A daily dose of the antioxidant fisetin keeps mice—even those with genetic mutations linked to Alzheimer's—from experiencing memory and learning deficits as they age.

In adults, some brain regions retain a “childlike” ability to establish new connections, potentially contributing to our ability to learn new skills and form new memories as we age, according to new research from Washington University School of Medicine in St. Louis and the Allen Institute for Brain Science in Seattle.

To learn new motor skills, the brain must be plastic: able to rapidly change the strengths of connections between neurons, forming new patterns that accomplish a particular task. However, if the brain were too plastic, previously learned skills would be lost too easily.

In addition to being used as a recreational drug, marijuana has been used for centuries to treat a variety of conditions, from chronic pain to epilepsy. However, its medical value is greatly limited by debilitating side effects. A study published by Cell Press November 21st in the journal Cell has revealed the molecular pathways responsible for marijuana-induced learning and memory problems. The findings suggest that preventing these side effects could be as easy as taking an over-the-counter painkiller.

Growing up in poverty can have long-lasting, negative consequences for a child. But for poor children raised by parents who lack nurturing skills, the effects may be particularly worrisome, according to a new study at Washington University School of Medicine in St. Louis.

Protein synthesis in the extensions of nerve cells, called dendrites, underlies long-term memory formation in the brain, among other functions. “Thousands of messenger RNAs reside in dendrites, yet the dynamics of how multiple dendrite messenger RNAs translate into their final proteins remain elusive,” says James Eberwine, PhD, professor of Pharmacology, Perelman School of Medicine at the University of Pennsylvania, and co-director of the Penn Genome Frontiers Institute.
