Immunity Ruling

The Supreme Court ruled 6-3 yesterday in finding the president of the United States has some immunity over actions conducted while in office. The case stems from former President Donald Trump's challenge to four felony charges over alleged interference with the 2020 election.


The court’s majority opinion (read here) draws a distinction between official and unofficial acts of the office of the presidency. Trump’s conversations with the attorney general are characterized as official acts, while conversations with others—including then-Vice President Mike Pence—may be categorized as unofficial depending on the context. The court directs lower courts to parse through the allegations to determine which acts may be prosecuted as unofficial acts. 


The ruling was one of four the Supreme Court issued on its last day in session. The court kept a pair of state laws on social media content blocked while lower courts reexamine First Amendment considerations; another ruling extended the statute of limitations for businesses to challenge federal regulations. 


Boeing Buys Back Supplier

Boeing has agreed to acquire longtime fuselage supplier Spirit AeroSystems for $4.7B as part of efforts to improve the aerospace company's plane quality and safety. The deal comes as both companies have been under scrutiny (see timeline) after a midair door panel blowout on an Alaska Airlines flight in January.


The Wichita, Kansas-based Spirit AeroSystems was previously owned by Boeing until a spin-off in 2005. Last year, Boeing accounted for 70% of the supplier's revenue. Under the all-stock deal, Spirit AeroSystems will spin off factories that produce parts for Boeing's European rival, Airbus. The transaction is subject to approval from regulators and Spirit AeroSystems' shareholders. It is expected to close by the middle of next year.  


Separately, the Justice Department is reportedly preparing to present Boeing with a plea deal to avoid trial over fraud conspiracy charges tied to the deaths of 346 people killed in two crashes in 2018 and 2019.  


Bionic Breakthrough

A bionic device developed at MIT allows people to control a leg prosthetic with their minds, according to a new study. The device can yield a more natural gait and reduce phantom limb pain, among other benefits.


The prosthetic takes advantage of muscles’ tendency to move in tandem, with control of one leg muscle signaling a complementary action in the other through the body's nervous system. While traditional surgery severs this muscle connection at the amputation site, a below-the-knee surgery can retain them. A bionic prosthetic can then use electrodes to detect muscle movements, resulting in a more natural gait than traditional robotic legs (more, w/video). In contrast, traditional prosthetics rely on preprogrammed gaits responding to environmental factors like terrain. 


The study has the potential to change the standard of care for hundreds of thousands of Americans who live with the loss of a leg. Researchers hope to make the bionic prosthetic commercially available within five years.
