Hydrogen bonds directly detected for the first time

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel's Swiss Nanoscience Institute network ...

DNA is only one among millions of possible genetic molecules

Biology encodes information in DNA and RNA, which are complex molecules finely tuned to their functions. But are they the only way to store hereditary molecular information? Some scientists believe life as we know it could ...

New evidence that comets could have seeded life on Earth

(Phys.org) —It's among the most ancient of questions: What are the origins of life on Earth? A new experiment simulating conditions in deep space reveals that the complex building blocks of life could have been created ...

Scientists say the 'R' in RNA may be abundant in space

New research suggests that the sugar ribose - the "R" in RNA - is probably found in comets and asteroids that zip through the solar system and may be more abundant throughout the universe than was previously thought.

How RNA formed at the origins of life

A single process for how a group of molecules called nucleotides were made on the early Earth, before life began, has been suggested by a UCL-led team of researchers.
