In a landmark discovery, researchers at Tel Aviv University have unraveled the metastatic mechanism of melanoma, the most aggressive of all skin cancers. According to a paper published today in the journal Nature Cell Biology, the scientists discovered that before spreading to other organs, a melanoma tumor sends out tiny vesicles containing molecules of microRNA.

The search for habitable, alien worlds needs to make room for a second “Goldilocks,” according to a Yale University researcher. For decades, it has been thought that the key factor in determining whether a planet can support life was its distance from its sun. In our solar system, for instance, Venus is too close to […]

There’s nowhere to hide in the open ocean, far from the shore or the seafloor. But some fish have a clever disappearing trick. The silvery skin of fish like herring, sardines, […]
Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history, according to computer modeling of the planet’s ancient climate by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. The findings, published this week in the journal Geophysical Research Letters, […]
