SFI Colloquium: What Social Computing Means to Emergency Management

Tuesday March 12 • 3:30 p.m. • Noyce Conference Room at the Santa Fe Institute, 1399 Hyde Park Road in Santa Fe.

Leysia Palen, University of Colorado, Boulder

Abstract: Growth in the capabilities of and access to social computing services brings new questions to bear on how large scale on-line interaction is studied, understood, and shaped.

In an area of research we call “crisis informatics,” I examine the use of social media in mass emergency contexts by extending methodological approaches and theoretical Read More

NIST’s prototype solid-state refrigerator uses quantum physics in the square chip mounted on the green circuit board to cool the much larger copper platform (in the middle of the photo) below standard cryogenic temperatures. Other objects can also be attached to the platform for cooling. Photo by Schmidt/NIST

NIST News:

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a solid-state refrigerator that uses quantum physics in micro- and nanostructures to cool a much larger object to extremely low temperatures.

What’s more, the prototype Read More

LANL News:

Sandia National Laboratories historian Rebecca Ullrich discusses Sandia’s transition from a Los Alamos division to an independent organization during a talk at 5:30 p.m., March 13 at the Bradbury Science Museum in Los Alamos. The talk is part of the Laboratory’s 70th anniversary lecture series.

Sandia Labs’ origins are in Los Alamos’ Z Division, the engineering assembly and test support functions of the Manhattan Project.

At the end of World War II, Z Division relocated Read More
