Key building block for organic molecules discovered in meteorites

Scientists from Japan and the U.S. have confirmed the presence in meteorites of a key organic molecule which may have been used to build other organic molecules, including some used by life. The discovery validates theories ...

Creating self-constructed folded macrocycles with low symmetry

The synthesis and self-organization of biological macromolecules is essential for life on earth. Ludwig Maximilian University of Munich chemists now report the spontaneous emergence of complex ring-shaped macromolecules with ...

Building blocks of life can form long before stars

An international team of scientists have shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh conditions that govern chemistry in space.

The birth of a bacterial tRNA gene

Translation is the process by which genetic information is converted into proteins, the workhorses of the cell. Small molecules called transfer RNAs (tRNAs) play a crucial role in translation; they are the adapter molecules ...

In the beginning, there was sugar

Organic molecules formed the basis for the evolution of life. But how could inorganic precursors have given rise to them? LMU chemist Oliver Trapp now reports a reaction pathway in which minerals catalyze the formation of ...
