AI Maps the Mood of Your City — And It’s Surprisingly Accurate
What if a city’s mood could be mapped like weather? Researchers at the University of Missouri are using AI to do exactly that—by analyzing geotagged Instagram posts and pairing them with Google Street View images, they’re building emotional maps of urban spaces.
These “sentiment maps” reveal how people feel in specific locations, helping city planners design areas that not only function better but also feel better. With potential applications ranging from safety to disaster response, this human-centered tech could soon become part of the city’s real-time dashboard.

Growing evidence for evolving dark energy could inspire a new model of the universe
The birth, growth and future of our universe are eternally fascinating.
In the last decades, telescopes have been able to observe the skies with unprecedented precision and sensitivity.
Our research team on the South Pole Telescope is studying how the universe evolved and has changed over time. We have just released two years’ worth of mapping of the infant universe over 1/25th of the sky.
Climbing the social ladder: A clear understanding of connections matters more than popularity, study suggests
Climbing the social ladder isn’t simply a matter of popularity. Rather, people in positions of influence are particularly adept at forming “maps” of their social connections, which they navigate to become prominent in their social network, new research shows.
It’s like having a “social superpower,” according to study author Oriel FeldmanHall, an associate professor of cognitive and psychological sciences at Brown University who is affiliated with the University’s Carney Institute for Brain Science.
“People vary considerably in how accurately they understand the structure of their communities,” FeldmanHall said. “Our research establishes for the first time that people who excel at mapping out their social network—determining who belongs to which communities and cliques—are the ones who will go on to become the most influential in the social network.”
Neuroscientists discover brain cells that drive intelligent behavior
Neuroscientists have uncovered a fascinating piece of the puzzle behind what makes us truly intelligent. While machines excel at repetitive tasks, humans and animals amaze with their ability to adapt, imagine, and generalize. What in the brain allows for this flexible thinking? A recent study in mice gives us clues by identifying specific brain cells responsible for tracking progress in complex behaviors—not just physical locations.
For decades, it has been known that certain brain cells, like place cells and grid cells, help animals navigate physical space. These cells create mental maps of the environment, guiding an animal or person through streets, rooms, or mazes. But what about navigating through a sequence of actions, such as cooking a new recipe or solving a fresh problem?
Researchers trained mice to perform a task in which they moved through a series of four goal locations to receive water rewards. The order of goals repeated in a loop, but to challenge them, the locations were moved. The mice instantly adjusted, understanding the sequence even in completely new situations. This wasn’t memory playing tricks; the mice were generalizing the structure of the task.
New study visualizes platinum doping on ultrathin 2D material with atomic precision
A popular 2D active material, molybdenum disulfide (MoS2), just got a platinum upgrade at an atomic level. A study led by researchers from the University of Vienna and Vienna University of Technology embedded individual platinum (Pt) atoms onto an ultrathin MoS2 monolayer and, for the first time, pinpointed their exact positions within the lattice with atomic precision.
The study, published in the journal Nano Letters, achieved this feat with an innovative approach that integrates targeted defect creation in the MoS2 monolayer, controlled platinum deposition, and a high-contrast computational microscopic imaging technique—ptychography.
The researchers believe that this new strategy for ultra-precise doping and mapping offers new pathways for understanding and engineering atomic-scale features in 2D systems.
