O pochodzeniu, umiejętnościach i inteligencji psów nierasowych mówi prof. dr hab. Wiesław Bogdanowicz z Instytutu Zoologii PAN.

The Bulletin of the Polish Academy of Sciences: Technical Sciences (Bull.Pol. Ac.: Tech.) is published bimonthly by the Division IV Engineering Sciences of the Polish Academy of Sciences, since the beginning of the existence of the PAS in 1952. The journal is peer‐reviewed and is published both in printed and electronic form. It is established for the publication of original high quality papers from multidisciplinary Engineering sciences with the following topics preferred: Artificial and Computational Intelligence, Biomedical Engineering and Biotechnology, Civil Engineering, Control, Informatics and Robotics, Electronics, Telecommunication and Optoelectronics, Mechanical and Aeronautical Engineering, Thermodynamics, Material Science and Nanotechnology, Power Systems and Power Electronics.

Dla wielu ludzi Arktyka to nie chwilowy przystanek, ale dom. Naukowcy muszą więc odpowiedzieć nie tylko na pytanie, co ona znaczy dla świata, lecz także jak świat może pomóc jej mieszkańcom.

Umiemy już manipulować płynami w mikroskali. Jednym z najciekawszych zastosowań technik mikroprzelywowych jest precyzyjne tworzenie bąbelków i kropelek; metody te z czasem posłużą do konstrukcji miniaturowych laboratoriów chemicznych.

Urządzenia o rozmiarach nanometrów wykorzystujące maszyny molekularne mogą odegrać podstawową rolę w rozwoju przyszłej elektroniki, medycyny i komunikacji. Tworzenie cząsteczek z fragmentów molekularnych, które pod wpływem przyłożonych bodźców mogą się poruszać względem siebie tak jak części makroskopowych przełączników, jest krokiem w kierunku maszyn molekularnych.

For many people, the Arctic is not just a place to visit for various reasons, but actually their home. As such, polar research can study not only the importance of the Arctic and Antarctic for the world at large, but also what the world can do to help those who live and work there.

Nano-scale devices based on molecular machines could play a major role in the future of electronics, medicine and communications. Generating molecules with parts that can move like tiny "switches" is a step in the right direction.

The pace of climate change observed since the beginning of the industrial era has prompted scientists to seriously consider whether human activity is to blame for global warming. On the geological timescale, however, climate change is certainly nothing new or exceptional – as is clear when one looks at the record of plant and animal fossils.

We talk to Prof. Wiesław Bogdanowicz from the PAS Institute of Zoology about the origins, abilities and intelligence of feral dogs.

Will we ever harness the power of lightning? Probably yes, but first we need to answer some fundamental questions, because we've really just begun to tap into the secrets of atmospheric electricity.
