By rearing frogs with parents — or foster parents — of different colors, biologists discovered that behavior in response to color may be more important than genetics in the evolution of new species.
Read moreAn international research team has used nanoparticles to convert carbon dioxide into valuable raw materials. Scientists have adopted the principle from enzymes that produce complex molecules in multi-step reactions. The team transferred this mechanism to metallic nanoparticles, also known as nanozymes. The chemists used carbon dioxide to produce ethanol and propanol, which are common raw materials for the chemical industry.
Read moreThe origin of the tin used in the Bronze Age has long been one of the greatest enigmas in archaeological research. Now researchers have solved part of the puzzle. They were able to proof that tin ingots found at archaeological sites in Israel, Turkey, and Greece do not come from Central Asia, as previously assumed, but from tin deposits in Europe.
