Novel 3-D oral scanner helping dentists go digital

Traditionally, dentists have made dental impressions by having patients bite down on a moldable silicone material. Such impressions, however, can be messy and uncomfortable, and sometimes inaccurate.

Five years of stereo imaging for NASA's TWINS

(Phys.org) —Surrounding Earth is a dynamic region called the magnetosphere. The region is governed by magnetic and electric forces, incoming energy and material from the sun, and a vast zoo of waves and processes unlike ...

Abell 383: Getting a full picture of an elusive subject

(Phys.org)—Two teams of astronomers have used data from NASA's Chandra X-ray Observatory and other telescopes to map the distribution of dark matter in a galaxy cluster known as Abell 383, which is located about 2.3 billion ...

Peering into living cells—without dye nor fluophore

In the world of microscopy, this advance is almost comparable to the leap from photography to live television. Two young EPFL researchers, Yann Cotte and Fatih Toy, have designed a device that combines holographic microscopy ...

Three-photon microscopy improves biological imaging

(Phys.org)—Scientists may be a step closer to cracking one of the world's most compelling mysteries: the impossible complexity of the brain and its billions of neurons. Cornell researchers have demonstrated a new way of ...

Architecture of rod sensory cilium disrupted by mutation

Using a new technique called cryo-electron tomography, two research teams at Baylor College of Medicine have created a three-dimensional map that gives a better understanding of how the architecture of the rod sensory cilium ...

No evidence for 30-nm chromatin fibers in the mouse genome

Scientists in Canada and the United States have used three-dimensional imaging techniques to settle a long-standing debate about how DNA and structural proteins are packaged into chromatin fibres. The researchers, whose findings ...
