A Wake Forest University study found that poor readers' brains differ physiologically from normal readers, with the thalamus being less active. This could lead to pre-clinical diagnosis and understanding of reading genetics, stages of reading, and potentially therapeutic interventions for dyslexia.
Researchers at Sandia National Laboratories have created a method that purposefully unbalances reentry vehicles to steer them closer to targets, improving accuracy. The approach also enables the reorientation of satellites in space without changing their shape or requiring fuel.
A husband-and-wife team of psychiatrists are conducting a major population-based study to find the gene(s) linked to schizophrenia. The five-year study will be carried out in the Azores and on the Portuguese mainland, using genetic markers and genome-wide scans.
Sandia National Laboratories has released a CD-ROM containing over 60 megabytes of data gathered from downhole diagnostic tools used in 80% of domestic oil wells. The new tool provides valuable information about well bore dynamics and mechanical stresses on sucker rod strings, leading to equipment fatigue and rod failure.
Researchers successfully delivered genes encoding dopamine-producing enzymes into the brains of rats with induced Parkinson's disease, significantly reducing abnormal rotational movement. The treatment showed greater improvement when both genes were used together.
Researchers at Emory University report that a growth factor stimulation increases new neurons in the brain's striatum and cortex, raising hope for treating neurodegenerative diseases. The study confirms previous findings on adult mammalian forebrain's capacity to produce new neurons.
A study by University of Chicago researchers has shed light on the vital role of fat and cholesterol transport in maintaining healthy brain function. The team found that certain genetic variants, such as apoE4, can disrupt this process, leading to an increased risk of Alzheimer's disease.
Research at Emory University Health Sciences Center found that individuals with ADHD tend to integrate information in more visual and less auditory ways, which may explain their everyday difficulties. The study used PET scans to evaluate working memory in ADHD patients and normal control subjects.
The reserve protects diverse ecosystems and biodiversity, including indigenous communities and unique plant species. The establishment of the reserve demonstrates Brazil's commitment to preserving its natural heritage.
Researchers found a substantial genetic component underlying differences in fear response, particularly on chromosome 1, which may contain hundreds of genes. This discovery has implications for developing new pharmacological agents to target human genes implicated in fear-related disorders.
Researchers found that pallidotomy surgery for Parkinson's disease improves brain activity in areas responsible for controlling movement and decreases abnormal activation in cerebral areas. The study provides new insight into the brain mechanisms responsible for symptomatic improvement following surgery.
