Why It’s So Hot Underground

Back in the Middle Ages, miners noticed that the deeper they dug into the Earth, the hotter it got. Physicist William Thompson, aka Lord Kelvin of temperature fame, theorized that Earth started out hot and has been cooling ever since. He used the hypothesis to predict the age of our planet, but overshot the number by several million years. What was missing in his theory, was his failure to detect the rigidity of the Earth’s mantle, the layer between the crust and the core. MinuteEarth host Emily Elert explains further.

The Weirdness of Inheritance

Inheriting DNA cells can be weirder than you think. Chemical switches attached to DNA turn genes on and off or up and down, telling the machinery which proteins to produce and in what quantities. These swithces, called epigenetic tags, make for some very strange DNA passed down from our ancestors. Emily Elert explains in this fascinating edition of Minute Earth.

Avoiding the Next Atlantis

With many of our cities lying along coasts and waterways and with sea levels projected to rise in the future, keeping these land masses from going under is a major concern. Emily Elert of MinuteEarth says many nations have already devised quick fixes for the dilemma, such as “thirsty concrete,” which can absorb 600 liters of water per square liter and funneling it away, and floating homes.

Are We Really 99% Chimp?

Are we really 99 percent chimp? Science tells us there are similarities in our tangled genetic make-up, but there are plenty of mismatches, too. “We share 99 percent of our DNA with chimps if we ignore 19 percent of their genome and 25 percent of ours,” Emily Elert says. She sorts the numbers in this edition of Minute Earth.

Rain’s Dirty Little Secret

A touch of salt, a speck of soot, a grain of clay. Believe it or not, microscopic portions of one of these is present in every drop of rain. And they are also absolutely crucial to the existence of rain. Without these small pieces of dirt, there would be no rain at all.. Join Emily Elert in this edition of MinuteEarth.

Your Brain On Extreme Weather

Extreme weather, snowmaggedon and polar vortex are terms that have dominated your local weather channels. But MinuteEarth tells us that rain or shine, our minds tend to prize their freshest impressions. “Even when we experience the same weird weather events as other people, we don’t always agree on how weird they were,” says host Emily Elert. Even politics plays a major role.

Baby It’s Hot Down There

Lord William Thompson Kelvin, of absolute temperature fame, attempted and failed to determine why the heat of the Earth increased exponentially the deeper you descended. He theorized that Earth actually started off hot and had been cooling off ever since. Unfortunately for Kelvin, he failed to factor in radioactivity in the Earth’s core. In this edition of MinuteEarth, Emily Elert digs deeply into what really keeps the Earth’s core toasty.
