The article, published in Brain Pathology, describes how SAFB1 expression occurs in both spinocerebellar ataxias and Huntington's disease and may be a common marker of these conditions, which have a similar genetic background. SAFB1 is an important protein controlling gene regulation in the brain and is similar in structure to other […]

USC researchers peering deep inside a living cell have discovered something surprising: Its system for preventing genetic damage linked to diseases can fail so badly that the cell would be better off without it. It’s a paradoxical finding because it challenges the idea that tiny protein guardians of cell division […]

Scientists from the USC Stem Cell laboratories of Neil Segil and Justin Ichida are whispering the secrets of a simpler way to generate the sensory cells of the inner ear. Their approach uses direct reprogramming to produce sensory cells known as “hair cells,” due to their hair-like protrusions that sense sound waves. The study was published […]

Aging sucks. Your entire body starts deteriorating and it’s sad. There is nothing good about aging. But probably the worst part is the decline of cognitive abilities. Losing the sharpness of your mind is truly heartbreaking, but millions and millions of people are facing the inevitability of dementia. However, scientists […]

Companies often outsource some of their activities. It means that some parts of their work are done by other organizations, typically where labour is cheaper or there are other incentives. But humans outsource some of their activities too. Scientists from the University of Queensland found that children begin outsourcing thinking […]

Pretty much half of us is going to get cancer. This is part and parcel of our stressful lifestyle as well as aging. Some substances around us are very efficient in causing cancer. But why is that? Why some chemicals are able to cause cancer, which occurs when errors happen […]
