Study reveals why US life expectancy gains stalled after decades of progress

A PNAS study analyzing US mortality from 1979 to 2023 reveals that life expectancy stagnation reflects both worsening outcomes in post-1950 birth cohorts and a broad mortality deterioration beginning around 2010. Cardiovascular mortality slowdowns, rising external causes, and cohort-specific patterns help explain the persistent decline in longevity gains.

Immune cells found to actively promote plaque formation in Alzheimer’s disease

A new study led by researchers from VIB and KU Leuven shows that immune cells called microglia can actively promote the formation of plaques in Alzheimer's disease, challenging the long-standing view that these cells serve only as defenders against plaque buildup.

Mapping the evolution of AI in organelle segmentation

In organelle imaging, segmentation aims to accurately delineate pixels or voxels corresponding to target organelles from background, noise, and other cellular structures in microscopy images, thereby generating masks suitable for quantitative analysis. Robust segmentation is foundational to downstream quantification, including morphological characterization, spatial distribution analysis, temporal trajectory tracking, and the detection of key biological events.

Using engineered bacteria to breach tumor defenses

Baylor University researchers have published a novel approach to fight colorectal cancer, using modified bacteria as a courier to deliver potent cancer-killing proteins into tumor cells. Michael S. VanNieuwenhze, Ph.D., FRSC, University Distinguished Professor and chair of the Department of Biology, along with Baylor doctoral students and a colleague at Texas Tech University Health Sciences Center, published their promising research in Cell Chemical Biology.

Hormonal imbalance and gut microbes linked to cognitive deficits in patients with PitNETs

Pituitary neuroendocrine tumors (PitNETs) are commonly associated with visual disturbances and endocrine abnormalities; however, many patients also experience cognitive deficits, particularly in memory, attention, and executive function, which significantly affect quality of life.

Frequent phone checking linked to weaker attention in middle and high school students

A new study from researchers at University of North Carolina at Chapel Hill finds that middle and high school students spend nearly one-third of the school day on their smartphones, checking them dozens of times, often for social media and entertainment, with frequent checking linked to weaker attention and impulse control.

EVA1A regulates fatty acid transporter CD36 in fatty liver disease

Metabolic Dysfunction-Associated Steatotic Liver Disease（MASLD） is characterized by excessive accumulation of lipids in hepatocytes and is closely associated with the rapid rise in insulin resistance, obesity, and diabetes prevalence, making it one of the most common chronic liver diseases worldwide.
