3D Brain Map Reveals How Inflammation Reawakens Developmental Genes

Researchers have developed the most detailed molecular map yet of how the brain develops and reacts to inflammation, revealing that disease processes can “reawaken” genes from early life. Using a new spatial tri-omics technique, the team tracked how gene activity, epigenetic changes, and protein production interact in specific brain regions.

AI Maps the Brain’s Hidden Bridge, Revealing Genetic Links to Mental Health

For the first time, scientists have mapped the genetic architecture of the brain’s communication bridge—the corpus callosum—using AI and MRI data from over 50,000 people. The study uncovered dozens of genes that shape this vital structure’s size and thickness, many active during prenatal development when the brain’s wiring is established.

BrainSTEM Atlas Maps Every Cell of the Developing Human Brain

Scientists have built one of the most comprehensive single-cell maps of the developing human brain. The new BrainSTEM framework analyzed nearly 680,000 fetal brain cells to chart their growth and interactions, offering a detailed reference for studying neuron development.

Antioxidant Defense System in the Brain Discovered

A new study identifies biliverdin reductase A (BVRA) as a crucial enzyme defending neurons from oxidative stress, acting independently of its traditional role in bilirubin production. Using genetically modified mice, researchers found that BVRA binds directly to NRF2, a master regulator of antioxidant defense, ensuring the activation of protective genes that maintain cellular health.

How “Frazzled” Keeps the Brain Wired for Lightning-Fast Communication

Scientists have uncovered a key role for the protein “Frazzled” in building and maintaining the rapid neural connections that allow fruit flies to react in milliseconds. When Frazzled is missing, neurons lose vital gap junctions, slowing communication and weakening muscle responses.

$2 Saliva Test Could Help Detect Depression and Schizophrenia

Scientists have developed a portable biosensor that can detect levels of BDNF, a protein linked to mental health conditions such as depression, schizophrenia, and bipolar disorder. The flexible, low-cost device analyzes a drop of saliva in under three minutes, offering a fast, affordable, and noninvasive diagnostic tool.

Epigenetic Switch to Turn Memories On and Off Created

Researchers have shown for the first time that flipping an epigenetic “switch” in specific memory-holding neurons can directly alter memory strength. By targeting the gene Arc—which helps neurons adjust their connections—scientists used CRISPR-based tools to either boost or silence its activity in engram cells within the hippocampus.

Gene That Controls How Sensitive You Are to Alcohol Discovered

Researchers have discovered that a gene called CHRNA3 plays a key role in determining alcohol sensitivity, helping explain why some people tolerate alcohol better than others. When this gene was mutated, subjects were slower to avoid alcohol and consumed more of it, showing reduced sensitivity to its calming effects.

Hungry Brains Rewrite the Senses

When fruit flies lack essential amino acids, their brains rewire their sense of smell to help them find food rich in the nutrients they need. Researchers discovered that two genes—Or92a and Ir76a—boost the flies’ sensitivity to smells linked with fermented foods and bacteria that produce beneficial amino acids.

Alzheimer’s Disrupts Brain’s Internal Clock, Unraveling Gene Rhythms

Alzheimer’s disease not only damages memory but also distorts the brain’s internal clock, disrupting the daily rhythms of hundreds of genes tied to brain health. Researchers found that in mice with amyloid buildup, normal circadian gene activity in microglia and astrocytes—the brain’s immune and support cells—became erratic.

Gene Editing Reverses Age-Related Memory Loss

Researchers have identified molecular mechanisms behind age-related memory decline — and shown they can be reversed. Two studies revealed that correcting specific molecular processes in the hippocampus and amygdala, and reactivating a silenced memory-supporting gene called IGF2, improved memory in older rats.

New AI Tool Reveals Genetic Link Between Memory Cells and Alzheimer’s

A new computational tool developed by researchers has uncovered genetic evidence directly linking Alzheimer’s disease to the loss of memory-making neurons, helping to resolve a decades-long mystery in dementia research. The algorithm, called seismic, matches genetic data to individual cell types, outperforming previous methods and highlighting how specific brain cells—not just immune cells—are implicated in Alzheimer’s.
