10 Breakthrough Technologies
THE END OF PASSWORDS
For decades, we’ve needed passwords to do things online. New forms of authentication will finally let us get rid of them for good. Instead, we’ll use a link sent via email, a push notification, or a biometric scan. Not only are these methods easier—you don’t have to remember your face—but they tend to be more secure.
COVID VARIANT TRACKING
The pandemic brought unprecedented investment in genomic sequencing and dramatically expanded the capacity for this type of monitoring around the world. Better surveillance has allowed scientists to track the spread of the covid virus and to quickly spot and warn about new variants.
A LONG-LASTING GRID BATTERY
We’re using more renewable power than ever. But what happens when the sun sets or the wind stops? Grid operators need a way to store electricity for later. New iron-based batteries may be up to the task. They’re made using abundant materials and could be cheaper and more practical than other types of grid storage.
AI FOR PROTEIN FOLDING
Nearly everything your body does, it does with proteins. And the way a protein folds determines its activity. But figuring out proteins’ structure can take months. Now an AI called AlphaFold2 has solved this longstanding biological puzzle, which could make it possible to quickly design drugs for a wide range of diseases.
Malaria kills more than 600,000 people a year, most of them children younger than five. A new malaria vaccine approved by the World Health Organization could help save hundreds of thousands of lives every year. It’s also the world’s first vaccine for a parasitic infection.
PROOF OF STAKE
Cryptocurrencies like Bitcoin use huge amounts of electricity. This is due to the way transactions are verified, which now requires significant computing power. Proof of stake offers a way to verify transactions without using so much energy. Ethereum plans to transition to the system this year, cutting energy use by 99.95%.
