Dark Matter How Does it Explain a Star s Speed Don Lincoln
All the stars in a spiral galaxy rotate around a center -- but to astronomers, the speed that each star travels wasn't making sense. Why didn't stars slow down toward the edges as expected? Don Lincoln explains how a mysterious force called dark matter is (possibly) the answer -- and why the search for an answer matters.
What s Invisible More Than You Think John Lloyd
Gravity. The stars in day. Thoughts. The human genome. Time. Atoms. So much of what really matters in the world is impossible to see. A stunning animation of John Lloyd's classic TEDTalk from 2009, which will make you question what you actually know.
Why Can T Some Birds Fly Gillian Gibb
Though the common ancestor of all modern birds could fly, many different bird species have independently lost their flight. Flight can have incredible benefits, especially for escaping predators, hunting and traveling long distances. But it also has high costs: consuming huge amounts of energy and limiting body size and weight. Gillian Gibb explores what makes birds give up the power of flight.
This Mushroom Will Kill You Before You Know What s Happening Michael Beug
Humans have known about the toxicity of death cap mushrooms for millennia. Yet they continue to pose a significant threat to unsuspecting foragers and mushroom hunters throughout the world. Today, death caps are responsible for more than 90% of all mushroom related deaths, killing upwards of 100 people each year. So, what makes this one species of mushroom so dangerous? Michael Beug investigates.
The Race to Decode a Mysterious Language Susan Lupack
In the early 1900s, archaeologist Sir Arthur Evans uncovered nearly 3,000 tablets inscribed with strange symbols. He thought the script, dubbed Linear B, represented the Minoan language, while others came up with their own theories. Was it the lost language of the Etruscans? Or an early form of Basque? Its meaning would elude scholars for 50 years. Susan Lupack explores the mysterious inscriptions.
How the Covid 19 Vaccines Were Created so Quickly Kaitlyn Sadtler and Elizabeth Wayne
In the 20th century, most vaccines took over a decade to research, test, and produce. But the vaccines for COVID-19 were cleared for emergency use in less than 11 months. The secret behind this speed is a medical technology that’s been developing for decades: the mRNA vaccine. So how do these revolutionary vaccines work? Kaitlyn Sadtler and Elizabeth Wayne dig into the science of mRNA technology.
How Do Our Brains Process Speech Gareth Gaskell
The average 20-year-old knows between 27,000 and 52,000 different words. Spoken out loud, most of these words last less than a second. With every word, the brain has a quick decision to make: which of those thousands of options matches the signal? And about 98% of the time, the brain chooses the correct word. How is this possible? Gareth Gaskell digs into the complexities of speech comprehension.

A Digital Reimagining of Gettysburg Anne Knowles
Geographer Anne Knowles uses digital technologies to reimagine the past. In this fascinating talk, Knowles transports us to the Battle of Gettysburg, the turning point of the Civil War. Using Geographic Information Systems (GIS) and historical maps, she traces the footsteps of Robert E. Lee as he orders Pickett’s Charge -- and makes an educated guess why he made this crucial mistake.
Mysteries of Vernacular Keister Jessica Oreck and Rachael Teel
Originally meaning a woven container, the word keister has roots all over the place. The devil’s tool box? Sure. A safe? That too. So, how did it become associated with the buttochs? Jessica Oreck and Rachael Teel get to the bottom of the word keister.
Can Machines Read Your Emotions Kostas Karpouzis
Computers can beat us in board games, transcribe speech, and instantly identify almost any object. But will future robots go further by learning to figure out what we’re feeling? Kostas Karpouzis imagines a future where machines and the people who run them can accurately read our emotional states — and explains how that could allow them to assist us, or manipulate us, at unprecedented scales.

The Basics of Boson Dave Barney and Steve Goldfarb
In 2012, scientists at CERN discovered evidence of the Higgs boson. The what? The Higgs boson is one of two types of fundamental particles and is a particular game-changer in the field of particle physics, proving how particles gain mass. Using the Socratic method, CERN scientists Dave Barney and Steve Goldfarb explain the exciting implications of the Higgs boson.
What Has No Ears but Can Still Hear Jakob Christensen Dalsgaard
The world is always abuzz with sounds, many of which human ears simply can’t hear. However, other species have extraordinary adaptations that grant them access to realms of sonic extremes. And some of them don’t even have ears— at least, not like we typically imagine. So, which is the best listener? Jakob Christensen-Dalsgaard explores the auditory capabilities of the animal kingdom.
How to Fossilize Yourself Phoebe a Cohen
You can aspire to great things in life, but how about in death? Could you be one of the world’s greatest fossils many years from now? To ensure being found by a future paleontologist, you'll need to die in a highly specific way (think within tree sap or on the bottom of the ocean floor), and nature takes care of the rest. Phoebe A. Cohen details the steps your body must take to find future fame as a fossil.
