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 ...

Embryonic tissue undergoes phase transition

When scientists at the Institute of Science and Technology (IST) Austria looked at developing zebrafish embryos, they observed an abrupt and dramatic change: Within just a few minutes, the solid-like embryonic tissue becomes ...

A plant's way to its favorite food

Nitrogen is one the most essential nutrients for plants. Its availability in the soil plays a major role in plant growth and development, thereby affecting agricultural productivity. Scientists at the IST Austria were now ...

Frozen: Cutting-edge technology reveals structures within cells

Temperatures of -196 degrees Celsius enable high-resolution imaging of the cell's interior. Researchers at the Institute of Science and Technology (IST) Austria are thus able to show for the first time how the active form ...

New compact model for gene regulation in higher organisms

Although the DNA and its double-helix are one of the most familiar molecules of our time, our knowledge of how cells control what genes they want to express is still rather limited. In order to create, for example, an enzyme, ...

Plants on aspirin

When pathogens enter a plant, infected cells set off an alarm before they die. They discharge methylsalicylic acid, which is later transformed into salicylic acid, triggering an immune response. Hence, salicylic acid is a ...

Scientists discover how tissue tension controls cell division

During cell division, a parent cell divides into two daughter cells. Their new role and function depend on the orientation of the division plane. A crucial factor guiding this division orientation is the shape of the mother ...

Molecular compass for cell orientation

Plants have veins that transport nutrients throughout their whole body. These veins are organized in a highly ordered manner. The plant hormone auxin travels directionally from cell-to-cell and provides cells with positional ...
