Could audio files be the new digital drugs? New research shows that binaural beats - illusionary tones created by the brain when the brain hears two different tones in each ear – can change someone’s emotional state. The work, published in Drug and Alcohol Review, shows for the first time that people use binaural beats to relax, fall asleep and even to try to get a psychedelic drug high. BBC’s R&D Audio team have created a binaural beat soundscape especially for Digital Planet and we speak to Dr Alexia Maddox, a tech sociologist, one of the researchers behind the study.Publishing via What’s App – getting female authors recognised in Zimbabwe Getting a book deal may seem like an impossible dream for many budding authors, but in Zimbabwe, for many female writers, this is a reality.
