Aanika Biosciences, scientists are working on new technology that can change the process: the tech places invisible, edible microbial tags on each head of lettuce. That makes the tracking process vastly more simple than combing back through records of the produce supply chain on paper, trying to untangle where lettuce came from after it’s been through processing centers that mix greens from multiple farms together. … [Read more...] about These invisible, edible biological tags help track down the cause of E. coli outbreaks

Border Walls Aren’t Just Political Objects—They’re Ecological Barriers, Too
What does this mean for the jaguar? Jaguars, like most large predators, consume a tremendous number of calories every day and therefore require big territories, full of deer and javelinas, in which to hunt. An individual male jaguar may demand up to 53 square miles, and pretty much all the jaguars that have been documented in the United States have been male. The source population is in Sonora, Mexico. The fence will impede all of this: It will limit their territories and intensify competition between individuals. It’ll also make it much more difficult for jaguars to reestablish a breeding population north of the border, effectively reducing our jaguar population to a few escaped zoo animals. To ensure contiguous habitat south of the border, conservationists from Panthera (a group that advocates for wild cats) are at work on the Jaguar Corridor Initiative, which seeks to link the cats’ habitat from Argentina to Mexico. It would be a shame if such a mighty project—and … [Read more...] about Border Walls Aren’t Just Political Objects—They’re Ecological Barriers, Too
Salvage your health resolutions with these 9 simple moves
Create rituals McGraw says we can also create some distance between work life and home by creating rituals. “[For many], there is no physical separation. Work to create mental boundaries, using rituals to start and end your day.” That can start with dressing for work to set the tone for your day. Take a few moments to set up your workstation as you’d prepare your desk in the morning. When you’re finishing your workday, find some small gesture to mark the transition. “Maybe light a candle or go outside for a few minutes to signal the end of the day,” she suggests. The specific action isn’t as important as establishing a habit to help signal to yourself that it’s time to stop work and enjoy some time for yourself. … [Read more...] about Salvage your health resolutions with these 9 simple moves
Hollywood is redefining Peak TV—for better and for worse
Often utilized for historical portraits and dramas, the limited series format has been, well, limited in the number of genres that get the most play. However, one need only to look at British TV to understand how full story arcs can be executed in a handful of episodes across a variety of genres. Take Phoebe Waller-Bridge’s Fleabag or Michaela Coel’s Chewing Gum, both quick-witted comedies featuring a dozen episodes over two seasons—comparable to one season of current American TV. … [Read more...] about Hollywood is redefining Peak TV—for better and for worse
Who wins and loses with the College Board’s cancellation of the SAT essay and subject tests?
What’s actually happening here? The College Board also produces the AP exams. This is the equivalent of an auto company discontinuing a struggling model, and encouraging customers toward its sister model. Subject Test registrations were down 8% from 2016-2019, and plummeted amidst the pandemic. The Board did not note this. … [Read more...] about Who wins and loses with the College Board’s cancellation of the SAT essay and subject tests?
