Scientists have re-examined the remains of a prehistoric marine reptile found in the 20th century in the village of Załęcze Wielkie (Łódź province). This distant relative of modern crocodiles was about four metres long and had a visible jaw injury, which it probably suffered in the first years of its life.
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.
The properties of nanomaterials depend on how these structures vibrate, among other things. Scientists, including a Polish researcher, investigated the vibrations occurring in various types of carbon nanotubes.
When the molecules of a certain compound - tetracene - are arranged in the shape of a nano-snowflake, singlet fission occurs - a process that obtains as many as two electrons from one photon, Polish and Taiwanese scientists have shown. They hope that their research will help improve the efficiency of solar panels.
Astronomers from the Astronomical Observatory at the University of Warsaw have discovered a massive variable star, i.e. a classical Cepheid, with the longest pulsation period in our galaxy. According to researchers, it is not only the brightest, but also probably the youngest known classical Cepheid in the Milky Way. It is 22 million years old.
Trachelosaurus, a newly discovered reptile that lived about 245 million years ago, had a very long neck and a long spine. An international team of palaeontologists demonstrated this by going back to a description from a hundred years ago, when the bones were believed to come from several animals. Today it is known that they were the skeleton of one individual.
Trematosaurs, early Triassic amphibians that resembled today's crocodiles, lived also in the areas of today's Poland 250 million years ago, researchers from the Institute of Paleobiology of the Polish Academy of Sciences and the University of Warsaw have shown.
Thanks to the Gaia Observatory, the European Southern Observatory's telescope and other ground-based instruments, scientists have tracked down a record-breaking black hole in our galaxy. Polish astronomers from the Astronomical Observatory of the University of Warsaw took part in the research.
According to applicable regulations, wind turbines are treated like any other source of industrial noise. This needs to change, says Professor Anna Preis from the Adam Mickiewicz University in Poznań, leader of the HETMAN project, which investigated the noise of wind turbines.
Electrical brain signals in patients with multiple sclerosis, a disease mainly associated with the slowing-down of information processing and a lack of motor coordination, show traces of multifractality, scientists from four Polish research institutions have found.
