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.
Archaeologists have discovered a unique collection of fabrics and shoes - mainly from the 16th and 17th centuries - during research at the construction site of the Camerimage film centre in Toruń. The finds include well-preserved silk fabrics, fragments of pleated dresses and a cloth of gold with a floral ornament.
A doctoral candidate at the University of Lodz has built a sensor for non-invasive monitoring of the water level in the body. The device may help in the early detection of heart failure.
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.
AI algorithms combined with satellite Earth observation systems effectively detect diseases of peatland vegetation, according to research conducted by scientists from the Remote Sensing Centre of the Institute of Geodesy and Cartography.
After 20 years of membership in the EU, Poles are more Euro-realists than Euro-enthusiasts; they see the advantages of the EU, their benefits of being in this community, but they also soberly and often critically look at the EU bureaucracy, says Professor Stanisław Mocek, sociologist and media expert, Rector of Collegium Civitas.
We know lycaons from Africa, but about half a million years ago these predatory mammals also existed in the lands of today's Poland. Scientists who examined the remains of the last Eurasian lycaon from the Wieluń Upland call it the canine Jack the Ripper. It was able to knock down very large prey and eat its entire body.
Energy absorbers absorb the kinetic energy of accidents, collisions and falls to protect passengers and vehicles. Researchers from Warsaw have developed cheap absorbers made of innovative composite materials, which can be used, for example, to build airline seats and airplane floors, as well as crash boxes in cars.
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.
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.
