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.

How the dragon got its frill

The frilled dragon exhibits a distinctive large erectile ruff. This lizard usually keeps the frill folded back against its body, but can spread it as a spectacular display to scare off predators. Researchers at the University ...

How do muscle and tendon connections last a lifetime?

Muscles are connected to tendons to power animal movements such as running, swimming or flying. Forces are produced by contractile chains of the proteins actin and myosin, which pull on muscle-tendon connections called attachments. ...

Converting biomass by applying mechanical force

One of the greatest global challenges is the efficient use of renewable sources in order to meet the increasing demand for energy and feedstock chemicals in the future. In this context, biomass is a promising alternative ...

Study identifies a 'sensor' that activates cell migration

The cytoskeleton is a structure that not only helps cells maintain their shape and internal organisation, but also enables them to perform functions like movement and migration to sites far from the place where they originated. ...

Putting cells under pressure

As cells divide to form tissues and organs in multicell organisms, they move to where they belong, informed by a series of cues that scientists have yet to observe or fully understand.
