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.

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.

Researchers re-examine ancient crocodylomorph from Załęcze Wielkie
Scientists have re-examined the remains of a prehistoric marine reptile found in the 20th century in the village of Załęcze Wielkie (Łódź province). This distant relative of modern crocodiles was about four metres long and had a visible jaw injury, which it probably suffered in the first years of its life.
