Twin Tales
Tazeen Ulhaque
Whitney Alexandra Tuoti
Have you ever wondered why some twins look so alike and other siblings may not? Let’s explore how twins form in the womb and how they may grow up to be similar or different.
Confronting Human Chimerism
Tazeen Ulhaque
Most people have just one set of DNA throughout their body. But what happens to humans who are born with two sets?
Cells, Frozen in Time
Risa Aria Schnebly
If a living organism freezes, it can die. But by freezing living cells at just the right temperature, scientists can preserve living cells instead of killing them.
CRISPR Crops
Imagine you are a farmer. You may love the fresh fruits and vegetables that you grow on your farm, but growing them is a lot of hard work. Growing better crops that are bigger, more nutritious, or less likely to die before harvest would make farming much easier. It would also let you grow more food for more people. But better crops are not easy to come by. Building better food is one of the ideas behind using CRISPR to edit the genes of many crops.
CRISPR: One Tool, Many Uses
If you’ve ever done a word search puzzle, you know it can be hard to find short sequences of letters among lots of other letters. An average word search has maybe 400 letters, and has a lot of variation, with all the letters of the alphabet. But searching the genome for a specific sequence is much, much harder.
Cutting DNA with CRISPR
Christian H. Ross
What is gene editing? And how does the one of the most-used gene editing tools, called CRISPR, work?

Building at a Nanoscale
Tyler Rockwood
Nicholas Stephanopoulos works with tiny structures so small you can only see them by using powerful microscopes. Some might say he's a builder, but he actually gets the molecules to do the building themselves.
