For much of modern biology, scientists argued that viruses are not alive, pointing to a basic limitation: they cannot make proteins on their own and must depend entirely on the cells they infect for ...

Researchers identified how the poxvirus protein VITF-3 forms a molecular ring that clamps onto DNA with viral RNA polymerase, bending it by 90 degrees to initiate gene copying.

A research team at the University of Würzburg has deciphered another aspect of poxviral gene activation. They have revealed a unique viral mechanism: A molecular ring anchors the viral copying machine ...

For almost 60 years, scientists have tried to understand why DNA doesn’t replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides, which happens constantly. Without this process, we would die.

A scientific experiment observing how white blood cells react under the microscope after exposure to food components, exploring cellular behavior in an educational and controlled way.

New NE-AFM method measures nuclear stiffness in living cells. It shows cancer nuclei change softness with chromatin and environment, aiding diagnosis and treatment. By employing a technique called ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...
