Conscious ‘Alien Minds’ Could Be Living Among Us—And We Don’t Even Know It, Scientist Says

What is intelligence? We can all agree that humans are intelligent and many of us would likely extend that definition to the most mentally adept creatures of the animal kingdom—from dolphins to corvids. Scientists may extend that definition to all living animals, and some might even include plants. But for Michael Levin, Ph.D., all of those definitions woefully undercount the intelligences, or as he phrases them, “alien minds,” that surround us.

As a synthetic and developmental biologist at Tufts University in Massachusetts, Levin has explored the cognitive glue of bioelectricity, created biobots from animal and human cells, searched for empirical evidence defining the scope of cognition, and challenged many of the long-held tenets of molecular biology. Fascinated by electrical engineering and biology since he was seven years old, Levin says all of these efforts are in service of developing a mature field of diverse intelligence—one that can recognize that cognition lies on a spectrum, and that what humans perceive as consciousness could look radically different when compared to a cell or emerging artificial intelligence.

We spoke with Levin about how he developed these remarkable ideas, why he believes many alien minds live among us, and what he hopes for humanity’s future.

Euclid captures 26 million galaxies in vivid deep field photos

Each one gives scientists a powerful tool to study how dark matter is spread out across the Universe and how galaxies are shaped by it.

“We are combining the strengths of Euclid, AI, citizen science, and experts into a single discovery engine,” said Pierre Ferruit, ESA’s Euclid mission manager.

Next-generation AI hardware: 3D photonic-electronic platform boosts efficiency and bandwidth

Artificial intelligence (AI) systems promise transformative advancements, yet their growth has been limited by energy inefficiencies and bottlenecks in data transfer. Researchers at Columbia Engineering have unveiled a groundbreaking solution: a 3D photonic-electronic platform that achieves unprecedented energy efficiency and bandwidth density, paving the way for next-generation AI hardware.

The study, “3D Photonics for Ultra-Low Energy, High Bandwidth-Density Chip Data Links,” led by Keren Bergman, Charles Batchelor Professor of Electrical Engineering, is published in Nature Photonics.

The research details a pioneering method that integrates photonics with advanced complementary-metal-oxide-semiconductor (CMOS) electronics to redefine energy-efficient, high-bandwidth data communication. This innovation addresses critical challenges in data movement, a persistent obstacle to realizing faster and more efficient AI technologies.
