    Perovskites power up the solar industry

    Tsutomu Miyasaka was on a mission to build a better solar cell. It was the early 2000s, and the Japanese scientist wanted to replace the delicate molecules that he was using to capture sunlight with a sturdier, more effective option.

    So when a student told him about an unfamiliar material with unusual properties, Miyasaka had to try it. The material was “very strange,” he says, but he...

    Nanoparticles in foods raise safety questions

    It seemed like a small thing when Paul Westerhoff’s 8-year-old son appeared, with his tongue and lips coated bright white. The boy had just polished off a giant Gobstopper, a confectionery made of sugary, melt-in-the-mouth layers. Curious about the white coating, Westerhoff, an environmental engineer, pored over the jawbreaker’s contents and discovered just how incredibly small the matter was...

    Tom’s Top 10 interpretations of quantum mechanics

    Dozens of interpretations of quantum mechanics have been developed over the years. Most of them attempt to address what happens when an observation or measurement is made on a quantum system. The mathematical formula known as the wave function (or state vector) describing the state of a system gets reset when a measurement is made, and the multiple possibilities that the math describes appear...

    Gell-Mann, Hartle spin a quantum narrative about reality

    Second of two parts (read part 1)

    Science is a map of nature. It helps you navigate your way through the world. And like all good maps, it provides just the essential information, not too much detail. (In technical terms, maps are “coarse-grained.”)

    But science is more than a map. Science is also story about nature. And as a story, science also leaves details out, the way some...

    Brain patterns of haunting memories

    Please welcome this month’s Scicurious Guest Writer, Emilie Reas! 

    My first trip to a haunted house is as vivid today as when I was 5 years old. As I made my way past a taunting witch and a rattling skeleton, my eyes fell upon a blood-soaked zombie. My heart raced, my throat swelled, and the tears began to flow. Even now, as a mature (ahem) adult, the ghosts and goblins don’t faze me....

    The Anorexic Brain

    In a spacious hotel room not far from the beach in La Jolla, Calif., Kelsey Heenan gripped her fiancé’s hand. Heenan, a 20-year-old anorexic woman, couldn’t believe what she was hearing. Walter Kaye, director of the eating disorders program at the University of California, San Diego, was telling a handful of rapt patients and their family members what the latest brain imaging research...

    When Networks Network

    Half a dozen times each night, your slumbering body performs a remarkable feat of coordination.

    During the deepest throes of sleep, the body’s support systems run on their own timetables. Nerve cells hum along in your brain, their chitchat generating slow waves that signal sleep’s nether stages. Yet, like buses and trains with overlapping routes but...

    Space Eats

    Even an Iron Chef couldn’t master what a food-centric cadre of NASA scientists do every day: Devise tasty, healthy meals for astronauts to take into low-Earth orbit and beyond — perhaps even to Mars.

    Feeding people in space is harder than it sounds. Meals have to contain enough nutrients to keep the human body functioning in near-zero gravity. Slicing, dicing and stir-...

    Fertile Frontiers

    The solar system’s spotted bully and its ringed sidekick are holding some tantalizing treasures in their gravitational clutches. Circling Jupiter and Saturn are more than a hundred moons, including some of the most promising hosts for extraterrestrial life in the solar system.

    But not every one of these moons is an equal opportunity extraterrestrial petri dish....

    What's Cookin'

    At minibar, a six-seat restaurant within the Café Atlántico in Washington, D.C., many menu items sound familiar: Philly cheese steak, conch fritters, corn on the cob, and mojitos. But the mojito doesn't come in a glass. It is served as a bite-sized sphere on a spoon. Calcium chloride is mixed with the traditional rum, lime, mint, and sugar. A dollop of this concoction is dropped into a bath...
