Biological Condensates Harbor Electrical Imbalances That Spark "Redox" Reactions

The human body relies heavily on electrical charges. Lightning-like pulses of energy fly through the brain and nerves and most biological processes depend on electrical ions traveling across the membranes of each cell in our body.

Metabolic Network Compatibility Not Likely the Limiting Factor in Prokaryotic Endosymbiosis

"One of the great mysteries of biology," says Eric Libby, former SFI Postdoctoral Fellow, now an associate professor at the Integrated Science Lab (IceLab), Umeå University in Sweden, "is eukaryogenesis, or how eukaryotes arose." Scientists consider this to be a period of major evolutionary transition, critical to our understanding of the history and evolution of life on Earth.

Artificial cells to serve as the powerhouse of the future

Chloroplasts and mitochondria are responsible for producing energy in nature, which is essential for creating sustainable, artificial cells in the lab. In addition to being “the powerhouses of the cell,” as the adage from middle school biology goes, mitochondria are also one of the most difficult intracellular components to artificially clone.

Researchers find methods to awaken and revive neural stem cells

Some areas of the adult brain contain quiescent, or dormant, neural stem cells that can potentially be reactivated to form new neurons. However, the transition from quiescence to proliferation is still poorly understood. A team led by scientists from the Universities of Geneva (UNIGE) and Lausanne (UNIL) has discovered the importance of cell metabolism in this process and identified how to wake up these neural stem cells and reactivate them. Biologists succeeded in increasing the number of new neurons in the brain of adult and even elderly mice. These results, promising for the treatment of neurodegenerative diseases, are to be discovered in the journal Science Advances.

Scientists discover two ways to preserve diseased upper motor neurons in ALS

Northwestern Medicine scientists have discovered two ways to preserve diseased upper motor neurons that would normally be destroyed in ALS, based on a study in mice. Upper motor neurons initiate movement, and they degenerate in ALS.
