Asymmetric interactions between molecules may serve as a stabilizing factor for biological systems. A new model reveals this regulatory role of non-reciprocity. The scientists aim to understand the ...

Pesticides and disinfection by-products are widely detected together in treated drinking water at trace levels worldwide. Both groups are associated with long-term health risks, including cytotoxicity ...

How do complex mixtures of chemicals affect our health? New research has shown that chemicals that occur in complex mixtures and in concentration ratios as found in humans act together. Even if the ...

A homogeneous mixture is also known as a solution. It is a substance composed of two or more substances that are distributed uniformly at a molecular level or microscopic. In easier terms, homogeneous ...

Students learn to identify various methods for separating mixtures to define density. Matter: Separation of Mixtures: Students learn to identify various methods for separating mixtures, to define ...

Food additive mixtures are an everyday feature of our diets, especially through ultra-processed foods. Until recently, safety evaluations of these additives have been conducted substance by substance ...

Seeding rates for native warm-season grass and forb mixtures (NWSG) have changed drastically over time. In the past, native grasses were planted without forbs at rates exceeding 10 lbs/ac. This may be ...

Join us in Edinburgh in May 2019 for this addition to our Faraday Discussion series. For over 100 years and 300 meetings, Faraday Discussions have been the forefront of physical chemistry. Many of ...

Origin-of-life researchers have usually studied the potential of pure starting materials, but messy chemical composites may kick-start life more effectively. Scientists studying how life arose from ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...
