Molecular motors direct the fate of stem cells

Scientists at the University of Groningen and the University Medical Center Groningen used molecular motors to manipulate the protein matrix on which bone marrow-derived mesenchymal stem cells are grown. Rotating motors altered ...

Molecular machine tears toxic protein clumps apart

How do cells disentangle proteins that are clumped together? Researchers from AMOLF in Amsterdam and Heidelberg University now show that the molecular chaperone ClpB can forcibly pull on exposed loops of protein chains, and ...

Understanding how cells defend their genome against invaders

Researchers at the University of Tokyo have uncovered more details about the tiny defenders that ensure fertility by protecting the genomes of specialized cells called germ cells, which produce eggs and sperm. The complex ...

Scientists discover how malaria parasites import sugar

The consumption of sugar is a fundamental source of fuel in most living organisms. In the malaria parasite Plasmodium falciparum, the uptake of glucose is essential to its life cycle. Like in other cells, sugar is transported ...
