DNA’s two strands must be separated before its code can be read, or transcribed. By studying the structure of the enzyme RNA polymerase, researchers have elucidated how DNA unwinds and becomes legible.
Geckos are amazingly agile. In addition to running across land and up trees, the animals can prance across the surface of water. A new study reveals how they do it.
Scientists have made the first comprehensive inventory of cells present in the human placenta of the first trimester, a stage when many pregnancy complications are thought to arise. The findings could fuel new research on conditions such as preeclampsia and pre-term birth.
The gateway to cellular headquarters has 552 components. A new map that shows how all these pieces fit together could help scientists study numerous diseases.
A new report details three cases of secondary brain tumors in people with fibrolamellar hepatocellular carcinoma. The researchers say imaging tests could improve treatment for patients whose cancer spreads to the brain from the liver.
In discovering how an antibiotic kills the bacteria that cause tuberculosis, scientists open the door to new treatments for the disease—and possibly others, as well.
