Tissues protect their DNA under mechanical stress

In everyday life, our tissues, for example, skin and muscle, are stretched, pulled and compressed without causing damage to the cells or the DNA. A team of researchers led by Sara Wickström from the Max Planck Institute ...

Making cells ultra-heavy

The life of a fibroblast is heavy, but PhD student Julia Eckert makes it 19.5 times heavier, using the Large Diameter Centrifuge at the ESTEC space research centre in Noordwijk.

Mathematical model helps to explain the formation of spine and ribs

At an early stage in vertebrates' embryonic development somites form: these are primitive segments from which the spine, ribs, back muscles, cartilage, tendons and part of the skin develop. It is known that mechanical forces ...

Stimulating resonance with two very different forces

Widely studied in many different fields, 'nonlinear' systems can display excessively dramatic responses when the forces which cause them to vibrate are changed. Some of these systems are sensitive to changes in the very parameters ...

The 'airbag' that protects cells against stress

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have identified the molecular mechanisms that allow cells to survive mechanical stress. The results, published today in Nature Communications, show ...
