In the First-Person Science series, scientists describe how they made significant discoveries over years of research. Jacqueline Chen is a senior scientist at the Combustion Research Facility at Sandia National Laboratories.
Conducting extreme-scale computational science at some of the world’s largest computing facilities has been a wonderful ride.
My work over the last 25 years has focused on using leadership-class computers at the Department of Energy’s user facilities to model the flames that result from turbulent combustion. This is the combustion that happens in engines burning fuels such as natural gas, biofuels, or gasoline.
Read more of Jacqueline Chen’s story of how her research has evolved over time and expanded our understanding of the interactions in combustion.

Physicists use the earliest light in the cosmos, called the cosmic microwave background, to study astrophysics. Researchers at DOE SLAC National Accelerator Laboratory had been using it to find signs of early gravitational waves. They recently announced that they did not find those signs, which eliminates some possible models of cosmic inflation. Cosmic inflation is the idea that extremely early in the universe, the entire thing exploded in size.

An international team of physicists led by researchers at Indiana University has announced the world's most precise measurement of the neutron's lifetime. The neutron lifetime is important for the major role it plays in the Standard Model of Particle Physics. The researchers conducted the experiment at Los Alamos National Laboratory. |

In a unique field experiment, researchers at Northern Arizona University found that over 15 years of warmer climate conditions, microbes’ growth rate decreased. Growth decreased among all types of microbes, suggesting that that a loss of soil carbon may be responsible for the slowdown. |

Super strong and only an atom thick, graphene could be used in a variety of applications from microelectronics to clean energy storage. But it has major limits on how well it acts as a semiconductor, which is essential for microelectronics. Researchers at Princeton University and DOE’s Princeton Plasma Physics Laboratory have used low-temperature plasma to overcome that problem. |

Climate Science Social Media Campaign Kicks Off
|
|
|
From November 1 through 12, we're running a social media campaign highlighting climate science work supported by the DOE’s Office of Science. In addition to posts from our DOEScience Twitter account, several of our scientists will be tweeting about their research from their accounts. We’re also hosting an Instagram Live with our researchers (on the Department of Energy’s Instagram account) on November 5 from noon to 1 PM ET and a Twitter chat on November 10 from 1-2 PM ET. So be sure to follow along with the hashtag #DOEClimateScience!

Video: Rapid Research Response for Mitigating Post-Wildfire Effects

After the Caldor Fire erupted in California this past August, scientists from Berkeley Lab launched a research project to study how the fire would affect the mountain ecosystem. They looked at a number of factors, including streamflow, groundwater levels, water quality, and possible soil erosion leading to floods and debris flow. They mobilized to burn areas to collect samples of water, sediment, and ash. Check out this video from Berkeley Lab describing how they took action. |
