Study: Biological underpinnings of autism and ADHD may transcend traditional diagnostic boundaries

A new study published in Molecular Psychiatry reveals that the biological underpinnings of autism and ADHD may transcend traditional diagnostic boundaries.

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.

New feedback mechanism in the brain could open avenues for treating people with sleep disorders

As every bodybuilder knows, a deep, restful sleep boosts levels of growth hormone to build strong muscle and bone and burn fat.

Smell loss emerges as the early behavioural sign of Alzheimer’s

Research reveals immune cells target brainstem nerves, linking smell loss to early Alzheimer's, offering potential for earlier diagnosis and intervention.

Breastfeeding at six months boosts children’s IQ and academic skills into adolescence

Breastfeeding at six months was linked to higher IQ, better reading and math skills, and improved conversational abilities in children, according to the ALSPAC study. The findings, based on 42 significant outcomes, highlight long-term cognitive advantages but stop short of proving causality.

Alzheimer’s gene risks differ by ancestry, major study reveals 133 new variants

Researchers used whole-genome sequencing from diverse populations to identify 156 variants, including 133 novel ones, linked to Alzheimer’s disease and related dementias. The study highlights ancestry-specific genetic risk and protective factors, challenging one-size-fits-all approaches to dementia genetics.

Study shows probiotics help preterm babies fight antibiotic-resistant bacteria

Researchers found that probiotics help reduce antibiotic-resistant bacteria in the guts of very-low-birth-weight preterm infants, but cannot fully prevent resistance genes from spreading. Antibiotic use still promotes gene swapping, highlighting the limits of probiotics alone in neonatal care.

Researchers uncover dozens of traits driven by maternal versus paternal genes

Researchers developed a high-accuracy method to infer whether genetic variants come from the mother or father without needing parental genomes, analysing 286,666 UK Biobank participants. They uncovered over 30 parent-of-origin effects on traits from growth and metabolism to diabetes, many showing opposite effects depending on parental source.

HOXB13 emerges as a context-dependent regulator in cancer biology

HOXB13, a B-class homeobox transcription factor, sits at the hub of developmental gene networks yet has emerged as a double-edged sword in human cancer.

Scientists reveal how rare gene mutations drive schizophrenia risk

Researchers analyzed the largest exome-sequencing dataset to date and identified new rare coding variants and genes linked to schizophrenia risk. The study highlights converging genetic pathways, implicating chromatin organization and GABAergic signaling in schizophrenia neurobiology.

Researchers trace metabolic superpowers of hibernators to shared DNA

Animals that hibernate are incredibly resilient. They can spend months without food or water, muscles refusing to atrophy, body temperature dropping to near freezing as their metabolism and brain activity slow to a crawl.
