If the past few months have taught us anything, it's that everything we do online leaves a digital trail. While it may seem like there's not much we can do about it, there are some tech companies that are working to obscure that trail a little bit, with a process known as encryption.
Oklahoma was hit particularly hard by two massive outbreaks this year in what's been another deadly season of tornadoes in the U.S. Despite technology and forecasting improvements, scientists still have plenty to learn about how and why tornadoes form.
Currently, one of the best ways for researchers to understand how tornadoes form is to chase them. So off they go with mobile science laboratories, rushing toward storms armed with research equipment and weather-sensing probes.
