Understanding the nature of consciousness is one of the hardest problems in science. Some scientists have suggested that quantum mechanics, and in particular quantum entanglement, is the key to unraveling the phenomenon. https://phys.org/news/2024-08-photon-entanglement-rapid-brain-consciousness.html General Physics Fri, 16 Aug 2024 08:55:03 EDT news643017296 Drugs available to treat multiple sclerosis, a leading cause of neurological disability affecting roughly 2.3 million people worldwide, alter the body's immune system to reduce disease symptoms and disability. https://phys.org/news/2018-05-chemical-compound-beneficial-inflammation-remyelination.html Biochemistry Tue, 29 May 2018 15:56:50 EDT news446828201 Researchers have developed a fast and practical molecular-scale imaging technique that could let scientists view never-before-seen dynamics of biological processes involved in neurodegenerative diseases such as Alzheimer's disease and multiple sclerosis. https://phys.org/news/2017-07-imaging-technique-molecular-dynamics-neurodegenerative.html Optics & Photonics Thu, 13 Jul 2017 10:00:01 EDT news419139211 (Phys.org)—If a metallurgist wanted to determine how a blade was made they might cut a small cross section, mount, polish, and etch it, and then look at it under a microscope. They could probably tell right away whether it was forged, cast, or perhaps even 3D printed. If the blade was of a particularly high quality, like a Samurai sword, they could see the multiple layers that were created the through laborious cycles of heating, hammering and refolding that are typically used to optimize the grain structure for both toughness, hardness, and grain orientation. The point here is that the structure evident in the Samurai sword cross section didn't just passively polymerize out of thin air like a snowflake, or get made by some other passive thermochemical series of events, it took a more directed driving force. https://phys.org/news/2015-07-myelination-actin-disassembly.html Cell & Microbiology Mon, 27 Jul 2015 09:20:02 EDT news357187400 The development of a new cell-culture system that mimics how specific nerve cell fibers in the brain become coated with protective myelin opens up new avenues of research about multiple sclerosis. Initial findings suggest that myelin regulates a key protein involved in sending long-distance signals. https://phys.org/news/2011-07-ms-myelin-brain-cells.html Biochemistry Thu, 21 Jul 2011 15:53:10 EDT news230482376 Laboratory studies by chemical engineers at UC Santa Barbara may lead to new experimental methods for early detection and diagnosis -- and to possible treatments -- for pathological tissues that are precursors to multiple sclerosis and similar diseases. https://phys.org/news/2011-05-nanoscale-imaging-treatments-multiple-sclerosis.html Bio & Medicine Mon, 23 May 2011 16:09:14 EDT news225385728
