From sequence to structure: A fast track for RNA modeling
In Biology 101, we learn that RNA is a single, ribbon-like strand of base pairs that is copied from our DNA and then read like a recipe to build a protein. But there's more to the story. Some RNA strands fold into complex ...

Growth before photosynthesis: How trees regulate their water balance
Plants have small pores on the underside of their leaves, known as stomata. When the sun rises, these pores open and the plants absorb carbon dioxide (CO2) from the atmosphere, which they need, in addition to sunlight and ...
