Recessive Genes May Quietly Shape Health, Learning, and Fertility

Carriers of recessive gene mutations, long thought to be unaffected, may actually face subtle disadvantages, including more medical issues, shorter educational attainment, and reduced reproductive success. A study of over 300,000 individuals reveals that people who carry recessive genes for intellectual disability are especially impacted, despite having only one mutated gene copy.

Tiny Gene Fragment Key to Memory Revealed

Researchers have discovered that a nine–amino acid microexon spliced into the DAAM1 gene is critical for memory formation, functioning exclusively in neurons. Deleting this microexon in mice resulted in fewer synaptic spines—essential structures for learning and memory—and caused a 40% decline in memory performance.

Protein Differences Between Sexes Aren’t All Genetic

An international study of 6,000 proteins across 56,000 people found that while protein levels differ significantly between males and females, most of these differences are not caused by genetics. Only about 100 proteins showed sex-specific genetic regulation, suggesting that environmental, hormonal, and lifestyle factors play a major role in shaping health outcomes.

Century-Old Mystery May Hold the Key to Diabetic Nerve Pain

A little-known cellular structure called the Nageotte nodule—first described over 100 years ago—has been identified as a key feature of diabetic neuropathy in new research. These nodules, made of decayed sensory neurons and support cells, were found in abundance in the sensory ganglia of diabetic organ donors.

Mapping the Cellular Secrets of Glioblastoma

Two landmark studies have mapped the complex cellular ecosystems of glioblastoma, the deadliest form of brain cancer, offering unprecedented insights into how its diverse cells evolve and resist treatment. Using single-cell RNA sequencing on over 430,000 cells from 59 patients, researchers identified three new glioblastoma cell states and classified tumors into three overarching cellular ecosystems.

Exercise Boosts Stem Cell Therapy for Parkinson’s

Exercise enhances the effectiveness of stem cell-derived neuron transplants in a Parkinson’s disease (PD) rat model. Transplanted neurons alone improved basic motor functions, but when combined with voluntary exercise, the rats displayed significantly better agility and paw control.

Bigger Brains and Strong Immunity Linked to Longer Lifespans

New research reveals that mammals with larger brains and more robust immune systems tend to live longer lives. By studying 46 species, scientists found a clear link between maximum lifespan and the expansion of immune-related gene families.

Parental Genes Indirectly Influence Child Development

A new report reveals that parents' genes influence their children's educational and mental health outcomes, even when not directly inherited. This phenomenon, called "genetic nurture," shows that parents' genetic tendencies—such as valuing education or possessing strong non-cognitive skills—shape the home environment and positively impact child development.

Boosting Klotho Protein Slows Aging and Enhances Health

Increasing levels of the Klotho protein can slow aging and improve health across multiple systems. Scientists showed that mice treated to produce more secreted Klotho (s-KL) had better muscle strength, bone density, cognitive function, and even lived 15–20% longer.

Genes Strongly Influence When Babies Take Their First Steps

New research reveals that genetics play a major role in determining when babies begin walking, accounting for about 25% of the variation in this milestone. In a study analyzing data from over 70,000 infants, scientists identified 11 genetic markers linked to the timing of first steps.

Genetics, Not Parenting, Shapes Personality

New research challenges many widely held beliefs in psychology, revealing that genetics may play a greater role in shaping personality than parenting. The findings also dispute common assumptions about gender-based personality differences, the power of subliminal messaging, and the effectiveness of brain training.

Can Genetics Predict Autism Intellectual Disabilities?

A new predictive model combining genetics with developmental milestones may help forecast which autistic children are at risk of developing intellectual disabilities. In a large study of over 5,600 children, researchers were able to correctly predict 10% of such cases and differentiate between low and high-risk groups twice as well as current methods.
