...thing more sophisticated. Efficient processing and storing of microarray data, as well as the ability to easily retrieve and compare data with other experiments were all required. New information about genes spotted on the slides is continuously discovered and needs to be incorporated into data from previous...Reductions in blood oxygen levels in newborns could contribute to ADHD development
...nstead of releasing dopamine, they were abnormally storing it. "By linking reductions in blood oxygen during critical times of development to changes in dopamine function, we hope to shed light on the mechanisms of ADHD, which have been poorly understood to this point," said Dr. Keating. "Our results sho...Findings show how toxic proteins rob Alzheimer's patients of memory
...ADDLed synapses have trouble staying connected and storing memories." ADDLS are small, soluble aggregated proteins. The clinical data strongly support a recent theory in which ADDLs accumulate at the beginning of Alzheimer's disease and block memory function by a process predicted to be reversible. ...NU researcher finds missing atmospheric carbon dioxide
...searchers sought to determine if the mechanism for storing carbon in soil was CO2 fertilization, the process by which plants grow better when exposed to high CO2 levels, and to investigate the extent to which CO2 fertilization could be increasing the amount of carbon stored in soil under white oak trees.

The mice with more lipin in their muscle grew obese because the gene repressed their metabolism, causing them to burn fewer calories tha...Man-made wetland's effectiveness similar to natural marsh
