DNA Provides Clean Air

August 28, 2013 11:26 am | Award Winners

One of the most overlooked threats to human health is poor indoor air quality. Various air pollutants exist indoors, including biological pollutants, secondhand smoke, combustion pollutants and other chemicals, and can pool in spaces with inadequate ventilation. Determining the source of pollution is often the first step in improving air quality. Lawrence Livermore National Laboratory’s DNA TRAX, a safe simulant material made with non-biological DNA, can track and quantify indoor airflow.

Laser fusion experiment yield record energy

August 27, 2013 8:25 am | News | Comments

On Aug.13, 2013, Lawrence Livermore National Laboratory's National Ignition Facility (NIF) focused all 192 of its ultrapowerful laser beams on a tiny deuterium-tritium filled capsule. In the nanoseconds that followed, the capsule imploded and released a neutron yield of nearly 3x1015, or approximately 8,000 joules of neutron energy, approximately three times NIF's previous neutron yield record for cryogenic implosions.
