Melvyn Bragg and his guests discuss the Neanderthals.In 1856, quarry workers in Germany found bones in a cave which seemed to belong to a bear or other large mammal. They were later identified as being from a previously unknown species of hominid similar to a human. The specimen was named Homo neanderthalis after the valley in which the bones were found.This was the first identified remains of a Neanderthal, a species which inhabited parts of Europe and Central Asia from around 400,000 years ago. Often depicted as little more advanced than apes, Neanderthals were in fact sophisticated, highly-evolved hunters capable of making tools and even jewellery.Scholarship has established much about how and where the Neanderthals lived - but the reasons for their disappearance from the planet around 28,000 years ago remain unclear.With: Simon Conway MorrisProfessor of Evolutionary Palaeobiology at the University of CambridgeChris Stringer Research Leader in Human Origins at the Natural History Museum and Visiting Professor at Royal Holloway, University of LondonDanielle SchreveReader in Physical Geography at Royal Holloway, University of LondonProducer: Thomas Morris.

Folge vom 20.05.2010The Cavendish Family in ScienceFrom the 1600s to the 1800s, scientific research in Britain was not yet a professional, publicly-funded career.So the wealth, status and freedom enjoyed by British aristocrats gave them the opportunity to play an important role in pushing science forwards - whether as patrons or practitioners.The Cavendish family produced a whole succession of such figures.In the 1600s, the mathematician Sir Charles Cavendish and his brother William collected telescopes and mathematical treatises, and promoted dialogue between British and Continental thinkers. They brought Margaret Cavendish, William's second wife, into their discussions and researches, and she went on to become a visionary, if eccentric, science writer, unafraid to take on towering figures of the day like Robert Hooke.In the 1700s, the brothers' cousin's great-grandson, Lord Charles Cavendish, emerged as a leading light of the Royal Society.Underpinned by his rich inheritance, Charles' son Henry became one of the great experimental scientists of the English Enlightenment.And in the 1800s, William Cavendish, Henry's cousin's grandson, personally funded the establishment of Cambridge University's Cavendish Laboratory. In subsequent decades, the Lab become the site of more great breakthroughs.With:Jim BennettDirector of the Museum of the History of Science at the University of OxfordPatricia FaraSenior Tutor of Clare College, University of CambridgeSimon SchafferProfessor of History of Science at the University of Cambridge and Fellow of Darwin College, CambridgeProducer - Phil Tinline.

Folge vom 06.05.2010The Cool UniverseThe Cool Universe is the name astronomers give to the matter between the stars.These great clouds of dust and gas are not hot enough to be detected by optical telescopes.But over the last few decades, they have increasingly become the focus of infrared telescopy.Astronomers had long encountered dark, apparently starless patches in the night sky. When they discovered that these were actually areas obscured by dust, they found a way to see through these vexing barriers, using infrared telescopes, to the light beyond.However, more recently, the dust itself has become a source of fascination.The picture now being revealed by infrared astronomy is of a universe that is dynamic.In this dynamic universe, matter is recycled - and so the dust and gas of the Cool Universe play a vital role. They are the material from which the stars are created, and into which they finally disintegrate, enriching the reservoir of cool matter from which new stars will eventually be formed. As a result of the new research, we are now beginning to see first-hand the way our planet was formed when the solar system was born.With:Carolin CrawfordMember of the Institute of Astronomy, and Fellow of Emmanuel College, at the University of CambridgePaul MurdinVisiting Professor of Astronomy at Liverpool John Moores University's Astronomy Research InstituteMichael Rowan-RobinsonProfessor of Astrophysics at Imperial College, LondonProducer: Phil Tinline.

Folge vom 04.03.2010The Infant BrainMelvyn Bragg and guests Usha Goswami, Annette Karmiloff-Smith and Denis Mareschal discuss what new research reveals about the infant brain.For obvious reasons, what happens in the minds of very young, pre-verbal children is elusive. But over the last century, the psychology of early childhood has become a major subject of study. Some scientists and researchers have argued that children develop skills only gradually, others that many of our mental attributes are innate. Sigmund Freud concluded that infants didn't differentiate themselves from their environment. The pioneering Swiss child psychologist Jean Piaget thought babies' perception of the world began as a 'blooming, buzzing confusion' of colour, light and sound, before they developed a more sophisticated worldview, first through the senses and later through symbol. More recent scholars such as the leading American theoretical linguist Noam Chomsky have argued that the fundamentals of language are there from birth. Chomsky has famously argued that all humans have an innate, universally applicable grammar.Over the last ten to twenty years, new research has shed fresh light on important aspects of the infant brain which have long been shrouded in mystery or mired in dispute, from the way we start to learn to speak to the earliest understanding that other people have their own minds.
