Robin Alderman faces an agonizing reality: Gene therapy might cure her son Camden’s rare, inherited immune deficiency. But it’s not available to him. ... Collectively, about 350 million people worldwide suffer from rare diseases, most of which are genetic. But each of the 7,000 individual disorders affects perhaps a few in a million people or less. There’s little commercial incentive to develop or bring to market these one-time therapies to fix faulty genes or replace them with healthy ones. (Ungar, 6/21)

Inside every human is a thriving zoo of bacteria, fungi, viruses and other microscopic organisms collectively known as the microbiome. Trillions of microbes live in the digestive tract alone, a menagerie estimated to contain more than 1,000 species. This ecosystem of tiny stuff affects our health in ways science is only beginning to understand, facilitating digestion, metabolism, the immune response and more. But when serious infection sets in, the most powerful antibiotics take a merciless approach, wiping out colonies of beneficial bacteria in the digestive tract and often prompting secondary health problems.
