Where did we come from? How did we get here? The Genographic Project—a joint effort of the National Geographic Society, in Washington, D.C., and IBM Corp.—aims to answer those big questions once and for all. Using genetic data from thousands of people around the world, it plans to construct a map of human migration, spanning millennia from our origins in Africa to the present.

If this is anthropology’s moon shot—as some say it is—then its chief rocket scientist is Ajay Royyuru, senior manager of the Computational Biology Center at IBM’s Thomas J. Watson Research Center, Yorktown Heights, N.Y. “We get to pursue an innovation that will hopefully touch every individual on the planet,” Royyuru says of the project. “You don’t get to do that all the time.”

The EV Transition Explained: Charger Infrastructure

How many, where, and who pays?

The ability to conveniently charge an EV away from home is a top concern for many EV owners. A 2022 survey of EV owners by Forbes indicates that 62 percent of respondents are so anxious about their EV range that travel plans have been affected. While “range anxiety” may be overblown, the need for an extensive and reliable external charging infrastructure is not.

Infrastructure terminology can itself be confusing. For clarity, bear in mind that a charging station is a specific physical location which has one or more charging posts. A charging post itself may have one or more ports, where each port can charge a single EV. Each post may have multiple types of service connectors to support different EV charging connector standards. And a port may supply varying power levels.
