In 2004, construction workers in Norwich, UK, unearthed human skeletal remains that led to a historical mystery -- at least 17 bodies at the bottom of a medieval well. Using archeological records, historical documents, and ancient DNA, British researchers have now identified the individuals to be a group of Ashkenazi Jews who may have fallen victim to antisemitic violence during the 12th century. Their findings shed new light on Jewish medical history in Europe.

Researchers explore how human tissue models can be used to examine the impact of heart attacks and treatment of the fibrotic tissue outside the body, improving treatment and diagnosis. They use organoids, 3D organlike multicellular models derived from stem cells, to mimic natural development, structural organization, regeneration, and disease progression. Meanwhile, microfluidic devices control cell placement and fluid flow to act like the heart on a chip, while bioprinting allows cardiac tissue to be built up layer by layer.

A growing body of research suggests that the disease may also flow from defects in glia, important support cells found in the brain. The new study expands our understanding of the underlying mechanisms of the disease, and reinforces the potential of therapies that target glia cells.

Preeclampsia is a condition that affects the placenta during pregnancy and is dangerous for both the fetus and the mother. Scientists have proposed a new therapy, tested in two rodent models, that corrects the defects identified in placental cells, and restores placental and fetal weight. The treatment successfully lowers blood pressure in the mother and resolves the characteristic preeclampsia symptoms of excess protein in urine and cardiovascular abnormalities.

Researchers develop a method to identify aortic valve dysfunction using complex network analysis that is accurate, simple to use, and low-cost. They used heart sound data to create a complex network of connected points, which was split into sections, and each part was represented with a node. If the sound in two portions was similar, a line was drawn between them. In a healthy heart, the graph showed two distinct clusters of points, with many nodes unconnected. A heart with aortic stenosis contained many more correlations and edges.

Researchers working on developing oral insulin tablets as a replacement for daily insulin injections have made a game-changing discovery. The researchers have discovered that insulin from the latest version of their oral tablets is absorbed by rats in the same way that injected insulin is.
