A new catalyst may well catalyze a shift to greener chemistry. Chemists from Yokohama National University have successfully developed innovative catalysts containing two noble metals that demonstrate remarkable efficiency in ester-producing chemical.....»»
How (apparently) identical animals can be completely different species
Logically speaking, you would think that animals who appeared to be the same—even if they were found in different parts of the world—would belong to the same species, and that they would share the same genome. However, our recent study has found.....»»
Nitrogen-using bacteria can cut farms’ greenhouse gas emissions

Chocolate"s tasty flavors might pose a health risk in other desserts
What makes chocolate taste and smell so delicious? Chemistry, of course. A variety of molecules work together to create that unmistakable aroma, but those same molecules might carry some unwanted health effects if there are too many around. According.....»»
To what extent are pharmaceutical and illicit drugs contaminating city rivers?
In research published in Environmental Toxicology & Chemistry, investigators sampled water from 19 locations across the Hudson and East Rivers in 2021 and 2022 to identify and quantify the prescribed pharmaceuticals and drugs of abuse that are making.....»»
Scientists uncover a multibillion-year epic written into the chemistry of life
The origin of life on Earth has long been a mystery that has eluded scientists. A key question is how much of the history of life on Earth is lost to time. It is quite common for a single species to "phase out" using a biochemical reaction, and if th.....»»
