The human brain is not a fast-healing organ. Normally it doesn’t need to be as adult brain cells are stable and last for a lifetime. When trauma or disease such as a stroke occurs, the brain struggles to bounce back because it has a limited ability to regenerate lost cells.
Stem cell therapy is a promising method for boosting regeneration in the brain, but transplanted cells have struggled to replace damaged tissue and reestablish broken circuits. In a new study of a therapy derived from human stem cells and transplanted into mice, the cells matured, integrated into existing circuits and restored function. By tracing the cells and sequencing their gene expression patterns, the researchers also revealed how transplanted cells find where they need to go and form connections with the nervous system.A commentary coauthored by IIASA experts and senior representatives from the UN and the international statistics community discusses the implications of recent changes to the Demographic and Health Surveys (DHS) program and highlights the importance of integrating citizen science more fully into official data systems.
The amount of litter floating in the Rhine is many times larger than previously believed. Researchers from the University of Bonn, the University of Tübingen and the Federal Institute of Hydrology (BfG) partnered with the Cologne-based non-profit pollution-fighting organization K.R.A.K.E. to collect and classify macro litter in a floating litter trap—the only one of its kind in Germany—over a period of 16 months. Extrapolation models based on the observed volume indicate that roughly 53,000 items of macro waste debris float past Cologne on the Rhine river every day. Disposable plastic products make up a large proportion of the litter found in the Rhine. The findings have now been published in the scientific journal “Communications Sustainability.”
A new study highlights a semi-transparent, color-tunable solar cell designed to work in places traditional panels can’t, like windows and flexible surfaces. Using a 3D-printed pillar structure, the researchers can fine-tune how much light passes through and what color the cell appears, without changing the solar material itself. The result is a system that balances energy output with durability, while giving designers far more control over how the technology looks and functions.
