Only 1% less sleep increases senior brain risk of dementia.

Only 1% less sleep increases senior brain risk of dementia.

The thing that makes this study interesting is that it can uncover Alzheimer's mechanisms. There is a possibility that dementia is a metabolic disease. When a person gets less sleep neurons cannot recover themselves.

Traffic noise and waking up too long act like some kind of nerve gas. Neurons can't remove their adjustment during the night. And that thing makes it possible for neurons to get tired. That means neurons have no time to load new fresh neurotransmitters during sleep. And that thing causes overactivity in neurons.

The neuron doesn't have time to remove its metabolic productions. This can be one reason for the deadly plague that is visible in Alzheimer patient's brains. That plaque isolates neurons from each other. There could be many things that can cause Alzheimer's. And one of them is that metabolic waste starts to fill the cell.

There is a possibility that those metabolic produces deny the neuron's axons' actions. This is one thing that explains why the cleaner cells don't remove plaque between neurons. And sooner or later the plaque isolates the neuron. Then the neuron cannot get nutrients and it dies. That starts death in other neurons.

This can be one version of dementia's last period. The plaque plays a vital role in Alzheimer's disease. Plaque itself may cover neurons or their support cells closing the ion pumps and causing death.

The plaque itself causes changes in the needed quantity of neurotransmitters. The neuron must send more neurotransmitters through plaque. And that causes the mental overreaction that we see as anger. This is one version of the Alzheimer's.

The hydrogen-burning supernovas are interesting models.

"Researchers discovered a significant magnesium anomaly in a meteorite’s dust particle, challenging current astrophysical models and suggesting new insights into hydrogen-burning supernovas. (Artist’s concept.)Credit: SciTechDaily.com" (ScitechDaily, Rare Dust Particle From Ancient Extraterrestrial Meteorite Challenges Astrophysical Models) If the star is too heavy when its fusion reaction starts, it can detonate just at that moment, when its fusion starts. If the collapsing nebula is heavy enough, it can form a black hole straight from the nebula. But if the nebula's gravity is too heavy to form the blue giant or too small it can collapse straight into a black hole . If the forming star is a little bit larger than the blue supergiants. It can explode immediately when the fusion starts. The theory of hydrogen-burning supernovas consists model of the giant stars that explode immediately after their fusion starts. When the...

The ancient galaxy mirrors the Milky Way.

"This image shows the galaxy REBELS-25 as seen by the Atacama Large Millimeter/submillimeter Array (ALMA), overlaid on an infrared image of other stars and galaxies. The infrared image was taken by ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). In a recent study, researchers found evidence that REBELS-25 is a strongly rotating disc galaxy existing only 700 million years after the Big Bang. This makes it the most distant and earliest known Milky Way-like galaxy found to date. Credit: ALMA (ESO/NAOJ/NRAO)/L. Rowland et al./ESO/J. Dunlop et al. Ack.: CASU, CALET" (ScitechDaily, Astronomers Baffled by Ancient Galaxy That Mirrors Modern Milky Way) Researchers found the youngest Milky Way-type galaxy. The distance to the galaxy is enormous. And the light that comes from that galaxy named REBELS-25 comes from the Universe that is only 700 million years old. The distance to that galaxy is enormous about 236 billion light years. And that means it's a very dista...

Transcendence, or the ability to transcendent thinking may grow in teen's brains.

"New research has discovered that transcendent thinking, which involves analyzing the broader implications of situations, can foster brain growth in adolescents. This form of thinking enhances brain network coordination, impacting developmental milestones and future life satisfaction. The study emphasizes the need for education that encourages deep, reflective thought, underscoring the critical role of adolescents in their own brain development". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) "Scientists at USC Rossier School of Education’s Center for Affective Neuroscience, Development, Learning and Education (CANDLE) have discovered that adolescents who grapple with the bigger meaning of social situations experience greater brain growth, which predicts stronger identity development and life satisfaction years later". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) The transcendenc...
