Some years ago, Rudolf Grimm's team of quantum physicists in Innsbruck provided experimental proof of Efimov states – a phenomenon that until then had been known only in theory. Now they have also measured the second Efimov resonance of three particles in an ultracold quantum gas, thus, proving the periodicity of this universal physical phenomenon experimentally....
After years of calculation, planning, component production and installation the Wendelstein 7-X project is now entering a new phase: Max Planck Institute for Plasma Physics (IPP) in Greifswald in May started the preparations for operation of this the world's largest fusion device of the stellarator type....
People standing on a beach often feel the water tugging the sand away from under their feet. This is the undertow, the current that pulls water back into the ocean after a wave breaks on the beach....
The recent BICEP2 observations – of swirls in the polarisation of the cosmic microwave background – have been proclaimed as many things, from evidence of the Big Bang and gravitational waves to something strange called the multiverse....
University of Central Florida physicist Zenghu Chang has done it again. For a third time this year, his research group has published an article in a Nature Photonics journal....
(Phys.org) —Astrophysicists at UC San Diego have measured the minute gravitational distortions in polarized radiation from the early universe and discovered that these ancient microwaves can provide an important cosmological test of Einstein's theory of general relativity. These measurements have the potential to narrow down the estimates for the mass of ghostly subatomic particles known as neutrinos....
(Phys.org) —A simple new technique to form interlocking beads of water in ambient conditions could prove valuable for applications in biological sensing, membrane research and harvesting water from fog....
Although it may not be herding cats exactly, all the NASA-supported Binary Colloidal Alloy Tests (BCAT) studies have ended on the International Space Station, and the experimental samples are being rounded up and returned to the participating scientists. The BCAT series of investigations aims to understand fluids and the physics behind their movement. This research might help in designing new stable...

(Phys.org) —It may be surprising, but in physics the terrain of atoms and the territory of organic molecules are worlds apart. Therefore, in order to have a molecule communicate optically with atoms, the physicists must put in a similar amount of effort as most Europeans do when they want to learn Chinese. A team from the Max Planck Institute for Solid State Research and the University of Stuttgart...
There is an optimum size for electrical networks if what is being considered is the risk of a blackout. This is the conclusion reached by a scientific study done by researchers at Universidad Carlos III in Madrid; the study analyzes the dynamics of these complex infrastructures....
Although Dark Energy and Dark Matter appear to constitute over 95 percent of the universe, nobody knows of which particles they are made up. Astrophysicists now crossed one potential Dark Matter candidate – the Dark Photon or U boson – off the list in top position. This is the result of recent HADES experiments, where researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and from 17 other...
A large gray whale and a much smaller skipjack tuna each propels itself through water. Which is the more efficient swimmer? It has been difficult to compare propulsion efficiencies of animals of different sizes, like comparing apples and oranges, but now Northwestern University researchers have developed a new metric, or standard, to measure individual energy consumption efficiency and make such a...
