Flexible knots and links in particles under better control
Researchers from the University of Warsaw and the University of Wrocław have developed a method for constructing flexible molecular knots and links. Flexibility enables the formation of entangled regions in protein or nucleic acid molecules.

Study: COVID-19 may have reached Europe before December 2019
There are indications that infections caused by SARS-CoV-2 appeared in Europe before the official start date of the pandemic, i.e. before the turn of 2020. This is evidenced by Polish research on the occurrence of excess mortality in over 900 regions of the continent in 2019.

Social position linked to health, Polish-Norwegian study shows
Subjectively perceived social position is strongly related to health. The lower you assess your social status, the higher the risk of developing various diseases and the risk of death from various causes, a researcher from the University of Warsaw says.

Scientific work is for the persistent, says brain researcher
‘There are successes in a scientist's work, but there are dozens of failures along the way. As much as 70-80 percent of our work ends in failure. However, a successful experiment is the greatest motivation for further work,’ says Dr. Aleksandra Rutkowska, who studies the nervous system, especially the degeneration processes taking place in the brain.

Software to support neurosurgeons in aneurysm treatment
Aneurysms of various shapes and sizes, previously imaged in patients, will be virtually 'operated on' in many possible ways. This will lead to the creation of software that will help neurosurgeons secure them against breaking and growing.

Biomaterial injection to accelerate bone healing
A Polish scientist is working on a nanofibre biomaterial that can be injected directly into the fracture site. Ultimately, it will help patients whose bones heal too slowly or when this process is hampered by problems related to osteoporosis, among other things.

Winter activity particularly good for your health, say scientists
Physical activity in winter supports the body's physiological defence mechanism against cold. It causes increased metabolism and stimulates the circulatory system, say scientists who have examined the impact of winter activity on somatic parameters, body composition and motor skills of men.
