NODE SMITH, ND Extended exposure to light during nighttime can have negative consequences for human health. But now, researchers from Japan have identified a new type of light with reduced consequences for physiological changes during sleep. In a study published in...

NODE SMITH, ND The psychedelic drug psilocybin, a naturally occurring compound found in some mushrooms, has been studied as a potential treatment for depression for years. But exactly how it works in the brain and how long beneficial results might last is still...

NODE SMITH, ND As smart watches are increasingly able to monitor the vital signs of health, including what's going on when we sleep, a problem has emerged: those wearable, wireless devices are often disconnected from our body overnight, being charged at the bedside....

NODE SMITH, ND Directing a meeting, dialing up an old acquaintance, dictating the perfect tuna salad sandwich across a drive-through window. For business and for pleasure, human beings are in constant communication. Our proclivity for socialization is lifelong,...

NODE SMITH, ND Working out just five minutes daily via a practice described as "strength training for your breathing muscles" lowers blood pressure and improves some measures of vascular health as well as, or even more than, aerobic exercise or medication, new CU...

NODE SMITH, ND Scientists have long searched in vain for a class of brain cells that could explain the visceral flash of recognition that we feel when we see a very familiar face, like that of our grandmothers. But the proposed "grandmother neuron" -- a single cell at...

NODE SMITH, ND A new University of Arizona Health Sciences study found women on hormone therapy were up to 58% less likely to develop neurodegenerative diseases including Alzheimer's disease, and reduction of risk varied by type and route of hormone therapy and...

NODE SMITH, ND A stimulating environment keeps the "hippocampus" -- which is the brain's memory control center -- young, so to speak. Causes of this are molecular mechanisms that affect gene regulation. These current findings from studies in mice provide clues as to...

NODE SMITH, ND Cells contain machinery that duplicates DNA into a new set that goes into a newly formed cell. That same class of machines, called polymerases, also build RNA messages, which are like notes copied from the central DNA repository of recipes, so they can...

NODE SMITH, ND A microfilter device that can easily separate and capture trace amounts of cancer cells in blood has been developed by a Kumamoto University research group. The palm-sized device is expected to contribute to the development of new cancer diagnostic...
