(Phys.org) —Last month, researchers reported the creation of the first primitive brain-like structures made from human stem cells. To create the complex morphology of these cerebral organoids, cells within a proliferating ...
Using a simple glass capillary, atomic physicists at RIKEN are developing an ultra-narrow ion beam that pinpoints a part of organelles in a living cell, enabling biologists to visualize how the damage affects cell activities.

(Phys.org)—Two teams of researchers taking different approaches have successfully mapped and diagramed the nuclear pore complex (NPC)—protein complexes that make up the pores in the nuclear envelope that allow or prevent ...
Viruses are tiny packets of destruction and there are more of them than any other biological entity on the planet.
