The menstrual taboo persists. This is the main conclusion of a pioneering macro-study in Spain involving more than 4,000 participants and led by the INGENIO Institute, a joint centre of the Spanish National Research Council (CSIC) and the Universitat Politécnica de València (UPV). According to the analysis, 4 out of 10 people perceive menstruation as a topic that is still stigmatised.

Published on 17 November in the Journal of Applied Ecology, the research introduces a novel metric called “overlap intensity” which for the first time, measures not just the extent of shared space between penguins and fishing vessels, but how many penguins are actually affected by this overlap.

One person’s side effect could be another person’s treatment if we expand our perspective on small molecule drug targets, according to a new study published November 5, 2025, in npj Precision Oncology.

“Small molecules can have different targets and effects depending on the disease and cell type, and we can use this knowledge to repurpose more drugs to treat more patients,” said lead author Sanju Sinha, PhD, an assistant professor at Sanford Burnham Prebys.

Researchers from Stockholm University have – for the first time ever – managed to successfully isolate and sequence RNA molecules from Ice Age woolly mammoths. These RNA sequences are the oldest ever recovered and come from mammoth tissue preserved in the Siberian permafrost for nearly 40,000 years. The study, published in the journal Cell, shows that not only DNA and proteins, but also RNA, can be preserved for very long periods of time, and provide new insights into the biology of species that have long since become extinct.
