Communicating about science is a challenge. Bridging the gap between conversations with colleagues immersed in the language of the laboratory and audiences ranging from educated and curious to uninterested or even distrustful can be daunting. Add to that the potential consequences of miscommunication—particularly in high-stakes fields like nuclear materials management and nonproliferation, where political, safety, and security issues exacerbate the task—and some scientists might be tempted to run from the microphone. But scientists at the Institute for Nuclear Materials Management recently hosted two sessions on why it's important to communicate, and tips for making it easier.

A recent measurement exploring the structure of magnesium-40 has shown a surprising change in the structure relative to expectations. This unanticipated change could be pointing to physics missing from our theories, such as the effects of weak binding between particles.
Technology to measure the flow of subatomic particles known as antineutrinos from nuclear reactors could allow continuous remote monitoring designed to detect fueling changes that might indicate the diversion of nuclear materials. The monitoring could be done from outside the reactor vessel, and the technology may be sensitive enough to detect substitution of a single fuel assembly.

Nuclear power plants can withstand most inclement weather and do not emit harmful greenhouse gases. However, trafficking of the nuclear materials to furnish them with fuel remains a serious issue as security technology continues to be developed. Two physicists conducted research to enhance global nuclear security by improving radiation detectors. According to them, improving radiation detectors requires the identification of better sensor materials and the development of smarter algorithms to process detector signals. They discuss their work in this week’s Journal of Applied Physics.

Jefferson Sciences Associates has announced the award of nine graduate fellowships to doctoral students for the 2019-2020 academic year.
If you chart the stability of atomic cores (nuclei), the trend is that adding more protons and neutrons makes the atom less stable. However, there’s an island of stability that bucks this trend. If scientists can provide an easier way of producing elements predicted to be on that island of stability, they can fine-tune today’s nuclear models. Such elements were difficult to produce, until a team built an apparatus that efficiently produces superheavy elements by transferring multiple nucleons (either protons or neutrons).

But the answers to why medical implants fail and what we can do about it may come from an unlikely source — the nuclear fuel cycle. Researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory have discovered that the same factors link the corrosion of nuclear waste forms — the packages scientists build to secure waste for millions of years — to corrosive conditions within the body that may cause implant failure.
Accelerator physicists have demonstrated a groundbreaking technique using bunches of electrons to keep beams of particles cool at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy Office of Science user facility for nuclear physics research at Brookhaven National Laboratory. This “bunched-beam” electron cooling technique will enable higher particle collision rates at RHIC, where scientists study the collision debris to learn about the building blocks of matter as they existed just after the Big Bang.
