Professor Jeremy Bailenson has been researching the neurological and psychological impact of virtual reality for 15 years at Stanford's Virtual Human Interaction Lab. Visual, auditory and dynamic spatial cues mimic real-life responses in the brain; he's found that the immersive quality of this technology leaves an indelible mark on users in a way that still images don't.
Food demands on our planet will double by 2050, when the population is set to reach 9.7 billion.
