Almanac The Body Learns Who It Is
  • Why had organ transplants been failing for decades even when surgeons could perform the operation flawlessly?
  • How did Burnet and Medawar's discovery eventually lead to preventing rejection in transplanted organs?

  • What groundwork had Norman Shumway's dog studies laid before Christiaan Barnard performed the first human transplant?
  • Why was the legal status of brain death an unresolved question at the time of the operation?

Almanac Mouse Grafts and the Meaning of Self
  • How did Baruj Benacerraf's work on MHC genes explain why organ transplants fail?

Almanac Tethered to a Refrigerator-Sized Heart
  • What was the Jarvik-7, and what materials was it made from?
  • Why was Barney Clark's implant considered a permanent replacement rather than a bridge to a donor heart?
  • What complications did Barney Clark experience while living with the artificial heart, and how long did he survive?

Almanac Borrowed Marrow, Lasting Life
  • Why did Joseph Murray's 1954 kidney transplant between identical twins succeed where transplants between unrelated people failed?
  • What immunosuppression protocols did E. Donnall Thomas develop to make bone marrow transplants work between unrelated people?

Almanac Verdi Outperforms Silence in Mouse Hearts
  • What did researchers find when they played opera to transplanted mouse hearts compared to silence?
  • How did Verdi's La Traviata compare to Mozart and to monotonous tones in prolonging survival?
Almanac Fourteen Edits, One Working Kidney
  • Why are pig kidneys an anatomically promising option for addressing the shortage of transplantable human kidneys?
