Researchers develop highly reactive RNA building blocks for enhanced chip production

An international research team led by the University of Vienna has succeeded in developing a new version of RNA building blocks with higher chemical reactivity and photosensitivity. This can significantly reduce the production time of RNA chips used in biotechnological and medical research. The chemical synthesis of these chips is now twice as fast and seven times more efficient. The results of the research were recently published in the prestigious journal Science Advances.

AI model predicts male infertility risk using blood hormone levels

According to a World Health Organization (WHO) study (2017), about half of all infertility is due to men. Semen analysis is considered essential for diagnosis of male infertility, but is not readily available at medical institutions other than those specializing in infertility treatment, and there is a high threshold for receiving it.
