Divvying up fair share of carbon emissions
“Most of the world’s emissions come disproportionately from the wealthy citizens of the world, irrespective of their nationality,” says physicist Shoibal Chakravarty, noting that many emissions come from lifestyles that involve airplane flights, car use and the heating and cooling of large homes. “We estimate that in 2008, half of the world’s emissions came from just 700 million people.”

Portable device could deter dirty bomb attacks
The simple, portable device identifies materials through their characteristic energy signals. The three detectors are housed in a thermos-sized container that is connected to a laptop computer. The device issues a signal turning the laptop display bright red when nuclear material of interest is identified. (Credit: Denise Applewhite)

Say cheese! Scrambled light’s super-crisp shots
PRINCETON (US)—In photography, there are always trade-offs—zoom in for detail or go wide to capture the scene. An imaging method developed by Princeton University researchers could lead to lenses that reveal all parts of a panorama at once in high detail. The technique is designed to enhance resolution using normal light, allowing scientists to build microscopes and devices capable of so-called super-resolution. (more…)

Putting on the squeeze to ‘freeze’ water
PRINCETON (US)—Think there’s only one way to freeze water? Think again. Researchers may be able to “freeze” water into a solid, not by cooling it, but by confining it to narrow spaces less than one-millionth of a millimeter wide. (more…)

Quantum ‘dance’ could revolutionize computing
PRINCETON (US)—For years scientists have suspected that atoms placed in certain configurations would trigger electrons to perform a quantum dance of sorts. Now an international team of scientists has observed swarms of electrons spinning in a synchronized quantum dance within a new material. They are hopeful the discovery could be harnessed to transform computing and electronics. (more…)
