Novel synthesis process for sustainable production of small molecules
Researchers at Ruhr University Bochum, Germany, have discovered a new synthetic pathway with which they can produce a specific organic compound from the simple molecule carbon monoxide (CO), namely anionic ketenes. These were previously only known as.....»»
A legume locus stimulates promiscuous interaction with soil bacteria
While promiscuity among humans is often scorned, symbiotic promiscuity can be a sign of excellent teamwork in other species. Plant growth, especially in legumes, flourishes through mutualistic interactions with soil bacteria, commonly known as rhizob.....»»

Measuring times in billionths of a billionth of a second
How fast do electrons inside a molecule move? Well, it is so fast that it takes them just a few attoseconds (a billionth of billionth of a second) to jump from one atom to another. Blink and you missed it—millions of billions of times. So measuring.....»»
