Microcephaly is a congenital malformation that leads to a significantly reduced brain size and is often accompanied by developmental delay. An international research team led by Dr. Tran Tuoc from the Department of Human Genetics at Ruhr University Bochum, Germany, has discovered a previously unknown genetic cause for this condition. Mutations in the EXOSC10 gene – a central component of the RNA degradation complex (“exosome”) – cause primary microcephaly. The work was published in the journal BRAIN on October 24, 2025. 

A new study published in the scientific journal Oikos reveals for the first time the critical role polar bears play as carrion providers for Arctic species. Researchers from University of Manitoba and San Diego Zoo Wildlife Alliance, alongside researchers from Environment and Climate Change Canada, and the University of Alberta, have estimated that polar bears leave behind approximately 7.6 million kilograms of their prey annually, creating a massive and vital food source for a wide network of arctic scavenger species. 

This week, Tatta Bio, a scientific nonprofit advancing AI for genomics, has launched SeqHub — a platform helping scientists rapidly interpret proteins & genomes through AI-driven function prediction, context & structure.

Researchers are redefining the nutritional value of prey. Studying the dynamics of sea lion predators and their prey, the researchers found that not all prey are the same — even those of similar size and weight of the same species — offering new perspectives for understanding ocean food resources.
