Summary: Researchers at the University of Massachusetts Amherst have launched two large-scale longitudinal studies to investigate how napping supports brain development and memory in infants and preschoolers. By tracking changes in the hippocampus—the brain region crucial for short-term memory—these studies aim to clarify when and why young children need naps and how naps influence memory … Read more

Protein aggregates in the cytoplasm disrupt essential transport between nucleus and cytoplasm In brains affected by neurodegenerative disorders, researchers commonly observe deposits of misfolded proteins, often referred to as protein aggregates. These deposits are a hallmark of illnesses such as Alzheimer’s, Parkinson’s, Huntington’s disease, and amyotrophic lateral sclerosis (ALS). While the presence of aggregates has … Read more

Summary: New research indicates that ultra-wide field retinal imaging may offer a reliable, noninvasive way to monitor neurodegenerative disease progression, including Alzheimer’s disease (AD). The study found increased drusen and distinct vascular changes in the peripheral retina of AD patients. Source: Queen’s University Belfast. Researchers at Queen’s University Belfast report for the first time that … Read more

Summary: New CT scans of the Thescelosaurus neglectus specimen known as “Willo” reveal sensory adaptations that suggest this small herbivore may have spent part of its life underground. These findings challenge the dinosaur’s previously dull reputation and offer fresh insight into dinosaur ecology and behavior. High-resolution CT imaging shows Willo had a restricted hearing range … Read more

New research from Wake Forest Baptist Medical Center finds that suicide, while strongly associated with psychiatric conditions, also correlates with environmental pollution. A new ecological study led by John G. Spangler, M.D., M.P.H., a professor of family medicine at Wake Forest Baptist Medical Center, examined the relationship between air pollution—specifically emissions from coal-fired power plants—and … Read more

Summary: New findings point to potential drug-based strategies to stimulate generation of specific brain cell types and support repair in degenerative conditions. Source: PLOS Overview Researchers have identified existing small-molecule drugs that engage signaling pathways guiding neural stem cells to become particular adult brain cell types in mice. Published 28 March in the open-access journal … Read more

Green Tea Steeped in Bottled Water Has More Antioxidants, Cornell Study Finds Summary: Researchers report a boost in beneficial antioxidants when green tea is brewed with bottled water rather than tap water. Source: Cornell University. Key finding: Green tea brewed with bottled water contains higher levels of the antioxidant epigallocatechin gallate (EGCG) than green tea … Read more

Flu vaccination linked to a substantial short-term reduction in stroke risk, new study finds A major study from the University of Lincoln, funded by the National Institute for Health Research and published in the journal Vaccine, found that receiving an influenza (flu) vaccine was associated with a significantly lower risk of suffering a first stroke … Read more

Summary: Researchers report that certain fat molecules help trigger a cellular stress response that can protect against neurodegenerative diseases such as Huntington’s, Parkinson’s, and Alzheimer’s. Source: UC Berkeley A newly discovered stress-response pathway uses specific lipids to support cellular health Researchers at the University of California, Berkeley, have identified a surprising link between lipid metabolism … Read more

Summary: A new multimodal study identifies a nutrient profile linked with slower brain aging in cognitively healthy older adults. By combining blood biomarker analysis, brain imaging, and cognitive testing, researchers found that a pattern of fatty acids, antioxidants, carotenoids, vitamin E, and choline—nutrients common in the Mediterranean diet—correlates with better cognitive performance and preserved brain … Read more
