Deep brain stimulation (DBS) of an area in the brain called the subcallosal cingulate (SCC) provides a robust antidepressant effect that is sustained over a long period of time in patients with treatment-resistant depression — the most severely depressed patients who have not responded to other treatments.
Read moreChemists have found that deliquescent minerals, which dissolve in water they absorb from humid air, can assist the construction of proteins from simpler building blocks during cycles timed to mimic day and night on the early Earth.
Read moreWhen it comes to repairing injured tissue, specialized cells in the body known as fibroblasts are called into action. Fibroblasts give rise to healing cells called myofibroblasts, which generally is good in the short term — but bad when myofibroblast activation gets out of hand. Now, researchers show how fibroblast activation and myofibroblast formation occurs, providing clues for how to target fibrosis — which impacts several chronic diseases.
Read moreBy scanning whole brains of Alzheimer's model mice from an early age, researchers were able to precisely trace the terrible march of amyloid plaques from deep brain structures outward along specific circuits. They also showed that plaque density in a key region in humans scales with disease stage.
Read moreNew research has found that a diet low in fermented carbohydrates has improved certain gut symptoms and improved health-related quality of life for sufferers of inflammatory bowel disease (IBD).
Read moreA team of biomedical engineers are developing a therapy which shows early indications it can protect neurons and stimulate the regrowth of blood vessels in damaged tissue.
Read moreResearchers have identified the gene mutation responsible for a form of night blindness in dogs. Strategies to treat this condition, which affects a layer of neurons just below the primary photoreceptor cells, could also inform treatment of other diseases that rely on targeting this cell type.
Read morePeople who increase their consumption of sugary beverages — whether they contain added or naturally occurring sugar — may face moderately higher risk of type 2 diabetes.
Read moreInterspecific feeding — when an adult of one species feeds the young of another — is rare among songbirds, and scientists could only speculate on why it occurs, but now, researchers have new insight into this behavior.
Read moreMaps identifying the areas suitable for establishment of the spotted lanternfly (SLF) in the United States and other countries have been published.
