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...

Immune Complex Shaves Stem Cells to Protect Against Cancer

extended data figure 18
Proposed model – The stromal inflammasome maintains tissue equilibrium by restraining Ras activity to impede premalignant-to-malignant transition.

A group of immune proteins called the inflammasome can help prevent blood stem cells from becoming malignant by removing certain receptors from their surfaces and blocking cancer gene activity, according to a preclinical study by Weill Cornell Medicine investigators.

The study, published in Nature Immunology, may lead to therapies that target the earliest stages of cancer. The findings bolster the idea that the inflammasome has a dual role: It promotes inflammation associated with poor outcomes in late cancer stages, but early on, it can help prevent cells from becoming cancerous in the first place.

“What was striking was that the in...
