The intersection where George Floyd died at the hands of Minneapolis police officers was renamed in his honor, among a series of events to remember a man whose killing forced America to confront racial injustice. Floyd’s brother Terrence was among family members to attend as a commemorative street sign marked the corner of 38th Street and Chicago Avenue as “George Perry Floyd Square” on the two-year anniversary of his death. The renaming was followed by a candlelight vigil at a nearby ceremony. One man who visited the intersection earlier Wednesday, 32-year-old Colten Muth, said he wanted to pay homage to Floyd "because his sacrifice made a huge impact on the world.”

Boeing's astronaut taxi has returned to Earth from the International Space Station, completing a repeat test flight with a mannequin on board. The Starliner capsule parachuted into the New Mexico desert just four hours after leaving the orbiting lab Wednesday. Aside from a few snags, Starliner appears to have clinched its high-stakes shakedown cruise 2 1/2 years after its botched first attempt. That means NASA test pilots will fly next, perhaps by year's end. NASA wants two competing U.S. companies ferrying astronauts to and from the space station. SpaceX is already the established leader.

The U.S. Environmental Protection Agency is proposing restrictions that would block plans for a copper and gold mine in Alaska’s Bristol Bay region. It is the latest in a long-running dispute over efforts by developers to advance the mine in a region known for its salmon runs. Critics of the mine called the EPA's proposal an important step. But the CEO of the Pebble Limited Partnership called it a political maneuver and a preemptive effort to veto the project that Pebble is pursuing. The Pebble partnership is also appealing a 2020 decision from the U.S. Army Corps of Engineers denying approval of a key permit for the project.

In the choppy, cold waters of Alaska’s Resurrection Bay, oceanographers from the University of Alaska Fairbanks have been conducting tests this spring with a drone that goes underwater. They believe it's the first ever configured with a large sensor specifically designed to measure carbon dioxide levels. The underwater autonomous vehicle can dive 1,000 meters in remote parts of the ocean and go on missions for weeks. The intent is to provide a baseline to better understand the ocean’s chemistry and use the enormous amount of data collected to study ocean acidification. Oceans have been absorbing carbon dioxide, but as they take on more, it affects the ability of marine organisms to build and maintain their shells.

Elon Musk on Wednesday revised the financing plan for his proposed $44 billion purchase of Twitter, raising investor hopes that the unpredictable billionaire still intends to pull off a deal roiled by market turbulence and Musk's own unpredictable fixation with the number of fake accounts on Twitter. The changes outlined in a regulatory filing would shave $6.25 billion from the lending package that had been previously lined up for the Twitter buyout. That means Musk will need to secure a total of $33.5 billion in equity commitments, up from $27.25 billion. It's still unclear, though, if the deal will be completed.

The ban, passed by state lawmakers last week, prohibits all abortions with few exceptions.
