The Early Career Research Program provides financial support that is foundational to early career investigators, enabling them to define and direct independent research in areas important to Department of Energy (DOE) missions. The Early Career Award Winner series provides awardees with an opportunity to explain the results of their research in their own words.
As we approach the exascale computing era, performance and power usage are increasingly being determined by two factors. How quickly and how efficiently can we move data between the main memory, processors, accelerators, compute nodes, and disks?
To keep millions of compute cores active, we must feed them with data fast enough. That requires mitigating the bottleneck associated with data movement. This project set out to investigate three complementary approaches to reducing data movement in high-performance computing.
Read more about how Peter Lindstrom used his Early Career award to develop tools for high performance computing.

Copper oxides (cuprates) are materials that act as superconductors, conducting electricity with no resistance or loss. For the first time, a team at DOE’s SLAC National Laboratory and Stanford University has been able to track the way electrons pair up and condense as a cuprate transitions from its normal state to a superconducting state. This advance brings us closer to developing room-temperature superconductors. |
Scientists at the University of Massachusetts at Amherst and DOE’s Lawrence Berkeley National Laboratory (Berkeley Lab) recently overcame a major hurdle in robotics. They created robots that can work without any electrical input. The robots use chemistry to act like tiny submarines. They dive below the surface to retrieve precious chemicals and then resurface to deliver chemicals “ashore” without needing to recharge. |

DOE’s Center for Nanoscale Materials (a user facility at Argonne National Laboratory) has an ultrafast electron microscope, the first of its kind at a national user facility. The tool combines a modified transmission electron microscope with an ultrafast laser system to reveal small details with potentially big impacts. |
Engineers at the University of Illinois Chicago have built a cost-effective artificial leaf that can capture carbon dioxide at rates 100 times better than current systems. This artificial leaf can capture carbon dioxide from diluted sources, like gas produced by coal-fired power plants. It then can release it for use as fuel and other materials. |

Microbes play an important role in climate because they release carbon dioxide into the atmosphere when they eat. But it’s challenging to predict the size of that effect and how global warming will influence carbon dioxide emissions from these microbes. Researchers at Duke University showed that measuring certain features —like size and shape—allows them to reliably predict how microbes’ respiration will change as temperatures rise. The findings create a new source of information on the pace of climate change. |

Reshaping the World of Research Through Remote Experimentation
|
|
In the spring of 2020, national user research facilities shut down most operations due to the COVID-19 pandemic. They closed their doors to thousands of visiting scientists and brought research to a grinding halt. To figure out how to restart the facilities even if the scientists couldn’t access them in person, seven of the user facilities (five light sources and two neutron sources) formed a Remote Access Working Group. Since then, the facilities have developed environments in which scientists can run research remotely. Learn more about how these facilities changed their operations and what they’ve learned from the process. |

Prefer to hear your science news rather than read it? Check out podcasts from the Department and our national laboratories.
DOE puts out Direct Current, a podcast covering work across the entire department. Right now, they’re running a series called “People Powered” that focuses on clean energy careers and the people in them.
Oak Ridge National Laboratory produces The Sound of Science, which looks at a variety of research at the lab, including fusion, ecology, and quantum science. Argonne Voices from Argonne National Laboratory captures the stories of people behind the lab’s history. A Day in the Half Life from Berkeley Lab discusses everything from energy storage to dark energy. Pacific Northwest National Laboratory’s SciVIBE shares stories of the latest scientific discoveries from their lab. The Joint Genome Institute has two podcasts – Genome Insider and the Natural Prodcast – that highlight the latest in genomics research and share conversations with the researchers. Let’s Talk Exascale from the Exascale Computing Project goes behind the scenes to chat with the people bringing exascale to fruition.
