A prebiotic route to DNA
DNA may have appeared on Earth earlier than has hitherto been assumed. LMU chemists led by Oliver Trapp show that a simple reaction pathway could have given rise to DNA subunits on the early Earth.

Discovery of RNA transfer through royal jelly could aid development of honey bee vaccines
Researchers have discovered that honey bees are able to share immunity with other bees and to their offspring in a hive by transmitting RNA 'vaccines' through royal jelly and worker jelly. The jelly is the bee equivalent ...

Cleaning up the clutter: How proto-biology arose from the prebiotic clutter
Just like the mythical creation stories that depict the formation of the world as the story of order from chaos, the early Earth was home to a chaotic clutter of organic molecules from which, somehow, more complex biological ...

Cellular stress at the movies: Biochemists illuminate a key survival mechanism in cells
Much like our fight-or-flight response, our cells also have a stress autopilot mode. An oxygen dropoff, overheating, or an invading toxin can trigger the cellular stress response – a cascade of molecular changes that are ...
