How gene expression noise shapes cell fate

Essential genes are often expressed with high variability during the development of cells. Scientists call this phenomenon "biological noise" and suspect that it is also decisive for the fate of cells, i.e. the developmental ...

Variability in the molecules of life

How variable are gene transcripts and proteins, the molecules of life, across the tissues and organs of the human body? Furthermore, how variable are they within the same tissue type from different people? Understanding this ...

How cells protect themselves from mitochondrial defects

Cells need powerhouses known as mitochondria to utilize the energy stored in our food. Most of the proteins required for this powerhouse function are encoded in the nucleus and transported into the mitochondria after they ...

How human brain development diverged from great apes

Researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, Institute of Molecular and Clinical Ophthalmology Basel, and ETH Zurich, Switzerland, have presented new insights into the development ...

How time affects the fate of stem cells

How do temporal variations in protein concentrations affect biology? It's a question that biologists have only recently begun to address, and the findings are increasingly showing that random temporal changes in the amount ...

Capturing extreme close-ups of cellular gene expression

Scientists studying genetic transcription are gaining new insights into a process that is fundamental to all life. Transcription is the first step in gene expression, the process taking place within all living cells by which ...
