Quantum Entanglement between Words in our Mind

Researchers have modeled the human mental lexicon as consisting of words that cannot be separated from other words, which may explain why words have many associations, a feature which helps us communicate. The researchers begin by explaining the difference between classical correlations (in the Spreading Activation model) and quantum correlations (in the Spooky Activation at …

Photosynthesis is incredibly efficient

Tracing back along the food web, most of the energy organisms need to survive originates with the Sun. Green plants, cyanobacteria (also known as blue-green algae), and other organisms capture photons and use them to drive the chemical reactions of metabolism. Photosynthesis is incredibly efficient: nearly 100 percent of the energy from the photons absorbed …
