Scientists from Wrocław recreate ancient drug Theriac
Researchers from the Wrocław Medical University are the first in the world to have faithfully recreated Theriac, a medicinal hit in Europe from antiquity to the 18th century, consisting of 71 substances. It turns out that it was closer to a placebo than to the miraculous mixture that ancient medics believed it to be.

Too much light at night harms human health, say experts
Too much light at night not only interferes with astronomical observations and disrupts the behaviour of animals and plants, it can also threaten people, disrupting sleep, promoting obesity, depression and even cancer, said participants of the interdisciplinary seminar 'The Dark Side of Light - light pollution and its impact on our life'.

Global warming and other environmental changes drive antibiotic resistance
Antibiotics are considered one of the greatest achievements of 20th century medicine. Their introduction reduced mortality due to bacterial infections and contributed to the extension of life expectancy. However, the consequence of their mass use in humans and animals is the emergence and spread of strains resistant to these drugs. According to estimates, in 2019, 4.95 million people around the world died due to antibiotic resistance, including nearly a million children.

New concept explains link between vitamin D and ageing
How does vitamin D protect against the most common diseases and at the same time promote healthy ageing? The key to explaining the mechanism may be linking the body's individual response to vitamin D with immunocompetence (potent immunity).

Diet, microbiota and mental health are an ‘inseparable trinity’, says expert
‘Diet can support or negatively impact the gut microbiota. In the latter case, we will quickly notice symptoms not only in the digestive system, but also mental well-being,’ says Dr. Joanna Jurek, a biomedicine and human immunonutrition expert.

Dual strategy against 'castration-resistant' prostate cancer
Scientists intend to block a certain receptor in prostate cancer cells that is responsible for its growth. Known as 5-HT5AR, the receptors near the tumour increase the amount of serotonin, a neurotransmitter called the happiness hormone. However, serotonin also promotes the development of cancer and leads to metastases.

Polish scientists find curious relationship between biological clock genes, insulin and obesity
The biological clock helps regulate the timing of various processes that occur in the body. Diurnal variability is demonstrated, among others, by genes that regulate insulin sensitivity. Polish scientists have shown that the expression of biological clock genes in subcutaneous adipose tissue is linked to the action of insulin: it is lower in obese people than in those with normal body weight.
