Diabetes drug makes brain cells grow

A diabetes drug called metformin has been found to promote the growth of new brain cells and enhance spatial memory formation. The study's lead author suggests that the widely used medication may also offer cognitive benefits for people with Alzheimer's disease, independent of its effects on blood sugar control.

Stem cell transplantation into mouse cochlea may impact future hearing loss therapies

Researchers in Japan have concluded that adult-derived induced pluripotent stem (iPS) cells and mouse embryonic stem (ES) cells demonstrate similar survival and neural differentiation capabilities when transplanted into mouse cochleae. However, iPS cell transplantation is associated with a risk of tumor growth, highlighting the importa...

Highways of the brain: High-cost and high-capacity

A new study proposes a communication routing strategy in the brain that mimics the American highway system, with select hubs forming the influential network known as the 'rich club'. This network provides quick and effective communication between billions of brain cells, with long-distance neural pathways favoring rich club connections.

Locating ground zero

Microglia, the brain's emergency workers, use a long-lasting glutamate-driven calcium wave to detect injuries, allowing them to trace the signal backwards until they reach the site of damage. This discovery could lead to new treatments for conditions such as Alzheimer's and Parkinson's diseases.

Stem cell research paves way for progress on dealing with Fragile X retardation

Researchers at Hebrew University of Jerusalem have successfully generated neuronal cells from stem cells of Fragile X patients, paving the way for restoration of normal gene expression. The study identified a chemical compound, 5-azaC, that can clear methyl groups and reactivate FMR1 gene expression in both stem and neuronal brain cells.

Discovery of a new family of key mitochondrial proteins for the function and viability of the brain

A team of scientists has discovered a new family of six genes that regulate mitochondrial transport in neurons, which is crucial for brain activity and viability. The proteins are highly expressed in the nervous system and may be involved in neurological conditions such as Parkinson's disease and Charcot-Marie-Tooth disease.

How does the immune system fight off threats to the brain? New research yields fresh insight

Researchers have discovered that immune cells in the brain use a two-tier approach to combat infections, sending signals to neighboring cells while focusing their attack on infected cells. This finding may help researchers develop new treatments for brain tumors and autoimmune diseases.

Locked down, RNA editing yields odd fly behavior

Brown University researchers found that RNA editing enzyme activity varies with temperature, affecting fly behavior in mating and daily routines. High or low self-editing levels can create different personalities, such as wallflowers or pick-up artists, highlighting the significance of this process in animal behavior.
