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…)

Engineered silicone reborn as medical cure
UC IRVINE (US)—What’s the connection between solar cells and urinary tract disorders? Research by Frank Shi. His team at the University of California, Irvine developed a specially formulated silicone for use in optical electronics. New findings suggest the substance could play a double role, revolutionizing treatment of urinary tract diseases. (more…)

‘Dark cells’ of living retina imaged for first time
U. ROCHESTER (US)—In a quest to figure out why one of the most prevalent eye diseases actually happens, researchers have captured the first-ever images of “dark cells” in a living retina. The new technique for seeing this nearly invisible layer of cells could help doctors identify the onset of many diseases of the eye, including macular degeneration, long before a patient notices symptoms.

The photon force is with us—and it’s driving our nanomachines
YALE (US)—Science fiction writers have long envisioned sailing a spacecraft by the optical force of the sun’s light. But, the forces of sunlight are too weak to fill even the oversized sails that have been tried. Now a team led by researchers at the Yale School of Engineering & Applied Science has shown that the force of light indeed can be harnessed to drive machines—when the process is scaled to nano-proportions.
