Inauguration of an eco-factory
Special antimicrobial coating effective against many pathogens
For playing card producer Fabryka Kart Trefl-Kraków, 2020 was one of the most important and most groundbreaking years in the company s history â one which extends back more than seven decades.

A new analysis of heavy-ion collision experiments uncovers evidence that two colliding nuclei behave like a Josephson junction a device in which Cooper pairs tunnel through a barrier between two superfluids.
Figure 1: (Top) Sketch of a Josephson junction, in which Cooper pairs tunnel through a barrier (green) between two superconductors (blue). In the ac Josephson effect, an applied dc voltage produces an oscillating, or ac, current, leading to the emission of microwave photons. (Bottom) Potel and co-workers have shown that a similar description applies to colliding nuclei [4]. As the nuclei approach, neutron pairs tunnel back and forth between them, causing the emission of gamma-ray photons.(Top) Sketch of a Josephson junction, in which Cooper pairs tunnel through a barrier (green) between two superconductors (blue). In the ac Jos
A group of scientists from the Warsaw University of Technology is ready to test their COVID-19 vaccine on animals but testing would depend on finding a bigger partner with the necessary resources.
There is still a sufficient amount of funds for animal testing, however, the next stages, including human testing, will not be possible without financial support, explained the leader of the team of scientists working on the vaccine, Professor Tomasz Ciach of Warsaw University.
There is still room for new vaccines on the market, Ciach added, pointing to the shortages of vaccines that are produced abroad.
According to Ciach, developing a vaccine at a national level is even more important due to possible future new waves of the virus. “It may turn out – as is in the case of the flu – that vaccines will have to be renewed every once in a while. Constant access to our own vaccine will then be a huge safeguard and help protect us,” he said.

A Finnish nurse has made headlines by appearing to disprove pharmaceutical company Pfizer wrong with regards to its estimate that every vial of the COVID-19 vaccine is enough for five jabs, by demonstrating that seven people can be vaccinated using one vial. Read more.

Flemish health minister rejects calls to prioritise youngsters in vaccination. A group of about 40 people from various sectors in Flanders have written a letter asking for young people between 16-25 years to be considered an “essential” group and be given priority in Belgium’s vaccination campaign. Flemish Minister of Health Wouter Beke rejected the idea. Read more.
