Japanese Encephalitis vectors; climate change and effect on health; archival heart transplant; and data behind decreased heart attacks

Japanese Encephalitis (JEV) is common in Asia but now causing concern in Australia. The rise of JEV in Australia happened when the Intergovernmental Panel on Climate Change (the IPCC) were reporting on climate change—a key aspect of which was the effect of climate on health. There's unique archival audio from the 1980s of the surgeon who performed a heart transplant operation on Baby Fae - using a baboon heart. And the records of 80 million people have been assessed to see why there are now less deaths from heart attack.
