The Download: extending dogs’ lives, and sex and the immune system
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.
These scientists are working to extend the lifespan of pet dogs—and their owners
Matt Kaeberlein is what you might call a dog person. He has grown up with dogs and describes his German shepherd, Dobby, as “really special.” But Dobby is 14 years old—around 98 in dog years. “I’m very much seeing the aging process in him,” says Kaeberlein, who studies aging at the University of Washington in Seattle.
Kaeberlein is co-director of the Dog Aging Project, an ambitious research effort to track the aging process of tens of thousands of companion dogs across the US. He is one of a handful of scientists on a mission to improve, delay, and possibly reverse that process to help them live longer, healthier lives.
But dogs are just the beginning. Because they’re a great model for humans, anti-aging or lifespan-extending drugs that work for dogs could eventually benefit people, too. In the meantime, attempts to prolong the life of pet dogs can help people get onboard with the idea of life extension in humans. Read the full story.

The quest to show that biological sex matters in the immune system
For years, microbiologist Sabra Klein has painstakingly made the case that sex—defined by biological attributes such as our sex chromosomes, sex hormones, and reproductive tissues—can influence immune responses.
Through research in animal models and humans, Klein and others have shown how and why male and female immune systems respond differently to the flu virus, HIV, and certain cancer therapies, and why most women receive greater protection from vaccines but are also more likely to get severe asthma and autoimmune disorders (something that had been known but not attributed specifically to immune differences.)
In the 1990s, scientists often attributed such differences to gender rather than sex—to norms, roles, relationships, behaviors, and other sociocultural factors as opposed to biological differences in the immune system. Klein has helped spearhead a shift in immunology, a field that long thought sex differences didn’t matter—and she’s set her sights on pushing the field of sex differences even futher.

The big story
Art has been brutalized by tech’s giants. How can it survive?
December 2020
There are two stories you hear about making a living as an artist in the digital age, and they are diametrically opposed. One comes from Silicon Valley and its boosters in the media. There’s never been a better time to be an artist, it goes, if you’ve got a laptop, you’ve got a recording studio. Everyone’s an artist; just tap your creativity and put your stuff out there.
The other story comes from artists themselves. Sure, you can put your stuff out there, but who is going to pay you for it? Making art takes years of dedication, and that requires a means of support. If things don’t change, a lot of art will cease to be sustainable.
Yet people are still making art. More people than ever, in fact. So how are they managing to do it? Are the new conditions tolerable? Are they sustainable? And what does it mean, in specific practical terms, to function as an artist in the 21st-century economy? Read the full story.
