Protein family shows how life adapted to oxygen

Cornell scientists have created an evolutionary model that connects organisms living in today's oxygen-rich atmosphere to a time, billions of years ago, when Earth's atmosphere had little oxygen—by analyzing ribonucleotide ...

Better understanding of cellular metabolism with the help of AI

Metabolism is essential to all living organisms, and modeling the chemical reactions that sustain life is no easy task. Now, EPFL scientists have released REKINDLE, a deep-learning process that is paving the way for more ...

New upcycling system for commercial polyesters

While plastics or synthetic polymers have many useful properties, their mismanagement has resulted in widespread pollution that chokes up our ecosystems. As a solution to this, many synthetic polymers are sent for reprocessing ...

Study finds high levels of PFAS in school uniforms

In yet another example of the prevalence of the hazardous chemicals known as PFAS (per- and polyfluoroalkyl substances) in consumer products, industrial products and textiles, researchers have found notably high levels in ...

A closer look at third-hand smoke and its risks

Using state-of-the-art techniques, researchers have gained a better understanding of the complex mix of hazardous chemicals in third-hand smoke—the residual contamination from cigarette smoking—which can linger long after ...

EPA to designate 'forever chemicals' as hazardous substances

The Environmental Protection Agency moved Friday to designate two "forever chemicals" used in cookware, carpets and firefighting foams as hazardous substances, a step that would clear the way for quicker cleanup of the toxic ...
