material could keep tons of waste out of landfills and reduce carbon dioxide emissions

The lockdown in India gave a unique chance to measure how drastic drops in air pollution can increase solar panel output

The high-efficiency system promises a way to capture the full spectrum of sunlight for a low cost.

With some simple chemical tweaks, cooling paint could more effectively reflect solar energy under a glaring sun.
