Neutrons used to study model vascular systems

In what may be the first use of neutron scattering to study complex bio-medical systems under dynamic conditions, Los Alamos researchers and collaborators mimicked blood flow by engineering a layer of human endothelial cells (the cells that cover the inner surface of blood vessels) and subjecting them to shear stress.

Simultaneously, the team used neutrons at the Lujan Neutron Scattering Center's Surface Profile Analysis Reflectometer (SPEAR) to understand changes in the cell's properties. (Full Story)

27 amazing images from the depths of scientific labs

As an image-driven person, I often find myself deeply lost and buried in the vast online libraries of universities and research centres. Scientists just love to show off all the big and shiny machinery they work on. (Full Story)

Best secret ski towns of North America

For years Los Alamos wasn’t just a secret ski town, it was a secret town, period. High on the hidden Pajarito Plateau of the Jemez Mountains, 35 miles northwest of Santa Fe, the Los Alamos National Laboratory was established here by the U.S. government at the height of World War II as a top-secret facility to develop the nuclear bomb. The lab and town that sprung up around it to house scientists wasn’t revealed to the public until 1950. (Full Story)
