Researchers have engineered a way to create miniature, self-assembling blood vessel networks entirely from stem cells in the lab. These vascular organoids form functional vasculature when implanted in vivo and show therapeutic potential for restoring blood flow in ischemic tissues. We believe this work opens new opportunities for treating vascular diseases and advancing vascular biology research.

Researchers have successfully adapted a standardized system for analyzing facial expressions to include bonobos, our closest living relatives alongside chimpanzees. The study, led by an international team of scientists from multiple institutions including Leipzig University and the Max Planck Institute for Evolutionary Anthropology, extends the Chimpanzee Facial Action Coding System (ChimpFACS) to another species closely related to humans and chimpanzees, bonobos.

13 June 2025 / Kiel. Methods to enhance the ocean’s uptake of carbon dioxide (CO₂) are being explored to help tackle the climate crisis. However, some of these approaches could significantly exacerbate ocean deoxygenation. Their potential impact on marine oxygen must therefore be systematically considered when assessing their suitability. This is the conclusion of an international team of researchers led by Prof. Dr Andreas Oschlies from the GEOMAR Helmholtz Centre for Ocean Research Kiel. The findings were published yesterday in the journal Environmental Research Letters.
