Revealing the structure of axons

Recent studies have shown that under the axonal membrane, rings composed of actin filaments give the structure its flexibility. But those studies had not been able to define the precise architecture of these rings. By combining ...

The filaments that structure DNA

They play a leading role not only in muscle cells: Actin filaments are one of the most abundant proteins in all mammalian cells. The filigree structures form an important part of the cytoskeleton and locomotor system. Cell ...

The mechanism of cellular migration mode switching

When faced with difficult terrain, off-road vehicles can switch from two- to four-wheel drive to keep moving forward. Similarly, cell migration can be driven either by protrusion-directed crawling, or by contractile pulling ...

Acoustic waves can monitor stiffness of living cells

MIT engineers have devised a new, noninvasive way to measure the stiffness of living cells using acoustic waves. Their technique allows them to monitor single cells over several generations and investigate how stiffness changes ...

Morphological transitions of biological filaments under flow

The study of complex suspensions made of particles suspended in a simple fluid has been growing lately, with many opportunities for industry or lab-on-a-chip technology. The macroscopic flow properties of these suspensions ...
