Polish scientists have found that a method similar to Nobel Prize-winning click chemistry can be used to improve the luminescence of nanomaterials. It is enough to disrupt the symmetry of carbon nanotubes using azides. 'Asymmetrical like a the Mona Lisa's smile', nanotubes can be used to detect the early stages of diseases.
Brittle stars, animals with five-segment radial (pentaradial) symmetry, lived millions of years ago in the territory of present-day Poland. They survived, although today they can only be found in high salinity waters. Fossil species of these agile echinoderms found in Kujawy and the Krakow-Częstochowa Upland have been described by scientists from Warsaw.
Where do heavy metals in the Norwegian fiord Hornsund in Spitsbergen come from? Scientists from the Institute of Oceanology of the Polish Academy of Sciences investigate their source in collaboration with the Institute of Geophysics of the Polish Academy of Sciences and the Institute of Earth Sciences and the Centre for Polar Studies of the University of Silesia in Katowice.
Apples and citrus fruits sold in Poland today are contaminated with pesticides to a much lesser extent than a decade ago, scientists from the University of Life Sciences in Lublin have found. They attribute this to the introduction of regulations that specify the maximum residue limit for pesticides in fruit.
