Polish discovery concerning 'Brazil nut effect'
Scientists from the University of Warsaw and Utrecht University in the Netherlands have experimentally demonstrated for the first time that the Brazil nut effect does not require any energy supply. The discovery could be crucial for many fields of science and industry.

How to harness quantum mechanics to efficiently change information into useful energy?
Researchers are wondering whether knowledge in the field of quantum mechanics will allow them to convert information into mechanical work more effectively or in a completely new way. Polish physicist presents mathematical tools that will bring this branch of physics (quantum thermodynamics) closer to experimental stage.

How waves propagate in quantum droplets
In quantum droplets - a new state of matter, known only for a few years (a 'liquefied' Bose-Einstein condensate) - it is possible to observe unusual quantum waves called solitons with very interesting properties, according to the analyses of Polish physicists. A theoretical paper on this topic was published in the prestigious Physical Review Letters.

Nanotube 'big fish' bait to save most valuable nanotubes
Polish scientists have discovered a bait for 'nanotube big fish'. Their method will make it possible to separate all larger carbon nanotubes in one step and leave only the smallest ones that have a special potential for use in photovoltaics and nanomedicine.

What are the most accurate satellite time transfer systems?
An atomic clock does not always work better than a cheap quartz clock. Errors in satellite time transfer used to as accurately as possible synchronize clocks that are far apart may result from different reasons than previously thought, scientists from Wrocław have shown.

Scientists describe spontaneous avoid-dance of passers-by
Crowds of people heading in different directions meet at pedestrian crossings, stations and stadiums. Just like particles of matter in colloids or substances in some cells, these people spontaneously form traffic lanes. Researchers from Poland and the UK have just described the mathematical rules of this unusual dance in a publication in Science.

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.
