The Trump administration effectively muffled scientific staffers at the Environmental Protection Agency when it rewrote automobile pollution rules, the agency’s watchdog said.

When drafting fuel economy and greenhouse gas pollution rules for cars and light trucks, former EPA Administrator Scott Pruitt decided to cede various EPA duties to the National Highway Transportation Safety Administration in what is typically a collaborative process, the independent inspector general said in a report released yesterday. Though Pruitt signed the final report for the EPA, he allowed NHTSA staff to write a significant portion of the rule and to complete all modeling and analysis for both agencies.

The NHTSA’s modeling efforts did not use the EPA’s established tools that had been created to evaluate greenhouse gas emissions standards. Instead, the NHTSA hacked its own Corporate Average Fuel Economy models and sent EPA experts the results late in the process. “Technical personnel were unable to fully collaborate on rule development,” the report said.

The state of Wisconsin has negotiated a dramatically scaled-back deal with Taiwanese contract manufacturer Foxconn. The move, announced Tuesday by Democratic Gov. Tony Evers, is a repudiation of a deal negotiated four years earlier by Evers' Republican predecessor Scott Walker.

The original deal envisioned Foxconn spending as much as $10 billion to manufacture a state-of-the-art factory for manufacturing large liquid-crystal display panels. The deal was announced in 2017, and then-President Donald Trump traveled to Wisconsin for the 2018 groundbreaking, describing the new factory as "the eighth wonder of the world." Foxconn was supposed to get $2.85 billion in state and local incentives under that original deal.

The deal may have been savvy politics for Foxconn in 2017. The company uses factories in other countries to assemble consumer electronics products for Apple and other American companies—products that are often then sent back to the United States for sale. So Trump's protectionist inclinations seemed like a serious threat. Announcing plans to create of thousands of jobs in a key battleground state gave Trump something to boast about, and that may have helped Foxconn curry favor with the new administration.

For years, Israeli digital forensics firm Cellebrite has helped governments and police around the world break into confiscated mobile phones, mostly by exploiting vulnerabilities that went overlooked by device manufacturers. Now, Moxie Marlinspike—the brainchild behind the Signal messaging app—has turned the tables.

On Wednesday, Marlinspike published a post that reported vulnerabilities in Cellebrite software that allowed him to execute malicious code on the Windows computer used to analyze a device. The researcher and software engineer exploited the vulnerabilities by loading specially formatted files that can be embedded into any app installed on the device.

Virtually no limits

“There are virtually no limits on the code that can be executed,” Marlinspike wrote.

Supernovae happen. We've witnessed enough of them that we're pretty sure of that. Why they happen has been another issue entirely. As we've worked on understanding the physics that drives these immense explosions, we've occasionally gone through awkward periods when the stars in our models stop exploding. Adding in more realistic physics has generally gotten the models booming again, and right now we're in a period where the latest models appear to be happily self-destructing.

The challenge is trying to find evidence that the physics we're using in our successful models accurately reflects what's going on in a dying star—not an easy task with an event that instantly destroys much of the evidence.

Now, data from the Chandra X-ray Observatory provides a hint that a mechanism used in recent supernova models is probably right. The results are published in this week's issue of Nature.
