The Dirt Whisperer

Say you’re a civil engineer, and you’re looking for a good place to put a bridge. Wouldn’t it be nice to be able to ask the ground how stable it is before you start digging, like some sort of dirt whisperer?  Or how close an older bridge is to failing, after erosion has affected the…

Anarchy in the Pathway?

We’d be nothing without our proteins – they transport signals around cells , and so have a hand in regulating every single process in our bodies.  Scientists know that one way proteins accomplish this transport is to fold themselves into a specific shape that corresponds with a particular molecule.  Picture a lock that only opens…

How Magnets Work (It’s Complicated)

Occasionally, when looking for scientific issues to write about, I will survey my friends to see whether they have any “fundamental science” questions that I could explore. When someone recently suggested that I find out how magnets work, I thought it would be easy. I was wrong. First of all, I learned that there are…

Into The Void: Boosting LED Energy Efficiency

LEDs are already vaunted as an energy-efficient technology for lighting, but new research shows that their efficiency can be increased by a factor of two. A paper describing the work shows that the secret is to decrease the number of defects in the gallium nitride (GaN) films used to create LEDs by incorporating cleverly placed…

Voiding Defects: New Technique Makes LED Lighting More Efficient

Light-emitting diodes (LEDs) are an increasingly popular technology for use in energy-efficient lighting. Researchers from North Carolina State University have now developed a new technique that reduces defects in the gallium nitride (GaN) films used to create LEDs, making them more efficient.

Building a Better Sun-Trap

How does the saying go? Build a better solar cell and the world will beat a path to your efficiently temperature-controlled and environmentally friendly door? Okay, maybe that’s not exactly the saying, but you’ve got to admit that the idea of cheaper, more efficient solar technology is at least as compelling today as the idea…

Technique Allows Researchers to Examine How Materials Bond at the Atomic Level

An approach pioneered by researchers at North Carolina State University gives scientists new insight into the way silicon bonds with other materials at the atomic level. This technique could lead to improved understanding of and control over bond formation at the atomic level, and opportunities for the creation of new devices and more efficient microchips.…
