Euchromatin is not really open in living cells, shows study

DNA and associated proteins in active regions of the genome are condensed but behave like a viscous liquid at the molecular level. This finding greatly increases our understanding of the physical nature of expressed genome ...

Modelling micro-swimmers for drug delivery

Mathematical models of the motion of cells in viscous liquids that show how this motion is affected by the presence of a surfactant coating have applications in the design of artificial micro-swimmers for targeted drug delivery, ...

Potholes: How engineers are working to fill in the gaps

Potholes are a perennial problem. They are dangerous to road users, and the damage they cause to vehicles can be hugely expensive. The cost of repairing them is also vast. But still they appear, and reappear, in countless ...

Levitation trick gives drag the slip

Plunging hot spheres into viscous liquids reveals a way to reduce fluid resistance without complex engineering procedures.
