Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these systems ...

In recent years, researchers in the messy world of biology have been able to build systems that function like the clean, binary switches on computer chips—and we've covered a number of reports in this ...

Don’t feel like shelling out $5 for a fancy factory made calculator that won’t even do binary math? [Jeff] decided to prove his mastery of gates and his disdain for base 10 by building a binary ...

You can use the circuit described in this DesignIdea to estimate voltages across 10- to 100-MΩresistances. It also works for reverse-biased diodes. The common CMOS gates in Figure 1 have aninput ...
