1+ day, 3+ hour ago   (726+ words) Researchers at Carnegie Mellon University's School of Computer Science, the University of Pittsburgh School of Medicine and the University of Washington have uncovered a previously underexplored feature of Alzheimer's disease that may help scientists identify new avenues for treatment. To…...

6+ day, 16+ hour ago   (199+ words) A surprising immune system signal may help explain why zebrafish can regenerate damaged spinal cords so effectively. Researchers found that certain neutrophils release Il-4, which calms harmful inflammation and allows injured nerve fibers to grow again. Without these cells, healing stalled,…...

1+ week, 3+ day ago   (199+ words) Slow breathing with a prolonged exhale made people more willing to take risks by changing heart activity and increasing the brain’s sensitivity to rewards. The findings suggest that something as simple as controlling your breath can directly influence how you…...

1+ week, 5+ day ago   (768+ words) Persistent financial hardship may speed up age-related cognitive decline, according to new research led by University College London (UCL). Published in Innovation in Aging, the study analyzed information from 2,759 people in the UK who completed questionnaires across much of their…...

1+ week, 5+ day ago   (348+ words) Brain changes associated with Alzheimer’s may begin at least seven years before amyloid plaques become detectable with current PET scans. Researchers uncovered the signal by tracking healthy older adults with repeated brain imaging over nearly 20 years. The discovery could help…...

2+ week, 2+ day ago   (553+ words) Frequent micro-awakenings during sleep were linked to higher genetic risk for Alzheimer’s in healthy middle-aged adults who had no symptoms. The discovery raises the possibility that subtle changes during sleep could offer an early warning signal years before memory problems…...

2+ week, 5+ day ago   (201+ words) Early-life stress may physically alter how DNA is packaged in the brain, leaving stress-related genes primed to activate more easily years later. In mice, researchers were able to block this effect, preventing the heightened anxiety and stress sensitivity that otherwise…...

2+ week, 6+ day ago   (520+ words) A major study found that adults with depression show disrupted production of new neurons in the hippocampus, potentially weakening the brain’s ability to separate new experiences from painful memories. The researchers also identified broad molecular changes that could open the…...

3+ week, 1+ day ago   (827+ words) Millions of people carry APOE4, the strongest known genetic risk factor for Alzheimer's disease. New research suggests the gene variant may begin altering brain activity well before memory problems become noticeable. Researchers at Gladstone Institutes have now mapped out a molecular…...
