What Wind Farms Can Learn from Football Teams

Winning football teams are composed of members that work well together, capitalizing on each other’s strengths and compensating for each other’s weaknesses. But that mindset can be applied in a lot of different circumstances—it turns out that wind farms can benefit from this strategy, too. New research shows that by incorporating cooperation, wind farms could output as much as ten times more power per area than they do now...and that would be a win for all of us. The research will be published in an upcoming issue of the American Physical Society’s journal Physical Review Fluids .

Numbers in the News: Can I Really Have a Set of Artificial Gills?

According to a story in CNN, you may soon be able to slip into a set of artificial gills , and take to the water without having to haul along a pressurized tank of the atmosphere.

From the Military to Mars: 3D Printing with Whatever you've Got

Prosthetics, tools, homes, cars—the possibilities of 3D printing are vast and exciting, even more so as researchers develop ways to use on-site materials in remote locations for printing.

Becoming the Noise, Part II: Putting Humans into the Physics Equation

Read part I of this story here . When I set out for Orfield Labs, I expected the anechoic chamber to capture my full attention. After all, so many people come to experience the quietness that the lab had to start charging for tours, to compensate for lost productivity. As I talked with founder and president Steve Orfield about the evolution of his career and his lab, though, I started to appreciate that the chamber is a tool. And eventually I concluded that, like all tools, the true value lies in what it can do in the hands of an artisan.

Numbers in the News: How Big is that Lake on Mars?

In case you missed it, last month NASA announced the discovery of what looks like liquid water on Mar s: a 20-kilometer (12.4-mile) wide lake hiding under 1.5 km (~1 mile) of ice. A lake 20 kilometers across sounds like a lot of water, even if it is deep under the ice. Why did it take so long to find if it is such a large feature? Let’s put this into perspective and compare the size of the lake on Mars to the size of a dot on a basketball. The comparison might surprise you.

Are Gravitational Waves the Key to Nailing Down the Universe's Expansion Rate?

Just over a century ago, Einstein sat scratching his head over his own theory of general relativity. Although the equations seemed to fit all of astronomers' observations of the universe to date, there was one little detail he couldn’t seem to shake: the universe ought to be contracting over time, scrunched together by the pull of gravity.

NASA is About to Launch a Sun-Skimming Solar Probe

Imagine yourself standing comfortably in front of a warm, cozy fire. Suddenly, you start to feel just a little too toasty, so you take a few steps away. But wait—now that you’re farther from the fire, it’s even hotter! Huh?

Manipulating Light May Hold the Key to Quantum Computing

It’s one of technology’s hottest (and most elusive) goals for the 21st century: quantum computing. You’ve probably heard talk of these powerful machines, which have the potential to completely transform our computing capabilities and upend modern data security. Although the foundations of this technology have already been laid down in research labs, we haven’t yet been able to develop quantum computers that can overtake their classical counterparts. However, some recent research from a group at the University of Maryland and NIST’s Joint Quantum Institute may bring us one step closer.

Numbers in the News: Sand, Sand Everywhere

This past Sunday NPR’s Weekend Edition interviewed Vince Beiser about his new book The World in a Grain . During the interview , Beiser made a mind-boggling claim. If you take all the sand used commercially every year, all 50 billion tons of it, you would have enough sand to cover the state of California. To which Californians might ask: “Well, how deep are we talking?”

"Looking Cool" with an Infrared Invisibility Cloak

Who among us hasn’t dreamed of owning an invisibility cloak? Now, a team at the University of Wisconsin-Madison thinks they have one figured out . There's a catch, though: It only works for infrared light. Although infrared is already invisible to human eyes, it’s extremely useful in security and defense, making this an exciting development.
