The Download: what’s next for quantum computing, and hacking circadian clocks – MIT Technology Review

Plus: a new covid variant is working its way across the US
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.
What’s next for quantum computing
For years, quantum’s news cycle was dominated by headlines about record-setting systems. But this year, researchers are getting off the hype train and knuckling down to life in the real world—bucking the trend of packing processors with ever more quantum bits, or “qubits,” in favor of fewer, but higher quality qubits.
Companies are also announcing new chips designed to connect directly to each other. It’s a move that’s expected to accelerate the shift toward “modular” quantum computers—and help the machines to scale up significantly in the process. Read the full story.

How drugs that hack our circadian clocks might one day improve our health
We’ve got more than one biological clock. Beyond the one that marches onwards as we age, the circadian clock that sits in our brains keeps our bodies in rhythm. This clock helps control when we wake, eat, and sleep.
But there’s more to it than that. It also controls the finer aspects of how our bodies work, by influencing hundreds of molecular clocks throughout our cells and organs, from regulating our metabolisms to controlling how our genes make proteins.
Now scientists are working on ways to tailor treatments to our circadian rhythms. Drugs that specifically target the clocks themselves are being explored in the lab. Will we one day be able to hack our circadian clocks to improve our health? Read the full story.

The big story
Your first lab-grown burger is coming soon—and it’ll be “blended”
December 2020
One cool fall night in 2010, Jessica Krieger was horrified by a documentary that showed the gruesome ways animals are slaughtered for food. Then an undergrad in neuroscience, she threw herself into what at the time was a fringe area of biotech research: growing and harvesting edible animal cells without killing any sentient creatures.
While lab-grown meat was busy trying to find its way out of the petri dish, plant-based meat substitutes were undergoing a revolution. But rather than treating their success as a threat, Krieger and a number of other entrepreneurs see it as the opening they need to finally bring their creations to market—in the form of “blended meat,” melding the best of the plant-based and cultured-meat substitutes. And it might not be long before you get a chance to taste it. Read the full story.
