Evolutionary battleground: Plants vs. microbes

DOE/US Department of Energy

Gazing out on a freshwater pond, you may see tiny green plants with oval shaped leaves floating in clusters. In overgrown ponds, these plants coat the water’s surface. These plants – called duckweed or water lentils – can grow so fast that they can double their numbers in just one to two days. But what you can’t see in that pond is the evolutionary battle between the plants and microbes trying to invade them.

Ice-cold plasma electron beams prepare to power future hard X-ray laser beams

DOE/US Department of Energy

Scientists have developed a blueprint for producing ultrabright and ultrashort pulses of electron beams for the next generation of particle accelerators, plasma wakefield accelerators (PWFA). This could enable new scientific tools such as X-ray free-electron-lasers (XFELs) that can see matter at smaller scales and faster speeds than now possible. It could also lead to compact accelerators.

US Department of Energy awards $138 million to 91 early career scientists

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) today announced the selection of 91 early career scientists from across the country who will receive a combined $138 million in funding for research covering a wide range of topics including artificial intelligence, fusion energy, and quantum. These awards are critical to the Biden-Harris Administration’s efforts to develop the next generation of STEM leaders to solidify America’s role as the driver of science and innovation around the world.

Laser-sharp look at spinning electrons sets the stage for new physics discoveries

DOE/US Department of Energy

Spin is an intrinsic property of the electron. When electrons spin in the same direction at a given time, the quantity is called polarization. Understanding polarization helps examine the structure of nuclei of heavy elements. Now, nuclear physicists have measured the polarization of an electron beam more precisely than ever before. The result will aid in ongoing studies to refine and expand the Standard Model of particle physics.

DOE/US Department of Energy
Grant and Award Announcement

The U.S. Department of Energy (DOE) today announced $65 million in funding in quantum computing for 10 projects, comprising a total of 38 separate awards.

For solar fuels, more surface area on photoelectrodes makes a difference

DOE/US Department of Energy

Scientists have identified a new way to improve the process for using light to make a liquid fuel from carbon dioxide. Research shows that three-dimensional silicon scaffolds on photoelectrodes improve the yield of the desired products of chemical reactions, even converting carbon dioxide to methanol.

DOE, ORNL announce opportunity to define future of high-performance computing

DOE/US Department of Energy
Grant and Award Announcement

The Department of Energy’s (DOE) Office of Science today announced a new research and development opportunity led by Oak Ridge National Laboratory (ORNL) to advance technologies and drive new capabilities for future supercomputers.

Department of Energy announces $68 million in funding for artificial intelligence for scientific research

DOE/US Department of Energy
Grant and Award Announcement

The use of Artificial Intelligence (AI) in scientific research is a top priority at the Department of Energy (DOE), which today announced $68 million in funding for 11 multi-institution projects, comprising 43 awards.

Department of Energy announces $118 million for Energy Frontier Research Centers

DOE/US Department of Energy
Grant and Award Announcement

Ten Energy Frontier Research Centers (EFRCs) designed to bring together world-class teams of scientists for groundbreaking fundamental research have been funded in nine states by the U.S. Department of Energy (DOE).

Detecting the “kick” from a single nuclear decay

DOE/US Department of Energy

Scientists have for the first time mechanically detected individual nuclear decays occurring in a microparticle. The research used a new technique. Rather than detecting the radiation emitted by the nuclei, the researchers detected the occurrence of decay by measuring the tiny “kick” to the entire microparticle that contained the decaying nucleus as this radiation escaped.
