New imaging method reveals nanoscale details about DNA

Researchers have developed a new enhanced DNA imaging technique that can probe the structure of individual DNA strands at the nanoscale. Since DNA is at the root of many disease processes, the technique could help scientists ...

High-precision magnetic field sensing

Scientists have developed a highly sensitive sensor to detect tiny changes in strong magnetic fields. The sensor may find widespread use in medicine and other areas.

The trillion-frame-per-second camera

When a crystal lattice is excited by a laser pulse, waves of jostling atoms can travel through the material at close to one sixth the speed of light, or approximately 28,000 miles/second. Scientists now have a new tool to ...

Nanoimaging in 3-D

(PhysOrg.com) -- As technology shrinks ever smaller, interest in objects and devices on the nanoscale becomes more apparent. However, visualizing these objects in three dimensions comes with special challenges. Alexander ...

Helium raises resolution of whole cell imaging

The ability to obtain an accurate three-dimensional image of an intact cell is critical for unraveling the mysteries of cellular structure and function. However, for many years, tiny structures buried deep inside cells have ...
