Harvard scientists uncover key allowing deadly viruses to replicate

Viruses are masterful invaders. They cannibalize host cells by injecting their genetic material, often making thousands of copies of themselves in a single cell to ensure their replication and survival. Some RNA viruses — viruses whose RNA, not DNA, carries their genetic information — insert their genetic material into cells as a single piece, while… Read More »

But the speed at which we can noninvasively follow brain function using an MRI is not as impressive. Functional MRI (fMRI), which measures changes in blood-oxygen… Read More »
