Presented by Ben Ofori-Okai. Earth’s magnetic field does more than just help us to navigate. It is also used by animals for orientation and migration,  and it protects life on Earth from charged particles that stream in from the sun...

Presented by Franklin Fuller. Over billions of years, plants and cyanobacteria changed the Earth’s atmosphere by inhaling carbon dioxide, storing the carbon in solid biomass and exhaling oxygen.

Presented by Justin Myles. As the universe expanded from the Big Bang, regions where the density of matter was higher than average grew into galaxies and clusters of galaxies.

Presented by Aaron Lindenberg. As we reach the limits of high-speed computation based on silicon, ideas for the next generation of computers have focused on electrically switchable nanoscale devices that operate in ways similar to the neurons and synapses of...

Presented by Arianna Gleason. When and where life originated on Earth – and if, or where, life exists elsewhere in the cosmos – are some of the biggest scientific questions of our time.

Presented by Caterina Vernieri. The Higgs boson was discovered in 2012 at the world’s most powerful particle collider, the Large Hadron Collider (LHC) in Geneva, Switzerland.

Presented by Yijin Liu. In batteries, energy is stored in tiny particles within the electrodes that individually breathe in and out and chemically evolve as the battery is charged and discharged.

Presented by Diana Gamzina. In particle accelerators, electrons are pushed to extreme energies by electromagnetic fields that oscillate inside evacuated metal cavities. Those cavities are usually made of copper.

Presented by Zeeshan Ahmed. Shortly after the birth of the universe, space was filled by a plasma that was literally red-hot. The light radiated by that plasma has traveled the vast emptiness of space for billions of years, with the...

Presented by Nick Edwards. Until recently, the colors of ancient life forms existed only in our imaginations.
