Asteroid Ryugu has a rich complement of organic molecules, according to a NASA and international team's initial analysis of a sample from the asteroid's surface delivered to Earth by Japan's Hayabusa2 spacecraft. The discovery ...

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.

The origin of life: A paradigm shift

According to a new concept by LMU chemists led by Thomas Carell, it was a novel molecular species composed out of RNA and peptides that set in motion the evolution of life into more complex forms.

Scientists discover new 'origins of life' chemical reactions

Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by a vast ocean. Over the course of millions of years, in that primordial soup, life emerged. Researchers have long theorized ...

Evolution reveals missing link between DNA and protein shape

Fifty years after the pioneering discovery that a protein's three-dimensional structure is determined solely by the sequence of its amino acids, an international team of researchers has taken a major step toward fulfilling ...
