It's not quite a quantum internet — yet. But researchers at Los Alamos National Laboratory in New Mexico have developed a new, ultra-secure computer network that is capable of transmitting data that has been encrypted by quantum physics, including video files. The network, which currently consists of a main server and three client machines, has been running continuously in Los Alamos for the past two and a half years, the researchers reported in a paper released earlier this month. During that time, they have also successfully tested sending critical information used by power companies on the status of the electrical grid. Eventually they hope to use it to test offline quantum communication capabilities on smartphones and tablets.

2011 was a year of global tumult, marked by widespread social and political uprisings, economic crises, and a great deal more. We saw the fall of multiple dictators, welcomed a new country (South Sudan), witnessed our planet's population grow to 7 billion, and watched in horror as Japan was struck by a devastating earthquake, a tsunami, and a nuclear disaster. From the Arab Spring to Los Indignados to Occupy Wall Street, citizens around the world took to the streets in massive numbers, protesting against governments and financial institutions, risking arrest, injury, and in some cases their lives. Collected here is Part 2 of a three-part photo summary of the last year, covering 2011's middle months. Be sure to also see Part 1, and Part 3 of this series totaling 120 images in all. [40 photos]

Rescue swimmers Eddie Mendez (left) and Will Green had found Ostrander in the surf, after the boy was underwater for more than 20 minutes. Ostrander was hospitalized and placed in a medically induced coma for a time, but has since returned home and started the 7th grade. His recovery is still in progress, as he continues to undergo speech and physical therapy. (AP Photo/Damian Mulinix/Chinook Observer)

The Las Conchas wildfire in New Mexico spread dangerously close to the Los Alamos National Laboratory this week, causing the evacuation of the town and the shutdown of the lab, which is the headquarters for US military research. The laboratory was created during World War II to develop the first atomic bomb for the Manhattan Project and houses highly sensitive materials. As a precaution, scientists are monitoring radioactivity in the air. The fire is the largest wildfire in the state's history, covering more than 100,000 acres.(Editor's Note: We will not post on Monday, July 4th, we'll see you again on Wednesday, July 6, 2011.) -Leanne Burden Seidel (34 photos total)
A vicious wildfire burns near the Los Alamos Laboratory in Los Alamos, N.M., on June 28, 2011. The Las Conchas fire spread through the mountains above the northern New Mexico town, driving thousands of people from their homes as officials at the government nuclear laboratory tried to dispel concerns about the safety of sensitive materials.

Re-Configurable EXASCALE Computing

Google Tech Talk February 15, 2011 Presented by Steven J Wallach, Convey Computer Corp. ABSTRACT HPC research is focused on achieving ExaFlop/ExaOP performance by 2020. Unlike reaching a PetaFlop, the general consensus is that vastly new programming paradigms, hardware architectures, and interconnects will be needed (as well as new power plants). This presentation will be focused on increasing uni-processor performance and the roles played by application specific heterogeneous computing and compilers in evolving processor architecture. Steven J Wallach is a founder of Convey Computer Corporation and is an adviser to venture capital firms CenterPoint Ventures, Sevin-Rosen and InterWest Partners. Previously, he served as vice president of technology for Chiaro Networks Ltd., and as co-founder, chief technology officer and senior vice president of development of Convex Computer Corporation. After Hewlett-Packard Co. bought Convex, Wallach became chief technology officer of HP's Enterprise Systems Group. Wallach served as a consultant to the US Department of Energy's Advanced Simulation and Computing Program at Los Alamos National Laboratory from 1998 to 2007. He was also a visiting professor at Rice University in 1998 and 1999, and was manager of advanced development for Data General Corporation. His efforts on the MV/8000 are chronicled in Tracy Kidder's Pulitzer Prize winning book, "The Soul of a New Machine." Wallach, who has 34 patents, is a member of the National <b>...</b>
