Study explains how geckos gracefully gallop on water

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.

Shape-shifting protein protects bacteria from invaders

Researchers have discovered how bacteria manage to destroy enemy DNA, while keeping their own genetic material safe.

First mapping of cells in the early human placenta to advance research on problem pregnancies

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.

New method for studying gene expression could improve understanding of brain disease

By analyzing gene expression patterns, researchers have identified previously unknown distinctions between mouse and human neurons. They have also developed a new way to track cellular changes associated with brain disorders.

Enzyme structure helps to explain how protein factories are constructed

Researchers characterized the structure of Mdn1, an enzyme key to making ribosomes.

Gaby Maimon and Luciano Marraffini are named HHMI investigators

Maimon, who studies cognition and decision-making, and Marraffini, who studies the bacterial defense system CRISPR-Cas, are among 19 scientists nationwide to receive this designation.

What happens to a dying cell’s corpse? New findings illuminate an old problem

Scientists have discovered a curious way for cells to die. In studying it, they are learning about how remnants of diseased cells are normally chewed up and removed.

Scientists map the portal to the cell’s nucleus

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.

Scientists caution that a rare childhood liver cancer can spread to the brain

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 brief: Tweaking RNA protects cells from harmful inflammation

New research has helped explain what goes wrong in Aicardi-Goutières syndrome, a rare brain disorder. Patients with the disease have genetic abnormalities that may put their cells at risk of accidentally triggering an antiviral response.
