Skeptic Check: Monster Mashup
ENCORE Monsters don’t exist. Except when they do. And extinction is forever, except when it isn’t. So, which animals are mythical and which are in hiding? Bigfoot sightings are plentiful, but real evidence for the hirsute creature is a big zilch. Yet,...
Raising the Minimum Age
We all try to fight it: the inexorable march of time. The fountain of youth doesn’t exist, and all those wrinkle creams can’t help. But modern science is giving us new weapons in the fight against aging. So how far are we willing to go? Hear when...
Archeologists continue to hunt for the city of Atlantis, even though it may never have existed. But, what if it did? Its discovery would change ancient history. Sometimes when we dig around in the past, we can change our understanding of how we got to...
Power to the People
ENCORE Let there be light! Well, it’s easy to do: just flip a switch. But it took more than the invention of the light bulb to make that possible. It required new technology for the distribution of electricity. And that came, not so much from Thomas...
Microbes: Resistance is Futile

Surviving the Anthropocene
The world is hot, and getting hotter. But higher temperatures aren’t the only impact our species is having on mother Earth. Urbanization, deforestation, and dumping millions of tons of plastic into the oceans … these are all ways in which humans are...
Today, scientists are familiar to us, but they weren’t always. Even the word “scientist” is relatively modern, dating from the Victorian Era. And it is to that era we turn as we travel to the University of Notre Dame to celebrate the 150th anniversary...
Skeptic Check: Your Inner Lab Coat
herlock Holmes doesn’t have a science degree, yet he thinks rationally – like a scientist. You can too! Learn the secrets of being irritatingly logical from the most famous sleuth on Baker Street. Plus, discover why animal trackers 100,000 years ago...
Digging Our Past
ENCORE What’s past is prologue. For centuries, researchers have studied buried evidence – bones, teeth, or artifacts – to learn about murky human history, or even to investigate vanished species. But today’s hi-tech forensics allow us to analyze...
Skeptic Check: Mummy Dearest
ENCORE Shh …mummy’s the word! We don’t want to provoke the curse of King Tut. Except that there are many curses associated with this fossilized pharaoh – from evil spirits to alien malevolence. So it’s hard to know which one we’d face. We’ll unravel...

How to Talk to Aliens

Skeptic Check: Got a Sweet Truth?
ENCORE The sweet stuff is getting sour press. Some researchers say sugar is toxic. A new study seems to support that idea: mice fed the human equivalent of an extra three sodas a day become infertile or die. But should cupcakes be regulated like...
Science Fiction True
Don’t believe everything you see on TV or the movies. Science fiction is just a guide to how our future might unfold. It can be misleading, as anyone who yearns for a flying car can tell you. And yet, sometimes fantasy becomes fact. Think of the...
Electricity is so 19th century. Most of the uses for it were established by the 1920s. So there’s nothing innovative left to do, right? That’s not the opinion of the Nobel committee that awarded its 2014 physics prize to scientists who invented the...
It’s the most dramatic technical development of recent times: Teams of people working for decades to produce a slow-motion revolution we call computing. As these devices become increasingly powerful, we recall that a pioneer from the nineteenth...
