Smallest Swiss cross—made of 20 single atoms

20 bromine atoms positioned on a sodium chloride surface using the tip of an atomic force microscope at room temperature, creating a Swiss cross with the size of 5.6nm. The structure is stable at room temperature and was achieved by exchanging chlorine with bromine atoms. (Credit: Department of Physics, University of Basel)

A Critical Test of Quantum Criticality

a) An example of the classical phase transition in a ferromagnet. Thermal fluctuations causing the random reorientation of the constituent spins grow with temperature. They compete with the tendency of the local magnetic fields to align the spins. As a result, the net magnetization in the ordered state continuously decreases with temperature (orange line) and drops to zero at a critical temperature Tc, surrounded by a narrow critical region (dashed rectangle). (b) A generic example of the quantum phase transition. Quantum fluctuations controlled by the nonthermal parameter g lead to a similar phase transition at a critical value gc, the so called quantum critical point, already at zero temperature, T=0. Their interplay with thermal fluctuations opens up a progressively broader, V-shaped quantum critical region extending much above the zero temperature (dashed lines).

Growth of structure tells us how normal and dark matter scatter

The colored curves describe different velocity dependencies of the scattering strength; it is scaling as v to the nth power. The horizontal axis, k, is a measure of how separated two points in space might be; larger k corresponds to smaller physical separation. The vertical axis (technically known as a “power spectrum”) describes how correlated two points separated by a scale 1/k are; higher number mean more correlation. The one point with error bars shows that most of the models the authors consider are not very favored by the data. (Credit: C. Dvorkin, K. Blum, and M. Kamionkowski)

Uncertainty gives scientists new confidence in search for novel materials

This image shows the results of calculations aimed at determining which of six chemical elements would make the best catalyst for promoting an ammonia synthesis reaction. Based on thousands of these calculations, which yielded a range of results (colored dots) that reveal the uncertainty involved, researchers estimated an 80 percent chance that ruthenium (Ru, in red) will be a better catalyst than iron (Fe, in orange.)

NASA 3D prints a model of light-year-long Eta Carinae nebula

A new shape model of the Homunculus Nebula reveals protrusions, trenches, holes and irregularities in its molecular hydrogen emission. The protrusions appear near a dust skirt seen at the nebula's center in visible light (inset) but not found in this study, so they constitute different structures.

MESSENGER and STEREO measurements open window into high-energy processes on the Sun

A solar flare erupted on the far side of the sun on June 4, 2011, and sent solar neutrons out into space. Solar neutrons don't make it to all the way to Earth, but NASA's MESSENGER, orbiting Mercury, found strong evidence for the neutrons, offering a new technique to study these giant explosions.
