How retroviruses become infectious

Understanding every step in the life cycle of a virus is crucial for identifying potential targets for treatment. Now, scientists at the Institute of Science and Technology (IST) Austria were able to show how a virus from ...

By adding strain, researchers improve metallic glass

Metallic glasses—materials with the strength of metal, but moldable like plastic—are being developed for a broad range of applications. Controlling the formation of metallic glasses and their resulting properties in bulk ...

Animal evolution—glimpses of ancient environments

Although amber looks like a somewhat unusual inorganic mineral, it is actually derived from an organic source—tree resins. Millions of years ago, when this aromatic and sticky substance was slowly oozing from coniferous ...
