The end of passwords

For decades, weve needed passwords to do things online. New forms of authentication will finally let us get rid of them for good. Instead, well use a link sent via email, a push notification, or a biometric scan. Not only are these methods easieryou dont have to remember your facebut they tend to be more secure.

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.

Were 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. Theyre made using abundant materials and could be cheaper and more practical than other types of grid storage.
