Thanks to supercomputing, the research was able to analyze the activity of 20,000 genes in more than one million cells with unprecedented resolution, revealing different aging dynamics between men and women, which will be key to achieving precision medicine.

This study highlights that many characteristics of immune system aging that were previously considered universal actually present specific dynamics according to biological sex.

When the option is to adapt or starve, animals are no stranger to getting scrappy in the face of climate change. Researchers conducted fieldwork in East Antarctica, where they revealed an underdocumented link in the food web of the Southern Ocean: Adélie penguins and their shelled pteropod consumption. Shelled pteropods, specifically Thecosomata, are a suborder of free-swimming sea snails. The study aimed to better understand Adélie penguin foraging behaviour and, in doing so, provided the first clear video evidence of Adélie penguins actively feeding upon shelled pteropods during their foraging sessions.

All processes such as wound healing, hair growth, and the replacement of old cells with new ones depend on cell division. During this process, chromosomes inside the cell must be evenly divided between two daughter cells. Even slight errors can lead to cellular abnormalities.

A research team at POSTECH (Pohang University of Science and Technology) has recently uncovered new clues suggesting that a protein called tau plays an important role in this highly regulated process. The findings were published in the international journal Nature Communications.

The International Society for Stem Cell Research (ISSCR) is pleased to announce the appointment of Hongmei Wang, Ph.D., as an Associate Editor of its journal, Stem Cell Reports. Dr. Wang is a professor of State Key Laboratory of Organ Regeneration and Reconstruction, Institute of Zoology (IOZ), Chinese Academy of Sciences (CAS).

‍An internationally recognized leader in developmental and reproductive biology, Dr. Wang brings deep expertise in early embryo and placental development, and advanced in vitro modeling systems. Her laboratory investigates the mechanisms that govern embryonic and placental development in non-human primates and humans, with the long-term goal of improving understanding of pregnancy health and exploring culture systems that support extra-uterine embryogenesis. Her work advances understanding of developmental diseases and holds potential for improving reproductive health outcomes.

A remarkable new discovery is shedding light on one of the greatest survival stories in Earth’s history, and answering a decades-old scientific mystery. Lystrosaurus, a hardy, plant-eating mammal ancestor, rose to prominence in the wake of the End-Permian Mass Extinction some 252 million years ago, the most devastating extinction event our planet has ever experienced. While countless species vanished, Lystrosaurus not only survived, but thrived in a world marked by extreme environmental instability, intense heat, and prolonged droughts.
