and functionality through discovery science and engineering. Nuclear and Particle Futures integrates nuclear experiments, theory, and simulation to understand and engineer complex nuclear phenomena. Science of Signatures (SoS) applies science and technology to intransigent problems of system identification and characterization in areas of global security, nuclear defense, energy, and health. Complex Natural and Engineered Systems (CNES) Weapons Systems (WS) Los Alamos operates three main user facilities: The Center for Integrated Nanotechnologies: The Center for Integrated Nanotechnologies is a DOE/Office of Science National User Facility operated jointly by Sandia and Los Alamos National Laboratories with facilities at both Laboratories. CINT is dedicated to establishing the scientific principles that govern the design, performance, and integration of nanoscale materials into microscale and macroscale systems and devices. Los Alamos Neutron Science Center (LANSCE): The Los Alamos Neutron Science Center is one of the world's most powerful linear accelerators. LANSCE provides the scientific community with intense sources of neutrons with the capability of performing experiments supporting civilian and national security research. This facility is sponsored by the Department of Energy, the National Nuclear Security Administration, Office of Science and Office of Nuclear Energy, Science and Technology. The National High Magnetic Field Laboratory (NHMFL), Pulsed Field Facility: The Pulsed Field Facility at Los Alamos National Laboratory in Los Alamos, New Mexico, is one of three campuses of the National High Magnetic Field Laboratory (NHMFL), the other two being at Florida State University, Tallahassee and the University of Florida. The Pulsed Field Facility at Los Alamos National Laboratory operates an international user program for research in high magnetic fields. As of 2017, the Los Alamos National Laboratory is using data and algorithms to possibly protect public health by tracking the growth of infectious diseases. Digital epidemiologists at the lab's Information Systems and Modeling group are using clinical surveillance data, Google search queries, census data, Wikipedia, and even tweets to create a system that could predict epidemics. The team is using data from Brazil as its model; Brazil was notably threatened by the Zika virus as it prepared to host the Summer Olympics in 2016. Laboratory management and operations Around LANL's 43-square-mile property are 2,000 dumpsites which have permanently contaminated the environment. It also contributed to thousands of dumpsites at 108 locations in 29 US states. Contract changes Continuing efforts to make the laboratory more efficient led the Department of Energy to open its contract with the University
