Dr. Devi Shetty, a cardiac surgeon, has been on a mission to provide even the poorest of the poor with quality, affordable healthcare.

At Narayana Health, a chain of hospitals in India, surgeons perform the most complicated procedures at a tiny fraction of what it costs in the US. Its ability to do so partly lies in the use of well-known operations principles to promote process efficiency.

In Chile, Labs Sniff Out Quality Control Issues

In Chile, Labs Sniff Out Quality Control Issues

March 12, 2019

Five Labradors Retrievers are the newest quality control experts at Chilean barrel maker, TN Coopers.

Trained in a manner similar to K-9 dogs used by police forces, these Labs can sniff very small amounts of chemical compounds which cause “cork taint” and lead to unappealing aromas and flavors in wine. This problem can occur on the cork, as the name suggests, but it can also happen when the barrels are contaminated earlier in the production process.

The dogs constantly patrol the cooperage, looking for any contaminants before products are shipped out. TN Coopers also rents the dogs to wineries for use in detecting quality problems, and more puppies may be bred and trained for use in California wineries in the future.
