Diese Geschichte beginnt im Labor und endet mit einem aufgeklärten Mordfall... Eines Tages macht der junge Biochemiker Alec Jeffrey bei seiner Arbeit im Labor der Universität Leicester eine weitreichende Entdeckung. Er ist gerade dabei, Blutproben verschiedener Familienmitglieder auf sogenannte Minisatelliten, also hypervariable DNA-Bereiche im menschlichen Genom, zu untersuchen. Da fällt ihm auf, dass diese Minisatelliten präzise jeder Person zugeordnet werden können - der genetische Fingerabdruck ist geboren. Sein Heureka-Moment und der Schlüssel zu einem ungeklärten Mordfall in Leicester. Die Entdeckung des genetischen Fingerabdruckes hat Menschenleben gerettet, trotzdem wirft das auslesen der genetischen Information immer auch ethische Fragen auf... Hier geht's zum Video mit Alec: https://bit.ly/4d0Wazp SO komplex ist unsere DNA wirklich: https://go.nature.com/464w24o Warum das Auslesen des genetischen Fingerabdrucks auch ethische Fragen aufwirft: https://bit.ly/4eSkJjU Margarita Salas Falgueras - DNA-Vermehrung zur Genom-Analyse: https://bit.ly/3LlUPrh Gesetz zum Umgang mit DNA-Proben am Tatort: https://bit.ly/3xUjVKI Willkommen zu unserem True Science-Podcast! Wir reden über die absurden, irren, romantischen und verworrenen Geschichten hinter Entdeckungen und Erfindungen. Denn in der Wissenschaft gibt es jede Menge Gossip! Wir erzählen zum Beispiel, wie die Erfinderin des heutigen Schwangerschaftstests mit Hilfe einer Büroklammerbox den Durchbruch schaffte, oder wie eine Hollywood-Schauspielerin den Grundstein für unser heutiges WLAN legte.

Break the Science Barrier is a TV documentary that I presented on Channel 4 in 1996. It argues for the importance, for society, of scientific ways of thinking. In it, I interviewed David Attenborough, Alec Jeffreys, who discovered DNA fingerprinting, and Douglas Adams, who gave a wonderful impromptu eulogy for science. I also interviewed a man who was wrongly convicted of murder because none of the lawyers, on either side, knew anything about science. The program ends on a more positive note – what I later came to call Science in the Soul.________________________Join Substack:https://richarddawkins.substack.com/Subscribe to Poetry of Reality Channel: https://www.youtube.com/channel/UCmwfdgHA_R9fzr1L0_hxdVwFollow: Instagram: https://www.instagram.com/the.poetry.of.reality/Twitter: https://twitter.com/RichardDawkinsFacebook: https://www.facebook.com/RichardDawkinsBooksReddit: https://www.reddit.com/r/ThePoetryofReality#science #documentary #ThePoetryOfReality #truth #belief #scientific #richarddawkins #darwinism #dawkins #goddelusion #selfishgene

The birth of DNA fingerprinting will forever be tied to Leicester, England. It was invented in a lab in the city's university by Alec Jeffreys in 1984. And it was in the outskirts of the city that it was first used to catch a murderer – Colin Pitchfork who raped and killed the young girls Lynda Mann and Dawn Ashworth.It has gone on to revolutionise policing.Our guest to tell this story is Turi King who was taught by Alec Jeffreys and is now professor of public engagement at Leicester University and the inhouse geneticist on the BBC TV show ‘Family Secrets'.Since this is the final episode in our mini-series on forensics we thought it would be nice to round things out with a chat with a real forensic scientist. Niamh Nic Daeid is the head of Leverhulme Research Centre for Forensic Science in Dundee. We talk about the realities of being a forensic scientist today and what the future might hold.Produced by Freddy ChickEdited by Thomas NtinasExecutive Producer was Charlotte Long Hosted on Acast.

On the morning of Monday September 10th, 1984, Alec Jeffreys, an as yet little-known scientist was looking at a result of an experiment, he'd set running the week previous. He was trying to look at genetic variation between individuals as a way of looking at how diseases might run in families. But what he was about to discover, was a technique that would change the world. Professor Turi King speaks with those involved in the discovery and its first use in a criminal investigation.

The crux of modern forensics is DNA. DNA has been around for a long time. But how did it find its place in solving crimes? It started with two rapes and murders of teenage girls along footpaths in England. Authorities thought they found their man, but a Geneticist named Alec Jeffreys showed them this was not the case. Today's story is the first time mass DNA screening was used, someone was convicted due to DNA evidence, and someone was exonerated due to DNA evidence... all in the same case.

