One of the rarest animal adaptations in the world happens in the winter in Colorado
Winter is hard, and for wildlife in Colorado, it’s even harder. To survive, many species have developed adaptations over hundreds of thousands of years that allow them to weather the storms, including hibernation, thicker coats, food storage and…

Mathematicians crack cellular noise puzzle, paving path for better cancer treatment
Why does cancer sometimes recur even after successful treatment, or why do some bacteria survive despite the use of powerful antibiotics? One of the key culprits identified is “biological noise”—random fluctuations occurring inside cells.
