Gamma-ray laser moves a step closer to reality

A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium.

Using electronics to solve common biological problems

What do an electrical engineer, an organic chemist, a materials scientist and a cell biologist all have in common? They invent and improve applications at the interface of biology and electronics.

4-D imaging with liquid crystal microlenses

Most images captured by a camera lens are flat and two dimensional. Increasingly, 3-D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4-D imaging, which adds information ...

High-speed microscope illuminates biology at the speed of life

The Columbia team behind the revolutionary 3-D SCAPE microscope announces today a new version of this high-speed imaging technology. In collaboration with scientists from around the world, they used SCAPE 2.0 to reveal previously ...

Machine learning increases resolution of eye imaging technology

Biomedical engineers at Duke University have devised a method for increasing the resolution of optical coherence tomography (OCT) down to a single micrometer in all directions, even in a living patient. The new technique, ...

Lessons of conventional imaging let scientists see around corners

Along with flying and invisibility, high on the list of every child's aspirational superpowers is the ability to see through or around walls or other visual obstacles. That capability is now a big step closer to reality as ...
