Why All Life on Earth Is Left-Handed
Original: The 50/50 Paradox: Why All Life on Earth is Left-Handed
All known life uses left-handed amino acids, a mystery known as the 50/50 paradox: chemically, molecules should form in equal mirror-image proportions, yet biology overwhelmingly chose one. Science communicator Anton Petrov is drawing large attention with an explainer covering leading hypotheses, from meteorite-borne asymmetries to early chemistry on early Earth, and why the puzzle still has no settled answer.
Why now: A popular science explainer on the origin of life's molecular handedness is resonating widely right now.
