'Pretty' parrots are more likely to be snatched up for Indonesia's illegal wildlife trade, a new study reveals. The findings not only expose the key drivers behind the country's illegal trade in these birds, but offer lessons for the potential emergence and spread of infectious diseases that jump from animals to humans.

Young children who practice visual working memory and reasoning tasks improve their math skills more than children who focus on spatial rotation exercises, according to a large study. The findings support the notion that training spatial cognition can enhance academic performance and that when it comes to math, the type of training matters.

More evidence has been uncovered that Alzheimer’s disease may actually be a third form of diabetes, according to researchers from Northwestern University.

Insulin and insulin receptors in your brain are crucial for learning and memory, and it’s known that these components are lower in people with Alzheimer’s disease. In your brain, insulin binds to an insulin receptor at a synapse, which triggers a mechanism that allows nerve cells to survive and memories to form.

The Northwestern University researchers have found that a toxic protein in the brain of Alzheimer’s patients -- called ADDL for “amyloid ß-derived diffusible ligand” -- removes insulin receptors from nerve cells, and renders those neurons insulin resistant.

The findings suggest that ADDLs accumulate at the beginning of Alzheimer’s disease and thereby block memory function.

The process is currently thought to be reversible.

The researchers speculated that drugs used to treat type 2 diabetes, which also causes insulin resistance, may “supercede currently available Alzheimer’s drugs.”
