The First Kidney Transplant Used Identical Twins to Cheat Rejection
DID YOU KNOW? The First Kidney Transplant Used Identical Twins to Cheat Rejection On 23 December 1954, Dr Joseph Murray transplanted a kidney between identical twins Richard and Ronald Herrick. It was the first successful organ transplant in history. The Short Answer: By using identical twins — whose immune systems are genetically indistinguishable — Murray bypassed the rejection problem that had defeated every previous transplant attempt. Richard Herrick survived eight years with his brother's kidney. The operation proved organ transplantation was possible. Every previous attempt at organ transplantation had failed... Read more...
The First Surgery Under Ether Anaesthesia Was Called a Yankee Dodge
DID YOU KNOW? The First Surgery Under Ether Anaesthesia Was Called a Yankee Dodge On 16 October 1846, dentist William Morton demonstrated ether anaesthesia at Massachusetts General Hospital. It was the moment surgery stopped being torture. The Short Answer: Crawford Long first used ether for surgery in 1842 in rural Georgia, but never published his findings. William Morton's public demonstration at Massachusetts General Hospital in 1846 — known as Ether Day — is the event that changed surgery worldwide. The patient felt no pain, and the watching surgeons were stunned.... Read more...
X-Rays Were Discovered Completely by Accident
DID YOU KNOW? X-Rays Were Discovered Completely by Accident Wilhelm Conrad Röntgen was experimenting with cathode rays in 1895 when he noticed a mysterious glow on a nearby screen. He had just discovered X-rays — and won the first ever Nobel Prize in Physics. The Short Answer: On 8 November 1895, Röntgen noticed that a barium platinocyanide screen across his laboratory was glowing even though it was shielded from the cathode ray tube. Something invisible was passing through solid objects. He called it X-radiation — X for unknown. The discovery... Read more...
The CT Scanner Was Funded by Beatles Record Sales
DID YOU KNOW? The CT Scanner Was Funded by Beatles Record Sales The technology that revolutionised medical imaging was developed at EMI — the same company that signed The Beatles. Record profits helped fund the research. The Short Answer: Godfrey Hounsfield, an engineer at EMI (Electrical and Musical Industries), invented the CT scanner in the early 1970s. EMI's enormous profits from Beatles record sales gave the company the financial freedom to fund his research, which won the Nobel Prize in 1979. It is one of the most unlikely connections in...

DID YOU KNOW? The First IVF Baby Was Born in Oldham in 1978 Louise Brown, the world's first baby conceived through in vitro fertilisation, was born on 25 July 1978 at Oldham General Hospital. Over 12 million IVF babies have been born since. The Short Answer: Louise Joy Brown was born weighing 5lb 12oz by planned Caesarean section. Her birth was the result of years of research by Dr Patrick Steptoe and Professor Robert Edwards, and it gave hope to millions of couples struggling with infertility worldwide. Before Louise Brown,... Read more...
Your Entire Skeleton Replaces Itself Every 10 Years
DID YOU KNOW? Your Entire Skeleton Replaces Itself Every 10 Years Your bones are not the permanent scaffolding they appear to be. They are living tissue, constantly breaking down and rebuilding in a process that replaces your entire skeleton roughly once a decade. The Short Answer: Through a process called bone remodelling, osteoclasts break down old bone while osteoblasts build new bone. This continuous cycle means your skeleton is completely replaced approximately every 7 to 10 years. We tend to think of bones as fixed and unchanging, like the girders... Read more...
The First Heart Transplant Patient Survived Just 18 Days
DID YOU KNOW? The First Heart Transplant Patient Survived Just 18 Days On 3 December 1967, Christiaan Barnard performed the world's first human-to-human heart transplant in Cape Town. The operation changed surgery forever. The Short Answer: Dr Christiaan Barnard transplanted the heart of Denise Darvall into Louis Washkansky at Groote Schuur Hospital in Cape Town, South Africa. Washkansky survived 18 days before dying of pneumonia, but the operation proved that heart transplantation was surgically possible. Before 3 December 1967, replacing a human heart was considered impossible by most of the... Read more...
Your Liver Can Regenerate From Just 25% of Its Original Size
DID YOU KNOW? Your Liver Can Regenerate From Just 25% of Its Original Size The liver is the only internal organ in the human body that can regrow itself after surgical removal. Surgeons have relied on this ability for decades. The Short Answer: The human liver can regenerate to its full size from as little as 25% of its original tissue. This extraordinary ability makes living-donor liver transplants possible and has shaped surgical practice for over half a century. No other solid organ in the human body can do what... Read more...
