The recipient was the head of the team of surgeons and the Oncological and Reconstructive Surgery Clinic in the Gliwice branch of the National Cancer Institute, Professor Adam Maciejewski.

- The European Solar Orbiter probe intended for solar research launched from Cape Canaveral in Florida (USA). The first useful data are expected in 2021. Solar Orbiter will get closer to the Sun than was previously possible and study the Sun's poles, which are hardly visible from Earth, providing new data about our star and heliosphere.

- Genetic information from prehistoric proteins was obtained from remains dated at 800,000 years. They concern one of our prehistoric cousins and will help organize the human evolutionary tree, scientists reported in Nature.

Until now, experts assumed that the Universe was expanding at the same rate in every direction.

- An important discovery by Polish scientists: photosynthesis is driven not only by light, but also by heat. Until now, it was thought that plants use only light quanta in photosynthesis. A team from the Maria Curie-Skłodowska University and the Institute of Agrophysics of the Polish Academy of Sciences in Lublin identified an additional mechanism: photosynthesis also requires thermal energy. The results were published in the Journal of Physical Chemistry Letters.
- The structures of the human brain responsible for processing language began to form at least 25 million years ago in distant human ancestors, scientists reported in Nature Neuroscience. This means that they are 20 million years older than previously thought. They had evolved long before Homo sapiens appeared.

- In helium cooled to almost absolute zero, scientists for the first time observed an interaction between two time crystals - ones that have a repetitive structure not only in space but also in time. The discovery could have important practical applications, e.g. in quantum information processing. Time crystals, also known as space-time crystals, are a novelty. The Nobel Prize winner Frank Wilczek predicted their existence only in 2012, and the first such crystals were observed in 2016.

- Research showed that Poland was home to the oldest remains of Neanderthals in Central Europe. In 2008, tools and remains of Neanderthals, our extinct evolutionary relatives were discovered in Stajnia Cave (Mirów, Silesia). These were the first Neanderthal remains discovered in Poland. Originally dated to approx. 52-42 thousand years ago, they turned out to be much older, scientists reported in Scientific Reports.

- Our immediate ancestors, people anatomically like us, reached the western parts of Europe 5,000 years earlier than previously thought. It could be 41,000-38,000. years ago. This means that they lived in this area with the Neanderthals, our extinct relatives. A publication on the subject appeared in Proceedings of the National Academy of Sciences.
- A 215-million-year-old jaw fragment with two double-rooted teeth, which belonged to a previously unknown shrew-like mammaliaform, measures barely 2 cm. Polish palaeontologists reported on the oldest find of this type in PNAS. The small fragment of the lower jaw was discovered in 2014 in eastern Greenland by Dr. Grzegorz Niedźwiecki from the University of Uppsala (Sweden). It took several years to analyse the find.

Górski from the University of Warsaw and NASA Jet Propulsion Laboratory, California Institute of Technology (Caltech) and Professor Romuald Schild from the Institute of Archaeology and Ethnology of the Polish Academy of Sciences in Warsaw.
- The Vega rocket with two satellites, including one co-created by Space Research Centre PAS (Taranis), was launched from the Guiana Space Centre near Kourou in French Guiana. However, exactly eight minutes after the rocket launched, it lost speed and changed its trajectory. Taranis' task was to investigate the mysterious high-energy TLE flares.
- A new version of the data on the detection of phosphine in Venus clouds was released. The discovery became famous in September, but in the following weeks there was a lot of controversy about its correctness. The criticism concerned several matters. The released spectral line of phosphine was very faint, at the  noise level. It is usually assumed that in order to reliably confirm the existence of a compound in space, it is necessary to observe more than one of its spectral lines. Other scientists made infrared observations (where phosphine should also have spectral lines) and found no signs of the compound on Venus. The way the data was processed was also questioned. Other arguments indicated that if the line was real, it had been misidentified.
- Professor Piotr Stepnowski was elected Rector of the University of Gdańsk for the years 2020-2024. The election was announced after the resignation of Dr. Jerzy Gwizdała.

- Professor Marcin Król died. He was an outstanding historian of ideas, long-term lecturer at the University of Warsaw, activist of the democratic opposition in the People's Republic of Poland and a publicist.
- The most comprehensive and extensive list of known plant species was compiled. It contains 1,315,562 different vascular plants, which means an increase in their number by about 70,000. (approx. 20%) compared to the previous list. The authors also managed to add 181,000 previously unknown species. The lead author is Dr. Martin Freiberg from the Botanical Garden of the University of Leipzig.
- A 300 m radio telescope at the Arecibo Observatory was destroyed. It served astronomy and space research for 57 years, it was with this radio telescope that Aleksander Wolszczan discovered the first extrasolar planetary system. The Arecibo Observatory telescope also appeared in culture, including the 1997 film Contact, the 1995 film Species, a Bond film (GoldenEye, 1995), and in an episode of X-Files.
- The Ministry of Science presented its academic freedom package, a draft amendment to the Law on Higher Education and Science. The package introduces legal changes to guarantee teachers freedom of teaching, freedom of speech and freedom of research.
