8.5 US-German Trio Wins 2026 Nobel Prize in Medicine for Optogenetics¶
Karl Deisseroth, Peter Hegemann, and Georg Nagel won the 2026 Nobel Prize in Physiology or Medicine for discovering light-gated ion channels and developing optogenetics, a technique combining optical and genetic methods to stimulate neurons non-invasively. Optogenetics has revealed neural circuits governing memory, emotion, and behavior, with clinical applications for treating blindness, depression, Parkinson's disease, and other neurological disorders.
- Three recipients: Deisseroth (Stanford), Hegemann (Humboldt), Nagel (Würzburg)
- Optogenetics uses light to control individual neurons within milliseconds
- Potential applications: blindness restoration, depression, Parkinson's, epilepsy, dementia
- Prize worth 12 million Swedish kronor (~€1M or $1.2M)
- Awards presentation December 10, 2026 in Stockholm
- Discovered channelrhodopsin: light-sensitive protein from algae
- Enables neuron control within milliseconds using blue light pulses
- Maps neural circuits governing behaviors, memories, feelings, disease states
- Deisseroth HHMI Investigator since 2014; 36th current/alumni HHMI Nobel laureate
- Optogenetics now used worldwide; transformed neuroscience research

7.5 Researchers Identify MEK Pathway to Combat T-Cell Exhaustion in Cancer Therapy¶
Memorial Sloan Kettering researchers identified that excessive MEK signaling drives T cell exhaustion in cancer immunotherapy. Blocking MEK with FDA-approved inhibitors helped T cells conserve energy and remain active longer in tumor microenvironments, suggesting potential for human trials to enhance immunotherapy effectiveness and prevent treatment fade.
- Excessive MEK activity forces T cells to burn through energy, leading to terminal exhaustion
- Blocking MEK with inhibitors helped T cells conserve energy and survive longer
- FDA-approved MEK inhibitors could potentially be tested in human trials
- Research published in Immunity journal

Genetics¶
7 Discovery of Mobile BC200 Gene in Human Brain Cells¶
Cornell University scientists discovered BC200, a human brain gene evolved from ancient mobile DNA (transposon) that retained the ability to move through the genome—a combination never before observed in a human gene. BC200 is expressed mainly in neurons and appears to regulate protein translation, with potential implications for inheritance through germ cells.
- BC200 evolved from transposon but retained mobility and functional cellular role (rare)
- Expressed mainly in neurons; appears to regulate mRNA-to-protein translation
- Also appears at low levels in germ cells (sperm/eggs), suggesting inheritance potential
- Found embedded in molluscum contagiosum virus (MCV), indicating cross-species jumping
- ~50% of human genome is transposon-derived DNA; most elements no longer active
- Published in Science, September 24, 2026

Space¶
7 NASA Selects GIMLI Project to Explore Lunar Cave Beneath Marius Hill Pit¶
NASA selected the GIMLI (Geophysical Instruments for Marius Lunar pit Investigation) project to investigate whether the Marius Hill Pit on the Moon opens into a vast underground cave or lava tube. Led by Planetary Science Institute's Than Putzig, GIMLI will use ground-penetrating radar, seismic sensors, gravity measurements, and cameras to probe subsurface voids and estimate cave size, funded through NASA's PRISM program with equipment delivered via CLPS commercial landers and rovers.
- Project lead: Than Putzig (Planetary Science Institute)
- Instruments: ground-penetrating radar, seismic sensors, gravity measurements, cameras
- Partners: Honeybee Robotics (equipment), Norwegian Space Agency
- First use of active-source seismic methods on lunar surface since Apollo
- Target: determine if caves/lava tubes exist beneath Marius Hills volcanic region
- Caves could provide radiation shielding and temperature protection for future astronauts
- Funded through PRISM program with delivery via CLPS initiative
