A new study led by researchers from the Yunnan Observatories of the Chinese Academy of Sciences has unveiled a novel ...

Researchers have unearthed a robust physics-based mechanism that dictates the sliding strength, or resistance to slippage, of the most common type of surgical knot. In particular, they have found that ...

The mechanism to do this is fascinating, consisting of a sector gear with racks on either side. The racks are alternately engaged by the sector gear, moving a PTFE filament guide tube back and ...

Figure 4: The relative positioning of mitotic centrosomes is determined by a balance of microtubule–microtubule sliding motors.

They demonstrated that, although the well-known thin-filament mechanism is sufficient for regulation of muscle shortening against low load, force generation against high load requires a second ...

The protein scissors have an internal timer mechanism that is activated upon the binding of signaling molecules and filament formation. This mechanism is unique compared to other similar signal ...

The sliding force is generated via cyclic interactions of myosin heads projecting from the thick filament with actin molecules on the thin filaments.

In summary, these findings provide important insights into the mechanisms underlying Dmc1 filament assembly and functioning of its accessory proteins.
