“Human waste, empty oxygen cylinders, kitchen leftovers and discarded ladders.

Sherpas working on Mount Everest carry all that and more — 20 kilograms (44 pounds) per person — navigating a four-hour hike that traverses crumbling glacial ice and treacherous crevasses to bring trash back to base camp.

During the most recent climbing season, they had new assistance from two giant SZ DJI Technology Co. drones, which can complete the same journey in six minutes, sharing the task of clearing an expanding volume of refuse piling up on the world’s highest peak…

‘We’re very happy,’ said Lhakpa Nuru Sherpa, a 33-year-old Sherpa at local expeditions firm Asian Trekking who has reached the summit of Everest 15 times. He estimates that about 70% of the garbage usually carted off the mountain by his team was transported by drone this year.”

“In 2010, there were just 13 million mobile money accounts in the world, fewer than the population of my home country, the Netherlands. By 2023, this had reached more than 640 million. That’s more than twice the total number of Netflix subscriptions worldwide…

What’s immediately obvious is how much of this growth has come from Sub-Saharan Africa; it’s home to more than half of the world’s accounts. In 2023, there were over 330 million active mobile money accounts in the region; more than one mobile money account for every four people.

What’s changed? One of the obvious drivers of this growth has been the widespread adoption of mobile phones, not just in the richest countries but across the globe. Mobile subscriptions have surged in nearly every region.

But the total number of mobile money accounts doesn’t tell us what percentage of people use mobile money. A small portion of people could each have many accounts. So instead of examining absolute numbers, let’s look at the share of people with mobile money accounts in Sub-Saharan Africa.

As the chart below illustrates, the percentage of people in Sub-Saharan Africa with a mobile money account grew rapidly, from 12% in 2014 to 33% by 2021.”

“The American Federation of Teachers, the second-largest U.S. teachers’ union, said on Tuesday that it would start an A.I. training hub for educators with $23 million in funding from three leading chatbot makers: Microsoft, OpenAI and Anthropic.

The union said it planned to open the National Academy for A.I. Instruction in New York City, starting with hands-on workshops for teachers this fall on how to use A.I. tools for tasks like generating lesson plans.

Randi Weingarten, president of the American Federation of Teachers, said the A.I. academy was inspired by other unions, like the United Brotherhood of Carpenters, that have worked with industry partners to set up high-tech training centers.”

“Teeth from an elderly man who lived around the time that the earliest pyramids were built have yielded the first full human genome sequence from ancient Egypt.

The remains are 4,800 to 4,500 years old, overlapping with a period in Egyptian history known as the Old Kingdom or the Age of Pyramids. They harbour signs of ancestry similar to that of other ancient North Africans, as well as of people from the Middle East, researchers report today in Nature.”
