A new electronic implant system can help lab-grown pancreatic cells mature and function properly, potentially providing a basis for novel, cell-based therapies for diabetes. The approach, developed by researchers at the Perelman School of Medicine at the University of Pennsylvania and the School of Engineering and Applied Sciences at Harvard University, incorporates an ultrathin mesh of conductive wires into growing pancreatic tissue, according to a study published in Science.

Now, researchers from the University of Southern Denmark and Odense University Hospital have discovered a previously undescribed virus in a common gut bacterium. The virus appears more frequently in patients with colorectal cancer. The study is published in the journal Communications Medicine.

Researchers at Washington University School of Medicine in St. Louis have developed a method to predict when someone is likely to develop symptoms of Alzheimer’s disease using a single blood test. In a study published in Nature Medicine, the researchers demonstrated that their models predicted the onset of Alzheimer’s symptoms within a margin of three to four years.
