Dr. Cary Oberije, a postdoctoral researcher in The Netherlands, has found that mathematical models can be used to accurately predict patients' responses to treatment. Prediction models were used to analyze lung cancer patients' likelihood of survival and...

# DNA Calculators

Turns out that DNA, the molecule of life, can double as a calculator.

Researchers at Caltech have designed a circuit made from strands of DNA that can add and subtract numbers and even calculate square roots. In this new method, each strand of DNA represents 1's and 0's, the binary numbers used in digital circuits. Researchers can design a DNA molecule to represent a specific number then coax this molecule to interact with other DNA molecules. After the strands of DNA undergo their natural processes of zipping and unzipping, new DNA strands emerge, and the original strand now represents a new binary number--the solution to the math problem. Read more about the amazing study that has major implications for both genetics and mathematics.

The most common question students ask math teachers at every level is “When will I use math?” WeUseMath.org is a non-profit website that helps to answer this question. This website describes the importance of mathematics and many rewarding career opportunities available to students who study mathematics.
