You’re looking at a rabbit’s heart beating outside the animal that once hosted it. It’s alive, pumping blood on its own thanks to a revolutionary electronic membrane that may save your life by keeping your heart beating at a perfect rate.
This is a game changer, folks. Whereas mining stem cells has been either an ethical quandary or a months-long affair, scientist can now turn any old blood cells into stem cells in just 30 seconds by dipping them in acid.
For the first time, scientists have succeeded in transforming human stem cells into functional lung and airway cells. The advance has significant potential for modeling lung disease, screening drugs, studying human lung development, and, ultimately, generating lung tissue for transplantation.
An experimental device is letting paralyzed people drive wheelchairs simply by flicking their tongue in the right direction. Key to this wireless system: Users get their tongue pierced with a magnetic stud that resembles jewelry and acts like a joystick, in hopes of offering them more mobility and independence.
When cloud formations take physical shape, neither their scale nor duration has an upper bound: We may begin to see cloud towns, then cloud cities, and ultimately cloud countries. At first this sounds rather implausible. Perhaps the internet will spur a wave of internal migrations as online communities begin gathering in person — but could this process really lead to a new city, or country?
Where does consciousness come from? According to Koch, consciousness arises within any sufficiently complex, information-processing system. All animals, from humans on down to earthworms, are conscious; even the internet could be. That’s just the way the universe works.
We literally have the ability to tell stories in ways not possible before this in human history. Plays, books, radio, movies and TV all changed the way stories were delivered, but not the fundamental structures of the stories told or the relationship between the storyteller and the audience. With immersive, open-ended, multi-user worlds, we no longer have one teller and many listeners; instead we have thousands or millions of points of view in the same world at the same time, creating meaning out of their actions and events in the world. With this, for the first time we have the potential to create new kinds of stories: stories that, in one way to put it, are asked, not told.—Mike Sellers, video game designer and AI researcher
