The newly described oligodendrocyte progenitor cells (green) contact long-distance neuronal axons (magenta) on the wall of the brain ventricles. According to a study published June 20 in Science, scientists discovered two types of glial cells in the brains of adult mice - an astrocyte and an oligodendrocyte progenitor cell - after pushing neural stem cells to...
Scanning was completed both during Time 1 and Time 2 (approximately 1.5 years later) in each of the 5 age groups (6-year-olds, 10-year-olds, 14-year-olds, 16-year-olds, and 18+-year-olds).

On August 9, 2021, research from APC Microbiome Ireland (APC) at University College Cork (UCC), published in the leading international scientific journal Nature Aging, presents a new approach to invert aspects of brain deterioration and cognitive function related to aging through the microbes in the intestine. As our population ages, one of the leading global...

In a recent study, researchers observed that individuals with melancholia, a severe form of depression, displayed noticeably different reactions while watching emotionally charged films compared to those with less severe forms of depression. This finding could enable...

Daytime Sleepiness Linked to Early Signs of MCR These findings, from a new study by researchers at the Albert Einstein College of Medicine in...
Credit: Pixabay That refreshing sensation you experience when breathing in fresh air in nature might involve more than just the absence of pollution. While we typically associate nutrients with our diet, a closer examination of scientific studies reveals compelling evidence that humans can also absorb certain nutrients directly from the air. In a recent perspective article in...
With the help of an AI model trained on videos of surgery videos, a robot system has successfully carried out difficult surgical tasks as skillfully as a humanIntuitive Performing surgery takes years of training for humans, but a robot could learn the skill more easily with today’s AI technology. Researchers from Johns Hopkins University (JHU)...
Medical marijuana and cannabis products CBD oil, hemp leaves on a dark background. Flat lay, copy space Mockup For the first time, scientific evidence shows that a lesser-known component of the cannabis plant—cannabinol (CBN)—can provide longer and better-quality sleep. This breakthrough opens the door for the development of a cannabis-based sleep aid comparable to existing...
By analyzing your DNA and RNA with a computational pipeline and a curated database of pathogens, the mNGS system leads to far quicker diagnoses of rare diseasesGrumpyBeere / Pixabay (AI generated) Researchers at the University of California, San Francisco (UCSF) have developed an innovative genomic test capable of rapidly detecting nearly any pathogen in a...
Credit: Pixabay Author John Steinbeck once remarked, "It is a common experience that a problem difficult at night is resolved in the morning after the committee of sleep has worked on it." Many others have reported that they developed breakthroughs and innovations through dreams. Recent sleep science research suggests that modern findings support these claims. A 2024...
