“A strand of RNA just 45 nucleotides long has been discovered to perform two key reactions required for self-replication. The molecule, which is a kind of RNA enzyme, offers a tantalising clue towards understanding the origin of life, namely how non-living chemistry on prebiotic Earth started to self-replicate and evolve.”

The origin of life has been debated for centuries. The most accepted theory is known as the primordial soup, or abiogenesis.

Sulfur exacts a brutal toll for its extraction, but guides the electricity that drives all life.

My cynical side thinks that this is really good press for NASA, and they are pushing this narrative to maintain funding by making themselves seem extremely important. My less cynical side thinks that this is probably just some nerds getting excited about finding alien lifeforms. I'm just pretty skeptical. Just because they haven't found a tidy chemical/geological explanation for it, doesn't justify (to me) jumping to "life probably existed on Mars". n/n #NASA #rocks #abiogenesis #aliens

Science has a fairly good idea about how Earth's life could have started, but recreating that process has remained elusive. Now, another step in the chain appears to be coming into view.

The last universal common ancestor lived off #hydrogen gas and carbon dioxide, boasted a genome as large as that of some modern #bacteria, and already had an immune system

Its genomic complexity suggests that it was one of many lineages living about 4.2 billion years ago, a turbulent time early in Earth’s history and long thought too harsh for life to flourish.

#Life evolved from a simple replicator into something resembling modern microbes very quickly.

Ancient #Earth was nothing like our current home.

It was a much more hostile place; rich in metallic iron with an #atmosphere containing hydrogen and methane.

These molecules contain an important clue to how #life was initially formed.

When exposed to solar #ultraviolet radiation, they undergo a chemical reaction that produces organics: precursors to essential biomolecules, such as amino acids and nucleic acids.

There're two main theories about origin of🌱 #Life on Earth: #Aristotle's 🧬⚡#aBioGenesis and Hermann Richter's🧬☄️#PanSpermia (1865)
If #PanSpermia was right and #Mars was capable of supporting life, how come there is no life on #Mars?
