Double-action mechanism found that makes ketamine less addictive
Posted by ArielTechGeek 8 days ago (https://newatlas.com)
MIT scientists have uncovered a mechanism for how a common genetic risk factor for Alzheimer’s contributes to the disease. It centers on lipid metabolism, and early investigations suggest it could eventually lead to new treatments to slow disease progression.Continue ReadingCategory: Medical, ScienceTags: Alzheimer's Disease, Disease, Neuroscience, Brain, MIT, Genetics

Alzheimer’s-preventing nasal spray targets novel brain mechanism
Posted by ArielTechGeek 126 days ago (https://newatlas.com)
An international team of researchers has reported on the successful preclinical tests of a novel nasal spray developed to prevent neurodegeneration associated with Alzheimer’s disease. The treatment was effective at reversing the pathological signs of Alzheimer’s in mouse models and the researchers are looking to start human tests in two years.Continue ReadingCategory: ScienceTags: Alzheimer&apos
Anti-aging mechanism of calorie restriction identified in Yale study
Posted by ArielTechGeek 183 days ago (https://newatlas.com)
Animal studies have consistently demonstrated calorie-controlled diets lead to better health and longer lifespans. Human trials testing different dietary regimes have established calorie restriction as an effective way to lose weight, but it hasn’t been clear if long-term calorie restricted diets generate the same systemic health benefits in humans as seen in animal studies.Continue ReadingCatego
Newly discovered microbiome mechanism found to block common diabetes drug
Posted by ArielTechGeek 234 days ago (https://newatlas.com)
Impressive new research, spearheaded by a team from Princeton University, has shown how a common diabetes drug can be inactivated by bacterial enzymes produced in the oral and gut microbiome. The researchers speculate this process may explain why the drug is not effective in some diabetic patients.Continue ReadingCategory: Health & Wellbeing, LifestyleTags: Gut Bacteria, Microbiome, Diabetes,
Tiny punching "robot" mimics the mechanism of the mantis shrimp
Posted by ArielTechGeek 352 days ago (https://newatlas.com)
Among other things, the mantis shrimp is known for having the fastest punch of any animal. Harvard scientists have now built a mechanism that simulates that punch, and they believe that it could lead to new capabilities for human technologies.Continue ReadingCategory: ScienceTags: Harvard, Robotics, Biomimicry
Left: The barrier mechanism when it's closed; Right: The barrier mechanism when it's open.Canon has filed a new patent application for an in-camera mechanism designed to protect the shutter and image sensor of its mirrorless cameras from dust and debris when no lens is attached.Japanese patent application number 2019–234718 describes (machine-translated) an ‘invention related to interchangeable l
New repair mechanism discovered in the brain could one day treat seizures
Posted by ArielTechGeek 383 days ago (https://newatlas.com)
Researchers at the University of Virginia may have discovered a previously unknown repair mechanism at work in the brain. Immune cells called microglia were observed moving beyond their known roles and helping injured neurons heal, potentially paving the way for new treatments for epilepsy and other conditions.Continue ReadingCategory: Medical, ScienceTags: Brain, Epilepsy, Neuroscience, The Immu
New mechanism controls superbugs by sparing the death sentence
Posted by ArielTechGeek 417 days ago (https://newatlas.com)
Antibiotics are reaching the limits of their usefulness, as they drive bacteria to evolve into new drug-resistant forms. But a new study has uncovered a mechanism that could make the bugs non-infectious without killing them, reducing the evolutionary pressure that leads to superbugs.Continue ReadingCategory: Medical, ScienceTags: University of Geneva, Bacteria, Antibiotic-resistant bacteria, Supe
