It's difficult to comprehend what 1,000 cubic kilometers of rock would look like. It's even more difficult to imagine it being violently flung into the air. Yet the Yellowstone volcanic system blasted more than twice that amount of rock into the sky about 2 million years ago, and it has generated a number of massive (if somewhat smaller) eruptions since, and there have been even larger eruptions deeper in the past .

All of which might be enough to keep someone nervously watching the seismometers scattered throughout the area. But a new study suggests that there's nothing to worry about in the near future: There's not enough molten material pooled in one place to trigger the sort of violent eruptions that have caused massive disruptions in the past. The study also suggests that the primary focus of activity may be shifting outside of the caldera formed by past eruptions.

Understanding Yellowstone

Yellowstone is fueled by what's known as a hotspot, where molten material from the Earth's mantle percolates up through the crust. The rock that comes up through the crust is typically basaltic (a definition based on the ratio of elements in its composition) and can erupt directly. This tends to produce relatively gentle eruptions where lava flows across a broad area, generally like you see in Hawaii and Iceland. But this hot material can also melt rock within the crust, producing a material called rhyolite. This is a much more viscous material that does not flow very readily and, instead, can cause explosive eruptions.

The US government finally got its metaphorical hands on Do Hyeong Kwon, the 33-year-old Korean national who built a financial empire on the cryptocurrency Luna and the "stablecoin" TerraUSD, only to see it all come crashing down in a wipeout that cost investors $40 billion.

As private investors filed lawsuits, and as the governments of South Korea and the United States launched fraud investigations, Do Kwon was nowhere to be found. In 2022, the Korean government filed a "red notice" with Interpol , seeking Kwon's arrest and his return to Korea. A few months later, the Securities and Exchange Commission charged Kwon with fraud in the US.

On September 17, 2022, Kwon famously tweeted , "I am not 'on the run' or anything similar"—but he also wouldn't say where he was. He didn't help his case when he was arrested in March 2023 by the authorities in Montenegro. At an airport. With fake travel documents. On his way to a country with no US extradition agreement.

Last September, faulty door handle hardware caused Volkswagen to take the rather drastic steps of suspending sales and production of the electric crossover, as well as recalling almost 100,000 customer cars. Now, it says it has new parts that will allow it to fix existing cars, lift the stop-sale order, and soon, resume production at its factory in Chattanooga, Tennessee.

The ID.4, like many new EVs, features flush door handles in service of the all-important effort of drag reduction. Instead of conventional mechanical handles that interrupt the laminar air flow down the side of the car, VW instead went with an electromechanical solution.

Unfortunately, the door handle assemblies weren't sufficiently waterproofed, allowing the electronics inside to corrode. Consequently, early last year VW started getting complaints of ID.4s with doors that would intermittently open while driving, with reporting almost 300 warranty claims by September, when it pulled the car from sale, issued the recall, and stopped the production line.
