Stronger slow-wave sleep helps older adults regulate anxiety overnight

Researchers at Center for BrainHealth at The University of Texas at Dallas have identified a specific feature of sleep that helps older adults regulate anxiety overnight - and shown that, as it deteriorates with age, emotional wellbeing deteriorates along with it.

Genetic variants may help explain who loses more weight and who gets side effects on GLP-1 drugs

A large 23andMe-based GWAS found that common variants in GLP1R and GIPR help explain why some people lose more weight or experience more nausea and vomiting on GLP-1 drugs. The findings suggest genetics may eventually help predict who responds best to semaglutide or tirzepatide and who is more likely to develop side effects.

Interpretable machine learning model advances analysis of complex genetic traits

A new study published in Genome Research presents an interpretable artificial intelligence framework that improves both the accuracy and transparency of genomic prediction, a key challenge in fields such as precision medicine, crop science, and animal breeding.

Alcohol consumption in early adulthood linked to middle age cognitive decline

It's well known that alcohol consumption is an age-old method for coping with stress. But surprising? research led by the University of Massachusetts Amherst found that, when such self-medication begins in early adulthood, negative cognitive effects start to show up in middle-age-even after long periods of total abstinence.

New review reveals complex polygenic architecture underlying common epilepsies

An insightful mini-review published in Genomic Psychiatry synthesizes the rapidly expanding landscape of molecular genetic research on common epilepsies, assembling evidence from genome-wide association studies, whole-exome sequencing projects, and advanced statistical modeling to illuminate the polygenic architecture that underpins these heterogeneous neurological disorders.

Genome sequencing data reveals new insights into Epstein-Barr virus immunity

The Epstein-Barr virus (EBV) can cause certain types of cancer or autoimmune diseases, but how the body controls this common viral infection is largely unknown.

Shared genetic architecture links schizophrenia with hemispheric white matter microstructure

Schizophrenia is a highly heterogeneous psychiatric disorder affecting ~1% of the global population, typically emerging in adolescence or early adulthood and characterized by hallucinations, delusions, disorganized thinking, and cognitive impairments; while its etiology remains elusive, genetic factors are widely recognized as fundamental, and GWAS have identified over 200 genome-wide significant loci.

The neuroscience of motivation-driven memory retention

Researchers from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), and Duke University have proposed a neuroscience framework explaining how different types of motivation fundamentally reshape what and how the brain remembers.

Alternative splicing of DOC2A gene shown to drive schizophrenia risk

In an important new study, Chinese researchers have discovered the previously unrecognized role of alternative splicing of the DOC2A gene in schizophrenia.

FDA-cleared ADHD device not effective in reducing symptoms

A large multicenter clinical trial led by King's College London with 150 children and adolescents has shown that a device cleared by the US FDA to treat ADHD is not effective in reducing symptoms.

CRISPR-Cas3: A safer gene-editing tool shows promise for transthyretin amyloidosis treatment

Genetic disorders occur due to alterations in the primary genetic material, deoxyribonucleic acid (DNA), of an organism. Transthyretin amyloidosis (ATTR) is a progressive disorder involving amyloid deposits of misfolded transthyretin (TTR) proteins.

CRISPR Cas12a3: A precise tool to halt viral protein production

Across all domains of life, immune defenses foil invading viruses by making it impossible for the viruses to replicate. Most known CRISPR systems target invading pathogens' DNA and chop it up to disable and modify genes, heading off infections at the (cellular) pass.

Jumping genes reshape cancer genomes through 3D chromatin interactions

Scientists at St. Jude Children's Research Hospital have revealed previously unappreciated roles for the retrotransposon LINE-1 in shaping the cancer genome structure and regulation.

Homer1 gene plays a critical role in shaping attention

Attention disorders such as ADHD involve a breakdown in our ability to separate signal from noise. The brain is constantly bombarded with information, and focus depends on its ability to filter out distractions and detect what matters.

Expanded donor matching makes stem cell transplants accessible

For years, the search for a stem cell donor has felt like a quest for a rare key-one that fits a lock with eight intricate tumblers, each representing a genetic marker.

Genetic signals reveal why erectile dysfunction develops and who is most at risk

This multi-ancestry genomic study identifies key genetic loci underlying erectile dysfunction and shows that ED risk is shaped by both cardiometabolic and substance use–related genetic pathways. Using EHR-linked data, the researchers uncover SIM1-related mechanisms, modest PRS performance, and bidirectional genetic links with obesity, diabetes, and addiction traits.
