In 1993, taxol was discovered as a natural product in a newly described endophytic fungus living in the yew tree.  It has since been reported in a number of other endophytic fungi, including Nodulisporium sylviforme ,  Alternaria taxi , Cladosporium cladosporioides MD2 , Metarhizium anisopliae , Aspergillus candidus MD3 , Mucor rouxianus sp. , Chaetomella raphigera , Phyllosticta tabernaemontanae , Phomopsis , Pestalotiopsis pauciseta , Phyllosticta citricarpa , Podocarpus , Fusarium solani , Pestalotiopsis terminaliae , Pestalotiopsis breviseta , Botryodiplodia theobromae Pat. , Gliocladium sp. , Alternaria alternata var. monosporus , Cladosporium cladosporioides , Nigrospora sp. , Pestalotiopsis versicolor , and Taxomyces andreanae . However, there has been contradictory evidence for its production by endophytes, with other studies finding independent production is unlikely.  
A McKinsey report on digitization of the banking industry likely has healthcare implications. New digital competitors like Amazon, Alibaba, and Google are threatening the bottom lines of banks, but those banks that embrace technology and improve their marketing and analytics will reap huge profits through upselling, optimizing their branch formats, enhancing sales productivity through tablet-based digital tools, industrializing operations with automation and artificial intelligence, and adopting APIs to allow working around legacy systems. McKinsey coins the “four horsemen of the e-pocalypse” to describe threats from digital players:
Test 600 has no official certifications. The product itself is not formally backed by any outside research, although its active ingredients do have an amount of proven research behind them. Most of these ingredients are already well known and proven on the market, so there is unlikely to be much change in their certification or research status in the near future. The FDA does not usually put intensive study or certification efforts into herbal extracts. Its safety and effectiveness are primarily a matter of looking at the broader research as discussed above for each ingredient.
