The ATLAS Collaboration at CERN's Large Hadron Collider has observed the coincident production of a single top quark and a photon in proton-proton collisions. This observation provides valuable insights into the electroweak interaction of the top quark, the heaviest known fundamental particle.

Further analysis and data collection will help uncover the properties of these events and their implications for physics beyond the standard model.
Scientists have discovered that a single photon of light can initiate the process of photosynthesis in plants, algae, and bacteria. In a new experiment, researchers used a light source that produced two photons, with one photon being absorbed by light-harvesting structures in a bacterium. Instead of passing the energy to other molecules as in normal photosynthesis, the absorbed photon emitted a third photon with a different wavelength, indicating the transfer of energy. This finding suggests that a single photon can kick off photosynthesis, shedding light on the early reactions of this vital process.
Scientists have observed the beginning of photosynthesis for the first time, starting with a single photon. Researchers looked at purple photosynthetic bacteria and set up a photon source that spits out just two photons at a time. During each test, the first photon fired out was absorbed by an ultra-sensitive detector, while the other struck the bacteria's equivalent of a chloroplast. When the second photon hit its target, photosynthesis started up, confirming that just one photon was enough to set off photosynthesis.
