As mindfulness practices rise in popularity and evidence of their worth continues to accumulate, those who work with aging populations are looking to use the techniques to boost cognitive, emotional and physiological health. But studies so far have shown mixed results in the elderly.

Keeping blood sugar levels within a safe range is key to managing both type 1 and type 2 diabetes. In a new finding that could lead to fewer complications for diabetes patients, Yale School of Medicine researchers have found that changes in the size of mitochondria in a small subset of brain cells play a crucial role in safely maintaining blood sugar levels.

Striking electron microscope pictures from inside the brains of mice suggest what happens in our own brain every day: Our synapses – the junctions between nerve cells - grow strong and large during the stimulation of daytime, then shrink by nearly 20 percent while we sleep, creating room for more growth and learning the next day.

Results of a multicenter study of 129 women with advanced breast cancer show that a blood test that spots cancer-linked DNA correctly predicted that most of those patients with higher levels of the tumor markers died significantly earlier than those with lower levels.

In a second human case, a Yale-led research team has found that a melanoma cell and a white blood cell can fuse to form a hybrid with the ability to metastasize. The finding provides further insight into how melanoma and other cancers spread from solid tumors with implications for future treatment.

Body shaming is a pervasive form of prejudice, found in cyber bullying, critiques of celebrities’ appearances, at work and school, and in public places for everyday Americans. People who are battling obesity face being stereotyped as lazy, incompetent, unattractive, lacking willpower, and to blame for their excess weight. The pain of these messages may take a toll on health and increase risk of cardiovascular and metabolic disease.

Researchers at Columbia University Medical Center have linked excess tau protein in the brain to the spatial disorientation that leads to wandering in many Alzheimer's disease patients. The findings, in mice, could lead to early diagnostic tests for Alzheimer's and point to treatments for this common and troubling symptom.

A synthesized steroid mirroring one naturally made by the dogfish shark prevents the buildup of a lethal protein implicated in some neurodegenerative diseases, reports an international research team studying an animal model of Parkinson’s disease. The clustering of this protein, alpha-synuclein (α-synuclein), is the hallmark of Parkinson’s and dementia with Lewy bodies, suggesting a new potential compound for therapeutic research.

A clump of just a few thousand brain cells, no bigger than a mustard seed, controls the daily ebb and flow of most bodily processes in mammals -- sleep/wake cycles, most notably. Now, Johns Hopkins scientists report direct evidence in mice for how those cell clusters control sleep and relay light cues about night and day throughout the body.
