Equally significant, when cells made more syt-17, axon growth accelerated. A wide range of neurological conditions could benefit from the growth of axons, including spinal cord injuries and some neurodegenerative diseases.

Ljudning är A och O för att knäcka läskoden

En gång i tiden fick alla barn som började skolan samma läsebok och något av det första de fick lära sig läsa var ”far är rar” och ”mor ror”. Idag används många olika utbildningsmaterial i klassrummen. Till exempel metoder som betonar textens innehåll och där eleverna får gissa och använda bilder för att förstå innehållet. Men det är metoder som saknar vetenskapligt bevisad effekt. Den enda metod

Circulation of water in deep Earth's interior

Phase H is a hydrous mineral that is considered to be an important carrier of water into deep Earth. We determined the dissociation condition of phase H by a theoretical calculation based on quantum mechanics. Phase H decomposes at approximately 60 GPa at 1000 K. This indicates that the transportation of water by phase H may be terminated at a depth of approximately 1,500 km in the middle of the l

Chemical and physical origins of friction on surfaces with atomic steps

Friction results from a set of complex processes that act together to resist relative motion. Despite this complexity, friction is often described using simple phenomenological expressions that relate normal and lateral forces via the friction coefficient. The defined parameter encompasses multiple, sometimes competing effects. To better understand the origins of friction, Zhe Chen and an interdis
