The Download: amazing space, and geoengineering restrictions

How the James Webb Space Telescope broke the universe

When the James Webb Space Telescope sent its first images back to Earth in July last year, researchers gathered excitedly to pore over them. JWST, a NASA-led collaboration between the US, Canada, and Europe, is the most powerful space telescope in history and can view objects 100 times fainter than the Hubble Space Telescope. Those images contained the first clear evidence for carbon dioxide in the atmosphere of a planet outside the solar system.

Almost immediately after it started full operations, incredible vistas from across the universe poured down, from images of remote galaxies at the dawn of time to amazing landscapes of nebulae, the dust-filled birthplaces of stars.

Months later, JWST continues to send down reams of data to astonished astronomers on Earth, and it is expected to transform our understanding of the distant universe, exoplanets, planet formation, galactic structure, and much more. Read the full story.

What Mexico’s planned geoengineering restrictions mean for the future of the field

What’s happened: Last month, a US startup called Make Sunsets claimed it had conducted a solar geoengineering experiment in Baja California, Mexico, launching a pair of weather balloons laden with a few grams of sulfur dioxide into the stratosphere. Now, the Mexican government plans to ban related experiments.

Why it matters: Scientists believe that spraying sulfur dioxide or other reflective particles into the stratosphere in sufficient quantities might be able to offset some level of global warming. But the unknown side effects, coupled with the difficult questions over how to govern a temperature-tweaking technology, make it highly controversial.

What’s next: The startup didn’t seek approval before its balloon launch. Now, by announcing plans to prohibit any future solar geoengineering experiments, Mexico may be one of the first nations, if not the first, to announce an explicit ban on such projects. Read the full story.

Quote of the day

“I’ve never heard of a customer that says, ‘I’m going to wait until the economic environment improves to deal with a rat that’s running round my kitchen.’”

—Andy Ransom, CEO of pest control company Rentokil, which has started using facial recognition technology to monitor rats, tells the Financial Times why he’s confident the business can cope in an economic downturn.

The big story

Tech’s new labor movement is harnessing lessons learned a century ago

June 2021

Back in 2020, as the world struggled to cope with the pandemic, workers at the Amazon fulfillment center in Bessemer, Alabama, were being pressed to work harder and longer. They felt dehumanized, and wanted dignity, not just higher wages.

Workers pushed to join the Retail, Wholesale, and Department Store Union, but Amazon waged war on the campaign, and eventually a vote passed in favor of keeping the status quo. Elsewhere, however, other workers across the country had started agitating. 

The Bessemer fight, and Amazon organizing as a whole, reflect a new groundswell of interest in organizing among tech workers. Today’s workers are up against the world’s richest companies. But for both sides in this struggle, the bottom line is not money but power. Read the full story.
