Based on an extensive study across environments, from mixed conifer forest to high-desert grassland, the team suggests that microbes aren't so different from larger, more complex forms of life. That is, in determining species traits, nature takes the lead, while nurture plays a supporting role.
Scientists made the first direct, definitive measurement of the weight, also known as the mass number, for two superheavy nuclei.
The Dark Energy Survey has combined its four primary cosmological probes for the first time in order to constrain the properties of dark energy.
A team devised a way to bridge the gap between two extremes. Using their approach, they can predict catalyst performance across a wider range of temperatures and pressures.
Researchers developed molecular flypaper that recognizes and traps viruses, bacteria, and other pathogens.
Some metals need to be protected from the atmosphere. Exposure leads to damage that ruins their unique properties. Controllably forming metal islands just under the surface of graphite protects the metals. This allows these metals to take on new roles in ultrafast quantum computers. It also means new roles in magnetic, catalytic, or plasmonic materials.
Scientists devised specialized X-ray mapping techniques. They determined that boundaries associated with regions where atoms are closely packed together most readily resist cracking. This analysis revealed that when a crack encounters such a boundary, it's deflected to a less direct path and crack growth is slowed.
Scientists used chemically sensitive X-ray microscopy to map lithium transport during battery operation.
Six new nuclear reactor technologies are planned to commercially deploy between 2030 and 2040. ORNL's Weiju Ren heads a project managing structural materials information. This conversation explores challenges and opportunities in sharing nuclear materials knowledge internationally.
How atoms react to a sudden burst of light shows scientists how the larger material might act in sensors, data storage devices, and more.
Warp+PXR dramatically improves the accuracy of the simulations compared to those typically used in plasma research. Now, researchers can simulate lasers' interactions with plasma with much higher precision.
Superconductors are materials that show no resistance to electrical current when cooled. Recently, scientists discovered a new superconducting material. Now, scientists have found that when exposed to low-energy ultraviolet light, the material acts as a superconductor at higher temperatures.
The OARtrac(r) system includes technologies that are based on a novel application of scintillating material in fiber form. Doctors can insert these scintillating fibers into the human body via a catheter to monitor the radiation that cancer patients receive in a range of hard-to-reach areas.
A team devised a way to better model water's properties. They developed a machine-learning workflow that offers accurate and computationally efficient models.
For the first time, a team determined and predictably manipulated the energy landscape of a material assembled from proteins. Designing materials that easily and reliably morph on command could benefit water filtration, sensing applications, and adaptive devices.
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.
To better store data, scientists need ways to change a material's properties suddenly. For example, they want a material that can go from insulator to conductor and back again. Now, they devised a surprisingly simple way of flipping a material from one state into another, and back again, with flashes of light. A single light pulse turns thin sheets of tantalum disulfide from its original (alpha) state into a mixture of alpha and beta states. Domain walls separate the two states. A second pulse of light dissolves the walls, and the material returns to its original state.
Supercomputer validates mathematical approach for describing geological features.
How do you determine the measurable "things" that describe the nature of our universe? To answer that question, researchers used CosmoFlow, a deep learning technique, running on a National Energy Research Scientific Computing Center supercomputer. They analyzed large, complex data sets from 3-D simulations of the distribution of matter to answer that question. The team showed that CosmoFlow offers a new platform to gain a deeper understanding of the universe.
