Nano-optic endoscope sees deep into tissue at high resolution

The diagnosis of diseases based in internal organs often relies on biopsy samples collected from affected regions. But collecting such samples is highly error-prone due to the inability of current endoscopic imaging techniques ...

Exposed water ice detected on comet's surface

Using the high-resolution science camera on board ESA's Rosetta spacecraft, scientists have identified more than a hundred patches of water ice a few metres in size on the surface of Comet 67P/Churyumov-Gerasimenko.

Ghost imaging speeds up super-resolution microscopy

Researchers have used advanced imaging approaches to achieve super-resolution microscopy at unprecedented speeds. The new method should make it possible to capture the details of processes occurring in living cells at speeds ...

Blurry imaging limits clarified thanks to information technology

Although we're told a picture speaks a thousand words, that cliché seriously underestimates the value of a good image. Our understanding of how the world works is simplified by our ability to turn data into images. Imaging ...

Comet's collapsing cliffs and bouncing boulders

Scientists analyzing the treasure trove of images taken by ESA's Rosetta mission have turned up more evidence for curious bouncing boulders and dramatic cliff collapses.

Miniaturizing medical imaging, sensing technology

Scientists in Christine Hendon's and Michal Lipson's research groups at Columbia University, New York, have used a microchip to map the back of the eye for disease diagnosis.
