    Bose-Einstein condensation of photons in laser

    Scientists from Wrocław University of Science and Technology offer a new perspective of the principles of operation of semiconductor lasers. The results of their important laser physics discovery have just been published in the journal Nature Photonics.

    Tornado in a box: Twisted Polish idea for quantum memory

    Physicists from Warsaw have built a trap for 'quantum tornadoes' - single quantum vortices that appear in superconductors. Thanks to the world's fastest thermometer of their own design, they have studied these vortices and determined how to control them. Now scientists propose to use this idea as memory in quantum computers.

  • Distortions in different projections. On a 'perfect map', circles - covering the same areas - would be the same size and shape in every place on the map. Source: collage of maps shared on Wikipedia

    Maps can be deceiving and have serious consequences, says mathematician

    Just as statistics or graphs can distort reality, so can the maps we use every day. However, if you learn the mathematics hidden behind maps, you will not be so easily led astray, says mathematician Dr. Paulina Rowińska.

  • The Higgs boson (blue) may form as a result of the interaction of gluons (yellow) during proton collisions. Protons consist of two up quarks (red) and one down quark (purple), bound by gluons so strongly that in the forming sea of virtual particles (gray) more massive quarks and antiquarks, for example beauty quarks, may appear, and their presence also affects the Higgs boson birth process.

    After 12 years of research, Higgs still does not reveal elements of new physics

    After 12 years of detailed research into the properties of the Higgs boson, there is no indication that it will be possible to extend the Standard Model with elements of new physics - new analyses involving Polish scientists show.

    Time for visitors from the future? Why not! Physicists make room in theory for tachyons

    Tachyons are hypothetical particles that travel at speeds faster than light. Until recently, they were generally regarded as entities that did not fit into the special theory of relativity. However, a team of physicists has just demonstrated how to make room for tachyons in theory.

    Work is underway on Polish far infrared detector array

    Researchers at the Military University of Technology are working on the future Polish array of far infrared detectors, the components of which will be environmentally friendly and at the same time meet the requirements of the most advanced applications, including military ones.

  • River deltas can have a variety of forms. The Ganges-Brahmaputra River Delta in Bangladesh (left) shows a loop-like topology, with numerous channels interconnecting primary branches (Source: @ESA European Space Agency). The outflow from Wax Lake in Louisiana seems to branch into a treelike pattern with smaller river outlets reaching the Atlantic Ocean (Source: National Science Foundation, Center for Earth-Surface Dynamics).

    Scientists investigate ‘network loops’ in nature

    In blood vessels, leaf veins and river systems, physicists see so-called transport networks. What conditions favour the formation of loops that make the entire system resistant to damage has now been investigated by a team of scientists from Poland and America.

    Galvanization like printing - coatings for solar cells and more

    A new method of coating materials with thin layers in a way that resembles printing has been developed at the Jagiellonian University. It requires a minimal amount of chemical materials and can accelerate the development of 3rd generation organic solar cells.

    World of atoms and molecules: see the 'entire elephant' with different imaging methods

    The structure of the molecules that make up cells can be explored with various imaging techniques. Contrary to appearances, the maps of the same structures obtained with different techniques are slightly different from each other. To 'see the entire elephant' we need a combination of techniques, and a thorough knowledge about the mode in which they probe the matter, says Dr. Matthias Bochtler from the International Institute of Molecular and Cell Biology in Warsaw.

The mystery of Type Ic supernovae: Dramatic relationships of binary stars

Type Ic supernovae carry within them a dramatic story of a relationship between a pair of stars. An international team of scientists led by Polish researchers has proven that for this type of cosmic explosion to occur, a not-so-peaceful - by human relationship standards - binary star system is needed.
