You are what you tweet: Twitter reveals how America eats and exercises

Add as a preferred source on Google

Twitter, it turns out, isn’t just about wacky hashtags and slandering celebrities anonymously.

A new tool developed by researchers at the University of Vermont’s Computational Story Lab — along with those at the University of California, Berkeley, Massachusetts Institute of Technology, and several others universities — is using the social network to track how America is eating and exercising.

Called the Lexicocalorimeter, it searches for thousands of activities and foods, and assigns them approximate calorie number, with the broad idea being that tagged phrases are split into “caloric input” and “caloric output” categories. These aren’t just your everyday “running” and “pushups” type exercises, either: the researchers have included the likes of “pole dancing” and “alligator hunting” among the things it’s looking for. Case in point: One of America’s favorite “activities” is watching television.

The goal is to see what kind of caloric balance exists around the United States, with positive examples being set by places like Colorado (“running” as activity, and “noodles” as food), while Mississippi sadly ranks at the other end of the spectrum (“eating” and “cake.”)

True, it’s not super accurate, but it’s the kind of insight that is only possible to start exploring in an age of social media.

“We’ve had an amazing explosion of information, with people expressing themselves online through social media,” Peter Dodds, a scientist at the University of Vermont, told Digital Trends. “This research is an attempt to use that to look at population health patterns on a country, state, and city basis.” He describes the results as a “dashboard of society.”

Eventually, it will be possible to monitor everything in real time but for now, you will have to settle for looking at the results of 50 million geo-tagged tweets from 2011 and 2012.

“On an individual level, I think this can be interesting because it allows you to compare yourself or your state to people living elsewhere in the country, for example,” Dodds continued. “You could also do the same over a period of time, which allows you to reflect on whether things are getting better or worse. From a city planner or policy-making perspective, it could also be incredibly important. If you can see these numbers in front of you, it would be possible to look at what happened in another city when they introduced a particular program to see whether it was effective.”

In all, it’s another amazing demonstration of the way that even seemingly throwaway social media comments are helping document the age we live in.

“Just imagine if we had these tools going back 100 years,” Dodds said. “You would see remarkable transformations taking place in the kinds of food and exercise that people talked about. Going forward, we hope that this lasts for a very long time.”

Robots just ran the Beijing half-marathon faster than the world record holder
humanoid robot running a marathon

A humanoid robot just ran a half-marathon faster than the world record holder. It might not seem impressive at first, but considering last year, the fastest robot at Beijing's humanoid robot half-marathon finished in two hours and 40 minutes, this is a huge achievement. 

As reported by the Associated Press, the winning robot at this year's Beijing half-marathon crossed the finish line in 50 minutes and 26 seconds, comfortably beating the human world record of 57 minutes recently set by Jacob Kiplimo.

As if the plate wasn’t already full, AI is about to worsen the global e-waste crisis
New report highlights a rising environmental concern

AI is already changing how the world works, but it’s also quietly making one of our biggest environmental problems even worse. And no, this isn’t about energy consumption this time. It’s about the hardware. Because every smarter AI model comes with a physical cost.

AI is about to supercharge the e-waste problem

Smart glasses are finding a surprise niche — Korean drama and theater shows
Urban, Night Life, Person

Every year, millions of people follow Korean content without speaking a word of the language. They stream shows with subtitles, read translated lyrics, and find workarounds. But live theater has always been a different problem — you can't pause or rewind it. That's the problem: a Korean startup thinks it's cracked, and Yuroy Wang was one of the first to try it. The 22-year-old Taipei retail worker is a K-pop fan who loves Korean culture but doesn't speak the language. When he went to see "The Second Chance Convenience Store," a touring play based on a Korean novel that was a bestseller in Taiwan, he expected supertitles. What he got instead was a pair of chunky black-framed AI-powered glasses sitting on his nose, translating the dialogue in real time directly on the lenses. "As soon as I found out they were available, I couldn't wait to try them," he said. Wang is part of a growing audience discovering that smart glasses, a category of tech that has struggled to find mainstream purpose for years, might have just found their calling in the most unexpected of places: live Korean theater.

How do the glasses work?
