We use algorithms every day for things like image searches, predictive text, and securing sensitive data. But algorithms show up all over nature, too, in places like your immune system and schools of fish—and computer scientists have learned a lot from studying them.
If our efforts to automate trains are any indication, the cars and trucks of the future may be more dependent on human help than we imagine.
There are labs so silent that many people can't stand being inside them, but that stillness lets us run some of our most sensitive experiments.
Randomness is important for all kinds of things, from science to security, but to generate true randomness, engineers have turned to some pretty odd tricks.
What are the methods twitter bots use to fool us, and what are some of the challenges in doing so?
As midterm political campaigns shift into full gear, start-ups are pushing for blockchain-based voting.
