The classic view of pain is that it protects by detecting and signaling the presence of harmful agents, but new research shows pain can shield the gut more directly. Experiments in mice show that activated pain neurons induce intestinal cells to release mucus that coats and protects the intestine both under normal conditions and during inflammation. The findings raise concerns about long-term use of certain medications that suppress protective pain signaling in conditions such as colitis and migraine.
Cleveland Clinic researchers have identified a common diabetes medication, metformin, as a possible treatment for atrial fibrillation. The study, published in Cell Reports Medicine, built on ongoing collaborative Cleveland Clinic research to support further investigation into metformin as a drug repurposing candidate. Researchers used advanced computation and genetic sequencing to determine that metformin’s targets overlap significantly with genes dysregulated in atrial fibrillation.
The most typical alterations in people with type 2 diabetes are insufficient secretion of insulin and reduced sensitivity to insulin in different organs.

UC San Diego researchers have for the first time discovered a pattern of DNA mutations that links bladder cancer to tobacco smoking. The work could help researchers identify what environmental factors, such as exposure to tobacco smoke and UV radiation, cause cancer in certain patients. It could also lead to more customized treatments for a patient’s specific cancer.
Scientists from St. Jude Children's Research Hospital identified the mechanism by which the disorder enhances the ability to discriminate between sounds as interneuron hyperexcitability in the auditory cortex.
Fat cells, or adipocytes, that grow in close proximity to breast cancers can shift into other cell types that promote tumor growth, a new study by UT Southwestern researchers suggests. The findings, published in Cell Reports, could lead to new ways to fight breast cancer, a disease that is diagnosed in more than 300,000 U.S. women each year and kills nearly 45,000 annually.
The genetic fingerprint of the sea anemone Nematostella vectensis shows that the members of this evolutionarily very old animal phylum use the same gene cascades for the differentiation of neuronal cell types as more complex organisms. These genes are also responsible for the balance of all cells in the organism throughout the anemone’s life. The results were published by a team of developmental biologists led by Ulrich Technau of the University of Vienna in "Cell Reports".
As the world gets warmer, the use of power-hungry air conditioning systems is projected to increase significantly, putting a strain on existing power grids and bypassing many locations with little or no reliable electric power.
