Stem cell study paves way for manufacturing cultured meat

Scientists have for the first time obtained stem cells from livestock that grow under chemically defined conditions, paving the way for manufacturing cell cultured meat and breeding enhanced livestock.

Researchers call for standards for biological imaging

Stained molecules in the cell nucleus, the inner life of a synaptic cleft, or the surface of a floral leaf: Modern microscopes enable researchers to examine processes that are otherwise invisible and located in tiniest structures ...

Study reveals how bacterial pathogen adapts to nutritional stress

In order to cause disease, the human pathogen Staphylococcus aureus must adapt to the changing host environment. Many of these adaptations are mediated through two-component signal transduction systems (TCSs) that coordinate ...

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 ...

Wrangling an octopus-like viral replication machine

Endemic in Western African countries, Lassa virus is transmitted to humans through food or household items that are contaminated with the urine or feces of Mastomys rats. Even though many people who become infected with Lassa ...

Plant pathogen evades immune system by targeting the microbiome

A team of biologists has identified that the pathogenic fungus Verticillium dahliae, responsible for wilt disease in many crops, secretes an 'effector' molecule to target the microbiome of plants to promote infection. The ...

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 ...

Possible weakness found in neuroblastoma cells

The cells of a certain tumor type, neuroblastoma, divide very rapidly. This rapid division can have potentially fatal consequences for the cells. A new study shows how neuroblastoma cells deal with this dilemma.

Uncovering a promising use case for exosomes

Extracellular vesicles—or exosomes, as they are more commonly known—continue to be a curious research focus for the scientific community. Once assumed to be waste materials secreted by cells, exosomes have recently been ...

Getting the most therapeutic potential out of cells

A simple change in the way donor cells are processed can maximize a single cell's production of extracellular vesicles, which are small nanoparticles naturally secreted by cells, according to new research from researchers ...
