A stroke can destroy brain cells within minutes, often... leaving people with long‑term problems in movement, memory, or speech. But scientists may have found a way to help the brain heal itself. In studies of mice, researchers injected stem cells into areas of the brain damaged by stroke. These stem cells began turning into early‑stage brain cells, and many later developed into active neurons that connected with surrounding tissue. The treatment did more than just grow cells.show more

The cycle of life, every instant, in your mitochondria.... The major electron carrier in mitochondria is NAD+. When it collects an electron from the food you eat, NAD+ is converted into NADH. NADH then feeds the electron to the electron transport chain so the electron can flow to oxygen - the ultimate electron acceptor. How easily electrons make their way to oxygen determines energy resistance (éR) following the energy resistance principle (ERP) Mitochondrial matrix and cell cytoplasm are two different "sealed" compartments, but there is a special system that connects the NAD+/NADH pools between mito and cytoplasm: the Malate-Aspartate shuttle The Malate-Aspartate shuttle shown below is how NADH from the cytoplasm (made by glycolysis) is carried into mitochondria. The electron transport chain can then regenerate NAD+ by respiring the flowing electron. Everywhere in biology: energy transfer. Sometimes without molecular carriers. Here with a number of enzymatic intermediates, creating an integrated electrical circuit. The circuit is in service of the flowing electron looking for a place to rest. Getting back onto oxygen to become H2O (water) again, as it was initially before getting ripped off by light energy and stuck onto a carbon backbone in a green leaf.

⚠️ I can’t overstate how CATOSTROPHIC this Ice Storm... could be if the models are even half right. 🧊The Model AVERAGES are showing around 1 inch of Ice Accumulation from Texas, through Louisiana, Arkansas, Mississippi, Georgia, Alabama, and into the Carolinas. Some Models (like the generally reliable Euro Model) even have a crippling 1-2" of Ice accumulating there. 🧊 To put Ice amounts into perspective: 🧊0.25” – Highly disruptive. Iced roads, scattered power outages, tree and line damage. 🧊0.5” – CRIPPLING. Severe tree damage and widespread, long-lasting power outages. 🧊1” or more – Catastrophic. Infrastructure failure, impassable roads, and weeks-long power outages. ⚠️ This is why this setup is so concerning. A prolonged, multi-day freezing rain event would lead to disastrous ice accumulations. 🙏 Let’s hope the models are overdoing this, because if they aren’t, the South could be in serious trouble. Don't panic yet. There is still time for trends to change. I'll be live at 7:00pm ET to talk through this. Hang in there. I'll help get you through this my brotherenshow more

China: During Covid, a green QR code was required... to access all aspects of daily life—public transport, stores, going to work, etc. But the only way to acquire a green QR code was to produce a negative Covid test every 48 hours. This is what life will soon be like in the West if we allow our governments to succeed in rolling out digital ID. Before long, every aspect of daily life will require a valid digital ID, and the conditions of validity can be set to anything they want—forcing you to comply with whatever you're told, or get locked out of society. In other words, it would give authorities complete and total control over your entire life.show more

🚨 Scientists discover wisdom teeth contain stem cells capable... of repairing the heart, brain, and bones. Wisdom teeth contain dental pulp, a soft connective tissue threaded with blood vessels and nerves. Inside that pulp lives a dense population of mesenchymal stem cells, a class of undifferentiated cells that researchers classify as among the most therapeutically valuable biological material a human body produces. These are not ordinary cells maintaining routine tissue. They are blueprint cells, capable of receiving chemical signals from damaged environments and reshaping themselves into whatever the body needs most, neurons, cardiomyocytes, osteoblasts, even hepatic cells under the right conditions. The brain operates under a brutal rule: most of its neurons do not regenerate after damage. A stroke, a traumatic injury, a neurodegenerative disease removes cells the brain cannot replace through normal biological processes. Researchers have spent decades attempting to solve this through synthetic means, engineered cell therapies, growth factor injections, gene editing approaches that cost extraordinary resources and produce inconsistent results. What dental pulp stem cells demonstrated in laboratory conditions is that they can migrate toward neural damage sites, integrate with existing tissue architecture, and begin producing neurons and glial support cells. The mechanism involves neurotrophic factor secretion, essentially the cells releasing signaling proteins that stimulate the surrounding neural environment to repair itself from within. Cardiac muscle operates under a similarly unforgiving rule. After a heart attack, the dead muscle tissue becomes fibrotic scar material. The heart compensates by making surviving muscle work harder, a process that gradually leads to enlargement, weakening, and eventual failure. Dental pulp stem cells introduced into cardiac tissue in multiple studies produced measurable reductions in scar formation and demonstrated the ability to differentiate into functional cardiomyocytes, beating in synchrony with native heart cells. Some studies recorded improved ejection fraction in animal models, the core measurement of how effectively the heart pumps blood. Bone regeneration represents the most clinically advanced application already moving toward human trials. Dental pulp stem cells express high levels of osteogenic markers and respond rapidly to bone morphogenetic proteins, the chemical messengers that trigger skeletal repair. Their application in craniofacial reconstruction, spinal fusion, and long bone defect repair is being studied across multiple institutions simultaneously. What separates these cells from other stem cell sources is the combination of accessibility and biological youth. Bone marrow aspiration requires sedation and produces significant post procedure pain. Umbilical cord blood requires planning around birth. Wisdom teeth emerge between 17 and 25, during peak cellular vitality, and come out during a procedure most people already schedule. The extraction window is permanent. Once the teeth are gone and the pulp degrades, that specific population of young, highly potent cells is irretrievable from that individual. Cryogenic preservation protocols now exist that maintain dental pulp stem cell viability for over two decades. Several countries have commercial dental stem cell banks operating with the same institutional model as cord blood banking, long term frozen storage, indexed against future therapeutic need. The science supporting the value of preservation is no longer speculative. What lags behind is public awareness and clinical infrastructure in markets where this remains obscure. The wider pattern is worth recognizing. Medicine has repeatedly discovered that profound biological tools were present in tissues it previously categorized as vestigial, unnecessary, or inconvenient. The appendix was considered evolutionary junk for over a century before researchers identified its role in gut microbiome preservation. Wisdom teeth carried the same dismissal, a developmental relic from ancestors who needed extra molars for coarse diets, relevant only in their capacity to cause orthodontic problems. The pulp inside them was never junk. It was a repair system the body built during youth and stored in one of the most protected anatomical locations, surrounded by enamel, the hardest substance the human body produces. Evolution rarely wastes that kind of architecture.show more

🚨 SCIENTISTS JUST REVERSED AGING IN BLOOD STEM CELLS... Researchers at Mount Sinai restored old blood stem cells to a youthful state by repairing tiny cellular recycling systems called lysosomes. In mice, aged stem cells regained the ability to: • regenerate healthy blood • rebuild immune cells • reduce inflammation • behave like young stem cells again One treatment increased blood-forming capacity by more than 8x. Why this matters: Your blood stem cells are responsible for constantly rebuilding your immune system and blood supply throughout life. As they age: • immunity weakens • inflammation rises • cancer risk increases • regeneration declines But this study suggests aging inside these cells may not be permanent. Scientists may have found a biological “reset switch.” The future of anti-aging may not come from replacing organs… …but from restoring the cells that rebuild the body itself.