In 1984 British Geneticist and lecturer at the University of Leicester, Alec Jeffreys developed a method to profile DNA whilst studying x-ray images of a DNA experiment. This was first tested publicly in an immigration case the following year -- Jeffreys developed profiles for a young British boy whose family was originally from Ghana, and profiles from the boy’s parents and compared them to prove that the boy was in fact their son.In 1986, Alec Jeffreys’ DNA profiling technique was used for the first time in a criminal case that took place just five and a half miles from the university at which Alec Jeffreys developed the profiling technique.On July 31 1986 15 year old Dawn Ashworth from Enderby, a small town near Leicester in central England, had gone to a friend’s house, her parents expected her home by 9.30 that night, and when she failed to return home they reported her missing to the police. Two days later Dawn’s body was found in a wooded area called Ten Pound Lane.The case was eerily similar to the unsolved case of Lynda Mann, a 15-year-old schoolgirl who had been assaulted and killed in the same savage and brutal manner in November 1983 in the village of Narborough, just a mile away from Enderby. Lynda had been babysitting and had taken a shortcut on her walk home, when she didn’t return home her parents and neighbours went out looking for her. The next morning she was found along a footpath called Black Pad by a local hospital worker.Semen samples were recovered from Lynda’s body and forensic scientists were able to develop a blood type and enzyme profile from the sample, but DNA profiling was still a couple of years away. The enzyme profile and blood sample matched 10% of the population of Britain, which did little to help the police find Lynda’s killer, and so, Lynda’s case went cold. Until 1986 when Dawn was murdered and the two cases were linked. Semen samples recovered from Dawn’s body and clothing matched the blood type and enzyme profile of Lynda’s killer and proved the two girls were killed by the same man. This is the story of how police found their killer.FURTHER READING:Killer BreakthroughColin PitchforkForensic FilesWhere Is Colin Pitchfork Now?

Are we catching up to pop-fiction's futuristic portrayal of DNA in crimesolving? How about a technology that can sketch up an image of a suspect based solely on a sample of his or her DNA? The Fayetteville, North Carolina, Police Department is one of just a few local law enforcement agencies in the U.S. openly using such a tool. Applying it to a decade-old, unsolved local case of a serial rapist, the FPD is catching new tips after releasing facial renderings based on analysis of the perpetrator's DNA -- a potentially important development, as victims didn't get a clear look at his face and could only give authorities limited descriptions. FPD says it's using this innovation cautiously but wants to show the public that the department is willing to try cutting-edge techniques to bring about justice. Hear how it works on this episode.

In 1984, Alec Jeffreys discovered the technique of genetic fingerprinting in a laboratory in the Department of Genetics at the University of Leicester. 30 years later that discover has proven to be not just something for human identification but for identification of any kind. DNA fingerprinting and subsequently DNA profiling has revolutionised the field of forensic science and also the way paternity and immigration disputes are resolved.

Legacy of Leicester: Pivotal Achievements and Discoveries at University of Leicester
In the Department of Genetics, Alec Jeffreys experienced a ‘eureka moment’ when he realised that DNA could be used to identify individuals. The potential for this new technique – subsequently hailed as one of the greatest scientific discoveries of the 20th century – was demonstrated two years later when it was used to solve the murder of two Leicestershire teenagers. DNA fingerprinting is now used by police forces, courts and governments around the world for a host of applications including cases of paternity and immigration
Kirsty Young's castaway this week is Professor Sir Alec Jeffreys - the scientist who discovered genetic fingerprinting. It is 25 years since his 'Eureka moment' - when, pulling an X-ray photograph of his assistant's genetic code out of the developing tray, he realised he could trace the links between her and her parents and that her own unique genetic profile had been revealed. Over the following years, he was the first person to settle immigration disputes, paternity issues and crimes based on DNA identification - he even found himself confirming the identity of the Nazi doctor Josef Mengele, who had fled Germany after the end of the Second World War.As a boy he had always been fascinated by science - he'd made himself a miniature dissection kit so he could find out how a bumble-bee worked and later, spurred on by that success, he remembers bringing a dead cat home and dissecting it on the dining room table. He owes, he says, a debt of gratitude to his parents, who benignly tolerated him turning their family home into a science lab.[Taken from the original programme material for this archive edition of Desert Island Discs]Favourite track: The Opening of Fugue in D Minor by Johann Sebastian Bach Book: Complete books of Flashman by George MacDonald Fraser Luxury: World's Biggest Church Organ.
