In the previous episode we saw how civilizations might not simply survive after all the stars in the Universe had died, but might indeed thrive far better during the Black Hole Era of the Universe. Today, we will go beyond even the Dark Era to examine the concepts or Iron Star Civilizations, Boltzmann Brains, Reversible Computing, and even reversing Entropy itself.

Sites in the brain where RNA is edited could help our understanding of neurodevelopment and disease

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

Mount Sinai researchers have cataloged thousands of sites in the brain where RNA is modified throughout the human lifespan in a process known as adenosine-to-inosine (A-to-I) editing, offering important new avenues for understanding the cellular and molecular mechanisms of brain development and how they factor into both health and disease.

In a study published in Cell Reports, the team described how the rate of RNA editing in the brain increases as individuals age, with implications for dissecting the pathology of altered A-to-I editing across a range of neurodevelopmental and aging disorders.

“Our work provides more nuanced and accurate insights into the contribution of RNA modifications by A-to-I editing during human brain development,” says senior author Michael Breen, Ph.D., Assistant Professor of Psychiatry, and Genetics and Genomic Sciences, at the Icahn School of Medicine at Mount Sinai, and a member of the Seaver Center for Autism Research and Treatment.

New research rethinks the blood-tumor barrier and identifies novel path to brain cancer treatment

Posted by in categories: biotech/medical, neuroscience

In a new study, scientists have uncovered the mechanics of the blood-tumor barrier, one of the most significant obstacles to improving treatment efficacy and preventing the return of cancerous cells. The research team, led by Dr. Xi Huang, a Senior Scientist in Developmental & Stem Cell Biology program at The Hospital for Sick Children (SickKids), lays the foundation for more effectively treating medulloblastoma, the most common malignant pediatric brain tumor.

“Despite decades of research on brain cancer, the mechanisms that govern the formation and function of the blood-tumor barrier have remained poorly understood,” says Huang, who is also a Principal Investigator at the Arthur and Sonia Labatt Brain Tumor Research Center and Canada Research Chair in Cancer Biophysics. “Our discoveries represent a breakthrough in the understanding of how the blood-tumor barrier forms and works.”

In a paper published today in Neuron, the research team identifies a way to reduce the impact of the blood-tumor barrier on medulloblastoma treatment.

New study links suffering from long-lasting severe depression to reduction in brain volume

Posted by in categories: biotech/medical, neuroscience

A study on a large sample of patients found chronic, long-lasting depression to be associated with reduced brain volume. The reduced volume was found in brain regions relevant for planning one’s behavior, focusing attention, thinking, learning and remembering and also in regions relevant for regulating emotions. The study was published in Neurobiology and Treatment of Depression.

Depression, also called major depressive disorder, is a mood disorder that causes a persistent feeling of sadness and loss of interest. It changes the way a person feels, thinks and behaves. For many people suffering from it, depressive episodes become a recurring event. More than half of patients with depression experience a relapse after 2 years and the probability of recurrent depressive episodes rises to 90% after 3–4 episodes. Studies have indicated that recurring depressive episodes might be linked to structural changes in the brain, but the existing results are not uniform.

Ms. Hannah Lemke and her colleagues analyzed the data of 681 patients from the Marburg-Muenster-Affective-Cohort Study (MACS) in order to better link properties of the course of depressive disorder with specific changes in the brain structure. Patient data were collected at two sites in Germany – Muenster and Marburg.

Seeking microscopic clues to beating deadly brain tumors

Posted by in categories: innovation, neuroscience

A critical new pathway to treating an aggressive brain tumor might be found in the complex diversity within the tumor tissue, according to a new paper by scientists from the Hackensack Meridian Center for Discovery and Innovation (CDI).

The CDI laboratory deeply analyzed tumor tissue using an advanced mass spectrometry with special focus on lipids, a class of molecules that includes fats, according to the new paper, in the journal Scientific Reports.

“Lipid ions presented here lay the foundation for future studies that are required to understand their interconnecting signaling pathways in relation to , tumor progression, and resistance to therapy,” according to the paper. “Understanding their functional relevance is essential for the identification of new therapeutics based on targets.”

New Clues Into a Serious Neurodegenerative Disease, Frontotemporal Dementia

Posted by in categories: biotech/medical, genetics, neuroscience

Summary: A genetic form of frontotemporal dementia is associated with abnormal lipid accumulation in the brain fueled by disrupted cell metabolism. The findings could pave the way for new targeted therapies for FTD.

Source: Harvard.

Dementia encompasses a range of neurodegenerative conditions that lead to memory loss and cognitive deficiencies and affect some 55 million people worldwide. Yet despite its prevalence, there are few effective treatments, in part because scientists still don’t understand how exactly dementia arises on a cellular and molecular level.
