During fertilization, sperm pass through several physiological environments while still maintaining their shape, using poorly understood mechanisms. Researchers found that male mice lacking cysteine dioxygenase, a protein involved in taurine production, have severely impaired fertility, and that taurine production allows sperm cells to maintain […]

Do we subconsciously judge face-likeness?

Scientists have suggested that face-likeness is judged by early visual processing at around 100ms after viewing an object. The present study focused on the relation between face-likeness recognition and brain activity to suggest for the first time that face-likeness recognition is influenced by early visual processing.
