Gas column density 5 Myr after stars begin forming in the “real” Clouds (left panels) and corresponding Spheres (right panels). The Spheres begin forming stars 5-6 Myr after t=0, so the figure shows simulations at a similar stage of star formation. Clouds show more widespread star formation, and alignment of their major gas filaments along the larger-scale structures present in the galaxy. (Credit: Rey-Raposo, Dobbs & Duarte-Cabral 2014)

German winner of the Nobel Prize for chemistry Stefan Hell gestures at a small party with his colleagues in Goettingen, Germany, Wednesday, Oct. 8, 2014. Hell shares the prize with Americans Eric Betzig and William E. Moerner for developing ways to dramatically improve the resolution of optical microscopes. Hell developed the underlying technology for R&D 100 Awards-winning super-resolution microscopes from Leica. (Credit AP/dpa, Swen Pfoertner)

The illustration shows how oscillating photons create an image of frozen light. At first, photons in the experiment flow easily between two superconducting sites, producing the large waves shown at left. After a time, the scientists cause the light to ‘freeze,’ trapping the photons in place. Fast oscillations on the right of the image are evidence of the new trapped behavior.

The quasicrystals formed 4.5 billion years ago in a violent collision between two rocks, among the asteroids that coalesced into planets. The rock with the quasicrystals landed in Chukotka as a meteorite. “They’re part of the primal stuff that formed our solar system,” Dr. Steinhardt said.

The NASA/ESA Hubble Space Telescope has produced this finely detailed image of the beautiful spiral galaxy NGC 6384. This galaxy lies in the constellation of Ophiuchus (The Serpent Bearer), not far from the centre of the Milky Way on the sky. The positioning of NGC 6384 means that we have to peer at it past many dazzling foreground Milky Way stars that are scattered across this image. (Credit NASA/ESA)

he problem was first identified some time ago. Dubbed the “cosmological lithium discrepancy,” the issue is very simple: everything we know about the Big Bang, supernovae, and the dynamics of stars, tells us that we should find a very specific concentration of lithium in the universe at large — but the universe actually seems to contain far less than that amount.

“I confess that in my early in my career as a physicist I was rather cynical about sophisticated statistical tools, being of the opinion that “if any of this makes a difference, just get more data”. That is, if you do enough experiments, the confidence level will be so high that the exact statistical treatment you use to evaluate it is irrelevant.” (Credit: Jon Butterworth)
