Integrating mindfulness meditation and hard neuroscience data

Mindfulness meditation produces personal experiences that are not readily interpretable by scientists who want to study its psychiatric benefits in the brain. At the 12th Annual International Scientific Conference of the Center for Mindfulness near Boston in April, Brown University researchers described how they've been able to integrate mindfulness experience with hard neuroscience data to advance more rigorous study.

Anti-aging factor offers brain boost too

A variant of the gene KLOTHO is known for its anti-aging effects in people fortunate enough to carry one copy. Now researchers find that it also has benefits when it comes to brain function. The variant appears to lend beneficial cognitive effects by increasing overall levels of klotho in the bloodstream and brain.

Mitochondrial deficits in children with autism confirmed

Children with autism experience deficits in a type of immune cell that protects the body from infection. Called granulocytes, the cells exhibit one-third the capacity to fight infection and protect the body from invasion compared with the same cells in children who are developing normally.

Experiencing letters as colours: New insights into synaesthesia

Scientists studying the bizarre phenomenon of synaesthesia- best described as a "union of the senses" whereby two or more of the five senses that are normally experienced separately are involuntarily and automatically joined together- have made a new breakthrough in their attempts to understand the condition.
