The Download: sodium-ion batteries and China’s bright tech future
Plus: This company is developing gene therapies for muscle growth, erectile dysfunction, and “radical longevity”
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.
Sodium-ion batteries are making their way into cars—and the grid
For decades, lithium-ion batteries have powered our phones, laptops, and electric vehicles. But lithium’s limited supply and volatile price have led the industry to seek more resilient alternatives. Enter: sodium-ion batteries.
They work much like lithium-ion ones: they store and release energy by shuttling ions between two electrodes. But unlike lithium, a somewhat rare element that is currently mined in only a handful of countries, sodium is cheap and found everywhere. Read why it’s poised to become more important to our energy future.

Sodium-ion batteries are one of MIT Technology Review’s 10 Breakthrough Technologies this year. Take a look at what else made the list.
CES showed me why Chinese tech companies feel so optimistic
—Caiwei Chen
I decided to go to CES kind of at the last minute. Over the holiday break, contacts from China kept messaging me about their travel plans. After the umpteenth “See you in Vegas?” I caved. As a China tech writer based in the US, I have one week a year when my entire beat seems to come to me—no 20-hour flights required.
CES, the Consumer Electronics Show, is the world’s biggest tech show, where companies launch new gadgets and announce new developments, and it happens every January. China has long had a presence at CES, but this year it showed up in a big way. Chinese companies showcased everything from AI gadgets to household appliances to robots, and the overall mood among them was upbeat. Here’s why.

This company is developing gene therapies for muscle growth, erectile dysfunction, and “radical longevity”
At some point this month, a handful of volunteers will be injected with experimental gene therapies as part of an unusual clinical trial. The drugs are potential longevity therapies, says Ivan Morgunov, the CEO of Unlimited Bio, the company behind the trial.
The volunteers—who are covering their own travel and treatment costs—will receive a series of injections in their arms and legs. One of the therapies is designed to increase the blood supply to those muscles. The other is designed to support muscle growth. The company hopes to see improvements in strength, endurance, and recovery. It also plans to eventually trial similar therapies in the scalp (for baldness) and penis (for erectile dysfunction).
However, some experts warn the trial is too small, and likely won’t reveal anything useful. Read the full story.

AI is coming for music, too
While large language models that generate text have exploded in the last three years, a different type of AI, based on what are called diffusion models, is having an unprecedented impact on creative domains.
By transforming random noise into coherent patterns, diffusion models can generate new images, videos, or speech, guided by text prompts or other input data. The best ones can create outputs indistinguishable from the work of people.
Now these models are marching into a creative field that is arguably more vulnerable to disruption than any other: music. And their output encapsulates how difficult it’s becoming to define authorship and originality in the age of AI. Read the full story.
