Five Facts About the Microbiome

UNKNOWN PROTEINS As scientists sequence DNA in microbiome samples, they are discovering new building blocks of life. About 30 percent of the genes in genomes sequenced in large-scale studies code for proteins that are new to science. MICROBES IN HUMANS Estimates of the number of nonhuman cells in our bodies range from 30 trillion to […]

They are glioblastoma cells, agents of the same disease that killed Senator Ted Kennedy. “Glioblastoma cells are very effective at invading the neighboring tissue of the brain,” says Greenwood. “In many cases, these cells sprint.” Although surgery is often […]
