Summary: Study exposes a new dynamic between the mammalian organism and the microbes that live inside their gut. Source: Cell Press. Even gut microbes have a routine. Like clockwork, they start their day in one part of the intestinal lining, move a few micrometers to the left, maybe the right, and then return to theirContinue reading “Gut Microbe Movements Regulate Host Circadian Rhythms”

THE LINK BETWEEN CIRCADIAN RHYTHMS AND AGING
MIT study finds that a gene associated with longevity also regulates the body’s circadian clock. Human sleeping and waking patterns are largely governed by an internal circadian clock that corresponds closely with the 24-hour cycle of light and darkness. This circadian clock also controls other body functions, such as metabolism and temperature regulation. Studies inContinue reading “THE LINK BETWEEN CIRCADIAN RHYTHMS AND AGING”
Brain Metabolism Predicts Fluid Intelligence in Young Adults
A healthy brain is critical to a person’s cognitive abilities, but measuring brain health can be a complicated endeavor. A new study by University of Illinois researchers reports that healthy brain metabolism corresponds with fluid intelligence – a measure of one’s ability to solve unusual or complex problems – in young adults. The results areContinue reading “Brain Metabolism Predicts Fluid Intelligence in Young Adults”
Researchers Discover Sandman’s Role in Sleep Control
Summary: A new study brings researchers one step closer to unlocking the mysteries of sleep. Source: University of Oxford. Oxford University researchers have discovered what causes a switch to flip in our brains and wake us up. The discovery, published in the journal Nature, brings us closer to understanding the mystery of sleep. Sleep isContinue reading “Researchers Discover Sandman’s Role in Sleep Control”
Brain may flush out toxins during sleep
NIH-funded study suggests sleep clears brain of molecules associated with neurodegeneration. A good night’s rest may literally clear the mind. Using mice, researchers showed for the first time that the space between brain cells may increase during sleep, allowing the brain to flush out toxins that build up during waking hours. These results suggest aContinue reading “Brain may flush out toxins during sleep”
Sleep Loss Tied to Gut Microbiota Changes in Humans
Summary: A new study reports sleep loss can lead to alterations in gut bacteria that have previousle been linked to diabetes and obesity in humans. Source: Uppsala University. Results from a new clinical study conducted at Uppsala University suggest that curtailing sleep alters the abundance of bacterial gut species that have previously been linked toContinue reading “Sleep Loss Tied to Gut Microbiota Changes in Humans”
Gut Bacteria Have Own Circadian Clock
Summary: Researchers report our gut bacteria is sensitive to melatonin and expresses its own circadian rhythm. Source: University of Kentucky. The circadian rhythm, or circadian clock, is an internal mechanism that drives the 24-hour cycles that tell our bodies when to sleep, wake and eat — and now, new research has found that bacteria livingContinue reading “Gut Bacteria Have Own Circadian Clock”
Scientists Find Surprising Answers to ‘Food Coma’ Conundrum
Summary: Researchers believe they may have found a reason for that all too well known holiday phenomenon, a ‘food coma’. Source: Scripps Research Institute. Anyone who has drifted into a fuzzy-headed stupor after a large holiday meal is familiar with the condition commonly known as a “food coma.” Now scientists from the Florida campus ofContinue reading “Scientists Find Surprising Answers to ‘Food Coma’ Conundrum”
Sleep scientists’ wake-up call for later school starts
By Jonathan WebbScience reporter, BBC News, Bradford As they prepare a major study to test the idea, UK scientists have said that starting school at 10:00 could have huge benefits for teenagers. Research suggests that society pays too little attention to our “body clock” – and adolescents in particular have a late-running biological rhythm. ThisContinue reading “Sleep scientists’ wake-up call for later school starts”
Why does our skin causing us to age?
Epigenetics studies genetic effects notencoded in the DNA sequence of an organism, hence the prefix epi- (Greek: επί– over, outside of, around).[1][2] Such effects on cellular and physiological phenotypic traits may result from external or environmental factors that switch genes on and off and affect how cells express genes.[3][4] These alterations may or may notContinue reading “Why does our skin causing us to age?”
Hypocretin, Insomia or Sleep Disturbances, Narcolepsy, Depression and Parkinson’s
Drowsy Driving Driving and feeling sleepy. Repetitive tasks make you sleepy because you already lack sleep. You have taken your calcium and magnesium and melatonin and the bedroom has cool environment. Still, you have worries and you keep tossing back and forth on your bed. You cannot get the more than 5 hrs sleep. YourContinue reading “Hypocretin, Insomia or Sleep Disturbances, Narcolepsy, Depression and Parkinson’s”
Sleep and Alzheimer
Eric Kandel: Short-term memory had been linked to functional changes in existing synapses, while long-term memory was associated with a change in the number of synaptic connections. Researchers at MIT have confirmed that sleep is essential for long-term storage of memories. Their study showed that mice unable to “replay” their awake experiences while asleep rememberContinue reading “Sleep and Alzheimer”
Can antidepressants cause neurodegenerative disease?
The following notes are compiled by Marcus William. Seek your doctor always. Neurological disorders, neurological damages, and progressive neurological dysfunction are all possible side effects of antidepressant use. And, in fact, acute neurological dysfunction is the standard and clinically desired outcome of antidepressant use, which begins with the first dose administered. Continued use may beContinue reading “Can antidepressants cause neurodegenerative disease?”
SW glitch in fMRI, brain scans faulty results
A 90 yr old Alzheimer’s patient in a care home has rigid body and when moved by caregivers from her bed or wheel chair, they feel that she is a dead weight. She cannot move most of her limbs. Every day her daughter would massage her head and she still has appetite and loves toContinue reading “SW glitch in fMRI, brain scans faulty results”
