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.
In Southeast Asia, population growth and the demand for agricultural land are causing significant changes in biodiversity, resulting in an increasing epidemiological risk. This risk concerns viruses such as coronaviruses, bird flu virus, MERS, USUTU, Zika, dengue and malaria, says Dr. Aneta Afelt from the University of Warsaw.
The vast majority of wetlands in Poland and Europe have already been drained for various purposes. Meanwhile, draining peatlands and, for example, introducing forest in their place brings much lower economic benefits than rewetting them. A team of scientists with the participation of Polish researchers have shown that in Lithuania, rewetting drained forest peat bogs would bring profits of up to EUR 170 million per year.
The Joint European Torus (JET) in Oxford managed to achieve a thermonuclear reaction lasting five seconds with a record amount of energy produced. This is an important milestone on the path to fusion energy. More than 300 scientists associated with the EUROfusion consortium, including researchers from the Polish Institute of Plasma Physics and Laser Microfusion in Warsaw (IFPiLM), took part in the experiment, the results of which were presented last week.
A team of scientists, including Dr. Mariusz Gromadzki from the Astronomical Observatory of the University of Warsaw, has identified a previously unknown source of cosmic dust, the university reports. The dust was produced by the interaction of the matter ejected during a la supernova explosion with the surrounding circumstellar gas.
Wrocław University of Science and Technology and two Polish companies have developed an ice battery that stores surplus energy in the form of cold energy - and releases it in the form of heat at a later time, for example when electricity is more expensive. The system can be used mainly by companies that need large amounts of heat energy.
Well-preserved DNA of several hundred species of bacteriophages from over a thousand years ago - viruses that infect bacteria - have been found in samples of human faeces and in the guts of an ancient mummy. It turns out that the genome of one of the species is almost the same as that of modern viruses. Why has the evolution of this species halted for so long?
