Why can the human immune system often remember a vaccination for a whole lifetime? Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and Universitätsklinikum Erlangen have now investigated this question. Their study provides a surprisingly clear answer: The immune cells responsible for immunological memory seem to switch to a type of standby mode at an early stage. They can survive for many decades in this state. The findings have now been published in the journal Nature Immunology.

(WASHINGTON – Feb. 18, 2026) – Extreme endurance running damages red blood cells in ways that may affect their ability to function properly, according to a study published in the American Society of Hematology’s journal Blood Red Cells & Iron. Although the duration and long-term implications of the damage are unclear, the study adds to a growing body of evidence that extreme forms of exercise may harm, rather than support, overall health.

Seaweeds are versatile algae. They are sources of food, medicine, and many other products, and they have the added benefit of being extremely efficient at removing CO2 from the atmosphere as they grow.

However, seaweed aquaculture’s potential for sequestering carbon is overshadowed by the assumption that the biomass will be easily converted back into CO2, says UConn Department of Earth Sciences Assistant Professor Mojtaba Fakhraee. Fakhraee and co-author Noah Planavsky of Yale University argue this is not the case, and we need to reconsider the carbon removal potential of these dynamic systems. Their research is published in Nature Communications Sustainability.
