2026 Nobel Prize in Physiology or Medicine goes to Deisseroth, Hegemann and Nagel for optogenetics
- On 5 October 2026, the Nobel Prize in Physiology or Medicine was awarded to Karl Deisseroth, Peter Hegemann and Georg Nagel.
- It honours their discoveries on light-gated ion channels and optogenetics.
- Hegemann and Nagel found channelrhodopsin, a light-sensitive protein, in the single-celled alga Chlamydomonas.
Why it matters
[Milestone] Optogenetics lets scientists turn chosen nerve cells on or off with light. Older methods could map brain areas but could not prove cause and effect. Now researchers can link specific circuits to memories, feelings and behaviour. Doctors are testing the method to restore sight in people with visual impairment. Nobel prizes are a regular GK question in SSC, CDS and NDA papers.
National Supercomputing Mission reaches 40 supercomputers with 68 petaflops of capacity
- As of September 2026, 40 supercomputers had been deployed under the National Supercomputing Mission (NSM).
- Their combined capacity is 68 petaflops. Thirteen of them are high-end systems above 1 petaflop.
- The Mission plans 50 supercomputers with more than 123 petaflops in total.
Why it matters
[Data] NSM was launched in April 2015 with an outlay of about ₹4,500 crore. It is steered jointly by the Department of Science and Technology (DST) and MeitY. C-DAC Pune and IISc Bengaluru implement it. India's journey began with C-DAC's PARAM 8000 in 1991. The Rudra servers show the shift from assembling imports to building indigenous hardware. This is GS-3 science and technology and Aatmanirbhar Bharat material.
India’s first 5.56 km free-space quantum key distribution link demonstrated in Gandhinagar
- QNu Labs, BISAG-N and IIT Gandhinagar demonstrated India's first free-space QKD link at a 5.56 km scale.
- The field trial ran on the night of 27-28 September 2026, between BISAG-N and IIT Gandhinagar.
- It kept the quantum bit error rate below 5% and generated secure keys at 230-260 bits per second.
Why it matters
[First] Quantum Key Distribution (QKD) shares encryption keys using single particles of light. Any attempt to eavesdrop disturbs them and shows up as errors. Free-space QKD needs no optical fibre, so it can work through open air. The team says this paves the way for longer links and satellite-based quantum communication.
Asian Games 2026: India wins 85 medals; both hockey teams take gold and qualify for LA 2028
