Storms and society: where things go wrong
February 26 — Tying images of a powerful ice storm to scenes of downed power lines and darkened homes does not take a great leap of imagination - but the science of their interrelationships is more complex.
Los Alamos licenses avian flu modeling and simulation software
October 12 — Santa Fe-based CIVA (The Company for Information Visualization and Analysis) signed an agreement to license Los Alamos National Laboratory's epidemiological modeling and simulation system, called EpiCast.
Seeing the unseen universe
July 31 — A new method for incorporating astronomical observational data into computer simulations promises to be a significant advance in enabling future cosmological surveys aimed at understanding dark energy and dark matter.
Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic
April 3 — Using supercomputers to respond to a potential national health emergency, scientists have developed a simulation model that makes stark predictions about the possible future course of an avian influenza pandemic, given today’s environment of world-wide connectivity.
Optical fibers and a theory of things that go bump in the light
September 14 — University of California scientists working at Los Alamos National Laboratory have developed a theory describing light pulse dynamics in optical fibers that explains how an interplay of noise, line imperfections and pulse collisions lead to the deterioration of information in optical fiber lines. The theory will help to enhance the performance necessary for high-speed optical communication systems like video on demand and ultra-broadband Internet, and the research has helped establish a new field of inquiry -- the statistical physics of optical communications.
Mapping the Evolution of a Virus
July 16 — A University of California scientist working at Los Alamos National Laboratory with collaborators from the University of Cambridge (England) and the World Health Organization National Influenza Center at Erasmus Medical Center, (Rotterdam, Netherlands) have developed a computer modeling method for mapping the evolution of the influenza virus. The method could soon help medical researchers worldwide develop a better understanding of certain mutations in influenza and other viruses that allow diseases to dodge the human immune system.
The Space Simulator - Modeling the universe on a budget
June 22 — For the past several years, a team of University of California astrophysicists working at Los Alamos National Laboratory have been using a cluster of roughly 300 computer processors to model some of the most intriguing aspects of the Universe. Called the Space Simulator, this de facto supercomputer has not only proven itself to be one of the fastest supercomputers in the world, but has also demonstrated that modeling and simulation of complex phenomena, from supernovae to cosmology, can be done on a fairly economical basis.
Scientists model the dynamics of DNA transcription
May 18 — In a collaboration with colleagues at Harvard Medical School, University of California researchers working at Los Alamos National Laboratory have developed a model and diagnostic tools to simulate the dynamics of DNA.
Scientists model disease outbreaks in urban social networks
May 13 — University of California researchers working at Los Alamos National Laboratory with colleagues at the University of Maryland and Rensselaer Polytechnic Institute have developed a method for modeling disease outbreaks in realistic urban social networks.
Scientists explore complexities of sea ice from high desert venue
May 10 — For nearly a decade, University of California researchers working at Los Alamos National Laboratory have been upgrading and fine-tuning a sea ice modeling program created at the Laboratory.
Researchers untangle complex network systems
May 5 — By exploring the tangled nature of complex network systems, researchers at Los Alamos National Laboratory and the University of Houston may have found a way to help scientists and engineers better understand dynamic processes on complex networks, such as the spread of infectious diseases, cascading massive electrical power failures, sources of vehicle traffic congestion on metropolitan roadways and information flow on the Internet.

NIH chooses Los Alamos to model urban epidemics
May 4 — An emergency room physician sees a patient with a high fever and a trace of a rash and admits her to the hospital. The next morning, three more patients with similar symptoms come in, then more until lab tests confirm the initial hunch: an outbreak of smallpox has begun. How to keep the outbreak from becoming an epidemic, and recommending the best responses to public health officials, could be revealed through computer simulations under development at the University of California's Los Alamos National Laboratory.
New Supernova models take on third dimension
June 4 — Astrophysicists from Los Alamos National Laboratory, New Mexico, have created the first 3-D computer simulations of the spectacular explosion that marks the death of a massive star. Presented to the American Astronomical Society meeting in Albuquerque, N.M., today, the research by Michael Warren and Chris Fryer eliminates some of the doubts about earlier 2-D modeling and paves the way for rapid advances on other, more exotic questions about supernovae.
Scientists protect quantum information in a noiseless subsystem
September 14 — Theorists at the Department of Energy's Los Alamos National Laboratory, in collaboration with an experimental team at the Massachusetts Institute of Technology, have realized a general and efficient method for protecting quantum information against noise. The demonstration paves the way for the development of novel means for storing delicate quantum information and should, in turn, further the evolution of quantum computers. Quantum computers promise greatly increased computational speeds useful for performing critical mathematical tasks, such as database searching and number factoring, and for simulating complex quantum systems.
Predicting El Niño: Lab researcher has some answers, more questions
January 17 — The Spanish term El Nino has been used for centuries by South American fishermen to describe the annual occurrence of warm, southward-flowing oceanic current waters off the coast of Ecuador and Peru around Christmas. El Niño, or the child, specifically refers to the Christ child.
Los Alamos scientists make seven bit quantum leap
March 22 — Scientists at the Department of Energy's Los Alamos National Laboratory have made yet another experimental leap forward in the quest for a functional quantum computer capable of solving large mathematical problems or cracking secret codes faster than today's fastest supercomputers.
