Episodes 15
3D Printing Mars Habitats
NASA invited engineers and architects from around the world to design future habitats for Mars. Here's what they came up with.
Read MoreInside a Synthetic DNA Factory
In this DNA factory, organism engineers are using robots and automation to build completely new forms of life.
Read MoreDesigner Pathogens
Engineered bioweapons are the new security threat.
Read MoreRadioactive Carbon
The amount of carbon-14 doubled in our atmosphere between 1955 and 1963, a time when nuclear bomb tests were popping off in the desert. Bomb carbon is still everywhere: in our tissues, in the environment, and even in the deepest parts of the ocean.
Read MoreThe Hunt for Dark Energy Is On
The Dark Energy Spectroscopic Instrument (DESI) will measure dark energy's effect on the expansion of the universe. We dive into the mysteries of dark energy, the engineering behind DESI and what it may discover about the force that governs our universe.
Read MoreSelf-Aware Robots
At Columbia's Creative Machines Laboratory, Hod Lipson and his students are building consciousness from the ground up. Starting with the most basic definition of what it means to be self-aware, they're building robots that can "imagine themselves."
Read MoreOur Solar System's Edge
Since launching in 1977, the Voyager space probes have traveled farther from Earth than any other man-made object. They've observed planets, swept past the Sun, and have left our solar system for a new great beyond for mankind: the interstellar medium.
Read MoreSilicon Chips' Next Frontier
Moore's Law is the golden rule in computing: the number of transistors on a microchip doubles every two years, while the cost halves. We've hit a physical limit on how small these transistors can get, but a few chipmakers are betting big on something new.
Read MoreThe Superheavy Atom Factory
We've been slowly filling out the periodic table since the late 1800s. But as we push the periodic table farther and farther into the unknown, its familiar columns and rows are threatening to crumble under the weight of bizarre superheavy elements.
Read MoreWhat Cells Actually Look Like
There's a revolution happening in the field of biology thanks to a wave of new imaging techniques. One of the newly invented microscopes can capture 3D images and videos of cells inside living organisms to a scale never seen before.
Read MoreExotic Matter in Space
Atomic physicists have built a cold-atom laboratory that can probe the strange and curious quantum world up close.
Read MoreDeepfakes Aren't Going Away
Since 2017, deepfakes have taken the internet by storm, rising to a point where politicians are worried that these altered videos could sway elections and even pose a national security threat.
Read MoreRocket-Powered Car
Since 1997, the record for the world's fastest car has been held by Thrust SSC, which‚ travelling at 763 mph‚ became the very first car to break the sound barrier. Now, 22 years later, the same engineering team is looking to beat their own record.
Read MoreMoon Water to Rocket Fuel
Long the stuff of science fiction, mining for resources on the Moon is starting to come into focus. We meet a team of engineers who are figuring out how to turn the Moon's billion-year-old water into rocket fuel and breathable oxygen for astronauts.
Read MoreThe New Dark Matter Particle
When it comes to dark matter, it might be time to leave WIMPS behind, as there's a new candidate that's been pulling ahead of its competitors in recent months: axions. Welcome to the new era of dark matter hunting.
