1. Climate change and prehistoric human populations: Eastward shift of settlement areas at the end of the last ice age

   An archaeological study of human settlement during the Final Palaeolithic revealed that populations in Europe did not decrease homogenously during the last cold phase of the Ice Age. Significant variation in regional population sizes indicate differentiated reactions nested in an overall shift of settlement areas towards the east.

2. Researchers find intestinal immune cell prevents food allergies

   Researchers found that a small population of immune cells in the mouse intestine prevents allergic responses to food, suggesting that targeting such cells therapeutically could potentially lead to a new treatment for allergies.

3. New vaccine concept tackles harmful bacteria in the intestine

   In the fight against bacterial pathogens, researchers are combining vaccination with targeted colonization of the intestine by harmless microorganisms. This approach could potentially mark a turning point in the antibiotics crisis.

4. Cellular regulator of mRNA vaccine revealed... offering new therapeutic options

   A team of researchers has uncovered a key cellular mechanism that affects the function of mRNA vaccines and therapeutics. Their study provides the first comprehensive understanding of how mRNA vaccines are delivered, processed, and degraded within cells -- a breakthrough that could pave the way for more effective vaccines and RNA-based treatments.

5. Animal behavioral diversity at risk in the face of declining biodiversity

   Drastic declines in biodiversity due to human activities present risks to understanding animal behaviors such as tool use, according to new research. Shrinking animal populations make the study of these behaviors increasingly difficult, underscoring the urgency of targeted conservation efforts and inclusive conservation strategies. Action is needed not only for research, but also to respect our shared cultural heritage with animal species.
