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 ...

Bacteria must be 'stressed out' to divide

A new study from EPFL scientists has found that bacteria use mechanical forces to divide, along with biological factors. The research, led by the groups of John McKinney and Georg Fantner at EPFL, came after recent studies ...

DNA 'origami' takes flight in emerging field of nano machines

Just as the steam engine set the stage for the Industrial Revolution, and micro transistors sparked the digital age, nanoscale devices made from DNA are opening up a new era in bio-medical research and materials science.
