Using stem cells and a bioreactor, researchers generated living embryos that survived for more than a week and began to develop internal organs.

Nanoparticle-coated bacteria can capture tumor antigens and deliver them to immune cells, triggering a response that improved survival rates in mice.

Nanoparticle-coated bacteria carry cancer-derived proteins to dendritic cells, enabling the immune system to launch a response in a mouse model.

Nearly all mouse sperm have hooks on their heads. But new research suggests the structures slow them down—so what exactly is their purpose?

A new technique reveals cells’ precise locations and functions in the brain. Its developers have already used it to identify a previously unknown neuron type.

A new methodology combines existing techniques to reveal the specific function and location of multiple types of neurons at once.

A study that transfused plasma from active to inactive mice suggests the protein clusterin enhances cognition.

Abnormal sympathetic neuron growth leads to simultaneous activation of clusters of sensory neurons, causing the difficult-to-treat sensation.

Researchers say they hope to launch a clinical trial to test bumetanide, a diuretic approved in 2002, but how it might improve neural functioning is unclear.

While exploring suspended animation in mice, scientists discover how an enzyme can protect the brain from dangerously low levels of oxygen.

Researchers have identified specific cells and neuropeptides involved in mediating the sneeze response in mice exposed to allergens or chemical irritants such as capsaicin.

A mouse study identifies the brain regions and specific signaling factors that regulate the sneeze response.

In both a mouse model and the hospital records of more than 3 million children, researchers found a connection between strong immune activation in males and later symptoms of autism spectrum disorder.

Shoring up the tissues that separate neurons and other brain cells from the circulatory system in fruit flies and mice can prolong life in the presence of a tumor.

RNA-DNA complexes that were modified with cholesterol made it into the brains of rats and mice, where they knocked down target genes.

A long noncoding RNA from humans appeared to help the enzyme phenylalanine hydroxylase work better in a mouse model of phenylketonuria, the disorder characterized by reduced activity of that enzyme.

The microbiota helps align a mouse’s innate immune system with its feeding patterns, prepping the animal to fend off infection when it’s most likely to be eating.

Targeted cancer therapy may jeopardize the effectiveness of subsequent immunotherapy by reducing dendritic cell numbers and activation, according to study of mice and patient samples.

Researchers are using experiments and observational studies to look for host genetic variation that could be partly determined by the gut microbiota.
