Making complex molecules often means joining smaller chemical building blocks together, a process facilitated by catalysts, compounds that make such reactions possible or speed them up without being consumed themselves. Many widely used reactions also require chemists to modify their starting molecules before joining them. These added chemical "handles" make the molecules reactive, but preparing them means extra steps and, often, additional waste.

Light-controlled brake makes random molecular motion 300,000 times slower
Molecules are never still. Driven by thermal energy, they are constantly moving through space, while their individual parts also rotate relative to one another. Scientists at IOCB Prague have now shown that random motion within a molecule can be dramatically suppressed. Using lig
