CRISPRing the microbiome is just around the corner
To date, CRISPR enzymes have been used to edit the genomes of one type of cell at a time: They cut, delete or add genes to a specific kind of cell within a tissue or organ, for example, or to one kind of microbe growing in ...

How some tissues can 'breathe' without oxygen
Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells' mitochondria. Through a series of reactions called the electron transport chain, electrons are passed along in a sort ...

Bacteria and plants fight alike
A brown blotch on a plant leaf may be a sign that the plant's defenses are hard at work: When a plant is infected by a virus, fungus or bacterium, its immune response keeps the disease from spreading by killing the infected ...

The point of no return: Chromatin enforces cell fate decisions
Stem cells balance self-renewal with differentiation into mature cells. A fundamental and intriguing question is when during the process of maturation a cell reaches a "point of no return," losing its capacity to self-renew ...

Distortion: Researchers discover new strategy for antibodies to disable viruses
It is widely understood that antibodies neutralize viruses by latching onto their surfaces and blocking them from infecting host cells. But new research reveals that this barrier method isn't the only way that antibodies ...
