In the run-up to the 2026 midterm elections, the political parties in many states are working to redefine their congressional district maps to gain every possible edge. From California and Texas to Tennessee and Virginia, redistricting efforts have taken center stage. The Supreme Court has sanctioned partisan gerrymandering, and the system has evolved to one in which state legislature majorities get to determine who is most likely to fill those seats in Congress.
In short, gerrymandering has become a central feature of the system, not a bug. But what if we rethink the structure entirely?
Fake Hermès Birkin bags and other counterfeit luxury goods are popular not only with people on a budget, but also with those with deeper pockets, a new study suggests.
Researchers from the National University of Singapore analyzed millions of counterfeit purchases by American consumers from more than 24,000 U.S. zip codes on a major cross-border, e-commerce platform. They found that both lower- and higher-income individuals are “significantly more likely” to buy fake luxury items than middle-income consumers, according to a press release by INFORMS on Monday.

The COVID-19 pandemic has brought medical supply chains into the spotlight. There has been a national shortage of testing kits, and at least one drug is already unavailable because of the outbreak, though it hasn’t been publicly named.
The COVID-19 crisis may be unfolding on an unprecedented scale, but to U-M engineering associate professor Siqian Shen, its web of logistical puzzles seems eerily familiar. Where to put testing centers, which public facilities to close, and how to allocate ICU beds and design medical triage processes are the kinds of problems that industrial operations researchers like her have been solving for decades. She believes models that are saving businesses money today could be used to save lives tomorrow.
With the Covid-19 virus disrupting the global economy, what is the effect on the international supply chain? In a pair of articles, MIT News examines core supply-chain issues, in terms of affected industries and the timing of unfolding interruptions.
At the Costco in Spokane Valley, Wash., the store is practicing social distancing by limiting how many customers can be in the store at one time.
