Commentary on an article by @sebastienviscardy.bsky.social, me and Kevin Zahnle arguing how Curiosity rover detections of methane are more likely methane contamination inside the rover than in the martian atmosphere.

my book, “Astrobiology: A Very Short Introduction” is now published in Chinese and available to 1.2B people for whom Chinese is a 1st or 2nd language (1st Ed with updates, Yilin Press, Nanjing). Coming soon: 2nd Ed. (OUP) in English in 2026/7, with updates on planetary science, origin of life, etc.

Origin of biological homochirality by crystallization of an RNA precursor on a magnetic surface
Homochirality was achieved by the spin-selective crystallization of a racemic RNA precursor on a magnetite surface.
My 2 cents: The CISS effect (chirality induced spin selectivity) is the best answer to date. It empirically produces homochirality in biologically-relevant molecules unlike previous ideas with little/no feasibility. Underlying theory of CISS remains TBD. See, e.g., www.science.org/doi/full/10....

At the same time, Dirac saw defining what exactly is a measurement and what exactly is associated collapse as difficult problems that future theory needed to resolve and perhaps turn into quite different problems. I’ll happily defer to Dirac.

I was educated with the Bohr interpretation that an observation is the interaction of a quantum phenomenon (e.g. an electron) with a classical apparatus, which doesn’t require a conscious observer. The quantum measurement ends when macroscopically recorded, which doesn’t require a mind.

I’m having trouble seeing how your examples, Ray, are qualitatively different from Schrödinger’s Cat & its various proposed solutions. This is a problem from 90 years ago.

Haas, Tutolo & Catling 2025. A phosphorus budget of soda lakes finds major biological sinks, implying abundant phosphate-availability at the origin of life.
My group's most recent paper: We quantified phosphorus fluxes in soda lakes, showing that without biology, soda lakes worldwide would have phosphate levels suitable for prebiotic synthesis of RNA. This answers a 70-year-old “phosphate problem of the origin of life”
