As people become more interested in understanding where their food is coming from, blockchain technologies are being eyed as a way to track and record the source of food from the farm to the dining room table, Bloomberg reports.

  • Blockchain is a shared, cryptographically secure ledger of transactions.
  • It's a growing business opportunity in China, where food fraud can be a big problem.
  • Why it matters: Michigan State University"s Food Fraud Initiative says fraud costs the global food industry as much as $40 billion annually. Pew Research Center found that 40 percent of Chinese see food safety is a "very big problem," up from 12% in 2008.

Examples:

  • Wal-Mart is completing a trial using blockchain technologies to track pork in China, cutting the time it takes to track the meat's supply chain from 26 hours to a few seconds, the company tells Bloomberg.
  • Shanghai-based Zhong An Information and Technology Services Co. recently said it will use the technology to track chickens from the coop to the processing facility to the store.
  • Alibaba Group is also working on a blockchain project that will include its food suppliers in Australia and New Zealand.

Congress' next moves to rein in Big Tech

After grilling the CEOs of Amazon, Facebook, Google and Apple last week, members of Congress are grappling with whether to accuse any of the firms of illegal anticompetitive behavior, to propose updating federal antitrust laws — or both.

The big picture: Congress is just one arm of government making the case against these companies. Google is expected to be the first of the firms to face possible antitrust litigation from the Justice Department before summer's end, but all four face a full-court press of investigations by DOJ, the Federal Trade Commission and state attorneys general.

Fauci: Coronavirus task force to examine aerosolized spread

The White House coronavirus task force will examine more closely just how much SARS-CoV-2 might be transmitted via aerosols, and not just from droplets, NIAID director Anthony Fauci said Wednesday at an online forum sponsored by Harvard T.H. Chan School of Public Health.

Why it matters: The longer the coronavirus can remain infectious in the air, the more likely it can infect people, particularly indoors — leading to the possible need to alter air filtration and circulation within buildings.

The next wave to hit Main Street

Call it the great retail wash. A wave of defaults, bankruptcies and evictions expected in cities across the U.S. is poised to remake the retail landscape across the country, but there may be some upside for consumers and small businesses.

Why it matters: Rather than an overnight descent into a collection of urban wastelands full of Starbucks, Amazon fulfillment centers, Chase bank branches and nothing else, the coronavirus pandemic and resulting retail apocalypse may just mean that, in major U.S. cities, less is more.
