NASA's OSIRIS-REx mission found ingredients for DNA and RNA on the asteroid Bennu. The discovery shows asteroids could seed planets with the precursors for life. It's also more evidence that life ...

This figure illustrates key molecules and minerals discovered in samples of near-Earth asteroid (101955) Bennu, which were delivered to Earth by NASA’s OSIRIS-REx mission in September 2023. Bennu is a ...

WASHINGTON (Reuters) - Rock and dust samples retrieved by NASA from the asteroid Bennu exhibit some of the chemical building blocks of life, according to research that provides some of the best ...

Life on Earth relies on molecular building blocks to make DNA and proteins. Scientists have long wondered how prevalent these precursors were at the birth of our solar system. A sample of dust and ...

DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

The newest DNA sequencing technology from Swiss multinational Roche doesn’t measure DNA directly but in fact analyzes a different polymer altogether. The technology is not yet available for sale, but ...

Polyethyleneimines (PEIs) are extensively researched as non-viral vectors for gene and medication delivery because of their capacity to condense nucleic acids into nanoparticles known as polyplexes. 1 ...

NASA probed an asteroid and found an ancient repository of ingredients for life. The findings, published in two papers in the journals Nature and Nature Astronomy on Wednesday, point to a missing link ...
