A study team of radiologists and psychologists has found that children born with DNA copy number deletions in a specific region on chromosome 16 previously linked to neurodevelopmental problems show measurable delays in processing sound and language [1].
Last month, the National Institutes of Health, 10 biopharmaceutical companies and several nonprofit organizations launched an unprecedented partnership to transform the current model for identifying and validating the most promising biological targets of disease for new diagnostics and drug development.
Mitochondria are specialized subunits inside a cell that produce the cell’s energy and regulate its metabolism. Research suggests that mitochondria may play a central role in neuronal cell survival because they regulate both energy metabolism and cell death pathways. Using genetic mouse models of Alzheimer’s disease, researchers from Mayo Clinic have found that mitochondria in the brain are dysfunctional early in the disease. The findings were recently published in the open access journal PLoS ONE.
Regardless of high or low overall scores on an IQ test, children with dyslexia show similar patterns of brain activity, according to researchers supported by the National Institutes of Health. The results call into question the discrepancy model — the practice of classifying a child as dyslexic on the basis of a lag between reading ability and overall IQ scores.
In President Barack Obama’s State of the Union address last month, he argued that government support for research and development to fund innovation is a necessary and critical investment that must be made, even in the face of a rising national debt. A coalition of biomedical researchers support his vision on science. The 2012 budget President Obama sent to Congress earlier this month seeks an increase in funding for biomedical research at the National Institutes of Health (NIH) and in basic science at other agencies, while making cuts and freezes in many other areas of government.
