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.

Social Status and Genes Interact to Shape the Aging Brain

A global study of nearly one million individuals has identified hundreds of genetic regions linked to socioeconomic status, revealing a shared genetic signal across income, education, occupation, and deprivation. Researchers found that about 9% of the variation in socioeconomic status could be attributed to genetics, while the rest was driven by social and environmental factors.

Stress Genes Guide Cell Cleanup

New research has uncovered how the body clears dying cells during times of stress, shedding light on the unexpected role of classic stress-response genes. Using the model organism C. elegans, scientists tracked how these genes activate a pathway that helps remove cellular debris, a process essential for immune health and development.

Healthy Habits May Offset Brain Aging Linked to Shorter Telomeres

New research shows that healthy lifestyle choices can reduce the risk of stroke, dementia, and depression—even in people with biologically shortened telomeres. Telomeres are protective DNA caps that naturally shrink with age and environmental stress, increasing vulnerability to age-related brain diseases.

New Map Reveals First Steps of Protein Clumping in Alzheimer’s

Scientists have mapped how over 140,000 mutations affect the formation of amyloid beta fibrils, offering an unprecedented look at early events in Alzheimer’s disease. By combining DNA synthesis, genetically engineered yeast, and machine learning, they built a detailed energy landscape of the protein’s transition state—an elusive moment before plaque formation begins.
