Can a strawberry a day keep dementia away? A study published in the journal Nutrients last month suggests that could be possible. Researchers from the University of Cincinnati (UC) studied a total of 30 patients between 50 and 65 years of age who had experienced symptoms of mild cognitive decline. The participants were told to avoid eating any berry fruit -- and instead added a packet of supplement powder to their water each morning, according to a press release from UC. For half the group, the powder contained strawberries.

Politics has become a technological arms race. In 2016, the Republicans fought back, using big-data analytics and microtargeting of online ads to help propel Donald Trump into the White House. Raffi Krikorian wants to get the Democrats out ahead again. As the chief technology officer of the Democratic National Committee, the MIT graduate is reshaping his party's tech strategy. Krikorian, an expert in software engineering, previously led Uber's Advanced Technologies Center and got its first fleet of driverless cars on the road.

The Democratic National Committee's chief technology officer, Raffi Krikorian, says that changes within the post-2016 political party are as much about the culture as they are about security. The MIT grad's time is physically split between his Silicon Valley home and Washington D.C., although he's looking to bridge the cultural gap between tech and politics. Krikorian previously led Uber's Advanced Technologies Center, where he was tasked with putting the ride-sharing company's self-driving cars on the streets of Pittsburgh, Pa. And preceding that, Krikorian was Twitter's vice president of engineering after successfully managing the social media giant's application programming interface. Following last year's hacks, leaks and ongoing discussion about Russian interference, his priority was to move security and communication to a trusted cloud service assisted by Microsoft.

If you are among the millions of Americans concerned about cybersecurity at the Democratic National Committee--and how could you not be?--then the home of the party's tech braintrust might not give you much hope. The tiny, charmless office, with "DNC Tech" scribbled in dry-erase marker on the door, contains one desk and two computer monitors. Nearby, an overturned couch pokes out from an elevator shaft, a leftover from the widespread departures that followed Hillary Clinton's defeat. And that, of course, came after intruders, believed to be tied to Russia, hacked into the DNC's computers. If the office itself seems lacking, the resume of its newish occupant is anything but.

A handful of people who order Ubers in Pittsburgh this morning will discover that their driver is less chatty than usual. And like those lucky riders, I got to experience being chauffeured around town in one of the company's experimental self-driving cars. I also got to sit behind the wheel and try driving--or, rather, supervising--one of Uber's new vehicles. "We're going to slowly start inviting our most loyal Pittsburgh riders to experience the future," says Raffi Krikorian, director of the Uber Advanced Technology Center in Pittsburgh. "If they call for a ride, then a self-driving Uber might turn up."

PITTSBURGH, PENNSYLVANIA – Taylor Pollier got an offer from Uber he couldn't refuse -- to be part of an experiment with a car of the future. Uber on Wednesday became the first company to make self-driving cars available to the general public in the U.S. through a test program in Pittsburgh. The ride-hailing service selected a group of customers, including Pollier, to take free rides in autonomous Ford Fusions, with human drivers as backups. Pollier, 27, said the Fusion "felt sharp," and the 15-minute ride to his bartending job went smoothly and felt "like taking an Uber any other day." If other riders have a similar reaction, and the autonomous cars are able to handle all the challenges Pittsburgh offers, including snowstorms, rolling hills and a tangled network of aging roads and bridges, then the self-driving car will be one step closer to going from science fiction to a realistic option for travelers.
