Meditation, Art and Nature: Neuroimaging reveals distinct patterns of brain activation

Past research suggests that meditation and exposure to art or nature can positively impact people’s well-being and brain health, in some cases even reducing stress and supporting the processing of emotions. Yet most past studies focused on each of these experiences individually, rather than comparing their effects on brain activity.

Researchers at University of California Los Angeles set out to examine the brain activation patterns associated with a visualization-based transcendental meditation of connecting to the cosmic soul and compare them to those from people watching evocative digital art or nature videos.

Their findings, published in Frontiers in Human Neuroscience, suggest that these different types of transcending experiences prompt different brain activation patterns.

Gardenia Plants may hold Chemical Key to Regenerating Diseased Human Nerves

Gardenias are known for their rich, earthy fragrance, waxy petals and brilliant white color that contrasts with the deep emerald green of their leaves. The plant has long been prized by herbalists, seekers of food and fabric dyes, and even pharmaceutical companies.

Now, a collaborative team of scientists at several research centers in the United States has found that a compound known as genipin, derived from the gardenia plant called Cape jasmine, can prompt nerve regeneration. Neurons damaged and stunted by disease find new life in the lab when exposed to the plant-derived compound.

The chemical comes from the fruit of this extraordinarily versatile plant...

People with pockets of fat hidden inside their muscles are at a higher risk of dying or being hospitalized from a heartattack or heart failure, regardless of their body mass index, according to research published in the European Heart Journal.

This ‘intermuscular’ fat is highly prized in beef steaks for cooking. However, little is known about this type of body fat in humans, and its impact on health...

Xenon Gas could Protect Against Alzheimer’s Disease: Mouse study

Three researchers in a research lab at Brigham and Women’s Hospital pose next to a machine used to deliver Xenon gas
From left: Anesthesiologist Christopher Connor will work with principal investigator Howard Weiner to deliver Xenon gas as part of a BWH clinical trial that builds on Alzheimer’s disease prevention research led by Oleg Butovsky.

Xenon gas inhalation reduced neurodegeneration and boosted protection in preclinical models of Alzheimer’s disease. Most treatments being pursued today to protect against Alzheimer’s disease focus on amyloid plaques and tau tangles that accumulate in the brain, but new research from Mass General Brigham and Washington University School of Medicine in St. Louis points to a novel — and noble — approach: using Xenon gas...
