A Polish invention from the JU revolutionises the digital world

A Polish invention from the JU revolutionises the digital world

27.01.2020
Few people realise that the Polish invention developed at the Jagiellonian University known as the ANS coding or coding from the JU has become an essential part of the foundations of modern digital world. Thanks to the files compression method proposed by Dr Jarosław Duda from the JU Faculty of Mathematics and Computer Science, data can be transferred 30 times faster than before. What does this invention mean for the world and what are its possible implications?

Scientists discover the oldest material on Earth

Scientists discover the oldest material on Earth

23.01.2020
The Jagiellonian University has in its collection a fragment of the Murchison meteorite, which has recently been confirmed to contain the oldest known material on Earth: particles of cosmic dust created before the formation of the Solar System. In the past few days, an international research team published a paper in which they estimate these grains to be about seven billion years old.

JU archaeologists uncover the secrets of Mesa Verde

10.01.2020
Archaeologists from the Jagiellonian University have found out that some of the rock drawings made by Native Americans about 800 years ago in the canyons located in the border region between the US states of Colorado and Utah were linked to astronomic observations, such as determining the dates of summer and winter solstices. The pioneering archaeological research in this field has been led by Dr Radosław Palonka from the JU Department of American Archaeology.

Star Wars through the eyes of a physicist

Star Wars through the eyes of a physicist

19.12.2019
Star Wars is a cinematographic, artistic, technological and sociological phenomenon. George Lucas’ saga has millions of fans all over the world, whose total number is hard to estimate. Their community also includes physicists who approach the films from a more scientific point of view. Selected aspects of Star Wars have been analysed by Dr Witold Zawadzki, a physicist from the Faculty of Physics, Astronomy and Applied Computer Science of the Jagiellonian University.

A unique butterfly in the collection of the Natural Sciences Education Centre

12.12.2019
Employees of the JU Natural Sciences Education Centre have been studying and cataloguing various species of butterflies worldwide, collaborating with the most important research centres and entomologists in Europe and America. Their work has resulted in several hundred papers and the discovery of nearly 300 new species from the tropical regions of Africa and South America.

History written anew

History written anew

11.12.2019
Until relatively recently, many historians held a belief that fourteen centuries ago the streets of Constantinople were swarming with dead or dying people. It was thought that an unknown disease swept over the Byzantine Empire (and the rest of Europe), killing about half of its populace.

How plants deal with stress

How plants deal with stress

09.12.2019
Throughout their existence, human beings have been accompanied by stress, and hence they have developed various methods to reduce it. Plants are also subject to stress, caused by adverse environmental factors (such as water or light deficiency), but unlike most animals they cannot hide or run away from danger. Dr Paweł Jedynak from the JU Department of Plant Physiology and Biochemistry discusses how to recognise and interpret the symptoms of stress in plants and what are the mechanisms that allow them to live through stressful situations.

Head lice – more common than you think

Head lice – more common than you think

25.11.2019
With the beginning of every school year, there inevitably comes a series of reports on the rising tide of head lice infestations. It may seem that the advances we’ve made in sanitation and medicine should eliminate the presence of such parasites from our daily lives. How come we are still experiencing these ‘head lice outbreaks’?

JU astronomers contribute to the discovery of a very-high-energy gamma-ray burst

21.11.2019
After a 10-year-long search, scientists have finally detected a very-high-energy (VHE) gamma-ray burst. The discovery was made by the international research team of the High Energy Stereoscopic System (H.E.S.S.), using the 28-metres long telescope located in Namibia. It unexpectedly turned out that this burst resulting from a cosmic cataclysm remained within the VHE gamma spectrum very long after the initial explosion.

Where does the body end? Where does the mind begin?

Where does the body end? Where does the mind begin?

18.11.2019
Not everyone finds it easy to delve into subject matter as complex as cognitive neuroscience and behavioural studies. For some, the very idea of exploring these issues seems redundant and pointless, since there is no apparent gain from studying them. Embodied cognition? Situated conceptualisation? What are they and what are they for? Since we’re nearing the upcoming lecture by Prof. Piotr Winkielman dedicated to this topic, a brief introduction is definitely in order.
