Finding mass graves from on high
Aerial surveys that scan the ground at many wavelengths, some visible and some not, may offer a way to quickly and easily detect mass grave sites.

Diamond detectors
The quantum states of single diamond impurities work as magnetic sensors that could enable nuclear magnetic resonance to detect single atoms.

Water-Hogging Electric Vehicles
Electric cars may save on gasoline, but some can place an indirect drain on other resources.

Nanocrystal
Researchers have used DNA as Velcro to create the first materials that spontaneously assemble into regular 3-D patterns.
- Tech
Smells like DNA
By reshuffling the chemical letters of the genetic code, scientists have made short strands of DNA that can distinguish several different smells, such as explosives and food preservatives.
