Smarter Minds Predict Better: IQ Linked to Sharper Life Forecasting

New research reveals that individuals with higher IQs are significantly better at predicting future outcomes, leading to smarter decision-making. Using data from the English Longitudinal Study of Ageing, researchers assessed how accurately people over 50 could estimate their own life expectancy. High-IQ individuals were found to make more precise forecasts—errors were less frequent and less extreme compared to their lower-IQ counterparts.

Shared Genetic Roots of Autism and Heart Disease Found

New research reveals that autism and congenital heart disease may share a common biological basis—tiny cellular structures called cilia. Scientists found that mutations in genes affecting cilia formation disrupt both brain and heart development, helping explain why the two conditions often co-occur.

Newborns and Alzheimer’s Patients Share a Brain Protein Spike

A new study has revealed that newborn babies and Alzheimer’s patients both have elevated levels of the same protein, p-tau217, in their blood. While this protein is a key marker of brain degeneration in Alzheimer’s, in newborns it appears to support healthy brain growth and development.

Aging Spreads Through the Bloodstream

New research reveals that aging isn't just a local cellular process—it can spread throughout the body via the bloodstream. A redox-sensitive protein called ReHMGB1, secreted by senescent cells, was found to trigger aging features in distant tissues, impairing regeneration and muscle function.

Caffeine Gives Cells an Energy Boost Against Aging

New research shows that caffeine may help slow ageing at the cellular level by activating AMPK, a key energy-sensing pathway. Using fission yeast as a model for human cells, scientists found that caffeine boosts AMPK activity, which helps cells manage stress, repair DNA, and regulate growth.

Could This Molecule Prevent Vision Loss in AMD?

A new study reveals that increasing levels of apolipoprotein M (ApoM) may slow or prevent the progression of age-related macular degeneration (AMD), a major cause of blindness in older adults. Researchers found that low ApoM impairs cholesterol metabolism in the retina, contributing to inflammation and vision loss—especially in advanced forms like geographic atrophy.

Rare Mutation Shields Brain from Alzheimer’s by Silencing Inflammation

A rare genetic mutation known as APOE3-R136S, or the “Christchurch mutation,” appears to protect against Alzheimer’s disease by suppressing inflammatory signaling in the brain’s immune cells. Researchers found that this mutation dampens the cGAS-STING pathway, a key innate immune mechanism that is abnormally activated in Alzheimer’s and other neurodegenerative disorders.

New Autism Data Reveals Insights Into Profound Cases

Researchers have released genetic and behavioral data from over 1,500 children and adolescents with autism who were hospitalized in psychiatric units across the U.S. This group, often representing those with profound autism—marked by minimal language and high support needs—has been largely missing from previous datasets.

Glial Cell Transplants Slow Huntington’s Symptoms and Extend Life

A new study reveals that transplanting healthy human glial progenitor cells into adult mice with Huntington’s disease can delay motor and cognitive decline and extend lifespan. These support cells restored key neuronal functions, reversed synaptic damage, and reactivated gene expression even after symptoms began.

Different Autism Genes, Same Brain Signature

New research shows that different genetic forms of autism may produce a shared brain activity pattern, revealing a potential common neural signature despite distinct genetic origins. Using brain-wide recordings in preclinical models, scientists observed that autism-linked mutations affected how expectations are updated during decision-making.

Exercise Rewires Alzheimer’s-Affected Brain Cells

Using cutting-edge RNA sequencing, researchers mapped how exercise affects specific brain cell types in a model of Alzheimer’s disease. They found that physical activity alters gene activity in microglia and a newly identified type of astrocyte linked to blood vessels, which may protect memory.
