On the Hopi Reservation’s more than 1.5 million acres of desert landscape in northeast Arizona, most residents live in villages atop arid mesas.

Air traffic controllers need help. We don’t yet know what caused the recent Japan Haneda airport runway collision earlier this month, but there is evidence, both abroad and in the U.S., that air traffic control is stretched too thin. And that could have disastrous consequences on planes’ and passengers’ safety.
Last month, the New York Times reported that air traffic controllers have become “an exhausted and demoralized workforce that is increasingly pron

An Atlas Air Boeing 747-8 cargo plane with five crew members made an emergency landing at Miami International Airport (MIA) late Thursday after facing an engine malfunction shortly after departure.
Unverified videos on social media platform X showed flames shooting out of the left wing of the aircraft while in flight. No injuries were reported, the airport told Reuters.
“The crew followed all standard procedures and safely returned to MIA,” the air-

Retirement plans like 401(k)s are considered some of the most sought-after workplace benefits in the U.S., and they’re even required of many employers in jurisdictions like California.
But for employers and employees alike, setting up plans and contributions has often been painful and confusing, says Kevin Busque, founder and CEO of retirement plan provider Guideline.
Busque, who previously cofounded Taskrabbit, says he became interested in the 401(k) industry after

The European Union’s competition watchdog appears set to thwart Amazon’s $1.4 billion acquisition of the robot vacuum maker iRobot, according to sources connected to the Wall Street Journal. This has triggered a sharp decline of almost 40% in the stock shares of the Roomba vacuum manufacturer, which plunged in after-hours trading following the report.

Apple has promised to open up its tap-and-go mobile payment system to rivals, the European Union said Friday, as the U.S. tech company seeks to resolve an antitrust case and avoid a fine that potentially could be worth billions.
Apple proposed letting third-party mobile wallet and payment service providers access the contactless payment function on its iOS operating system, the EU said. The 27-nation bloc now is seeking feedback from “all interested parties”

Sheryl Sandberg’s announcement that she would not stand for reelection to the Meta board in May was, in many ways, the last step in her long exit from the company. While she’ll stay on as an adviser and said she will “always be there to help the Meta teams,” the days of her outsize level of influence at the company are seemingly at an end.
Founder and CEO Mark Zuckerberg, of course, is the person whose opinion matters most at Meta. He controls more than 5

Surgeons externally attached a pig liver to a brain-dead human body and watched it successfully filter blood, a step toward eventually trying the technique in patients with liver failure.
The University of Pennsylvania announced the novel experiment Thursday, a different spin on animal-to-human organ transplants. In this case, the pig liver was used outside the donated body, not inside—as a way to create a “bridge” to support failing livers by doing the organ&#x

Wastewater testing does a good job at detecting mpox infections, U.S. health officials said in a report Thursday that bolsters a push to use sewage to track more diseases.
U.S. Centers for Disease Control and Prevention (CDC) researchers found that over the course of a week, there was a 32% likelihood the tests would detect the presence of at least one person infected with mpox in a population ranging from thousands to millions.
Amy Kirby, who oversees the CDC’s was
