Scientists have proven that 800-year-old pedunculate oaks can be multiplicated by the in vitro cloning method. Previously, this was only possible for up to 300 years old oaks. Their work will enable the preservation and protection of the genetic resources of valuable specimens growing in Poland.
Dr. Bartłomiej Tomasik from the Medical University of Gdańsk is the co-discoverer of a previously unknown mechanism of DNA repair by cells. Gene repair is crucial for the development and treatment of cancer.
A 2,000-year-old dice (the oldest one found so far in Poland) is among this year's discoveries in the Celtic settlement in Samborowice (Silesia).
Archaeologists working in Zwoleń (Masovian Voivodeship) have found animal bones and flint tools from Neanderthal times. They completed the first stage of work at the site, to which scientists returned 30 years after the previous research project.
A Polish-Chinese scientific team has described a new marine reptile that lived about 250 million years ago in what is now China. The discovery sheds new light on the evolution of the aquatic lifestyle of extinct reptiles and confirms the close relationship of turtles with dinosaurs and their relatives.
Archaeologists working in Racibórz have discovered stone products from at least 130,000 years ago. These are the oldest traces of human presence in the foreground of the Moravian Gate and a proof that Neanderthals visited this region several times, leaving stone products at the bottom of the then river valley.
Plastics take many years to completely disappear from the environment, but they are among the most rapidly deteriorating materials in cultural heritage objects, says scientists dealing with the degradation and protection of works of art.
A whole world of possibilities opens up to scientists if they know how to lock chemical compounds in tiny cages in a controlled manner, and then open these capsules, explains chemist Dr. Wojciech Drożdż.
It is extremely durable, it combines the best properties of metals and ceramics and can fly into space. Scientists from Łukasiewicz - Poznań Institute of Technology have just developed a new, cheaper and faster method of producing the so-called MAX phase material.
Supporting the process of fish reproduction in the event of an ecological disaster, securing the stability of breeding in fish hatcheries and protecting the gene pool - these are the main objectives of fish semen banks, which are being established by scientists from the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn.
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.
