Researchers Closing In On Gene For Paralytic Disorder

Scientists have mapped a defective gene responsible for hereditary amyotrophic lateral sclerosis (ALS) to chromosome 9, bringing closer the isolation of the gene and potential treatment options. The gene is suspected to be linked to similar neurodegenerative disorders, with symptoms appearing in childhood but never being fatal.

New Software Makes More Reliable Cast Metal Parts

Researchers at Ohio State University have developed a fast new method to analyze part designs and locate potential defects that may form in die-cast metal parts. The binary voxel model uses geometry to simulate die casting, producing an image with color-coded areas of concern. This method can identify weak spots in seconds, unlike more...

Personality, Thought To Be Stable Over Time, Changes In Healthy People Who Take A Widely Used Anti-Depressant

Researchers found that a widely used anti-depressant can alter personality traits in healthy individuals, making them more easy-going and cooperative. The study, led by UCSF researchers, suggests that psychopharmaceuticals may affect different aspects of normal personality through distinct neural pathways.
