Another mystery of photosynthesis solved
20.04.2021
Studies into the mechanisms of photosynthesis have been conducted for a long time. This unique process is of special interest to scientists, as at helps plants to utilise solar energy on a mass scale. Until now some chemical reactions determining this process remained unknown. This has changed thanks to new research conducted by a group of scientists, which includes researchers from the Jagiellonian University. Dr Michał Gabruk from the JU Faculty of Biochemistry, Biophysics and Biotechnology sheds some light on this issue.

Bees on a forced diet
23.03.2021
All pollinators, including the most well-known ones – bees – subsist on a rich and varied diet, the staple of which are pollen and nectar supplied by trees, bushes and other flowering plants. Nectar gives the pollinators the energy to go about their day, while pollen is used as building blocks for the organisms of their offspring. A healthy bee needs high quality food, but obtaining it isn’t that simple. Dr Zuzanna Filipiak and Dr Michał Filipiak from the JU Institute of Environmental Sciences investigate this issue in their research project.

Mars en masse
17.02.2021
So far, in 2021 there have been numerous Mars missions, extensively covered by the media. This is due to the fact that last year several institutions sent probes to the Red Planet at a similar time, which, in turn, was caused by Mars’ great opposition that took place in autumn, meaning that its orbit was as close to Earth’s as it can possibly get. These favourable conditions allowed the United Arab Emirates to join the exclusive club of states which managed to send their equipment to Mars’ orbit.

Is facial symmetry a sign of good health?
22.01.2021
Research suggests that people with more symmetric faces are perceived as more attractive, have better developed immune system, and are more resistant to upper respiratory tract infections. What are the reasons for and the implications of this relationship? Dr hab. Urszula Marcinkowska Trimboli from the JU MC Institute of Public Health will shed some light on this issue.

Why do large stars shine? We know the answer
03.12.2020
The international team of about 100 researchers, including scholars from the JU Institute of Physics that conduct the BOREXINO experiment in the underground laboratory in Gran Sasso (Italy), have announced that they have finally determined why large stars are shining. Their discovery was published in the latest issue of Nature.

A legendary radio telescope passes into history
24.11.2020
The giant radio telescope Arecibo will soon cease to exist, as decided by the US National Science Foundation (NSF). The enormous antenna has been breaking down for quite a long time, and, according to experts, its possible repair would be too dangerous to its future operators. Dr Elżbieta Kuligowska from the Astronomical Observatory of the Jagiellonian University gives a commentary on the decommissioning of one of the world’s most famous astronomical facilities.

The glymphatic system: working the night shift
19.11.2020
The glymphatic system is the analogue of the lymphatic system of the brain, with the ‘G’ in the front of the word standing for ‘glia’, or ‘glial cells’ that are part of it. Its aim is to remove any unnecessary remains of metabolic processes – a very important task, considering that these remains may prove harmful to the brain. It’s been observed that the glymphatic system is more active when we sleep. Dr hab. Marta Obara-Michlewska from the Mirosław Mossakowski Institute of Experimental and Clinical Medicine of the Polish Academy of Science discussed the subject during a lecture as part of the International Brain Awareness Week 2020.

Eavesdropping on dark matter
16.11.2020
In the latest issue of Nature Astronomy, a research team consisting of scientists from around the world presents its findings concerning dark matter particles. One of them, Dr hab. Szymon Pustelny from the JU Faculty of Physics, Astronomy and Computer Studies, shared some insights about ‘eavesdropping’ on dark matter and why it’s so important.

How long is too long?
09.11.2020
We celebrate our birthdays to mark the fact that we have lived yet another year on planet Earth, but how many birthdays are too many? One of the greatest challenges facing contemporary medicine is not extending the lifespan of a person, but rather keeping that person in good health until their final days. Currently, our physical and mental health is threatened chiefly by neurodegenerative diseases with unknown aetiology. These neurodegenerative diseases were the subject of the lecture delivered by Dr hab. Grzegorz Kreiner from the Department of Brain Biochemistry of the Polish Academy of Sciences during the International Brain Awareness Week.

Medicine: from the clinic to the drugstore
30.10.2020
Advances in medicine and access to better and better drugs is possible thanks to scientific research in the field of biomedicine. Substances are first tested in pre-clinical trials using tissues, computer models and laboratory animals. If the results are promising, drugs enter the clinical trial phase, during which they are tested on human volunteers. It is only upon the completion of this phase that medicine is cleared for sale at drugstores.
