Flavorings containing benzaldehyde can develop benzene under the influence of light - In 2013, the Stiftung Warentest found harmful benzene in drinks with cherry flavor.
In the production of compounds, chemists have the fundamental goal of finding strategies that are most selective and avoid waste products.
Z-form nucleic acids are double-stranded DNA and RNA molecules with an unusual left-handed double helix structure, as opposed to the classical right-handed Watson-Crick double helix. Z-nucleic acids were discovered more than 40 years ago, but their biological function has remained poorly understood.
More and more, people are using internet forums as first place to look for information on health issues.

Scientists from Freiburg's two Excellence Institutions Centre for Biological Signalling Studies (BIOSS) and Spemann Graduate School of Biology and Medicine (SGBM) have discovered a new signaling path in cells: a mechanism which enables the transport of proteins into mitochondria to be adjusted depending on the current metabolic state of the cell.
Freiburg Biochemist Describes Newly Discovered Processes in Production of Proteins in 'Nature' Freiburg, 07.01.2011 The chaperone ZRF1 helps the ribosome to regulate protein synthesis. A new study shows that it also participates in the regulated translation of DNA segments into transcripts in the nucleus.
