The Study
Lipid Synthesis Under Hydrothermal Conditions by Fischer- Tropsch-Type Reactions
This experiment showed that if you heat up some simple chemicals in a jar, you can make stuff that looks like the building blocks of life. But it doesn’t mean that’s how life started on Earth or Mars — it just shows one way it *could* happen in a lab.
Analysis score
Maximum 0 for a computational/algorithm study.
Where the score came from
Scientists heated simple acids in a metal pot like a pressure cooker and got oily chemicals that look like the ones in animal fats and plants — even though no living thing was involved.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — this shows life’s building blocks might form naturally in hot ocean vents without biology.
- 2Heated formic or oxalic acid at 175°C for 2–3 days → made lipids with carbon chains from 2 to over 35 atoms long.

If you heat up formic acid or oxalic acid in a metal container at a high temperature for a couple of days, it can turn into a bunch of oily, waxy, or fatty substances similar to those found in living things.
If you heat up two simple acids—formic acid and oxalic acid—in a hot, pressurized water environment, they both make the same kind of fatty molecules, so either one could work as a starting material to make these lipids.
Scientists used carbon atoms with a special tag to track where the fats in their experiment came from — and they found the fats came from the tagged chemicals they added, not from dirt or other random stuff.
Under hot, watery conditions similar to those deep under the ocean, certain chemical reactions can make oily molecules similar to those found in living things — from very small ones to really big ones, including both plain oils and oils with oxygen in them.
In this experiment, scientists made some oily substances that include simple carbon chains and others with oxygen in them—like alcohols and acids—showing they created a messy mix of organic chemicals without using living things.
