But it’s additionally political: a query of the extent to which decarbonization can, or ought to, usher in a broader transformation of rail transportation.

In the insular world of railroading, this hydrogen-powered prepare is a Rorschach take a look at. To some, it represents the way forward for rail transportation. To others, it seems to be like a giant, shiny distraction. Read the complete story.

Researchers taught robots to run. Now they’re educating them to stroll

We’ve all seen movies over the previous few years demonstrating how agile humanoid robots have turn into, operating and leaping with ease. We’re not stunned by this sort of agility—in truth, we’ve grown to count on it.
