According to Efimov’s prediction, bound states of three atoms can be universally described under certain conditions. The scientist found that infinitely many quantum mechanical bound states for the “ménage à trois” exist, even if two of the atoms cannot bind together. (Credit: Heidelberg Uni.)

Delicate Arch and many other gigantic arches in the US are made of the stuff. It is a “locked sand”, whose angular grains can catch on each other.(Credit: Brad Goldpaint/Aurora Open/Corbis)

Herschel image of the Helix Nebula using the SPIRE instrument at wavelengths around 250 micrometres, superimposed on Hubble image of the nebula. The spectrum corresponds to the outer region of the Helix Nebula outlined on the SPIRE image. It identifies the OH+ molecular ion, which is needed for the formation of water. ESA’s Herschel space observatory is the first to detect this molecule in planetary nebulas – the product of dying Sun-like stars. Credit: Hubble image: NASA/ESA/C.R.

2-D-EV spectral data tells researchers how photoexcitation of a molecular system affects the coupling of electronic and vibrational degrees of freedom that is essential to understanding how all molecules, molecular systems and nanomaterials function. Credit: Fleming group
Manipulating minute areas of gain and loss within individual lasers (shown as peaks and valleys in the image), researchers were able to create paradoxical interactions between two nearby lasers. Credit: Vienna University of Technology
This is an artist’s concept of the metric expansion of space, where space (including hypothetical non-observable portions of the universe) is represented at each time by the circular sections. Note on the left the dramatic expansion (not to scale) occurring in the inflationary epoch, and at the center the expansion acceleration
This is a computer simulation of gas (in yellow) falling into a black hole (too small to be seen). Twin jets are also shown with magnetic field lines. Credit: Alexander Tchekhovskoy, Berkeley Lab
