Green algae express genes more like bacteria than previously thought
DOE/US Department of Energy
To fulfill its function, a gene must first be "transcribed" into an RNA molecule that is in turn "translated" into a protein that controls cells. Bacteria use a type of transcription that scientists previously believed was extremely rare in eukaryotes--animals, plants, fungi, and green algae. A new study finds that hundreds of proteins in many species of green algae use the same type of transcription as bacteria.

For Earth systems scientists, every day is Earth Day
DOE/US Department of Energy
Research on Earth's systems can help scientists better understand our planet's past and future. The Department of Energy's Office of Science supports work to gather observations, improve models, and feed them into computer simulations.

Dan Melconian: Then and now / 2011 Early Career Award Winner
DOE/US Department of Energy
Dan Melconian is developing new techniques and new equipment to test our current theory of electroweak interactions. Comparison of these precision measurements to theoretical predictions will either confirm the Standard Model to a higher degree or point to a New Standard Model.

New approach helps determine how microbial community composition is driven by selection and cha
DOE/US Department of Energy
Quantifying the relative importance of natural selection, migration, and random shifts to a species is a major challenge in ecology research, especially for microbes. This study develops an approach named iCAMP that is based on the concept that different processes can govern different groups of species in a diverse community. Applied to grassland microbial communities, iCAMP revealed that environmental changes altered the relative importance of the ecological processes.

Finding gene neighbors leads to new protein functions
DOE/US Department of Energy
As scientists have developed new technologies for gene sequencing, the availability of sequenced genes has grown exponentially, but scientists' ability to decipher the functions encoded in these sequences has not kept pace. In this study, researchers working with green algae discovered that physically clustered genes in eukaryotic genomes can be maintained over hundreds of millions of years. This phenomenon can help predict function.

Department of Energy to provide $2 million for traineeship in isotope R&D and production
DOE/US Department of Energy
Today, the US Department of Energy (DOE) announced up to $2 million to establish a traineeship program to advance workforce development in the field of isotope production, processing, and associated research, with preference to minority serving institutions.

For better predictions, researchers evaluate E3SM tropical cyclone simulation
DOE/US Department of Energy
Infrastructure planning requires accurately predicting how tropical cyclones respond to environmental changes. To make those predictions, researchers use Earth system models. In this research, scientists analyzed tropical cyclones simulated by the Department of Energy's Energy Exascale Earth System Model (E3SM). They found that high resolution is critical to simulating tropical cyclones and their interactions with the ocean.

Department of Energy to provide $10 million for research on data reduction for science
DOE/US Department of Energy
Today, the U.S. Department of Energy (DOE) announced $10 million for foundational research to address the challenges of managing and processing the increasingly massive data sets produced by today's scientific instruments, facilities, and supercomputers in order to facilitate more efficient analysis.

Understanding the source of extremely small particles above the Amazon
DOE/US Department of Energy
The aerosol particles that serve as seeds for cloud formation are major drivers of global climate change. However, the sources and chemical processes behind the formation of these particles are unclear. Researchers have now found that carbon-based compounds from natural biological sources drive the formation of new particles. These sources play key roles in producing the large number of small particles in the atmosphere above the Amazon rainforest.
