Nuclear charge distribution measurements may solve outstanding puzzle In particle physics

DOE/US Department of Energy

Researchers recently reviewed the current standard procedure to determine the nuclear weak distribution, which describes the distribution of active protons in a nucleus. The new analysis found significant differences with previous model-based determinations of the nuclear weak distribution. The results provide a partial explanation for a discrepancy between predictions from particle physics theory and experimental measurement of a fundamental quantity.

Quantum error correction moves beyond breakeven

DOE/US Department of Energy

Quantum systems decohere due to unwanted interactions with their environment. Correcting for the effects of decoherence is a major challenge for quantum information systems. Previous error correction methods have not kept up with decoherence. Now, researchers have enhanced the lifetime of quantum information past breakeven by more than twofold. This experiment establishes that there is no fundamental obstacle to significantly extending the lifetime of quantum information through active intervention.

Less rain in town, more rain on the farm: the effects of urbanization and irrigation on mid-Atlantic summer precipitation

DOE/US Department of Energy

Researchers investigated how large-scale urbanization and irrigation in the United States affect the three dominant types of summer precipitation in the mid-Atlantic region. They found that urbanization suppresses all three types of precipitation. Irrigation enhances non-convective and isolated deep convection precipitation, and its effects on mesoscale convective systems (MCS) depends on whether an MCS formed locally or remotely.

US Department of Energy releases plan to ensure free, immediate, and equitable access to federally funded research

DOE/US Department of Energy
Business Announcement

The U.S. Department of Energy (DOE) today released a plan to ensure the Department’s Federally funded research is more open and accessible to the public, researchers, and journalists as part of a broader effort by the Biden-Harris Administration to make government data more transparent. With 17 National Laboratories and scores of programs that fund university and private research, DOE directly supports thousands of research papers per year, and, when this plan goes into effect, those findings will be available immediately and at no cost.

New insights on the prevalence of drizzle in marine stratocumulus clouds

DOE/US Department of Energy

Detecting drizzle in its early stages in marine stratocumulus clouds is important for studying how water in clouds becomes rainfall. However, detecting the initial stages of drizzle is challenging for ground-based remote-sensing observations. Researchers developed a machine-learning-based approach using unique radar Doppler spectra observations to identify the early stage of drizzle drops. The results show that drizzle is more frequent than previously recognized.

Discovering evidence of superradience in the alpha decay of mirror nuclei

DOE/US Department of Energy

Nuclei can absorb energy, pushing the nuclei into excited states. When these states decay, the nuclei emit different particles. The interplay between these decay channels and the internal characteristics of the excited states gives rise to phenomena such as superradiance. In superradiance, a nucleus with high excitation energy has excited states so dense that neighboring excited states overlap. Scientists recently found evidence of the superradiance effect in the differences between decaying states in Oxygen-18 and Neon-18.

Host genetics play a significant role in the composition of switchgrass root microbiomes

DOE/US Department of Energy

A new study investigated the role of the genes in individual switchgrass plants in determining the composition of the bacterial communities associated with the plants’ roots. The results indicate that genes involved in host immunity, plant development, and hormone signaling have roles in how plants acquire their microbiome. The study may help to engineer or breed plant varieties that form stronger beneficial associations with their microbiomes.

Junjie Zhu : Then and Now / 2012 Early Career Award Winner

DOE/US Department of Energy

Supported by his Early Career Research Program award, physicist Junjie Zhu’s work at the CERN Large Hadron Collider led to the first-ever evidence of two rare but important physics processes. These interactions produce the particles responsible for nuclear decay.
