A new imaging technique opens a path toward long-term study of blood vessels in aging brains and could help predict neurodegenerative diseases decades before symptoms begin.
One of the most expensive steps in manufacturing protein drugs such as antibodies or insulin is the purification step: isolating the protein from the bioreactor used to produce it. This step can accou...
Our brains are charged with the task of directing most of the processes needed for our bodies to function. As such, they consume roughly 20% of our body’s metabolic energy, even while we’re resting.
In recent years, scientists who study gene expression in cells have used a method that essentially pins a tail on RNA and tracks their whereabouts. However, certain types of RNA evade the process. Now...
