Radio Replay: Loving the Lie

In this week's Radio Replay, we bring you stories of fakes, phonies, and con men — and the people who fall for the false worlds they create. First, the tale of a middle-aged man who impersonates a series of women and gets thousands of men to fall in love with his creations. Then, we'll hear about a painter who tricks the world's greatest art experts into believing they're looking at masterpieces. Hosted by Simplecast, an AdsWizz company.

Plate Tectonics and Life

Earthquakes are feared for their destructive, deadly force. But they are part of a geological process - plate tectonics - that some scientists say is vital for the existence of life itself. Without the ever-changing land surfaces that plate tectonics produces, or the high continental masses raised above sea level by earthquake activity, planet Earth would atrophy into a lifeless mass, like our neighbour Mars. But why is Earth the only planet with plate tectonics? And, when did they start? The clues are so faint, the traces so ephemeral, that researchers are only now beginning to find tentative answers. Extraordinarily, some say that life itself has changed the forces in plate tectonics, and helped to shape the world.

Quorum Sensing

A radically different approach to dealing with bacteria would be to stop them from communicating and coordinating attacks, rather than trying to kill them. The bugs would be rendered harmless and much less likely to develop drug resistance. This is the hope of researchers who are working on an aspect of bacterial life known as Quorum Sensing.Medical experts have warned that within 20 years, unless something is done, the spread of antibiotic resistance may have returned us to an almost 19th Century state of medicine. Infections following routine operations will be untreatable and fatal because so many common bacteria will have acquired immunity to all the available antibiotic drugs.The vast majority of the antibiotics we rely upon today were developed between the 1940s and 1970s. There has been no new class of antibiotic for 25 years.Bacteria may just be single-celled organisms but microbiologists now realise they have a kind of social life. They need to cooperate and coordinate their attacks on the bodies they infect. Many kinds of bacteria only become dangerous to us when they sense that their numbers are high enough. Only when they 'know' that there are enough of them to overwhelm human defences, do they release their toxins and cause illness and death.Geoff Watts talks to scientist and doctors who are exploring this phenomenon in disease-causing bacteria. They are trying to devise ways of interfering with microbial communications. One line of thinking is the development of drugs which stop the microbes from either 'talking' or 'hearing' the chemical messages. Another more radical idea, is to treat infected patients with doses of the kind of bacteria causing the illness - except that the 'medicinal' bugs would be ones that would subvert the communication system and br

Build Me a Brain

When President Obama recently complained, that although "we can identify galaxies light years away, study particles smaller than an atom ... we still haven't unlocked the mystery of the three pounds of matter that sits between our ears" - he called on scientists to unravel the trillions of neural connections inside our brains that make our minds work.Some researchers are already doing that - trying to understand the brain by starting to build one. At Reading University, at the newly constructed Brain Embodiment Laboratory, researchers plan to connect cultures of living human neurons to robots - to give meaning to their neural activity. At Georgia Tech, Atlanta, neuroengineer Steve Potter, agrees that cultured neurons not connected to the outside world suffer sensory deprivation. His neural arrays descend into spasms of epileptic activity when left alone. When plugged in, they can control machines across the planet."I believe these cultures are half-way to having a mind," says Potter. "Wired up to listen to their own outputs, they could be self aware."Other researchers are building brains from inanimate materials - using tendrils of silver, silicon and sulphur that spring into life like activity when wired up to electricity. At Stanford University, plans are afoot to meld them with living neurons - perhaps to enhance our thought processes.These devices can learn, remember and process information - but do they think? Can these scientists really build a brain? And what would it tell us about ours if they could?
