Learning and memory problems in down syndrome linked to alterations in genome's 'dark matter'

Sciencedaily.com 

The activity of Snhg11, a gene found in the 'dark matter' of the genome, is critical for the function and formation of neurons in the hippocampus, specifically in an area critical for learning and memory. Researchers have discovered the gene is less active in brains with three copies of chromosome 21, which causes Down syndrome, potentially contributing to the condition's intellectual disabilities. The researchers plan on carrying out further research to discover the exact mechanisms of action involved... Читать дальше...

Diamonds are a chip's best friend

Sciencedaily.com 

New technologies aim to produce high-purity synthetic crystals that become excellent semiconductors when doped with impurities as electron donors or acceptors of other elements. Researchers have now determined the magnitude of the spin-orbit interaction in acceptor-bound excitons in a semiconductor. They broke through the energy resolution limit of conventional luminescence measurements by directly observing the fine structure of bound excitons in boron-doped blue diamond, using optical absorption.
