The enzyme that produces DNA building blocks plays an important role when cells divide. In a new study, researchers have discovered for the first time that the so-called master switch of the enzyme can change locations -- while still performing the same task.
In the Christopher Nolan film Memento (2000) the protagonist suffers from long-term memory loss and is unable to retain new memories for no longer than a few minutes. The events unfold in reversed chronological order. The results deepen our understanding of how the brain functions, how narratives work in film, and memory mechanisms impaired by conditions such as Alzheimer's disease.
Sipping wine is good for your colon and heart, possibly because of the beverage's abundant and structurally diverse polyphenols. Now researchers report that wine polyphenols might also be good for your oral health.
Modern humans have brains that are more than three times larger than our closest living relatives, chimpanzees and bonobos. Scientists don't agree on when and how this dramatic increase took place, but new analysis of 94 hominin fossils shows that average brain size increased gradually and consistently over the past three million years.
Axonal and dendritic proteins embedded in the membrane at either end -- called transmembrane proteins -- are built in the same cellular factory and travel on the same cellular highway. But for the cell to function property, they must be delivered to the correct domain. So how does the cell regulate that voyage?
Alcohol use disorders are the most important preventable risk factors for the onset of all types of dementia, especially early-onset dementia. This according to a nationwide observational study of over one million adults diagnosed with dementia in France.
Levels of a protein found in the brain called alpha-synuclein are significantly lower than normal in cerebrospinal fluid collected in Parkinson's disease patients suffering from postural instability and gait difficulty, a study has found.
