Body: Alzheimer's disease is the main cause of dementia and current therapeutic strategies cannot prevent, slow down or cure the pathology. The disease is characterized by memory loss, caused by the degeneration and death of neuronal cells in several regions of the brain, including the hippocampus. Researchers have identified a small molecule that can be used to rejuvenate the brain and counteract the memory loss.

Body: Biologists have used human pluripotent stem cells to grow sesame-seed-sized heart models, called cardioids, that spontaneously self-organize to develop a hollow chamber without the need of experimental scaffolds. This advance allows for the creation of some of the most realistic heart organoids to date.

Body: Researchers have found a way to study uterine fluid in the lab, thereby avoiding invasive procedures during pregnancy, while at the same time developing a potential model for using precision medicine to improve pregnancy outcomes.

Body: An investigational gene therapy can safely restore the immune systems of infants and children who have a rare, life-threatening inherited immunodeficiency disorder, according to new research. The researchers found that 48 of 50 children who received the gene therapy retained their replenished immune system function two to three years later and did not require additional treatments for their condition, known as ADA-SCID.

Body: A team of researchers has developed a molecular catalog of cells in healthy lungs and the lungs of people with cystic fibrosis.

Body: Stem cells have the ability to turn into different types of cell. Now scientists have developed a method to organize lab-grown stem cells into an accurate model of the first stage of human embryo development.

Body: Researchers have discovered a key molecule that allows cancer stem cells to bypass the body's natural immune defenses, spurring the growth and spread of head and neck squamous cell cancers. Their study, conducted in mice, also demonstrates that inhibiting this molecule derails cancer progression and helps eliminate these stem cells.

Body: Despite the prevalence of Alzheimer's, there are still no treatments, in part because it has been challenging to study how the disease develops. Now, scientists have uncovered new insights into what goes awry during Alzheimer's by growing neurons that resemble -- more accurately than ever before -- brain cells in older patients. And like patients themselves, the afflicted neurons appear to lose their cellular identity.

Body: Researchers have mapped the first complete atlas of single cells that make up the human teeth. Their research shows that the composition of human dental pulp and periodontium vary greatly. Their findings open up new avenues for cell-based dental therapeutic approaches.

Body: People with type 2 diabetes tend to have poorer muscle function than others. Now a research team has discovered that in type 2 diabetes, a specific gene is of great importance for the ability of muscle stem cells to create new mature muscle cells.
