Researchers provide experimental data about how radiation travels through dense plasmas. Their data will improve plasma models, which allow scientists to better understand the evolution of stars and may aid in the realization of controlled nuclear fusion as an alternative energy source.

A new study has measured how long it takes for several kinds of exotic nuclei to decay. The paper marks the first experimental result from the Facility for Rare Isotope Beams. It is just a small taste of what's to come at the facility, which will become 400 times more powerful over the coming years. Scientists used the facility to better understand nuclei, the collection of protons and neutrons found at the heart of atoms. Understanding these basic building blocks allows scientists to refine their best models and has applications in medicine, national security, and industry.

A research group has made a material that can effectively separate heavy water from normal water at room temperature. Until now, this process has been very difficult and energy intensive. The findings have implications for industrial -- and even biological -- processes that involve using different forms of the same molecule.

Music and arts classes are often first on the chopping block when schools face tight budgets and pressure to achieve high scores on standardized tests. But it's precisely those classes that can increase student interest in school and even benefit their math achievement, according to a new study.

A new precision measurement of the proton's electric polarizability has confirmed an unexplained bump in the data. The proton's electric polarizability shows how susceptible the proton is to deformation, or stretching, in an electric field. Like size or charge, the electric polarizability is a fundamental property of proton structure. The data bump was widely thought to be a fluke when seen in earlier measurements, so this new, more precise measurement confirms the presence of the anomaly and signals that an unknown facet of the strong force may be at work.

A team of scientists believe our brains could use quantum computation, after adapting an idea developed to prove the existence of quantum gravity to explore the human brain and its workings. The brain functions measured were also correlated to short-term memory performance and conscious awareness, suggesting quantum processes are also part of cognitive and conscious brain functions. Quantum brain processes could explain why we can still outperform supercomputers when it comes to unforeseen circumstances, decision making, or learning something new, while the discovery may also shed light on consciousness, the workings of which remain scientifically difficult to understand and explain.

Electronic gaming can precipitate life-threatening cardiac arrhythmias in susceptible children whose predisposition may have been previously unrecognized, according to a new report. The investigators documented an uncommon, but distinct pattern among children who lose consciousness while playing electronic (video) games.

Researchers have long studied the color-changing properties of the natural mineral hackmanite upon exposure to UV radiation or X-rays. Now, the research group studied the reactions of synthetic hackmanite to nuclear radiation. The researchers discovered a one-of-a-kind and novel intelligent quality, gamma exposure memory, which allows the use of hackmanite as e.g. radiation detector.

Researchers have gained new insights into the chemical properties of the superheavy element flerovium -- element 114 -- at the accelerator facilities of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt. The measurements show that flerovium is the most volatile metal in the periodic table.

'You're so smart!' -- This encouraging response may actually do more harm than good to children's math performance, according to a new study. The study found that encouraging children with responses related to their personal traits or innate abilities may dampen their math motivation and achievement over time.

Nuclear magnetic resonance (NMR) is an analytical tool with a wide range of applications, including the magnetic resonance imaging that is used for diagnostic purposes in medicine. However, NMR often requires powerful magnetic fields to be generated, which limits the scope of its use. Researchers have now discovered potential new ways to reduce the size of the corresponding devices and also the possible associated risk by eliminating the need for strong magnetic fields. This is achieved by combining so-called zero- to ultralow-field NMR with a special hyperpolarization technique.

The protons and neutrons that build the nucleus of the atom frequently pair up. Now, a new high-precision experiment has found that these particles may pick different partners depending on how packed the nucleus is. The data also reveal new details about short-distance interactions between protons and neutrons in nuclei and may impact results from experiments seeking to tease out further details of nuclear structure.

How do different materials react to the impact of ions? This is a question that plays an important role in many areas of research -- for example in nuclear fusion research, when the walls of the fusion reactor are bombarded by high-energy ions. However, it is difficult to understand the temporal sequence of such processes. A research group has now succeeded in analyzing on a time scale of one femtosecond what happens to the individual particles involved when an ion penetrates materials such as graphene or molybdenum disulphide.

By using photons and electron spin qubits to control nuclear spins in a two-dimensional material, researchers have opened a new frontier in quantum science and technology, enabling applications like atomic-scale nuclear magnetic resonance spectroscopy, and to read and write quantum information with nuclear spins in 2D materials.
