Sociological shifts change expectations and behaviors of modern patients

Whereas patients in the past were expected to be patient, grateful, passive and docile - many of today's patients are assertive, demanding, impatient and insistent. So, what has happened?

PET microplastics remain in lungs and worsen respiratory tract inflammation

Microplastics (MP) are the subject of intensive medical research, but little is yet known about their effects on the immune system.

Study reveals right ventricle better tolerates oxygen loss during cardiac arrest

A study led by scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) provides new insights into ventricular fibrillation (VF), the most dangerous type of cardiac arrhythmia.

Scientists uncover shared gene signatures that reveal how mammals age

Researchers mapped more than 11,000 transcriptomes across mice, rats, macaques, and humans, revealing conserved molecular signatures of aging and mortality across tissues, species, and cell types. The study developed interpretable transcriptomic clocks that track age, mortality-related molecular change, chronic disease signals and responses to lifespan-altering interventions.

Experimental vaccine triggers broadly neutralizing HIV antibodies in macaques

For years, researchers have been hoping for vaccines that protect people against not just one strain of HIV, but every strain of the quickly mutating virus.

UCLA researchers identify brain circuit controlling memory organization

When a person has a new experience, their brain faces a subtle but critical decision: should this experience be categorized with other stored memories, or should it be filed away as its own new memory? Getting it right allows the brain to help people navigate the world.

Blood biomarkers may detect Alzheimer’s risk before symptoms appear

For the first time, researchers found blood biomarkers for Alzheimer's disease that correlated with minor cognitive differences in midlife adults who did not have dementia.

Gut changes linger years after polyp removal and may signal colorectal cancer risk

Researchers found that women who had undergone colorectal adenoma resection still showed gut microbiome and fecal metabolome alterations an average of about 12 years later. These persistent changes partly resembled colorectal cancer-associated patterns, suggesting that the host-microbiome axis may remain altered along the adenoma-cancer continuum.

AI maps how brain fluids move to clear waste

MR-AIV uses physics-informed AI and DCE-MRI scans to infer 3D brain-wide fluid movement in mice without direct flow measurements. The method distinguished slow diffusion-dominated transport from faster advective flow and estimated pressure and permeability patterns linked to brain waste clearance.

AI-powered atlas maps immune structures across multiple cancer types

In a new study published today in Science, researchers from The University of Texas MD Anderson Cancer Center developed a spatial atlas of specialized immune structures, called tertiary lymphoid structures (TLSs), across multiple cancer types.

Low protein intake linked to declining physical function with age

Researchers have found that consuming lower amounts of protein-rich foods may negatively affect physical functioning as people grow older, underscoring the vital function protein plays in preserving mobility and muscle strength in adulthood.

Brain transposons may influence aging and neurodegenerative disease progression

Transposable elements (TEs), also called transposons, are DNA sequences capable of moving or replicating from one location to another within a genome.

Study uncovers a biological link between chronic oral inflammation and female fertility

Chronic oral inflammation may impair female fertility by triggering a systemic immune response that affects the ovaries.

Scientists identify new therapeutic target for deadly prostate cancer

Researchers at Columbia University Irving Medical Center have identified a gene that drives the development of neuroendocrine prostate cancer (NEPC), an aggressive form of the disease.

New nutrient-sensing mechanism offers hope for neurodegenerative diseases

Researchers from the University of Cambridge highlight new ways that neurons and many cell types use to sense nutrients - opening potential novel therapeutic avenues for disorders such as Alzheimer's and Parkinson's disease.

Drug-filled nanofibers offer potential breakthrough treatment for brain cancer

Researchers with the University of Cincinnati and Johns Hopkins Medicine developed a potential treatment for brain cancer that uses nanofibers embedded with a combination of drugs that work in concert to target tumors.

‘Natural bypass’ of the heart helps doctors avoid risky cardiac surgeries

Your heart already has its own built-in bypass system that predicts whether the heart muscle is alive or dead - according to new research from the University of East Anglia and Norfolk and Norwich University Hospital.

Virtual AI mouse tests nanomedicine without using living animals

When a tumor manages to nestle itself in the brain of a living being, it has - from the tumor's perspective - done something particularly clever.

Vitamin deficiencies may contribute to chronic fatigue and low motivation

With less time and more work, chronic fatigue has become a moniker of modern society. However, this not only reduces the quality of life but also constitutes as a social issue that affects work efficiency and leads to accidents.
