    European forest plants migrate 3.5 km per year, new study finds

    As a result of human activity, European forest plants shift their ranges not only towards the poles, as was commonly believed, but also westwards, according to research by an international team including Polish scientists.

    Polish scientists in PNAS: When should competition turn into cooperation? Physics of transport networks explains it

    River deltas, leaf veins, lightning... in transport networks, simple laws of physics can surprisingly lead to cooperation between previously competing parts of the system, increasing its efficiency, shows research published in PNAS by Polish scientists.

    Researchers in Wrocław develop bionic hand

    Scientists from the Wrocław University of Science and Technology are completing work on a prototype bionic hand prosthesis for people with forearm amputations. The device is controlled with signals sent by muscles on the stump of the amputated limb, and artificial intelligence is used to analyse them.

    New image of famous artefacts thanks to computed tomography

    Scientists from the Wrocław University of Technology and the University of Wrocław used technical computed tomography to re-examine a harpoon made of roe antlers and a bear bone from thousands of years ago. Thanks to new techniques, we can learn more even about very old discoveries, says Dr. Tomasz Płonka from the University of Wrocław.

    Was the steppe bison specialised herbivore of Pleistocene landscapes?

    The results of new research challenge the common view that the steppe bison was a strictly grazing animal, feeding mainly in the steppes, say scientists from the Mammal Research Institute PAS, who reconstructed the diet of the last representatives of the legendary megafauna.

    Butterflies can travel thousands of kilometres, but their migrations are still poorly known, says researcher

    Butterflies are associated with fragility, but they can fly several thousand kilometres using air currents, among other things. Their migrations are still poorly known, however, and they cannot be tracked as easily as birds, using rings or GPS transmitters, says botanist and ecologist Dr. Tomasz Suchan.

    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.

    There is a revolution in the Polish space sector, says expert

    In recent months, the Polish space sector has recorded spectacular successes, including the successful test of the Bursztyn rocket and the launch of the EagleEye satellite, believes Łukasz Wilczyński, president of the European Space Foundation. He adds that the challenge for Poland now is to determine the main directions of development of this sector.

    Biologists from University of Lodz investigate whether plants can help get rid of 'forever chemicals'

    Biologists from the University of Lodz are investigating whether plants can be used to remove 'forever chemicals' from the soil. These are non-biodegradable chemical compounds known as perfluoroalkyl substances (PFAS) that pose a serious threat to the environment and human health.
