Dinosaurs could have used the feathers on their forelimbs and tails to rouse and chase their prey, suggest Professor Piotr Jabłoński and a team from Korea. To confirm this hypothesis, the researchers built a robot - Robopteryx that scares insects - and examined the neurons of grasshoppers.
Subjectively perceived social position is strongly related to health. The lower you assess your social status, the higher the risk of developing various diseases and the risk of death from various causes, a researcher from the University of Warsaw says.
Polish scientists have discovered an over two-meter-long predatory armoured fish with an extremely elongated lower jaw in rock sediments from 365 million years ago in the Świętokrzyskie Mountains. The remains do not resemble any other animals from the Devonian.
Aneurysms of various shapes and sizes, previously imaged in patients, will be virtually 'operated on' in many possible ways. This will lead to the creation of software that will help neurosurgeons secure them against breaking and growing.
Scientists are now able to check how the ice mass is changing in Greenland and Antarctica, where measuring instruments cannot be installed. The new method involves determining changes in the Earth's shape based on observations of anomalies in the movement of artificial satellites and 'orbit memory'.
