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.

How long is too long?
10.11.2020
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.
