The main aim of this paper is to present recent knowledge about the assessment and evaluation of low frequency noise and infrasound close to the threshold of hearing and the potential effects on human health. Low frequency noise generated by air flowing over a moving car with the open window is chosen as a source of noise. The noise within the interior of the car and its effects on a driver’s comfort at different velocities is analyzed. An open window at high velocity behaves as a source of specifically strong tonal low frequency noise which is annoying. The interior noise of a passenger car was measured under different conditions; while driving on normal highway and roadways. First, an octave-band analysis was used to assess the noise level and its impact on the driver’s comfort. Second, a Fast Fourier Transform (FFT) analysis was used for the detection of tonal low frequency noise. Finally, the paper suggests possibilities for scientifically assessing and evaluating low frequency noise but not only for the presented source of the sound.
Prof. Edward Nęcka, a cognitive psychologist from the Jagiellonian University and Vice-President of the Polish Academy of Sciences, talks about cognitive misers, memory traps, and confusion in a myriad of new technologies.

To retain our cultural identity in the modern world and sensibly think about the future, we need to thoroughly study the past,” says Prof. Marek Figlerowicz from the PAS Institute of Bioorganic Chemistry, who leads the project “The Dynasty and Society of Piast-Era Poland in the Light of Integrated Historical, Anthropological, and Genomic Research.”
Prof. Anna Członkowska from the 2nd Department of Neurology at the Institute of Psychiatry and Neurology, a corresponding member of the Polish Academy of Sciences, discusses the definition of a stroke, new ways to help post-stroke patients recover, and reasons why time is of the essence.
“People generally associate my name with the first ever heart transplant in Poland. But I know that if I hadn’t tried to do it, then four, maybe five years later someone else would have. What I am sure of, however, is that no one else in Poland would have started working on developing an artificial heart. Had I not fought to create this device, a few hundred people would not be alive today because we wouldn’t have had ventricular assist devices which saved their lives and wellbeing.” – Zbigniew Religa, famous Polish cardiac surgeon
Designer drugs cause irreversible changes in the brain and put those who take them at an increased risk of developing Alzheimer’s and Parkinson’s disease. They can also affect one’s genetic material, says Prof. Krystyna Gołembiowska from the PAS Institute of Pharmacology.
Although the Antarctic has avoided the worst effects of alien species, its future seems endangered due to increasing natural and man-made pressures. Rapid changes in three major environmental variables have occurred in the Antarctic region during the last decades. In the short term terrestrial biota are likely to benefit from reduced environmental stresses, but in the long run the colonization of the region by lower latitude species with greater competitive ability will become increasingly important and can lead to large-scale changes in biological composition and trophic complexity in some existing Antarctic terrestrial ecosystems. Moreover, the recent dynamic climate changes combined with human activities in the Antarctic region might modify the status of several alien species which have hitherto been considered transient or persistent and could, therefore, become naturalized and threaten the native communities on a larger scale than today, or influence the status of naturalized species.
Is the fact that the majority of the population in the Middle East belongs to Islam actually the reason why human rights in Muslim-majority countries appear to be so difficult to work out and enforce? Are Islam and human rights not basically compatible? Historically it cannot be disputed that the thought of human rights first took shape in the European and Western context. Over the course of several centuries, it became widely accepted, and finally the thought of human rights also became a political reality as they were implemented in democratic states and constitutions. However, it would be a wrong conslusion, as for instance has been emphasized by Heiner Bielefeldt, the former United Nations Special Rapporteur on freedom of religion or belief, to say that the ability to implement human rights, in particular thoughts about freedom and the equality of all people, is a one-sided affair and can only occur in the Western-Christian context. As far as Heiner Bielefeldt is concerned, this historic development, however, justifies neither the assertion that it had to happen as it did, nor does it justify Western representatives’ taking sole occupation of considerations relating to human rights thinking. Viewed from this perspective, human rights cannot boast a “Western” origin or a “Christian” character in a way that they would be incompatible with notions justified by Islam. Having that said, one is still to a large degree able to recognize a desolate situation in matters relating to human rights in Muslim-majority countries. But conflicts between Islam and human rights do not arise automatically out of the religious affiliation of a majority of the people. They certainly do stand out in those places where for political decision-making authorities Sharia law ranks higher than human rights and the granting of human rights is made dependent upon a traditional interpretation of the Sharia. Apart from the societal advocacy of human rights, there is the question as to the framework within which theological assessments of human rights questions occur. The following article aims at pointing to three discernable positions about human rights in the context of Islamic theologians, the a) the inclusive position, b) the pragmatic position, and c) the progressive position.
According to some studies, the phenomenon of professional burnout has reached epidemic proportions in today’s world. This applies in particular to those whose jobs involve saving lives: firefighters, police officers, and doctors who perform operations as well as members of the so-called social professions, which are based on close relations with people. This also includes therapists.
