Junk' DNA may hold new clues to Alzheimer’s disease

When most of us think of DNA, we have a vague idea it's made up of genes that give us our physical features, our behavioral quirks, and keep our cells and organs running.

Genetic differences can affect the effectiveness of antibody therapies

The genome differs from person to person in thousands of positions. In some cases, this means that proteins have a different building block in certain regions, rendering some antibody-based therapies ineffective, report researchers from the University of Basel, Switzerland.

SARS-CoV-2 manipulates host cell's RNA to weaken the immune response

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes COVID-19, uses a sophisticated tactic to evade the human body's defense system.

Researchers uncover how a gene influences cell size across various cell types

What keeps our cells the right size? Scientists have long puzzled over this fundamental question, since cells that are too large or too small are linked to many diseases. Until now, the genetic basis behind cell size has largely been a mystery.

Urine-based microRNA clock predicts biological aging without a blood test

Researchers developed and validated a non-invasive urinary microRNA aging clock using extracellular vesicle miRNAs from more than 6,000 adults. The model predicts age with about 4 to 5 years error and links accelerated aging signals to type 2 diabetes.

Pathology AI models show demographic bias in cancer diagnosis

Pathology has long been the cornerstone of cancer diagnosis and treatment. A pathologist carefully examines an ultrathin slice of human tissue under a microscope for clues that indicate the presence, type, and stage of cancer.

SARS-CoV-2 evolves after jumping from humans to zoo animals

Research on SARS-CoV-2 in zoo tigers, lions, and hyenas shows rapid viral evolution and adaptation, offering insights into cross-species transmission dynamics.

GDF3 protein sustains harmful inflammation in aging immune cells

As people age, their bodies develop a dysfunctional immune system, which can leave older adults more susceptible to conditions like sepsis.

Chemotherapy may reduce HIV-infected T cells

Advancements in HIV/AIDS research, drug development and clinical practice since the 1980s have made it possible for people living with HIV to lead long, productive lives and keep the virus in check at undetectable levels and nontransmissible as long as therapy is maintained.

New research reveals the impact of DNA-histone cross-links on genome stability

DNA–protein cross-links (DPCs) represent a severe form of DNA damage that can disrupt essential chromatin-based processes. Among them, DNA–histone cross-links (DHCs) occur frequently within nucleosomes, yet their structural and functional consequences remain poorly understood due to their instability and low natural abundance.

Virus shells use asymmetry to control RNA release and infection

Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, but new research led by scientists at Penn State reveals a deliberate imbalance in their shape that helps them infect their hosts.

Researchers identify chromatin accessibility changes driving stem cell transformation in MDS

Over the past few decades, advances in hematology have illuminated how a delicate balance between stem cell self-renewal and differentiation sustains healthy blood formation.

Massive genetics study shows what truly separates and unites 14 psychiatric disorders

This large-scale genomic analysis of 14 psychiatric disorders shows that most heritable risk is shared across five broad genetic factors, with only limited disorder-specific variation. The study maps where risks converge or diverge biologically, revealing distinct cell type signatures and developmental pathways that may guide future diagnostic and therapeutic frameworks.

Researchers discover the enzyme responsible for chromothripsis in cancer

University of California San Diego researchers have discovered the enzyme responsible for chromothripsis, a process in which a single chromosome is shattered into pieces and rearranged in a scrambled order, allowing cancer cells to rapidly evolve and become resistant to treatment.

Shared genetic roots of 14 psychiatric disorders revealed

Researchers from the Psychiatric Genomics Consortium (PGC) report that most genetic influences on mental illness are shared across diagnostic categories, revealing a more interconnected biological landscape than traditional classifications suggest.

Disrupted genome architecture drives lymphoma development

Cancer isn't just about broken genes-it's about broken architecture. Imagine a city where roads suddenly vanish, cutting off neighborhoods from essential services.

Screen time and ADHD: why social media stands out from gaming and TV

Over four years in a large US cohort, greater social media use was associated with small but consistent increases in inattention symptoms in children, while video games and television were not. Genetic risk for ADHD did not modify this inattention association, and analyses supported a directional link from social media use to later attention difficulties.

AI turns routine pathology slides into powerful maps of the tumor immune landscape

A large study shows that routine H&E pathology slides contain rich spatial proteomic signals that can be decoded by AI to model the tumor immune microenvironment at population scale. By generating virtual multiplex immunofluorescence images, GigaTIME enables pan-cancer discovery of immune patterns linked to invasion stage, survival, and genomic alterations.

Filtered coffee shows a causal link to healthier HbA1c levels

Genetically predicted filtered coffee consumption is causally associated with lower HbA1c levels, while other coffee preparation methods show no such benefit. This effect appears to be partly mediated by increases in propionate producing gut bacteria, particularly Veillonella.

Researchers discover new biomarker of "complicated" mild- to severe-pediatric traumatic brain injury

Researchers at the University of Pittsburgh and UPMC Children's Hospital of Pittsburgh discovered a promising new biomarker of "complicated" mild- to severe-pediatric traumatic brain injury, or TBI.
