Can light restore aspects of sight? Can recalling a cold experience change an animal's metabolism? And what can ghost particles and mirror-image molecules tell us about the universe?

Lester Nare and Krishna Choudhary follow up on our 2026 Nobel Prize episodes with research building on optogenetics, IceCube and molecular handedness. We unpack an early human vision-restoration trial, cold-memory experiments in mice, cosmic neutrino flavors, and a tiny electrical sensor for distinguishing left- and right-handed amino acids.

Plus: how the Nobels work, our follow-up on the Nobel chemistry illustration, a brief look at neutrino Earth tomography, and why fundamental research matters. Which discovery would you like us to explore next?

EDITORIAL NOTES
The vision trial was small and exploratory. The cold-memory findings discussed are from mice.

On-screen clarifications:
16:53 Both eyes were profoundly visually impaired; the worse-seeing eye was treated.
19:57 The untreated eye was patched during testing, not a normal-vision control.
54:41 Neutrino event rates depend on energy and selection, not just detector volume.
1:05:47 Flavor identification efficiency is distinct from interaction probability; both depend on energy.
1:13:35 Other astronomy-related Nobels include 2017 (LIGO) and 2019 (cosmology/exoplanets).
1:18:00 The LHC at CERN enabled the Higgs discovery; CERN itself was founded in 1954.
1:44:25 Both enantiomers produce current signals; waveform features distinguish them.
1:46:42 Murchison is a meteorite. Diego de Almagro and North of Antofagasta are soil sites.
1:47:40 The sensor study reports mixed agreement and limitations, not uniformly negative results.
1:49:00 Phobos is a Martian moon; a captured-asteroid origin is a hypothesis.
