The Immortal Life of Henrietta Lacks VS Project Hail Mary
Verdict BUY IT BUY IT
The Reality These specific scientific claims are independently confirmed by medical and research institutions, not just the book's own framing. The NIH's own history of HeLa cells confirms their unprecedented ability to divide indefinitely (traced to Lacks's cells being infected with HPV-18, which disabled the biological checks that normally limit cell division) and their direct role in developing the polio vaccine and enabling landmark work in cloning, gene mapping, and in vitro fertilization. HeLa cells remain in active use in labs worldwide today, and the book's account of the ethical circumstances -- cells taken without Lacks's knowledge or consent, standard practice at the time but a genuine historical wrong now widely acknowledged -- is corroborated by contemporary NIH and scientific-journal commentary. Real reader reception backs up the reputation: 179 independent Open Library ratings average 4.50/5, with fewer than 3% rating it 2 stars or below. But the book's central scientific conceit — how the protagonist teaches an alien species human language from scratch — was the specific target of a dedicated Ars Technica critique, which examined that mechanic in depth and found it the book's least scientifically rigorous element, even as its orbital mechanics and chemistry hold up better. A film adaptation (Amazon MGM Studios) is real and in production, with Polygon covering a real marketing controversy around its trailer — genuine current relevance beyond the book itself.
SHORT ANSWER
The Immortal Life of Henrietta Lacks: The book's core scientific claims about HeLa cells -- their indefinite division and their direct role in the polio vaccine and other major breakthroughs -- are independently confirmed by the NIH's own official history of the cell line.
Project Hail Mary: Real reader reception for Project Hail Mary is strong (4.50/5 across 179 independent Open Library ratings), and most of its science holds up — but Ars Technica published a specific critique questioning the scientific rigor of the book's central language-learning plot device, the one part of its 'hard sci-fi' framing that doesn't fully hold up.
