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.

How modern diets are driving rapid evolution in gut bacteria

A novel iLDS statistic uncovers adaptive gene sweeps in gut bacteria, highlighting evolutionary responses to modern diets and enhancing microbiome studies.

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.

11 genetic loci that shape impulsive decision-making

Researchers identify distinct genetic loci involved in delay discounting and how these variants are involved in physical and psychiatric health outcomes.

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.

Why early- and late-onset depression are fundamentally different

Genetic differences in early- and late-onset depression highlight distinct risk profiles, informing targeted strategies for improved clinical outcomes.

Sensory effects of flavanols trigger physiological responses in the brain

Astringency is a dry, puckering, rough, or sandpapery sensation in the mouth caused by plant-derived polyphenols.

Bowhead whale’s secret to long life revealed: precision DNA repair may hold clues for human aging

Researchers discovered that bowhead whales achieve extraordinary longevity and cancer resistance through highly efficient and precise DNA repair mechanisms. A whale-specific protein, CIRBP, enhances genome stability even in human cells, revealing a potential pathway to strengthen DNA repair and slow aging.

Unlocking memory: The role of epigenetics in memory expression

Our experiences leave traces in the brain, stored in small groups of cells called "engrams". Engrams are thought to hold the information of a memory and are reactivated when we remember, which makes them very interesting to research on memory and age- or trauma-related memory loss.

Fruit flies illuminate the role of Alzheimer's disease risk genes

Scientists have identified hundreds of genes that may increase the risk of developing Alzheimer's disease but the roles these genes play in the brain are poorly understood.

MRI age clocks reveal how each organ ages differently and predict who develops disease or lives longer

Researchers developed seven MRI-based biological age clocks across major organs using UK Biobank imaging, linking each to proteins, metabolites, genetics, disease risks, mortality, and cognitive decline. These organ-specific age gaps reveal how uneven aging shapes vulnerability to conditions such as diabetes, hypertension, and dementia, opening new paths for precision prevention and clinical trial stratification

How age influences the perception of ambiguous facial expressions

Do you find it easy to perceive people you meet as happy and positive? Or are you vigilant and look for signs of dissatisfaction and anger in their facial expressions?

Genetic risk scores fail to predict survival after diagnosis

Research indicates that disease susceptibility genetics poorly predict survival, while longevity PGSs offer stronger associations with post-diagnosis mortality.

Scientists uncover 53 genetic clues that shape math ability beyond IQ

Researchers uncovered 53 genetic loci linked to quantitative ability, distinguishing it from general intelligence and non-cognitive skills. The study highlights brain pathways in axon guidance, synaptic signaling, and mRNA splicing as biological underpinnings of math-related ability.

Genetic study shows dual GIPR/GLP1R action curbs binge alcohol use

Researchers used drug-target Mendelian randomization to test whether genetically proxied activation of GLP1R and GIPR influences alcohol-related behaviors. They found that GIPR, especially when combined with GLP1R, was linked to lower binge and heavy drinking, healthier food preferences, improved liver markers, and reduced coronary artery disease risk.

Genes play an active role in shaping the gut bacteria, study finds

New research from the University of Sydney's Charles Perkins Centre has found that genes play an active role in shaping the bacteria found in our gut, questioning the idea that gut health is influenced only by diet.
