Wrocław eye lasers offer short pulses to examine the retina
A laser that emits short pulses, developed at the Wrocław University of Science and Technology, now helps in examinations of the retina and will be useful for analysing nanomaterials and activating chemical reactions. Scientists plan to commercialise the device that can potentially replace older tools of this type in science and research.

Dance of the dunes...
Not every dune in a dune field moves at the same speed. It turns out that dunes can regulate each other's speed. What's more, they can share the sand 'fairly’.

LHCb: Correlations show nuances of the particle birth process
High-energy ion collisions at the Large Hadron Collider are capable of producing a quark-gluon plasma. But are heavy atomic nuclei really necessary for its formation? And above all: how are secondary particles later born from this plasma? Further clues in the search for answers to these questions are provided by the latest analysis of collisions between protons and protons or ions, observed in the LHCb experiment.

Polish physicists describe counter-intuitive quantum effect
Atoms escape from each other even though they are forced to attract each other? Polish physicists draw attention to the counter-intuitive quantum effect that, under certain conditions, occurs when the interactions between atoms suddenly change.

Brighter means darker: Counterintuitive X-ray lasers
The counterintuitive effect, in which the brighter the laser light beam, the weaker the diffraction image has been explained by physicists from Japanese, Polish and German scientific institutions. Understanding this phenomenon gives hope for the production of laser pulses that have significantly shorter pulse duration than those currently available, reports the Institute of Nuclear Physics of the Polish Academy of Sciences, involved in the research project.

Polish scientists reinterpret petroglyphs of Toro Muerto
The geometric patterns, lines and zigzags that accompany the images of dancers (danzantes) carved in the rocks of the Peruvian Toro Muerto are not snakes or lightning bolts, but a record of songs - suggest Polish scientists who analyse rock art from 2,000 years ago.
