Yet concerns for these patients remain. Up to half of people with HIV on these drug regimens have some sort of cognitive impairment, such as memory loss or… Read more

Shedding light on possible contributors to autism, schizophrenia and other neuro-psychiatric disorders, researchers have found that a type of support cell abundant in the brain may play a role in the ability of neurons to communicate. The team of scientists, at Washington University School of Medicine in St. Louis found, in culture, that without these… Read more

As we grow, our brain cells develop different genomes from one another, according to new research from Harvard Medical School and Boston Children’s Hospital. The study shows, for the first time, that mutations in somatic cells, that is, any cell in the body except sperm and eggs, are present in significant numbers in the brains… Read more

Fibrous protein clumps known as amyloids are most often associated with diseases such as Alzheimer’s disease, where they form characteristic plaques in the brain. Scientists first described amyloids about 150 years ago; they have since been tagged as key players in Parkinson’s disease, Huntington’s disease, and rheumatoid arthritis, as well as Alzheimer’s. However, recent findings… Read more

Liquid crystals are familiar to most of us as the somewhat humdrum stuff used to make computer displays and TVs. Even for scientists, it has not been easy to find other uses. Now a group of researchers is putting liquid crystals to work in a completely unexpected realm: as detectors for the protein fibers implicated… Read more
