Antidepressant fluoxetine alters brain energy use and boosts neural plasticity

A new study shows that the widely used antidepressant fluoxetine does more than boost serotonin levels: it changes how brain cells manage their energy and rebuild their connections, potentially helping the brain "loosen up" and adapt during depression treatment.

Lysosomal activity in worms linked to transgenerational extension of lifespan

In the Wang Lab, it's not unusual for worms to live for a long time. HHMI Janelia Research Campus Senior Group Leader Meng Wang and her team study longevity. They've shown that by overexpressing an enzyme in the lysosomes of the roundworm C. elegans, they can extend the worm's life by up to 60 percent.

Study explains how genetics and lifestyle combined to keep a 117-year-old healthy

Scientists conducted a multiomics study of the world’s oldest verified person (117 years), uncovering protective genetic, immune, metabolic, microbiome, and epigenetic traits that supported her exceptional longevity. These findings highlight how aging and disease may, under rare circumstances, be decoupled.

UdeM studies make a major breakthrough in predicting neurodegenerative diseases

An international research team led by Université de Montréal medical professor Shady Rahayel has made a major breakthrough in predicting neurodegenerative diseases.

Organophosphate pesticide exposure linked to reduced sperm quality in healthy men

This pilot study found that urinary metabolites of organophosphate pesticides were linked to reduced sperm motility in healthy young men, though results were preliminary. Oxidative stress did not explain the association, suggesting other biological pathways may be involved.

Mount Sinai study maps protein networks driving Alzheimer’s disease pathogenesis

A new study led by the Icahn School of Medicine at Mount Sinai offers one of the most comprehensive views yet of how brain cells interact in Alzheimer's disease, mapping protein networks that reveal communication failures and point to new therapeutic opportunities.

Study uncovers how lymphatic endothelial cells assist in generating robust immune memory

A study published today in Nature Communications describes how lymphatic endothelial cells assist in generating robust immune memory, offering new insights into how the immune system functions.

Tiny DNA junctions provide feedback to control genetic crossovers

Every new life begins after a genetic shuffle. When organisms make eggs or sperm, maternal and paternal chromosomes pair up and swap pieces of DNA in a process called crossing over.

UPR modulators show promise in treating cancer-related bone disease

Before a chain of amino acids can become an active and useful protein, it must be processed and folded into the appropriate conformation.

Targeting TGF-β signaling as a strategy to treat liver fibrosis

Liver fibrosis, a pathological scarring process resulting from chronic liver injury, represents a significant global health burden due to its potential progression to cirrhosis and hepatocellular carcinoma.

Genetic modification enhances "living drugs" for blood cancers

CAR T cells are patient-derived, genetically engineered immune cells. They are "living drugs" and constitute a milestone in modern medicine. Equipping T cells, a key cell type of the immune system, with a "chimeric antigen receptor" (CAR) enables them to specifically recognize and attack cancer cells.

Study shows dementia patients exposed to pollution had longer telomeres

Researchers studying a Swedish aging cohort found no overall link between air pollution and telomere shortening, a key marker of biological aging. Intriguingly, dementia patients exposed to higher pollution showed longer telomeres, though results were statistically non-significant.

Researchers uncover how chromosome crossovers protect fertility

When a woman becomes pregnant, the outcome of that pregnancy depends on many things - including a crucial event that happened while she was still growing inside her own mother's womb.

Influenza infection in pregnant mice linked to fetal brain exposure

A new study from the University of Illinois Urbana-Champaign shows, for the first time, that severe flu infection in pregnant mice leads to a breakdown in placental and brain barriers, leading to the accumulation of potentially harmful molecules in the fetal brain.

New study reveals silent onset of rheumatoid arthritis

Scientists have discovered that rheumatoid arthritis (RA) doesn't start when the pain begins. It silently starts years earlier.

Stem cell treatment could help millions of people with end-stage kidney disease

More than 4 million people worldwide have end-stage kidney disease that requires hemodialysis, a treatment in which a machine filters waste from the blood.

Loss of Trp53 gene affects immune responses in ovarian cancer

A new research paper was published in Volume 16 of Oncotarget on September 22, 2025, titled "Loss of Trp53 results in a hypoactive T cell phenotype accompanied by reduced pro-inflammatory signaling in a syngeneic orthotopic mouse model of ovarian high-grade serous carcinoma."
