NGC 1266, a galaxy after the burst
Hubble’s view of NGC 1266 shows a rare post-starburst lenticular galaxy about 100 million light-years away in Eridanus. Astronomers think a minor merger roughly 500 million years ago helped trigger a burst of star formation and feed the central black hole; the galaxy is now running quieter, with dusty filaments and a bright core left as evidence of the transition.

1749
Edward Jenner is born
On 17 May 1749, Edward Jenner was born in Berkeley, Gloucestershire. His later smallpox vaccination experiments did not invent immunity, but they helped turn an old rural observation about cowpox into a public-health technology. Two and a quarter centuries later, that line runs through immunology, clinical trials, vaccine logistics and the eradication of smallpox itself.

Quantum and classical processing with photonic quantum machine learning
S. D. Bartlett et al.
A programmable silicon-photonics chip is used as a quantum reservoir computer, taking single-photon inputs and producing measurements that can support both quantum tasks and classical machine-learning benchmarks. Treat it as a lab-scale hardware result rather than proof of near-term advantage over GPUs: the value is in showing a reconfigurable photonic platform where machine learning happens partly as physics in a chip, with explicit caveats around scale, noise and experimental imperfections.
