X-shaped radio galaxies might form more simply than expected

When astronomers use radio telescopes to gaze into the night sky, they typically see elliptical-shaped galaxies, with twin jets blasting from either side of their central supermassive black hole. But every once in a while—less ...

'Forever chemicals' destroyed by simple new method

PFAS, a group of manufactured chemicals commonly used since the 1940s, are called "forever chemicals" for a reason. Bacteria can't eat them; fire can't incinerate them; and water can't dilute them. And, if these toxic chemicals ...

Upcycling polyester could reduce plastic waste

Less than 10% of the 380 million metrics tons of annually produced plastics are currently recycled in the U.S., creating a global environmental threat caused by plastic production and the absorption of millions of tons of ...

Methane-eating bacteria convert greenhouse gas to fuel

Methanotrophic bacteria consume 30 million metric tons of methane per year and have captivated researchers for their natural ability to convert the potent greenhouse gas into usable fuel. Yet we know very little about how ...

Bacteria upcycle carbon waste into valuable chemicals

Bacteria are known for breaking down lactose to make yogurt. Now researchers led by Northwestern University and LanzaTech have harnessed bacteria to break down waste carbon dioxide (CO2) to make valuable industrial chemicals.

New DNA computer assesses water quality

Northwestern University synthetic biologists have developed a low-cost, easy-to-use, hand-held device that can let users know—within mere minutes—if their water is safe to drink.

Study reveals how to break symmetry in colloidal crystals

Nature keeps a few secrets. While plenty of structures with low symmetry are found in nature, scientists have been confined to high-symmetry designs when synthesizing colloidal crystals, a valuable type of nanomaterial used ...
