Neuroscience in Fiction: Crux, by Ramez Naam

Crux (Angry Robot Books) is an outstanding speculative fiction adventure. It combines the very highest level of neuroscientific reality with plausible neuroscience fiction that is very well thought through.

“Rangan felt her before he saw her. Felt them before he saw them. He didn’t understand what he sensed until the door swung open. She was seated in a swiveling office chair. A pretty petite blonde woman in a floral dress. Thirty, maybe. She had a shy smile on her face. And her hands were on her belly. Her giant pregnant belly.”

Crux (Angry Robot Books) is an outstanding speculative fiction adventure. It combines the very highest level of neuroscientific reality with plausible neuroscience fiction that is very well thought through. I loved it.

The techno-thriller is a sequel to Naam’s first novel, Nexus, describing the adventures of a young group of neuroscientists who change the world by developing a nanotech computer system that is ingested—to then intermingle with the neurons of the brain—providing the user with a mental Google glass-like computer interface (sans hardware) that overlays on their normal conscious experience. As I previously reviewed, Nexus was a terrific yarn and Raam established himself in the same league as Michael Crichton and Daniel Suarez for pure bitchin’ fun and coolness.

Crux, if anything, is even better. Naam truly reveals the depth of his imagination by delving deeply into the societal impacts of such an invention. Its ability to help people that suffer from neural diseases, such as people with autism or Alzheimer’s, to literally connect to the outside world. Its effects on human evolution, as parents began to directly communicate with intrauterine fetuses months before birth. Its ability to download Bruce Lee-like Kung Fu knowledge ala The Matrix. Its nefarious uses as a mind control agent. And its sublime ability to create a new level of consciousness as post-humans truly begin to form hive-like minds that transcend genius with super problem-solving capabilities (which, come to think of it, is a surprising lacuna in The Matrix saga given the overlap in the whole let’s-network-our-brains theme). Crux’s adventure, appropriately, centers around how dumb it would be to give such device to flawed creatures, like human beings. I won’t give anymore of the plot away because I really do think you should put it at the top of your summer reading list. You’re welcome!

Crux will be released on August 27, and is available for pre-order now at your favorite bookseller. If you haven’t done so already, get Nexus first and finish it before the Crux’s release.

Enjoy! And please come back and leave your comments when you’re done!

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
