Scientists Say: Model
Models are representations of real-life systems or processes that we use to ask questions, make predictions and test our knowledge.

Bacterial fossils exhibit earliest hints of photosynthesis
Microscopic fossils from Australia suggest that some bacteria evolved structures for oxygen-producing photosynthesis by 1.78 billion years ago.
- Math
Geometry can shape our world in unexpected but useful ways
This math, and the geometers who use it, can solve problems from how to stack oranges to designing better vaccines.
- Space
This space physicist uses radios to study eclipses
Nathaniel Frissell uses radio data to study how eclipses affect a layer of the atmosphere called the ionosphere.

Scientists Say: 2-D Material
Two-dimensional materials such as graphene could improve electronics, carbon capture and more.
- Animals
Have you seen Bigfoot or the Loch Ness Monster? Probably not
Floe Foxon is a data scientist by day. In his free time, he applies his skills to astronomy, cryptology and sightings of mythical creatures.

How much fruit can you pull from a display before it topples?
About 10 percent of the fruit in a tilted market display can be removed before it will crash down, computer models show.

Let’s learn about graphene
Scientists have been trying to understand and harness this material’s superpowers since its discovery in 2004.
- Physics
Neutrons are unveiling hidden secrets of fossils and artifacts
Images made with these particles have revealed details of dinosaur bones, mummies and more.
- Climate
Chemists make device to destroy planet-warming methane pollution
It can slash diffuse sources of this extremely potent greenhouse gas, such as from livestock barns and other sites.
- Tech
Synthetic biology aims to tackle disease and give cells superpowers
DNA machines and protein-mimicking nanotech could replace broken machinery in cells or even lead to made-from-scratch synthetic life.

Before the ancient Egyptians, nature may have carved sphinxes
Steady ‘winds’ can carve clay blobs into lion-shaped landforms called yardangs, a new study suggests. One such yardang may have inspired the Great Sphinx of Giza.
