Enantioresolution turns bright but racemic gold-silver clusters into circularly polarized emitters

Chiral metal clusters that emit circularly polarized light often face a trade-off between photoluminescence efficiency and luminescence dissymmetry. A study published in the journal Advanced Optical Materials tested whether highly luminescent racemic carbon-centered gold(I)-silver(I) clusters could be converted into bright CPL emitters by enantioresolution with chiral donor ligands.

Hallucination 2/2

In this programme, Geoff Watts meets researchers attempting to unlock the mysteries of hallucination as well as some of those who experience the phenomenon. Geoff visits Dr Dominic Ffytche of the Institute of Psychiatry in London, and undergoes a stroboscopic experiment designed to induce hallucinations in subjects whilst their brains are being scanned. We hear some of the vivid accounts from hallucinators, including Doris, who has macular degeneration. Over the last year, her failing eyesight has resulted in an array of objects and images appearing before her with startling clarity, from relatively benign baskets of flowers to the rather more distressing sight of dark, haunting figures sitting by her bed. Her condition is known as Charles Bonnet Syndrome and Dr Ffytche estimates that over two million people suffer from this in the UK alone, mostly in silence, due to the fear of being labelled as 'mad'. Geoff also visits Kelly Diederen's lab at Cambridge University, which is investigating the origin of auditory hallucinations - hearing voices. Common in people with schizophrenia, Dr Diederen is instead, scanning the brains of so-called "healthy hallucinators," individuals who otherwise lead perfectly functional lives save for the fact that they hear voices on a daily basis. Could they hold the key to understanding and treating a key symptom of psychosis?(Image: Close up of the face of an anonymous male. Credit: BBC)

Hallucination 1/2

Geoff Watts meets researchers attempting to unlock the mysteries of hallucination as well as some of those who experience the phenomenon. Hallucinations aren't what they used to be. Time was when reporting a divine vision would bring fame or fortune. The Enlightenment changed all that and nowadays you'd be more at risk of being handed a prescription for a major tranquilliser for reporting what you saw or heard. Hallucinating, in essence, the experience of seeing or hearing (and sometimes smelling or touching) something that by any objective measure, isn't there, has been linked to a wide variety of causes. But there are also examples of otherwise 'healthy' individuals who have experienced vivid and sometimes distressing hallucinations. With the advent of fMRI scanning, researchers can observe the hallucinating brain in action, it is these 'healthy' individuals who are beginning to open the doors of perception and which may provide new insights and treatments for psychosis and schizophrenia.
