Physicists say they can explain how a photon with an energy of 300 teraelectronvolts — among the most energetic gamma rays ever detected — managed to arrive at Earth. Such extreme photons are expected to be absorbed or degraded over cosmic distances, so the finding is drawing attention as a challenge to standard models of high-energy astrophysics and may point to unexpected sources or propagation mechanisms.

Scientists report measuring a photon that, according to standard understanding, should never have reached Earth. The detection challenges current models of how high-energy particles travel across the universe, and physicists are weighing whether it points to new physics or an error in existing assumptions. Discussion is spreading across the science community as experts debate possible explanations for the impossible detection.

Researchers have developed stacked nanomembranes that combine electro-optic and magneto-optic capabilities on micro-ring structures, according to a report by AZoNano.

A report claims that a single photon may be conscious, an idea at the fringe of physics and philosophy of mind. If taken seriously, it would extend theories like panpsychism deep into quantum mechanics and challenge standard views of consciousness as a product of complex brains. Scientists have reacted with scepticism, noting there is no experimental evidence that individual photons have subjective experience, and the claim remains speculative.

Researchers have invented a modular materials framework aimed at enabling advanced photonic circuits, which use light rather than electrical signals to process information.
