The Download: China’s digital red packet jamboree, and a methane-leak mapping satellite

How the internet pushed China's New Year red packet tradition to the extreme

If you ask any child in China what's the most exciting thing about the Lunar New Year, they are likely to answer: the red packets. It's a festive tradition: During the holidays, people give out red envelopes of cash to young members of the family. You can reliably get cash gifts every year until you graduate from school and start working full-time.

In the digital age, however, they've become a way for Chinese tech companies to make a stack of money and attract new users and traffic.

In return, users have to follow increasingly complicated rules to get a few bucks, for example rewards for inviting friends to join the app, or spinning wheels of coupons. And these sorts of tactics are coming to the US and beyond, as apps like Temu expand. Read the full story.

How sulfur could be a surprise ingredient in cheaper, better batteries

The key to building less-expensive batteries that could extend the range of EVs might lie in a cheap, abundant material: sulfur.

Addressing climate change is going to require a whole lot of batteries, both to drive an increasingly electric fleet of vehicles and to store renewable power on the grid. Today, lithium-ion batteries are the dominant choice for both industries.

But as the need for more batteries grows, digging up the required materials becomes more challenging. The solution may lie in alternatives like lithium-sulfur, which could soon reach a major milestone, as startup Lyten plans to deliver limited quantities of lithium-sulfur cells to its first customers later this year.

The big story

Why we can no longer afford to ignore the case for climate adaptation

August 2022

Back in the 1990s, anyone suggesting that we'd need to adapt to climate change while also cutting emissions was met with suspicion. Most climate change researchers felt adaptation studies would distract from the vital work of keeping pollution out of the atmosphere to begin with.

Despite this hostile environment, a handful of experts were already sowing the seeds for a new field of research called climate change adaptation": study and policy on how the world could prepare for and adapt to the new disasters and dangers brought forth on a warming planet. Today, their research is more important than ever. Read the full story.
