Just about every solid, liquid, or gas in the world as we know it begins with reactions between individual atoms and molecules. Host David Pogue dives into the transformative world of chemical reactions, from the complex formula that produces cement to the single reaction that’s allowed farmers to feed a global population by the billions.

Glass so strong you can jump on it, rubber so tough it protects a clay pot dropped from 50 feet, endless varieties of plastic. Scientists and engineers have created virtually indestructible versions of common materials by manipulating the chains of interlocking atoms that give them strength—but have they made them too tough? Host David Pogue explores the fantastic chemistry behind the everyday.

Without the chemistry of photosynthesis, ozone, and a molecule called Rubisco, none of us would be here. So how did we get so lucky? To find out, host David Pogue investigates the surprising molecules that allowed life on Earth to begin, and ultimately thrive. Along the way, he finds out what we’re all made of—literally.

In the non-coding 98% of our DNA, we have countless switches to promote or suppress the physiological reactions of our bodies. Interestingly, we can change the states of these switches through our own efforts and even can affect the DNA conditions of our offspring before their birth.

Some 30 million Americans have sent their DNA to be analyzed by companies like 23andMe and AncestryDNA. But what happens once the sample is in the hands of testing companies, and how accurate are their results? NOVA explores the power of genetic data to reveal family connections, ancestry, and health risks—and even solve criminal cold cases.
