Cancer Pathway Found to Weaken Brain and Eye Barriers

Researchers have uncovered a surprising connection between a cancer-related signaling pathway and the blood-brain and blood-retina barriers. The study shows that the tumor-suppressing protein p53 weakens the Norrin/Frizzled4 pathway, which is crucial for maintaining these protective barriers.

Genes and Brain Wiring Team Up in Alzheimer’s Spread

A new study reveals how genes influence where and how Alzheimer’s-related tau protein spreads in the brain. By combining imaging, gene data, and advanced modeling, researchers uncovered four gene pathways that either amplify or resist tau buildup, depending on brain connectivity.

Later-Born Neurons Mature Faster to Keep Networks in Balance

The brain depends on a delicate balance between excitatory and inhibitory neurons to function properly. A new study reveals that inhibitory neurons born later in development mature more quickly than earlier ones, allowing them to catch up and integrate evenly into neural networks.

Why Your Baby Cries: It’s Largely Written in Their Genes

A new twin study reveals that how much an infant cries is strongly influenced by genetics, leaving parents with limited control over this behavior. Researchers found that at two months, genetics accounted for around 50% of crying duration, rising to 70% by five months.

Stem Cell Grafts Show Promise in Repairing Myelin in MS

A new study reveals that neural stem cell grafts can generate new myelin in the central nervous system, offering hope for treating progressive multiple sclerosis (MS). Researchers showed that induced neural stem cells matured into myelin-producing oligodendrocytes and safely integrated into damaged regions in a mouse model.

Early Meals Boost Health, but Genetic Clock Shapes When We Eat

Our bodies process food differently depending on the time of day, and eating later has been linked to poorer metabolic health. A study of twins found that those who consumed most of their daily calories earlier had better insulin sensitivity and lower risk factors for diabetes and obesity.

Human Brains Keep Making Memory Neurons in Adulthood

A groundbreaking study shows that the human hippocampus continues producing new neurons well into late adulthood. Researchers identified neural progenitor cells—the precursors to neurons—in adults up to 78 years old, confirming ongoing neurogenesis in the memory center of the brain.

Gene Therapy Restores Hearing in Those with Deafness

A new study shows that gene therapy can significantly improve hearing in both children and adults with congenital deafness caused by mutations in the OTOF gene. The therapy uses a synthetic virus to deliver a healthy copy of the gene directly to the inner ear, with hearing improvements observed in all ten participants within one month.

Mimicking Exercise in the Brain Could Slow Cognitive Decline

While physical activity is known to slow cognitive decline in Alzheimer’s disease, many patients are unable to exercise due to frailty or advanced symptoms. A new study identifies a specific gene, ATPPIF1, that is reactivated through exercise and supports neuroplasticity in the brain.

One Gene Rewires Fear Circuits and Fuels Anxiety

Researchers have uncovered how losing the autism-linked gene PTEN in a specific set of inhibitory neurons reshapes brain circuits tied to fear and anxiety. Using advanced circuit-mapping techniques, they found that deleting PTEN in somatostatin-expressing neurons of the amygdala disrupted local inhibition by 50% while strengthening excitatory input from nearby brain regions.
